First post on Astrobin hope it works ok!
Target was NGC7654 , but caught The Bubble Nebula and Star 4CAS,
ISO800.
21 x 180 Seconds Subs.
Taken on 18/06/2017.
Stacked with Astro Pixel Processor  No Darks No Flats No Bias.
Processed with Photoshop and Faststone Viewer.
I`m aware of the bright area around NGC7654 but if i clear this it makes the Bubble Nebula hardly noticable.

Stars are nice and round, I guess you weren't intending to capture a DSO and thus the 180 sec subs.  However if you want to get a DS object you really need 5 min subs. 

Also why no calibration frames?

The black background is too clipped but otherwise a good image.  Summer's not over and you have Autumn and Winter to look forward too.  Let's hope it's a good one!

I am going to give Roger a processing session at the next DSC, but he'll have to bring some data with him to process.  It's all leaning that we probably all went through at the beginning, but as Fay says you are doing well, Rome wasn't built in a day.

QuoteThe black background is too clipped
Mark is right, another thing to avoid.  Don't be tempted to make the sky too black.

Roger, have you got Photoshop, or I will be sunk without it?

I don't do Pixinsight and I tried GIMP while I was on holiday as I didn't have PS on my mini laptop and could not get it to do anything useful.
