M8, M16, M20 and M83 - ST9 + RC

Last night was amazingly clear and dew free here in brisbane. I took advantage of this situation and invited Robin (Tandum) over for a night of imaging...

I managed to get these four images which are a damn sight better than last weeks efforts with this scope.. Collimation looks a lot better, as does the focus.. I definitely think there is more in it however!

M8 - 60x1min @ 13nm Ha
M16 - 80x1min @ 13nm Ha
M20 - 40x1min
M83 - 33x1min

The M83 image looks a little strange, It was the first image for the night and it was after this image that I pulled my desicant cap out and stuck it in the oven, and replaced it with my refillable unit from PWT. After this the resulting images were a lot sharper...

One thing is for sure, I need a bahtinov mask for my RC.. After using Robin's one I realised that my initial focus was always out by a whisker or two.. So I think fixing that is the way to go!!

Thanks for looking... Oh, the other pics are shots of our setups all ready for the night...
