Searching for an Askar CMOS astro camera can lead to a broader question: which astronomy camera best matches your telescope, targets, and imaging workflow? The five cameras here are from ZWO and SVBONY, not Askar, so I’m comparing them as alternatives rather than presenting them as Askar products. My strongest deep-sky pick is the SVBONY SC571CC, with its large cooled APS-C sensor; the ZWO ASI183MC-Pro is a high-resolution cooled choice for buyers who value fine detail; and the ZWO ASI676MC stands apart for square-format all-sky and meteor recording.

The main tradeoff is between sensor area and cooling for faint deep-sky work, and small, fast sensors that suit lunar, planetary, or meteor capture. A cooled camera needs extra power and a more involved setup, while a compact uncooled model is simpler but less tailored to long exposures. I’ve ranked these options by how clearly each one serves a particular imaging job, not by treating every camera as interchangeable.
Key Takeaways
- Best deep-sky fit: The SVBONY SC571CC pairs a 26 MP APS-C sensor with dual-stage cooling, a dew-control heater, and a 512 MB buffer.
- Best high-resolution cooled alternative: The ZWO ASI183MC-Pro offers 20.1 MP and cooling, but its 2.4-micron pixels and separate cooler power supply shape the setup.
- Best for all-sky and meteor capture: The ZWO ASI676MC combines a square 12.6 MP sensor, 31.2 fps, very low read noise, and no amp glow.
- Best for compact high-speed capture: The ZWO ASI715MC reaches 45.1 fps, but its small 1/2.8-inch sensor is a narrower match for wide-field imaging.
- Best square cooled alternative: The SVBONY SV605CC has a cooled 1-inch, 9 MP sensor, though its listed 1.6 kg weight may challenge lighter mounts.

More Details on Our Top Picks
SVBONY SC571CC Cooled Color Astronomy Camera with IMX571 APS-C Sensor
I put the SC571CC first because it offers the broadest deep-sky imaging package in this group: a 26 MP APS-C back-illuminated sensor, dual-stage TEC cooling, 16-bit conversion, and a 512 MB buffer. Its larger sensor area can frame more sky than the 1-inch SV605CC or the much smaller ASI715MC, which is helpful when a telescope’s focal length and target call for a wider field. Cooling and the zero-amp-glow design are aimed at cleaner long-exposure capture, while the front-window heater addresses dew without relying only on external remedies.
Compared with the ASI183MC-Pro, the SC571CC gives up the ZWO’s stated 20.1 MP detail emphasis in favor of more sensor area, larger 3.76-micron pixels, and a more expansive overall deep-sky setup. Its specified cooling reaches up to 35°C below ambient, so the number is not a fixed sensor temperature; actual performance depends on ambient conditions. I would choose this model for a dedicated, compatible imaging rig, not as a casual plug-in camera. Its bigger sensor and cooling features do not remove the need to match the telescope, mount, power, software, and back focus.
Pros:- 26 MP APS-C sensor provides more imaging area than the 1-inch and small-format options here.
- Dual-stage TEC cooling and zero-amp-glow design suit long-exposure deep-sky work.
- Software-controlled front-window heater helps manage dew on the camera window.
- 16-bit ADC and 512 MB buffer support a capable capture workflow.
Cons:- Requires a compatible telescope and a more involved imaging setup.
- Cooling is specified relative to ambient temperature, so it does not promise one fixed operating temperature.
- Large sensor use can demand careful optical and back-focus matching.
Best for: Deep-sky imagers who want a cooled APS-C color sensor, broad framing, and an integrated dew-control heater.
Not ideal for: Beginners seeking the simplest lightweight camera, or buyers whose telescope and mount cannot support an APS-C imaging setup.
- Sensor:Sony IMX571 APS-C BSI CMOS
- Resolution:26 MP
- Sensor area:23.4 × 15.7 mm
- Pixel size:3.76 µm
- Cooling:Dual-stage TEC, up to 35°C below ambient
- ADC:16-bit
- Buffer:512 MB DDR3
- Interface:USB 3.0
Our verdict“I rank the SC571CC first for deep-sky buyers who can support its APS-C sensor and want cooling, image area, and dew control in one camera.”
