If you live near the Sunshine Coast QLD you would have been frustrated with the hopeless conditions for imaging lately, clouds and bush fire smoke everywhere.
The Solution, I set up the scope and briefly through the clouds and bushfire smoke focused the camera on NGC 2070 then it clouded over for the next 5 hours so I decided to sneak up on the spider by setting the camera on auto taking 25 second subs all night while I went to sleep for the night. I was hoping that sometime through the night I would get some useful subs.
When I woke up in the morning I checked the 500 shots taken on the camera 420 were totally wasted but 80 were usable (this is one advantage of cloud dodging shorter subs), so a quick stack with no darks or flats and processing revealed this result.
80 X 25sec subs ISO1600 (33mins in total) No darks or flats
12” LX 200 (alt/az setup no guiding)
Sony Nex-3 Camera
I can only imagine what may have resulted if all 500 subs were useful, can’t wait for clear skies.
