About this image

I just posted the L-eXtreme filter data only and here I have added the L-Pro to that L-eXt data. The bad weather over the past few months as allowed me time to practise my editing skills – the only positive about poor weather.

Subs details:

L-eXt, 300sec x 105 subs + 600sec x 4 subs, 9hrs 25mins captured over 4 nights

L-Pro, 120sec x 232 subs, 7hrs 44mins captured over 4 nights

Processing software:

Stacking in DSS then PixInsight (using e.g. BlurXterminator, NoiseXterminator, StarXterminator – Pixelmath to combine Starless L-Pro & L-eXt (Ha) together and then combine Stars (L-Pro) with Starless (HaRGB) image...

Clear skies all.
