Finally had a clear night in Sydney last night. I managed a couple of shots before the wind picked up.
This is my first try at imaging a galaxy. I'm reasonably happy with it but looking forward to getting out again and trying to improve on it.
I've got a Astronomick CLS filter on order, so hopefully that will make a difference.
Both shot with my 6d and Celestron 9.25" SCT.
Southern Pinwheel Galaxy is 30 x 180sec.
Omega Centauri is 5 x 45sec + 2 x 90sec.
Looks good Murray. The only thing I can pick is that when enlarged
the stars look to be slightly elongated, so maybe 150 secs would have been better.

Thanks guys. Native focal length with a slight crop to remove the results of stacking and vignetting.
I agree that my tracking has to improve. I need to work on my polar alignment. Also been playing with the settings in PHD, which has improved things a little.
Hi Muzza, that M83 is awesome! The amount of detail you have resolved is amazing. I am jealous of the FL and scale of the images those cats give compared to the 600mm I have with my setup.
I think you should be as proud as punch to show that image off as your first galaxy. It's a quantum leap from my first galaxy and I still can't produce an M83 like the one you have for us here.
Well done!
Bruce.
Thanks Bruce and Rick.
I love the long focal length, but I'm struggling a little with my tracking. I think it all comes down to improving my polar alignment.
Hi Murray, I'm assuming that you are auto or manual guiding with a
scope of that focal length to get 180 sec subs, in which case your
polar alignment is not as critical as it is for people who work unguided,
like me. Your guiding should be more than capable of correcting moderate
polar misalignment. If you are working unguided, you are producing
a near miracle.

Thanks Raymo. Yes I'm autoguiding using PHD, Orion StarShoot and a 600mm guide scope. I'm pretty sure I should be able to do better than 180secs with that setup.
I'll keep playing. I'm sure I'll crack it eventually.
