The ASI1533 ISC Camera maybe more suited for planetary imaging at only 9 megapixel and it has a very small sensor size
If you want to image DSO’s the following cameras maybe more suitable -
ASI1294MC sensor size 19mm x 13mm Resolution 11.7 megapixel Pixel size 4.63uM
ASI 071MC sensor size 23mm x 15mm Resolution 16 megapixel Pixel size 4.78uM
Both these cameras will achieve sampling rates of around 0.90 arc sec per pixel at your focal length of 1000mm ie: slightly over sampled
The ASI183MC is another option but at a pixel size of only 2.4uM you would be way over sampled at your focal length of 1000mm ( not a wise option, more suited to a shorter focal length telescope )
Choices , choices but in the end it’s what you can afford
In the end for DSO imaging some of the specs to look for is a pixel size to get you slightly over sampled for your focal length 0.80 to 1.20 arc sec per pixel , medium to large size sensor , high ADC bit say 14bit or 16bit and a high QE 80% or higher
Hope some others can chime in who know a lot more than me about dedicated Astro cooled OSC cameras
Good Luck

Thanks Martin yet again!
Deep sky objects is my aim and hopefully my outcome. At the moment I'm using a QHY8L with a 7.8uM and seems to match my scope well? I was just after an upgrade, newer technology, more MPs etc. So confusing, but its all starting to come together, I think it was the Bintel email that has thrown me or woke me up to the fact that there's more than just picking a camera and away you go, the valued answers in this post has certainly opened my eyes big time.
At a 1000mm F/L my imaging scope is proving a little bit on the tricky side to make this the right choice to get it right and what you have added has made it more clearer and I thank you for that.
I will look at the ASI1294MC and read up a bit more on the reviews and look at some of the images this camera is taking, it will give me some indication on its performance and hopefully find someone with a setup close to mine. Who knows my prime imaging scope may change and it may be better suited to the newer one with a shorter F/L.
Many thanks Martin!
