cooled osc camera for around 1000.-

[serene glen]

I would like to buy my first cooled astro-cam, due to the fact that my dslr recently „broke“ (I destroyed it). Can you recommend any cameras in my price range?
I already noticed the zwo asi533mc and the asi294mc.

533 will be better than the 294. Often the 294 is a camera good only under very specific circumstances, the sensor technology is older than the 533, and it costs more

what about the explore scientific deep sky 16mp color? specs wise it seems kinda great

what specific circumstances? I am also looking into getting my first osc (likely buying used though) so would be interested

I am new to this but from my research you'll want to keep in mind the arcseconds per pixel resolution

https://www.bintel.com.au/tools/astronomy-calculator/ can chuck in the data here, ideal resolution is: 0.67" - 2" arcseconds per pixel

Personally I am very happy with my 533mm(mono but same sensor as osc) so far, I did my research, and that specific circumstances is when you need a bigger fov, but I personally find square fov fine on a lot of target, and also there has been a lot of comments on the calibration frames on 294, 533 has very low read noise, no amp glow, and newer sensor tech, so overall better unless fov is one of your consideration

[junior mica]

thanks for the reply, yeah not having to deal with amp glow would be really nice but I have heard its easy/quick to do once you know how to do it but still something worth considering

[charred rapids]

that is often said, but people ignore a big problem, the part that has the amp glow has significantly less signal compare to the rest of the image

the only reason in this case to go for a 294 is for a rectangular fov

533 is suprior in all other aspect, and experimentating myself I find rectangle is actually quite good
