Peter, can I ask about your filters? Was this shot from light polluted city? Do you use LP filters? Or do you process out the LP with background calibration etc?

I'm located on the southern side of Sydney... light pollution is moderate to the south and tragic to the north.

LP filters are not useful with CCD's. I use a standard Baader RGB set.

CCD's behave quite differently to DSLR's as you have quite a bit more dynamic range, with significantly less noise. Hence it's not difficult to pluck usable signal from a good deal of light pollution.

Looks great now Peter. I did not think this was a quick and dirty. Forgive the critique.

Ho hum ... 15 minutes of data <yawn> ...

It's going to be clear tomorrow night and Saturday night. Let's see what 10 hours of data achieves!

Cheers, Marcus

PS: Just kidding Peter - I'm wiping the drool off my beard. A 12" APO it is!

Yes that's exactly what it is. I suspect Roland tweaked this 2nd run a bit from the first run. It seems even better.

They are sensitive beasties (to focus) Greg. I've finally given up on the hairy eyeball approach and ordered a Starlight digital focuser for the scope...hopefully will pull the star sizes in a tad more.
