A Great Foot from great skies

There's nothing like a holiday at new Moon to the superb skies near Coonabarabran ... and virtually no clouds in the sky all week! I spent one night basically just looking at the Milky Way . Obviously nobody in the Coona area bought new gear last week .

This is probably the best I'll do with my current equipment on the Lagoon, Trifid and NGC6559 complexes. Canon EOS 60D with 55-250mm lens at 250mm, mounted on an iOptron Skytracker, at f/7.1 and ISO640. A stack of 38 x 2-minute exposures, making my first >1-hour integration time. It's also my first foray into PixInsight, which seems pretty impressive software, though I did do a little fine-tuning and sharpening in Photoshop too as my PI kung fu wasn't quite up to the finishing touches!

Apart from the obvious familiar nebulae, I was interested to learn about a tiny red speck near the S-nebula B303 and NGC6559. Not an imaging artefact . The red speck is apparently M 1-41, according to detective work by Ray (Shiraz), and you can read lots more about that one on Ray's post (and a far superior image of it) from this time last year.

A larger version of the full image is in my gallery here.

Any comments, criticisms or tips are welcome!
