Enjoyed

I know your scope is well tuned but you do seem to get some good seeing...lucky bugger

Mike
thanks very much Mike - very generous. The seeing has been good at times, but the biggest thing was building an ROR obs. I can now use an aircon to get the scope surrounds quite cool during the day and that has improved local seeing by maybe 1/2 an arcsecond over what I used to get.

thank you Adrian. I agree, it really is a beautiful object.

Hi Josh. thanks for the kind comments. M104 was 7.5 Lum, 6 RGB and M20 was 3.3 Lum and 3.7 RGB. all 1x1 @ 3 minute subs (3 minutes is about optimum for L with this system under my typical sky, but I also use that for colour to improve stars even though not optimum). There is still a bit of noise in the background, but its not too bad.

Are those lots of globular clusters around the galaxy itself?
the mount is not perfect, but it does well enough with some coaxing. Yes, those are globs - Rolf went to the trouble of identifying them in his image at http://www.pbase.com/rolfolsen/image/143968106/original

Thanks very much Geoff. It took a fair bit of time to get reasonable data - I had to discard frames with poor seeing, so a lot of bits ended up on the cutting room floor.
