I have a Canon EOS 1000d, which I modded back at the start of the year. I usually capture subs of about 3-5mins duration at ISO 800. However, I'm wanting to image the Deer Lick group with Stephan's Quintet, and I'm going to need to go right the way to 5 min subs for them.
I've noticed quite high noise levels at ISO 800, is this the optimal speed to use? Would it be better to capture subs at ISO 400, or would they then be really underexposed? Would I be better doing 3 min subs at ISO 1600?
I find ISO a little bit confusing, as far as I know it's a measure of how the camera's computer assigns brightness from the raw pixel values? 😐
Thanks for looking!
hello! yesterday i got my telescope, BRESSER solarix 76/350!
so yesterday i went outside around 9pm, I spotted Mars in the night sky very easily, I tried to aim my telescope towards it but... after like 10minutes, I still couldn't aim it ( I did choosed the ocular that had 40mm, biggest one I have ), then I gave up and decided to observe the core of the Andromeda Galaxy because it's way easier to aim at because of it's huge size..
Then huge clouds were coming and I decided to go back home with my telescope..
I did some research and there is a tool named "finderscope", but the problem is that my telescope doesnt have a rail or something that I can put a finderscope to, and im just asking if there is like a univseral finderscope or a finderscope that doesnt require to drill holes for screws, the only thing I observed yesterday was the sun( with my sun filter, I was pretty satisfied for a first time ) and the faint core of the Andromeda Galaxy/m31..
thanks for helping me!
Since a few days, I'm the proud owner of the asi1600 Pro.
Performed some first tests, see: https://youtu.be/hHJBbpNoi2I
I used SGP Pro to test cooling and dark frames (2m and 5m) on unity gain settings.
Is it ok to use unity gain (139) setting or should I use high dynamic range?
Also, this is my first mono. Do I need to take flats/bias frames for each filter separately?
And how could I stack either broadband or narrowband images? I'm used to deep sky stacker.
I am associated with a college who had purchased a Celestron EDGE HD14 two years ago. Due to the high humidity of the place, there has been quite a bit of fungus which has grown on both the front corretor plate and the rear coma corrector lens which is inbuilt into the central hole. If anyone would know how to disassemble the EDGE HD 14 from the front and rear end it would be very beneficial.