ZWO ASI183MC-Pro 20.1 MP Cooled Color Astronomy Camera
The ASI183MC-Pro earns second place for buyers who prioritize a high pixel count and cooling but do not need the SC571CC’s larger APS-C area. Its 20.1 MP sensor and 2.4-micron pixels give imagers a detailed sampling option, particularly when the telescope and seeing conditions can make use of that resolution. TEC cooling, a 256 MB buffer, and USB 3.0 make it more suited to planned deep-sky sessions than a simple uncooled planetary camera.
Its tradeoffs are unusually practical: the cooler needs a separate 12 V, 3 A power supply, even though the camera electronics connect through USB 3.0. That extra power requirement adds cable and field setup considerations absent from the uncooled ASI676MC and ASI715MC. The SC571CC is the stronger choice if a wider APS-C field and newer listed capture features matter more; the ASI183MC-Pro makes more sense when its smaller pixels and 20.1 MP resolution suit the intended framing. It can also capture the Moon and Sun, but solar imaging requires a separate solar filter, which is not included.
Pros:- 20.1 MP resolution records fine detail when paired with suitable optics and conditions.
- TEC cooling is designed to reduce sensor noise during faint-object imaging.
- USB 3.0 and a 256 MB buffer support high-speed data transfer.
- Compact aluminum body and included adapters support 1.25-inch and 2-inch focusers.
Cons:- TEC cooling requires a separate 12 V, 3 A supply.
- Solar filter and optional autoguiding camera are not included.
- Its smaller sensor area gives less framing coverage than the SC571CC APS-C sensor.
Best for: Deep-sky imagers who want a cooled 20.1 MP color camera with small pixels for fine sampling.
Not ideal for: Buyers who need a self-contained field setup, do not want a separate cooler power supply, or expect solar accessories in the box.
- Sensor:CMOS color
- Resolution:5496 × 3672 pixels, 20.1 MP
- Pixel size:2.4 microns
- Cooling:TEC cooling, 40–45°C below ambient
- Maximum frame rate:19 fps at maximum resolution
- Buffer:256 MB DDR3
- Connections:USB 3.0; separate USB 2.0 hub
- Power:USB 3.0 for camera electronics; separate 12 V, 3 A supply for TEC cooler
Our verdict“I recommend the ASI183MC-Pro for detail-focused buyers who want cooling and can accommodate its separate power supply.”
ZWO ASI676MC 12.6 MP CMOS Color Astronomy Camera
The ASI676MC is the most purpose-built option here for all-sky surveillance and meteor recording. Its 12.6 MP sensor uses a square 3552 × 3552 layout, which can simplify framing and mosaic planning compared with the rectangular ASI715MC. The camera’s stated 31.2 fps, 0.56-electron read noise, 83% quantum efficiency, and no-amp-glow design point toward capturing faint or fast-changing sky events. That combination gives it a different job from the cooled deep-sky cameras: it emphasizes sensitivity and capture speed rather than long-exposure TEC cooling.
Compared with the ASI715MC, the ASI676MC has a larger square-format sensor and a lower stated frame rate; the ASI715MC reaches 45.1 fps and may appeal more for fast capture at its own smaller format. Against the cooled SV605CC, the ASI676MC avoids a cooler-focused setup but also lacks cooling for long deep-sky exposures. Its UV/IR-cut coated window is specified at 21 mm diameter, and the camera is not water resistant, so all-sky installations need suitable protection. I would select it for a supported sky-monitoring setup, not assume it can be left exposed to weather.
Pros:- Square 12.6 MP sensor supports straightforward all-sky framing and mosaic planning.
- Very low stated read noise and no amp glow suit sensitive capture.
- 31.2 fps, USB 3.0, and a 256 MB cache support rapid data collection.
- 83% quantum efficiency and enhanced near-infrared sensitivity broaden capture potential.
Cons:- Not water resistant, so outdoor monitoring requires protective housing.
- No image stabilization.
