Messier 16 in LRGB (processed with P Plates!)

Hello,

Well, it has been a long time coming so here is my 1st proper LRGB with the ST7E and CFW8, that have lain dormant for donkey’s years! I have much to learn about this process but I can report that I kind of enjoyed having a go at M16, chosen for its intrinsic brightness and having a good guide star nearby.

L=20x3mins (60 mins total)
R=5x3mins (15 mins total)
G=5x3mins (15 mins total)
B=5x3mins (15 mins total)

Sub-frames were Reduced (Darks & Flats), Aligned and Combined in MIRA AP.
Final LRGB in CS3 but goodness knows how, as I probably can’t repeat the trial and error process after much faffing around; I must get a good book and take notes!

Suburban Brisbane, 23rd August 2008, Tak Mewlon 180mm F12 with Reducer/Flattener at F9.6, auto guided using the ST7E TC211 guide chip. Some of the sub-frames were softened by thin clouds popping up from seemingly nowhere.

Cheers

Dennis
