IC 5070 Pelican Ha

Just playing around with some data I've been collecting for the HOYs project, struggling with LP gradients so not getting a good colour image yet but the Ha looks ok. 140mins from bortle 8/9 SE London, 8" f4.5, QSI583, Astronomik 6nm Ha.

Looks good Mark!

Are you satisfied with the 6nm ha filter in London or wish you had gone 3nm? I ask because I'm trying to decide between the two and live nearby!

Thanks Peds, I'm not very experienced with all this so not sure I can give you useful feedback- I chose the 6nm on cost haha plus i use the Astronomik deep sky RGB so it matches for focusing. It seems to work well for me though- I don't see any of the LP gradients I get on LRGB and only need dark/flat calibration (no background extraction) I suspect narrower would be better though?

Looks good to me, nice detail in the back of the pelican's neck.👍

This is the best I can get for colour-RGBHa. it's very red but its mainly Ha so I guess it is. Something funny going on with the bright star cores- probably from stretching too much, and the lp gradient I can't seem to get rid of. It looks better in B&W haha