- Uncooled design is less tailored to long-exposure deep-sky imaging than the SC571CC or SV605CC.
Best for: Observers recording meteors, monitoring the whole sky, or wanting a square sensor for sky coverage and mosaics.
Not ideal for: Deep-sky imagers whose main priority is a cooled sensor, or anyone planning exposed outdoor use without weather protection.
- Sensor:Sony IMX676, 1/1.6-inch
- Resolution:3552 × 3552, 12.6 MP
- Pixel size:2 µm
- Quantum efficiency:83%
- Read noise:0.56 e-
- Frame rate:31.2 FPS
- Interface and cache:USB 3.0; 256 MB DDR3
- ADC:12-bit
Our verdict“I rank the ASI676MC as the best specialist choice for all-sky and meteor work, rather than as a general replacement for a cooled deep-sky camera.”
SVBONY SV605CC Cooled Color Astrophotography Camera
The SV605CC brings cooling to a more modest 9 MP square sensor. Its 1-inch IMX533 format produces 3008 × 3008 images, giving a balanced square frame for deep-sky targets, panoramic work, and some meteor or lucky-imaging uses. Two-stage semiconductor cooling is specified up to 30°C below ambient, and the product description says the sensor design suppresses amp glow. Compared with the larger SC571CC, this camera gives up APS-C coverage and resolution, but its square 1-inch sensor may be easier to frame around for a buyer who does not need the broader field.
It is also a different proposition from the uncooled ASI676MC: the SV605CC is the more relevant choice for buyers placing cooling ahead of all-sky speed, while the ASI676MC has a higher stated frame rate and much lower listed read noise. The main concern is the stated 1.6 kg weight, which can matter on a small telescope, focuser, or mount and should be checked against the full imaging train. This is not a lightweight camera for every rig. I would shortlist it for a compatible, stable setup where a cooled square sensor matters more than APS-C area or a compact payload.
Pros:- Square 9 MP IMX533 sensor gives a useful 3008 × 3008 imaging format.
- Two-stage cooling reaches up to 30°C below ambient to support deep-sky work.
- Designed to suppress amp glow and also suited to panoramic and meteor imaging.
- USB 3.0 connection supports computer-based capture.
Cons:- Listed 1.6 kg weight may be substantial for lighter telescope systems.
- Its 9 MP sensor has less area and resolution than the SC571CC APS-C camera.
- Requires a compatible telescope and imaging setup.
Best for: Deep-sky and panoramic imagers who want a cooled 1-inch square color sensor in a compatible, sturdy setup.
Not ideal for: Owners of lightweight mounts or focusers, and buyers who need the larger sensor area or heater features of the SC571CC.
- Sensor:IMX533 color, 1-inch
- Resolution:9 MP, 3008 × 3008
- Pixel size:3.76 μm
- Quantum efficiency:Up to 80%
- Cooling:Two-stage semiconductor cooling, up to 30°C below ambient
- Connectivity:USB 3.0
- Weight:1.6 kg listed
- Enclosure:Aluminum
Our verdict“I recommend the SV605CC when a cooled square sensor is the priority and the stated camera weight suits the imaging train.”
ZWO ASI715MC 8.46 MP Color Astronomy Camera
The ASI715MC comes last in an overall list because its small 1/2.8-inch sensor is less versatile for wide deep-sky framing, not because its capture speed is weak. It reaches 45.1 fps over USB 3.0 and offers 8.46 MP resolution, 0.72-electron read noise, and 80% quantum efficiency. Those specifications make it the clearest pick here for a buyer who values rapid color capture and a compact sensor, especially for lunar or planetary work where collecting many frames can matter more than covering a wide field.
Compared with the ASI676MC, the ASI715MC offers the higher stated frame rate but a smaller sensor and rectangular rather than square resolution. The ASI676MC is a better match for all-sky recording and mosaics, while cooled models such as the SV605CC are more appropriate when long-exposure deep-sky imaging is the priority. This camera includes a 1.25-inch nosepiece, ST4 cable, protective cover, and a two-meter USB cable, helping with basic connection needs. It has no listed TEC cooling, so I would not rank it above the cooled models for faint-object exposures.
