Deneb-Sadr Region was created by Paul-Byrne

Hi all

On the night of the Perseids, 12-13 August, I set about imaging the region around Cygnus in H-Alpha.
The equipment used was a Canon 1100D astro modified camera, Canon 50mm f/1.8 operating at f/2.8, with an Astronomik 12nm H-Alpha CCD filter sitting on an iOpton Skyguider Pro.
I originally took 75 images, but somewhere along the way focus slipped and I was left with 14 useable images of one minute exposure each.
They were stacked in Deep Sky Stacker and processed in Photoshop.
This is the result:

There was one odd thing that occured, when I stacked the images a line appeared across the image about two-thirds of the way down.  I thought that it was due to Dee Sky Stacker, but when I stacked the in Sequator, the same thing happened.  I simply had to crop the image.
Has this happened to anyone before and how do I remove it if it occurs again?

Super image, Paul. 
NGC 7000 and the Pelican Nebula both look stunning!
All the other nebulas around Sadr look very good too. 

I'm sure you will get plenty of advice as to where you go from here. 

Very best regards from Aubrey.

Hi Paul,

Your image of the Deneb and Sadr region is fantastic... I really like it...you did a great job. Very well done. BTW that book you let me borrow is an excellent resource. Thanks again. 

Clear skies,

Hi Paul, a very nice detailed shot with the h-alpha ! The line you see is most likely a satellite trail, the sky is full of them now, more than ever before.

Thanks, Keith

The line I was referring to was when I stacked the images together, the line ran right across the stacked image, from left to right.  It ran just below the finished image, which was cropped to cut out the line.
