Thanks Jim, yes I think I will call it a day on this one. It is quite a commitment on imaging time, which always seems to be at a premium here in the UK.
My project for the Winter was to capture this area of dark nebulae in the constellation of Camelopardalis. I have imaged this before, but this time I wanted to include OIII data in an attempt to reveal the Thor’s Lightening (the blue colour in the image). The OIII signal is very faint, so I knew...
This is from from some old data I had from 2022; just over an hours worth (25x150s)
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.
