Despite the nearly full bright moon I got out last night and managed to save 7, five minute exposures (satellites and planes)

I am still new to DSO processing so this has been shrunk down as it was processed a little too hard. Its still a little too light as well.

 

I'm also still trying to find out the best method for setup each night. Here, I set the mount up, polar align with scope and sync a few stars to make goto's more accurate. Once I land on my object, I ensure its centered then launch PHD2 to start guiding.

 

Takahashi FC-100DZ at F/5.3.

ASI 2600MC

35 minutes total exposure time.

Good job

Thanks for all the likes and to be sure I didnt mislead anyone, this is not my first attempt. That said, I dont have much experience with it. Just dabbling here and there and its been a while since I did that. The processing was done via ASI Stacker and I took that TIF file and loaded it in Gimp. From there is was all curves.

It's better than I've done, so far, on M31. (Its size is a poor match for my equipment and I'm not up to mosaics yet.)

 

Don't forget to load flats when you stack, looks like that might help.

Thank you. I did load flats, bias, and darks. That said, the flats were just a t-shirt flat with an ipad lighting things in front. So Im sure they could be better. I also only got 4 dark frames and I should have had around 15-20 from what i read. Ran out of time last night.

 

What is the best way to get good flats?

I love it.

 

The bottom 20% or so looks a little funky but the rest is wonderful to look at.

I can't believe that's only 35 minutes.  Well done.

5 min exposures is no joke, your polar alignment must've been excellent.

Thank you Mike,

 

Yup 7, five minute files (lights). Where I live is around bortle 5 but the moon was bright last night. I have a farm about 30 minutes from where I live and its bortle 3 so I need to get out that way for a night.

 

For the polar alignment, well, I was fortunate enough to get on the list for an 1100GTO earlier this year. I used the RAPAS and it is so nice to use. I took their word that it is pre-aligned b/c I have not done anything to it other than pop it in, adjust, then remove it.
