Please add comments to the tutorial described in the NGC6888 Ha Tutorial
Hei and thank’s D. Fielder. The NGC 6888 is a difficult object to preprocesd. It is very easy to «burn» the edges. It is quite a job to make a good tutorial so I dont think I will make one for bicolor. My tips is to spend time to create masks to get the blue stretch, and be carefule with the colors. There are a lot of very good images that from my point of view is fare to blue. Please send a link to your image(s)
Hello Erik,Just found your website and blog - absolutely stunning images and an inspiration to beginners like me who have just started a couple of years ago astroimaging. A couple of months ago, I've started narrrowband imaging and bought PI. While a steep learning curve, it really provides very specific processing steps resulting in a great image.I've just completed imaging the Crescent Nebula and like your Ha tutorial. Very imformative! Do you plan to do one for the bicolour or HaLRGB? I tried to do an HOO image, but my reds turn magenta when I try to increase the OIII blues in the nebula. You seemed to have mastered this very well. Thank you again posting your images. D. Fielder.
