I tried to photo both M52 and the Bubble.  I don't have a go to mount so I use my setting circles on my C8 and my Nikon piggy backed on the tube.  I thought I pointed in the right direction using my 300mm telephoto.  I think I missed.  The first photo is what I got but it doesn't compare to one I'm trying to duplicate.  I know one can send a photo someplace and they will tell you what stars your looking at, but I can't remember the site.  Here's the first photo and then the second that I'm trying to duplicate.  Please help, I'm not having much luck searching star charts.bubble_rev3.jpg

Hi, I believe you have captured open cluster NGC 7789. It's in Cassiopaeia, a little over 6 degrees away from M52.

Given that this photo appears also in the DSLR forum, what medium was it taken on?

  It does looks like a film image, complete with the vignetting. Slide dupe? If scanned, looks like the upper end may have been cut. Too crunchy. My Epson scanner is in 16 bit mode and in "Professional" mode and the scanning parameters are set manually with each frame to be scanned. I leave plenty of pedestal on the clear base end and cap above the denser part of the negatives and slides. You got a 16 bit depth to play with on scarcely an 8 bit emulsion image. Pixinsight DBE is used in the 16 bit tiff to rid the vignetting, darkroom developing problems and the other natural sky gradients. I finish off in PS-6. 

  tuc, Good catch on the NGC 7789! I don't have that target yet. I have 755 viable finished pretty images in my spreadsheet going back to 1971. Some of the scanned film images are yet to be in that list. I'm going through and scan my old film images as a result of scanning family and the old star party images.

Here is a site that will help you identify what you took an image of.

It is always fun to see two deep sky objects of different kind in one photo.
