Corona Australis region

[cometcatcher]

The Corona Australis Molecular Cloud, a dark molecular cloud with many embedded reflection nebulae, including NGC 6729, NGC 6726–7, and IC 4812. A star-forming region of around 7000 M☉,it contains Herbig–Haro objects (protostars) and some very young stars. About 430 light years (130 parsecs) away, it is one of the closest star-forming regions to the Solar System.

GSO 10" F4 Newtonian, ZWO ASI 183mm Pro cooled to -10C, Red 508 x 30 seconds, Green 426 x 30 seconds, Blue 452 x 30 seconds, total 1386 x 30 seconds or about 11.6 hours and it's still screaming for more. I wasted 2 nights with poor framing. The observatory wet with dew after every session.

Great shot Kevin. :thumbsup: It's an amazingly complex part of the sky. So much happening there. Coincidentally I'm in the middle of trying to capture the same thing. Only time for a few reds and greens last night before the clouds came. Maybe tonight...

Thanks Kevin. Hope the sky is good for you. We had 5 nights clear in a row. First time this year!

A great looking photo Kevin.


I love the colours.


You've got your new equipment working so well.


Ross.

Thanks Glen and Ross. I haven't had much time to use it though for cloud. I need more practice.

Awesome work Kevin, some incredible detail there.
Cheers,:thumbsup:

Great job & a nice result Kevin.:thumbsup:
I’m curious though, as to why you take zillions of 30 sec subs, instead of 20% as many longer, say 5 min subs?
Cheers
Andy

That's a sensational image.

Thanks all!




A rather late reply Andy, but it all started when I was shooting DSLR without guiding. With a fast scope the concept works well.

SO with shorter subs I can

Sometimes dispense with guiding.
Get less flex from the guidescope when I am guiding.
30s can shoot in cloud gaps that longer subs can't.
Less satellite trails.
Bad subs easily deleted without much loss.

There's likely other reasons I forgot about.

Alrighty then, makes sense :) - I like the idea of shooting through cloud gaps! :thumbsup:
