The Whirling Dervish Nebula

Its NGC 3247-to the best of my knowledge -and as far as Google can see -no one has imaged this object-certainly no amateur image that I can find; catalogues list NGC 3247 as a galactic open cluster, some say with associated nebulosity....well certainly a lot of nebulosity!

so may I claim the right to name this nebula-the whirling dervish nebula. Do you see why?

as an image its not really good. Had problems with the polar alignment in the H alpha so had oval stars; the camera must have slipped somehow when taking the RGB, had coma which I never normally get with this telescope. Did what I could in processing but it hurts the final result of course.

So this is a place holder for when I can go back and it properly. But its kinda cool to share something that as far as I can see no one else has imaged, even if its not the greatest picture
details:
telescope ED 127
camera QHY8
mount EQ6
Filter (for H alpha) Baader 7 NM

3 hours (9 x 20 minutes) for H alpha
1.5 hours (18 x5 minutes) for RGB
combined using nebulosity to align

here's the larger version:

thanks for looking