Pros:- 45.1 fps capture supports rapid collection of lunar and planetary frames.
- 8.46 MP color sensor offers substantial resolution for its compact format.
- USB 3.0 and included two-meter cable simplify connection to a capture computer.
- Includes a 1.25-inch nosepiece, ST4 cable, and protective cover.
Cons:- Small 1/2.8-inch sensor limits field of view compared with larger cameras.
- No cooling is listed, making it less suited to long-exposure deep-sky work.
- Its 12-bit ADC and small format provide a different role from the cooled deep-sky options.
Best for: Planetary and lunar imagers seeking a compact color camera with a high stated frame rate and supplied connection accessories.
Not ideal for: Wide-field deep-sky buyers, or anyone choosing primarily for cooling and a large sensor area.
- Sensor:1/2.8-inch IMX715 CMOS
- Resolution:3864 × 2192, 8.46 MP
- Pixel size:1.45 μm
- Frame rate:45.1 FPS
- Connectivity:USB 3.0
- ADC:12-bit
- Quantum efficiency:80%
- Read noise:0.72 e
Our verdict“I would choose the ASI715MC for fast lunar or planetary capture, but not as my first camera for broad deep-sky imaging.”
How We Picked
I ranked these cameras by the imaging problem each can solve, rather than by megapixel count alone. Sensor size and pixel scale influence framing and detail; cooling matters for longer deep-sky exposures; and frame rate is more useful for lunar, planetary, or transient capture than a large still-image resolution figure. I also weighed practical setup details such as USB transfer, buffer capacity, dew control, power needs, and the fit between a camera and the stated target types.
The product brief names the search topic as “askar cmos astro camera,” but the supplied models are ZWO and SVBONY cameras. I have not relabeled them as Askar products or assumed they are bundled with an Askar telescope. Compatibility depends on the telescope, focuser, adapters, mount, software, and imaging computer; buyers should check those details before choosing. The ranking favors a distinct use case for each camera and calls out where a competing model is the more sensible match.

| SVBONY SC571CC Cooled Color As | Dual-stage TEC, up to 35°C below ambient |
| ZWO ASI183MC-Pro 20.1 MP Coole | TEC cooling, 40–45°C below ambient |
| ZWO ASI676MC 12.6 MP CMOS Colo | — |
| SVBONY SV605CC Cooled Color As | Two-stage semiconductor cooling, up to 30°C below ambient |

Factors to Consider When Choosing Askar Cmos Astro Camera
I would choose an astronomy camera by matching its sensor and capture style to the target, then checking whether the telescope and mount can support the whole setup. A larger sensor is not automatically better if the optics cannot cover it, and a high frame rate is not a substitute for cooling during long exposures.
Start with the targets you want to capture
For faint deep-sky objects, cooling and a suitable long-exposure workflow matter, which puts the SC571CC, ASI183MC-Pro, and SV605CC ahead of the uncooled models. The SC571CC offers the largest stated sensor area, while the ASI183MC-Pro prioritizes small pixels and 20.1 MP. The SV605CC is a square 1-inch alternative, but its listed mass deserves attention. For fast-changing targets such as planets or the Moon, the ASI715MC’s 45.1 fps is a more relevant distinction. Meteor and all-sky capture point toward the square, fast ASI676MC.
Match sensor size and pixel scale to your optics
The sensor area controls how much sky fits in the frame, provided the telescope’s corrected image circle covers it. The SC571CC’s APS-C sensor covers more area than the SV605CC’s 1-inch sensor or the compact ASI715MC. Pixel size affects sampling: the ASI183MC-Pro has 2.4-micron pixels, while the SC571CC and SV605CC list 3.76-micron pixels. Whether finer pixels help depends on focal length, atmospheric conditions, and tracking accuracy. I would check a field-of-view or sampling calculator using the actual telescope before selecting by resolution alone.
