This is 3 hours of Ha on the Cresent neb. I hadn't realised how much dust surrounded the Nebula. The image ended up a little noisy, not sure if I missed something in the processing or if it's due to it's low angle in the northern sky.
20 x 10min subs in Ha with the Moravian G2-8300 and W.O FLT 110 and reducer.
Comments and suggestions welcome

Beautiful image Geoff. I'm going to have a crack at the one I took at astrofest to see how the Ha goes by itself. My coloured one is a little dodgy. Well done.

Thanks Guys, I even surprised myself with this one:D.
I might try for some colour data next new moon night and try some LRGB + HA blending...that might be fun:P

Wow, that's amazing Geoff. I didn't know it could even be imaged from Oz.
It doesn't look noisy from that size image.
A beauty.
Are you going to shoot colour?
If you have an O111 filter this one looks great in bicolour -Ha/O111.

Thanks Greg, appreciate your feedback.
I only have RGB filters ATM, however I do have 1hour of each RGB captured at Astrofest. I hope to grab some more data at a dark site on the next new moon. Being low I want to give the image as much data as possible. Then I'll try out some HaRGB blending, that should be fun:P
Cheers

Sounds good. If you need a hand with the HaRGB blend just yell out.
Greg.
Wonderful Geoff. I didn't realise it drifted into our sights here in Brissy either. Congrats on a great image :thumbsup:
Lovely work Geoff. I'd imagine this would be quite low so I'm amazed at how well you've captured the scene. A very tidy image. Would be great to see colour added. You sure have plenty of Ha data to progress with. Looking forward to seeing more.

Thanks Greg for the offer, I'm sure I'll be in touch
Thanks Rob, I hope to grab the colour data at 10CH this new moon, fingers crossed
Jase, thanks for the kind comments,it is low, max alt is 24deg as it crosses the meridian.
Cheers Geoff

Well done mate! I wouldn't have thought it possible from home, but you've proven it is worth having a crack at.
