You’ve picked up some of the dust at around 5o’clock which is good
Nicely captured.

I really haven't rung the data out on this as I didn't want to push my luck. Might redo it to see what I could do if pushed

Very nice Dave!
Love seeing Omega with some of the surrounding field like this. Great star colours too.

Thanks , pixinsight is a wonderful tool as I couldn't have got this without processing in that

It's really interesting to see some RASA data popping up on the web now.

Interesting times and an excellent result

Very humbling comment Peter, I have heaps to learn. 4hours on a target would be extremely nice. I still need to learn how to process the data but its hits and giggles at the moment . One thing I am not good with is the focus, the changes in temperature really affect the focus and autofocus is not a real option with the mirror locks. Somehow this little oversight needs a fix.

Very cool shot Dave.
Gotta love that RASA.

You are not Robinson Cursoe there. Focus was the main challenge I found using a mere F3.8 scope. F2.2 is a really tough gig.

Great result, love the pinpoint stars across the field.
Clear Skies Ken.

Looks good Houghy, did you have to do much gradient removal or were the dark skies of Duckadang kind to you in that department?

Just flats which I nailed this time

Cool, the benefits of truly dark skies, particularly if you image no lower than 35-45deg

A very good photo David.
So sharp...you seem to have the focusing under control.
F2.2.........so fast!
