The First CMOS Astro Camera with Adopts Sony IMX410 Sensor!
ZWO has designed a camera that gives high quailty performance through large well capacity, low read-noise, and high dynamic range the ZWO 2400MC Pro is another great innovation of ZWO in the field of full-frame astro cameras! Whether you refer to it as the ZWO ASI2400, ASI2400MC Pro, or by its product code ASI2400MC-P, this model stands out as a flagship option in ZWO’s colour camera range.
The ASI 2400MC Pro features a full-frame 36mm x 24mm Sony IMX410 sensor with a 43.3mm diagonal and 5.94μm pixel size, resulting in a total resolution of 24MP (6072 x 4042). This large sensor captures expansive fields of view, making it ideal for imaging wide deep-sky objects and mosaics with fewer panels. The 2400MC Pro camera’s USB 3.0 interface and 512MB DDR3 buffer ensure fast and reliable image transfer, reducing the chance of frame loss during long exposures.
The ZWO ASI 2400MC Pro features a two-stage TEC cooling system, capable of achieving ΔT of 35°C below ambient temperature, helping to minimise thermal noise during long imaging sessions. Its design includes an IR-cut protective window to block unwanted infrared light in standard broadband imaging applications.
Camera Performance
With a full well capacity of 100,000e⁻ and 14-bit ADC, the ZWO ASI2400MC Pro offers a dynamic range of up to 14 stops. At a gain setting of 140, HCG (High Conversion Gain) mode is activated, significantly reducing read noise down to just 1.1e⁻, while retaining high dynamic range. This allows astrophotographers to capture rich tonal detail and avoid overexposure in bright areas like star cores or nebula highlights.

Quick Guide | 1 |
Q1. What is the standard backfocus distance for the ZWO ASI2400MC Pro?
The ZWO ASI2400MC Pro (also known as ASI2400, ASI2400MC-P, or ZWO-ASI2400MC-P) has a standard backfocus requirement of 55mm, which is optimal for most flatteners and field correctors. Always confirm the required spacing with your telescope’s reducer or flattener documentation.
Q2. How do I reach 55mm backfocus with the ASI2400MC Pro?
Start with the 17.5mm sensor-to-flange distance on the ASI2400MC Pro, then add spacers and accessories to reach 55mm total. For example: 17.5mm (camera), 21mm (M54 extension ring or filter drawer), 16.5mm (16.5mm M54-M48 adapter or OAG). This gives a total of 55mm.
Q3. How do I calculate backfocus when using a ZWO filter wheel?
When using a ZWO Electronic Filter Wheel (EFW) with the 2400mc, such as the 7-position 2" EFW or 7x36mm, they typically add 20–21mm of backfocus.
For a typical setup: 17.5mm (ASI2400MC-P camera), 20mm (EFW electronic filter wheel), 16.5mm (M54-M48 extension or adapter) for a Total = 54–55mm.
Q4. How do I calculate backfocus when adding a ZWO Off-Axis Guider (OAG) with the ASI2400MC Pro?
The ZWO OAG adds about 16.5mm of backfocus. A sample setup might look like: 17.5mm (ASI2400MC Pro) + 16.5mm (OAG) +21mm (M54 extension ring or filter drawer) Total = 55mm.
Note: The OAG prism needs to be aligned with the sensor for proper guiding.
Q5. Do filters affect the backfocus distance with the ASI2400MC Pro?
Yes, filters, especially in a filter drawer or wheel, shift focus slightly—typically 1/3 the thickness of the filter. For a 2mm thick filter, this means reducing the backfocus by about 0.66mm. ZWO already accounts for this in their 55mm recommendation, assuming standard filters are used.
Q6. What if my stars look distorted at the edges—could it be a backfocus issue with the 2400MC Pro?
Yes, coma, elongated stars, or blurry edges are common signs of incorrect backfocus. Double-check each spacer’s thickness, make sure components are properly threaded, and measure the total optical path to ensure it equals the required backfocus.
Q8. What software is compatible with the ZWO ASI2400MC Pro?
The ZWO ASI2400MC-P is compatible with a wide range of astrophotography software. You can use:
ZWO ASIAIR for a mobile-friendly, all-in-one imaging solution (requires ASIAIR Plus sold separtely), ZWO’s native Windows/Mac drivers with ASIStudio, third-party software such as NINA, SharpCap, APT, Sequence Generator Pro, and FireCapture, using ZWO’s ASCOM and native SDK drivers.
Make sure your software is updated to the latest version to ensure full support for this full-frame camera.
Q9. Can I control the ASI2400MC Pro using ASIAIR?
Yes, the ZWO 2400MC Pro is fully supported by ASIAIR. You can control cooling, gain, offset, exposures, and filter wheels through the ASIAIR app. Keep your firmware and app updated for best performance.
Q10. What gain and offset settings are recommended for the ZWO ASI2400MC Pro?
This varies by target and sky conditions, but ZWO recommends:
Gain 100 for optimal dynamic range and low read noise
Gain 0 for maximum dynamic range in bright targets or longer exposures
Offset typically ranges from 30–50 but should be adjusted depending on your software and histogram.
Q11. Can I use DSLR lenses with the ASI2400MC Pro?
Yes, you can use DSLR lenses with the ZWO ASI2400MC Pro by adding the appropriate lens adapter (e.g., M54 to Canon EF or Nikon F). Ensure you maintain the correct 55mm backfocus and note that you may require a manual aperture ring or electronic controller depending on your lens.
Q12. My software doesn't recognise my ASI2400MC Pro camera – what should I do?
Try the following:
- Install the latest ZWO native and ASCOM drivers.
- Check your USB 3.0 cable and port; use a powered hub if needed.
- Test connectivity with an alternative app like ASIStudio.
- Update your software or firmware (e.g. ASIAIR, NINA).
