Description

I was hoping to get enough subs for this in time for the 100th anniversary of the RAF on the 10th July. A cloudy night put paid to that, so a day late here's the propeller nebula DWB-111 in a blend of 60/40 Ha/SII in the red channel, 85/15 OIII/Ha in the green and OIII in the blue channel.

B

A stretched and LHE sharpened image blended with Rev A. Will add to this if the clouds forecast don't appear.

C

Thought I'd have another go at tone mapping.

D

Same tone mapped stacks but un-linked the channels before stretching them. Don't need the sunglasses this way.
