M 106 Stil Prelim

Even though this is just short of 33 hours , I still consider it to be WIP

4 hours each R,G, 8 hours B in 10 min subs, 8 hours HII in 10 min subs, 4 hr 45 min L in 5 min subs

130mm f/7 TS apo, ASI 1600, Baader LRGB and Astrodon H-alpha filters encoder guided on ASA DDM60

Sigma Add stacking in AstroArt 7, H-alpha added to Red channel, and more processing steps than I care to think about, but DDP, Histo Stretch (Several times) Points Gradient Removal on each stack and final RGB, two rounds of Colour Curves. Luminance given DDP and Max Entropy Deconvolution before LRGB synthesis

I want another 4 hours ech Red and Green to balance the stack, plus Hydrogen (Maybe) and Luminance (Definitely).

C&C welcome as always.

Tha's very pretty.

A lovely pic Dave.

Thanks both

Despite 8 hours of H-alpha data the jets still aren't showing. Maybe I'll be able to use the possible clear nights next week to capture lots, as with the full moon I won't be able to do Red or Green, let alone Luminance.

What does the Ha you've got so far look like Dave?  They're quite weak compared to the general Ha in the core and inner arms

This is the H-alpha stack given some processing, Unfortunately the unstretched stack shows damn all hydrogen signal.

 

The middle image is what AstroArt was showing me using an auto-Auto stretch, the last image is the CCD range.
