Great start with your new scope.

Thanks Doug! Yes, you are right! focusing was totally different to my f5 newt. It requires a lot more attention and seems to be a lot more temperature affected. I used a mask and had to focus twice during the session. But, I have a secondary dew heater so once I heated it up I turned down the heating a bit and it kept the temerature stable so I didnt have to refocus.
What really threw me though was my filter wheel! Half way through the imaging run a softward glitch made my filter wheel program restart. It threw out the sequence of the filters! I didnt realise until I processed the image and kept getting a green nebula! I reversed the LRGB combination and it came back to normal! So what was red was actually green!
i think its all worth it though as a faster scope makes it easier to get detail in a shorter time (allowing time to compensate for when things go wrong!)
