Hi Cloudy nights,
I have done some basic DSO imaging about 3 years ago and have waited to improve my processing/general astronomy knowledge, as well as waiting for a time when I have enough time and energy (now have more time as working less) to consider switching to DSO.
I have looked on this forum occasionally, and found a few images striking. For example, KathyAstro has done amazing DSO images including this:
I have a 150mm PDS Newtonian reflector (Skywatcher), but not had the chance to image with it much. I have HEQ5 PRo (quite new) and a 120mm-S guiding camera, ED70mm F6 refractor, some dSLR (1 H-alpha modified). I want to try for images like Kathy but cannot afford an ATIK 383L plus camera which costs about 2000 pounds , and the expensive RGB or narrowband filters.
1) What kind of CCD mono camera (cooled) can I get which is a bit less expensive (say sub 1000 pounds)?
2) Can I get basic filters which can give a reasonable result?
I really don't want to spend 10 years finding I cannot get anything like KathyAstro images.
Do you need to be in a dark site to get those or can you get them in Bortle 8 or 7 locations ? (I am imaging in the suburbs of Greater London).
Apologies if this has been discussed before, but I could not trawl through thousands of posts tonight...
