[Magnum]

Gamma Cygni Dark Nebula in Cygnus
3.5hrs in Ha with Atik 314L & Starwave 102 f7 ED.
Can you Spot the Impulse wake from the USS Enterprise? LOL ?

Update: On Saturday i was able to capture some Oiii data to compliment the previous Ha data and produce this finished Bi Colour image.
Total exposure now 8.5hrs comprising of.
21 x 10 mins Ha
17 x 15 mins Oiii
Atik 314L & Starwave 102 F7 ED.

Nice result, Lee.

I do like the colour image, but (this is no doubt a problem with me rather than the photo) I am struggling to see the change to the data produced by the Oiii - it looks to me like just a color version of the Ha image. Would it be possible to upload an image (maybe just a single sub) of just the Oiii data obtained?

Thanks.

Indeed a nice result. You've kept the black point high enough to avoid clipping the dark stuff, so it shows detail and variety.

Well the Oiii was quite faint on this one compared to the Ha so if i did it again I think I would increase the Oiii exposure to 20 mins, Ive pushed the Oiii data as far as I possibly can and am resonably happy with it. If it was just a colourised Ha channel it would be 1 single shade also the stars would all be that same colour. Here is a comparison of the Ha vs Oiii signal Only processing at this point was identical DDP stretch.

Thanks Olly

Thanks for the comparison shots. The OIII signal certainly is faint in comparison.
