M83 + DSI II + Guiding +full moon

I finally got my autoguiding working last night. Despite the full moon I had a go at some long DSI II exposures (26x2 min subs) through the ED80. I'm quite pleased with the result and wished I'd got the autoguiding a lot earlier.

That's really nice, Peter! Autoguiding really does make such a huge difference, you wonder why you didn't bite the bullet and do it earlier.

Are you doing flats and darks, too?

Will you be going RGB or H-alpha down the track with your mono DSI II?

Hi Peter

That looks very good, especially for a full Moon nearby. And yes, auto guiding is sweet once you have got it up and running. All you need now is a permanent observatory!

Cheers

Dennis

Is that using the 102mm guidescope? Hope its working for you - and by the way a great shot!
I'm still in Cambodia/Vietnam - storms and torrential rain makes even getting out at night to see any stars a chore. Hope I don't bring it to astrofest with me. Have a good time there and I'm looking forward to seeing you there.

Thanks everyone for the comments. Mike I'm doing automatic dark subtraction in Envisage but no flats yet. I started on the RGB last night on M20 but had some frustration with the goto so wasted a lot of time and my poor west horizon beat me in the end.

Dennis - no need to encourage me - perhaps you can help me convince my family - I'm competing with a garden bed and a soccer field as alternative uses for the site.

Allan - yes I had your 102 guidescope side by side with my ED80. It's taking a bit of time to get used to finding a guide star and I've ended up using PHD as it allows me to use the long exposure mode of this guide camera (althought I still prefer the feedback guidemaster provides).

The weather in Brisbane has been magnificant the last few days - hope it persists for Astrofest.

Peter.

Way better than my attempts on this subject with my Pro II. Exposure time is king on galaxies. Nice detail in the arms

Very Nice Peter, Auto guiding makes a world of difference when you extend the time of the exposures. A lot of detail in this shot. Well done.