Decide whether cooling is worth the added setup
TEC cooling supports longer deep-sky exposures by helping control sensor temperature and noise, but it adds power demands and setup complexity. The ASI183MC-Pro explicitly needs a separate 12 V, 3 A supply for its cooler. The SC571CC and SV605CC also use cooling, with performance stated relative to ambient temperature. The ASI676MC and ASI715MC are better suited to users prioritizing a simpler camera body, rapid capture, or monitoring over cooled long exposures. Cooling does not replace calibration frames or good acquisition practice.
Check frame rate, transfer, and computer workflow
A high frame rate helps collect more short exposures, especially for lunar and planetary imaging or transient events. The ASI715MC leads this group at 45.1 fps, followed by the ASI676MC at 31.2 fps; the ASI183MC-Pro lists 19 fps at full resolution. Actual capture performance can depend on settings, computer hardware, software, and connection. USB 3.0 appears across the supplied specifications, while the SC571CC’s 512 MB buffer is the largest listed. Check operating-system and capture-software support for the camera you choose.
Account for mounting, power, dew, and protection
Before ordering, I would verify focuser fit, back focus, payload, cables, power, and weather protection. The ASI183MC-Pro lists compatibility with 1.25-inch and 2-inch focusers and requires separate cooler power; the ASI715MC includes a 1.25-inch nosepiece and cables. The SC571CC’s window heater can help with dew, while the ASI676MC is not water resistant and needs protection for outdoor monitoring. The SV605CC’s listed 1.6 kg weight could be a deciding factor for a small mount or focuser. These are ZWO and SVBONY products, so verify any intended pairing with an Askar telescope rather than assuming a brand-matched package.
Frequently Asked Questions
Are any of these cameras made by Askar?
No. The five supplied products are from ZWO and SVBONY. I’m treating “Askar CMOS astro camera” as the search topic and comparing these cameras as alternatives; the listed information does not identify any of them as Askar-branded products or as an Askar bundle.
Which camera is the strongest choice for deep-sky imaging?
I rank the SVBONY SC571CC first for deep-sky use because it combines a 26 MP APS-C sensor, dual-stage cooling, a 16-bit ADC, and a dew-control window heater. The ZWO ASI183MC-Pro is a credible alternative if its 20.1 MP resolution and smaller pixels better suit your framing, while the SV605CC offers a cooled square sensor with less imaging area.
Which camera should I choose for lunar or planetary imaging?
The ZWO ASI715MC is the most direct fit if fast capture is your priority: its stated maximum is 45.1 fps. Its sensor is small, so it is less suited to wide-field framing than the square ASI676MC. Your telescope, atmospheric conditions, computer, and capture settings all affect how useful a frame rate is in practice.
Do all five cameras have cooling?
No. The ASI183MC-Pro, SC571CC, and SV605CC list TEC or semiconductor cooling. The supplied descriptions do not list cooling for the ASI676MC or ASI715MC. A cooled camera is more relevant for long-exposure deep-sky sessions; an uncooled model can make more sense for fast capture, all-sky monitoring, or a simpler setup.
Can I use these cameras with an Askar telescope?
Possibly, but compatibility cannot be assumed from the camera names alone. Check the telescope’s focuser and back-focus requirements, the camera’s connection and adapter needs, sensor coverage, mount payload, and operating software. Also plan for cooler power where required and suitable weather protection for an outdoor camera. Confirm the particular telescope and camera specifications before building a combined imaging setup.
Conclusion
My recommendation depends on the job. For a cooled deep-sky system with broad sensor coverage, I would start with the SVBONY SC571CC. For a detail-focused setup where smaller pixels and 20.1 MP matter more than APS-C area, the ZWO ASI183MC-Pro is the better match, provided its separate cooler power supply fits the plan. For a cooled square format, I would consider the SV605CC only after checking its listed weight against the mount and focuser.
For meteor recording or all-sky monitoring, the square-format ZWO ASI676MC is my specialist pick, with weather protection planned because it is not water resistant. For rapid lunar and planetary capture, I would choose the ZWO ASI715MC for its stated frame rate, while accepting its limited sensor area. These are ZWO and SVBONY options rather than Askar-branded cameras; buyers searching for an Askar match should verify optical and mechanical compatibility with the specific telescope.
