The Bubble Nebula Project - Part II - Pre-Processing in PixInsight

Can't wait to watch the series. This is exactly what I am looking for. I want to figure out how to process the images so you can actually see the color and detail in the greenish/yellowish nebulous line in the skull's left cheek area. Right now, mine always comes out as pure white, with no detail Also, If you stack the images in Deep Sky Stacker, it will align the images for you. You just have to select a master reference frame in one of the tabs for the color channels, and just keep it as the reference frame as you stack each of the channels/tabs. So for example, if my reference frame is in the Ha tab, even when I stack the subs in the OIII tab, it will align them in accordance with the reference frame in the Ha tab, even though I am not including that sub in the OIII stack. Then when you import each channel into Pixinsight, you just need to crop out all the junk border areas. I've never taken the time to figure out the pixinsight stacking process, but I would think they would have a feature like that as well, to avoid the manual star alignment process.

Absolutely Brilliant Sir ... possibly the best explanation of the whole process I have seen ... Bravo

When do you get flats? And how? Why not to use Sharpcap master dark and master flat captures? It will do everything from start to finish for all filters in 5 min. Ready to use!

How do you select subframes without specifying image scale? It will not generate correct results.
