....... and last night I ran a second session to capture some OIII data. The conditions appeared pretty good but there was a lot of high altitude moisture around and I started off badly with some technical issues that I resolved and then had a flawless four hours. The net result was 24 x 600 sec subframes although I was surprised just how noisy these were, most probably because of the moisture.

This image combines the previous Ha mapped to red with the new OIII data mapped to blue with a synthetic 'green' channel. I have been a really naughty boy - NO calibration frames were used (or harmed) in the subsequent processing. I really do need to practice what I preach .........

That is stupendous. Like peering into the abyss... A window into another world....
