Description

Exploring some familiar targets at longer focal length here with my Meade 12in F8 ACF with 0.67x reducer making around 1700mm at ~f5.5 - a good focal length to fill the m43 (ASI294mm) frame with the Trifid Nebula.

This was taken over a few nights in the early evening before I moved on to galaxies.

L using 45s exposures
RGB using 90s expsoures 

As per my usual indecisive approach :-) stacked and processed in APP and saved out as both LRGB Tif and separate channels that I then combined and processed in startools to another TIF result. Into PS CC with both outputs, aligned and used starXterminator to produce starless layers that I blend and further process and picking the best stars to recombine at the end.
