Soooo, if I get a small chip astro cam like the cooled ASI178MC, will I be able to get more gooderer pics of tiny objects like this? Because I want em. They fascinate me. This thing is bizarre. |
Hi Kevin,
I used a DSLR for many years, and managed to get some great shots. Then one Christmas when it was hot, I noticed my Darks looked like Reds. I then added a cold finger to my DSLR, my Reds where back to being Darks.
What eventually convinced me to go to a CCD/CMOS, was trying to capture the Rosette and Helix Nebula, my camera didn't go far enough into the red (hydrogen alpha), so I couldn't get all the detail.
The big thing I noticed when I went from a DSLR to CCD camera, was the noise floor was so much lower, which meant that I didn't need work anywhere near as hard at processing the image. Noise floor becomes very important when you are dealing with heavy light pollution as I have too.
Now I see those little faint background galaxies appear in my shots which weren't there on my DSLR shots, I would never go back to a DSLR.
There is a little bit of a learning curve when you swap over, but it is well worth it in the end.
Just my thoughts on the subject.
Cheers
Peter
