I like the Veil, some very nice colours there and delicate wispy detail. I have found the Iris really tricky with the bright star in the middle, and Ha filters don't help as it is a reflection neb, so well done getting the nebulosity. What number and length of exposures did you use? Sounds like you used Photoshop to 'live' edit the image during the session?

Hi Rob,

   Thank you. No i edited the saved as viewed image afterwards. just the usual auto tone, contrast and colour with some basic levels and curves,etc    here is the saved as viewed image ( looked  better on the laptop at the time ?  ) 

Stack_30frames_258s.thumb.png.eb15d5425b79912b96ecb25d636e018f.png

i was doing 8.6 second exposures, the veil was 100 stacked and the iris 30 stacked.

 

here were my sharpcap settings for the iris, gain was a bit higher than i like as i had trouble stacking with a lower gain on this target. Yes i know i need a better dark to match my settings :)
