Marc, Thanks, I think that by only using 50% of all the frames, its dropped out all the frames where the dew had formed on the secondary..
Here it is again, Darks and Bias frames applied... Not bad for 30mins data I think...
Trevor - Yeah, it is too red, but essentially, that was just a mess around just to see what the false colour tool did... I did nothing to it to correctly balance the colour, just thought I'd post it for laughs...
In any case, I HAVE to sort out this dew issue now.. this now shows my scope and camera combo is very capable of doing what I want to do, I just need to tame a few small issues to bring it right up to scratch... (oh, and organise my filters!
)
