Just thought i'll bring this up as a point of discussion. Today, cooled CMOS Astro Cameras are available in plenty. QHY, ZWO and other variants of the same camera are selling for very reasonable prices. However, there was a point of time when astrophotographers used to cool down their DSLR's as a cheap OSC alternative to CCD cameras. Give a choice, I would've purchased a dedicated CMOS OSC which can cool to 40 C below ambient, but since I had a Canon 500D which I had self modded, I requested a friend Kaustav Chatterjee (an avid model railroader) to cold mod my 500D (he had cold modded his 1000D long back). This newly modded camera has a TEC12703 single peltier and cools to approximately 20 below ambient.What do you guys think?

This is 6 hours (30 x 12 min), taken with my modded Nikon D7000 @iso200 and Astronomik 12 nm Ha 2" filter on Meade LX200-ACF with reducer (=1600 mm FL @ F8). Guided with NexGuide on HEQ5 Pro.
The plan was to do a Ha O3 bicolour on this target, but the O3 may be a future thing due to weather conditions.
I usually remove the stars during part of my processing workflow and put them back later on, but this time I think the nebulosity and dust came out best without them. I did however try to find out which stars belong to Melotte 15 and include only those, just to portrait the Melotte 15 without anything between it and us, but I could not find that info.
Processed with DSS, Starnet and PS.
I bought my first telescope, SW 150pds about 6 months ago with the purpose of astroimaging "when i feel ready". So far ive used my Nikon D810 for that, and I'm now planning on taking the step buying my first AP camera.
My targets would be DSO's, and not planetary. I want a mono-camera, not color.
I want to get away with a very good camera to a reasonable price (wouldn't we all...) and in this regard I've been drooling on the ZWO ASI 1600MM Mono for some time. The price for it is in the upper part of my budget, but I'm willing to if its worth it. I've seen from other treads that sensor-size isn't everything, and dynamic range and gain and all is just as important, but i have trouble understanding it all 100% when it's all new to me, but in my experience i am a practical person who learns things much better and faster with the gear in my hand. So without getting to technical, and staying as objective as possible - please help me with;
1. Is this a good camera to go for?
2. It's sold with options of filters 1.25", 31mm or 36mm - Why these options, and what determines what i would choose?
3. Would you go for another camera in this price range, and why? - Or to rephrase it a bit; If you were in my shoes, which camera would you og for?
I'd appreciate any help:)
I might add, that i understand that with my lack of experience, buying a mono-camera with filters and all might seem premature, but for some strange reason. I enjoy these "way over my head"-projects and figuring out things as time goes - I just need some guiding in the right direction.
