About this image

This is 6hrs of data. Split 4hrs L-eXtreme & 2hrs L-Pro filters, captured over 3 nights in Nov this year using an OSC camera.

The L-eXt was for the Nebula and the L-Pro for the stars.
It was discovered in August 1883 by the great Edward Emerson Barnard, bet he did realise it was the Pacman :)

Processing software:

Stacking in DSS then PixInsight using e.g. StarXTerminator, BlurXTerminator, NoiseXterminator – Pixelmath to combine Stars with Starless images... +Star reduction technique from Bill Blanshan {AnotherAstroChannel Youtube - watch Luke Newbould’s video on it (Lukomatico YouTube)}. Then a few tweaks in Photoshop & Topaz Denoise.

Clear skies all.
