M83 and M16 revisited

[Benjamin (Ben)]

Thanks Raymo for encouraging me to keep at the 8" Newt on the HEQ Pro! I finally got out again and decided to tweak my PHD guiding (more aggressive corrections and a faster exposure rate on the guide cam) which really seemed to help. PEC training is probably next but as I dither between frames I'm not quite sure how to go about this yet. Some reading to do.

I started with a fast sinking M83 (10x 5 minute subs) and got some terrible gradients (moon, LP?) but some aggressive gradient removal got rid of most of it. Lots of noise and and a blue background. Got something that kind of looks okay form a distance!

Also revisited M16 (20x 5minute subs) and had similar gardients but lots more signal. Was happy with the data but processing needs more time to balance detail and the outer reaches of the nebula. Attached a cropped close up (less stretched) and a wider view (with more stetching but a little flat looking and a residual blue gradient....)

pretty good ben, i like the 1st eagle the most, its pretty sharp and well balanced. good work.

cheers

Ben, you'd be better off concentrating on one target per night, and
getting as many subs as you can. A large number of subs will reduce the
noise substantially.

Yep. Would loved to have more time on M83 in particular but it's only above my roof and tree for a shortish duration (last subs were all tree!). I've been keeping my light frames so at least I can start to build on that :-)
