Nice resolution Scott. I think I prefer a more salmon pink and purple/red nebulosity to your more orange red though but nice work on a perenial favourite none the less dude
Thanks everyone
I should do a full hour on it and see what I get
This is the furst time ive used a more "gentle" filter, the LPS is only meant to block light pollution bands and let everything else through. It leaves emission nebulae less "monochromatic" then the more severe UHCS filter does.
To the monochrome CCD users, I wonder how you'd go using a LPS type filter for your Luminance shots particularily if shooting from light polluted areas?
