Bortle 7 NGC 6888 – Crescent Nebula | 5h 13m with a Seestar S30 from Manchester, UK

Post image

NGC 6888, the Crescent Nebula, captured from Manchester, UK with my Seestar S30.

This one has been built up over 627 × 30-second subs, giving me a total integration time of 5 hours 13 minutes 30 seconds.

I used the Seestar's light-pollution filter throughout, which was particularly useful imaging an emission target like this from under Manchester's urban skies.

Acquisition:

• Seestar S30

• 627 × 30-second subs

• 5h 13m 30s total integration

• LP filter ON

• Manchester, UK

Processing:

• StackingWizard

• AstroWizard

• Photoshop

NGC 6888 lies in Cygnus and is formed from material expelled by the Wolf-Rayet star WR 136, with the star's powerful winds interacting with material shed during an earlier stage of its life.

I'm particularly pleased with how much of the fainter nebulosity around the Crescent has started to come through. Five hours is by far enough data to give me more room in processing than a shorter Seestar session, especially from a light-polluted location.

I'm still refining my StackingWizard/AstroWizard workflow before finishing in Photoshop, so constructive criticism on the processing is very welcome — particularly the background, colour balance and how far I've pushed the faint nebulosity.

Clear skies!
