Camera: ASI2600MC
Telescope: Esprit 100ED
Processed in Pixinsight and Photoshop

Great info Mike, I will certainly try adding the formula into my current imaging spreadsheet. I checked my bookshelf, I don't have the Sky Atlas but do have Charles Bracken's book 'The Deep Sky Imaging Primer'; it contains a wealth of information on image acquisition, processing, and image...
This is a re-working of NGC6820-6823, using a hybrid workflow in Pixinsight and Photoshop.
Shot in SHO using my Esprit 100ED and the ASI1600MM camera.
SII: 39 x 150s
Ha: 110 x 150s
OIII: 43 x 150s
Stars were SHO converted to RGB using Seti Astro’s NB to RGB star combination script.

Hi there, firstly I would say, try not to make the mosaic frame any larger than you need to, so that you are not spending imaging time on areas of sky you might well crop out anyway. Also, I do tend to stick to 10s exposures on mosaics, as that way you get the full field of view covered in less...
That's a great rendition, all that data and perseverance certainly paid off! You have managed to get a great feeling of depth and love the colours. I've always liked this target both with and without stars. Great job.
There is an issue with Uploading Photos (attachjments). I am not sure what the problem is, and I am looking into it. You can still try to Create your Threads and Upload your Photos, but it is hanging up during the Upload.
