Buy it if
- You want a cooled APS-C mono camera for narrowband and already own a filter wheel and filters
- You want the IMX571 mono sensor for less than ZWO charges for it
- Your telescope has an APS-C image circle, like a small Petzval or a 60 to 100 mm refractor
Skip it if
- You are starting out: a colour camera needs no filter wheel and no filters
- You have few clear nights: one colour image from mono takes several filtered runs
- Your astrograph covers full frame and you want the widest field it can give

73/100 Stars for Your Buck
Pros
- The Sony IMX571 mono sensor: 25.9 megapixels of 3.76 micron pixels on APS-C, with a native 16-bit ADC.
- In one August night it gave me four nebulae in S, H and O, 3 h 48 min of subs in all.
- Two-stage cooling rated at 35 C below ambient on short exposures and 42 C on long ones.
- Less than the same sensor from ZWO: £1,488 at Dark Clear Skies against £2,059 for the ASI2600MM P25 at First Light Optics.
- Zero amp glow and a 512 MB buffer, according to ToupTek.
Cons
- Mono needs a filter wheel and a set of filters before it makes a colour image.
- A colour image means several filtered runs: my four targets shared one night at 42 to 87 minutes each.
- First Light Optics does not stock it; in the UK it comes from Dark Clear Skies.
The IMX571 mono sensor in a cooled ToupTek body for less than ZWO charges, if you are ready for a filter wheel and several filtered runs per image.
Who the ATR2600MM is for
Narrowband imager with an APS-C refractor
Buy
The IMX571 mono sensor suits an APS-C image circle, and on my SQA55 it framed the whole Veil loop in one field.
Complete beginner
Skip
Start with a colour camera: mono needs a filter wheel, filters and more clear nights.
ZWO ASI2600MM owner
Skip
Do not switch: it is the same sensor with the same 3.76 micron pixels.
Budget-conscious mono imager
Buy
It costs less than ZWO's ASI2600MM Pro for the same IMX571 mono sensor.
Imager with a full-frame astrograph
Skip
The ZWO ASI6200MM Pro fills a full-frame field; this sensor covers APS-C.
Imager who wants colour first
Skip
The ToupTek ATR2600C is the colour twin of this camera and needs no filter wheel.

- Is the ToupTek ATR2600MM worth it? For narrowband on an APS-C telescope it gives you the IMX571 mono sensor for less than ZWO's version. It is not a first camera: mono needs a filter wheel and filters. The specifications and the comparison table ↓
- Is the ATR2600MM the same camera as the ATR2600M? Yes. ToupTek sells it as the ATR2600M (part number ATR3CMOS26000KMA), the mono twin of the colour ATR2600C. The specifications and the comparison table ↓
- What did I capture with it? Four nebulae through the Askar SQA55 in one August night: the North America, the Veil, the Elephant's Trunk and the Heart and Soul, 14 to 29 subs of 180 s each in S, H and O. What I captured ↓
- How cold does it run? ToupTek rates the cooling at 35 C below ambient on short exposures and 42 C on long ones. I run cooled cameras at a -10 C set point; my stack headers do not record the temperature. Tested numbers and the download ↓
- What back focus does it need? 17.5 mm from the sensor with the M42 adapter, or 12.5 mm with the thinner adapter in the box; ToupTek's filter wheel and extenders make up the usual 55 mm. The specifications and the comparison table ↓
- How much does the ATR2600MM cost and where can I buy it? The prices I recorded: £1,488 at Dark Clear Skies (UK), in stock; $1,899 at Agena Astro (US), in stock; $1,899 at ToupTek Astro (Global), in stock. A record, not a live price The verdict, the readers and the sellers ↓
- What have I not tested on the ATR2600MM? LRGB imaging, guiding, and ToupTek's read noise and full well figures: not tested.
