Well i can do longer subs, though the DSLR really needs colder conditions to do it well, I am imaging in my back yard too with a 1/2 moon only a few deg away so gradients are inevitable.!
Im really happy about the star colours and colour in general its been something for so long i have only captured white stars or if a yellow/red star was dim enough it would bring the colour out.
now i have to properly polar align as last night i slapped the mount down did a 1 star manual polar align then started shooting
... tonight ill drift align as i cant see the octans from here and get some good going. I found that the finder guider is sensitive to polar alignment if its not right your guiding goes a bit skewif!
Thankyou for the compliments, it means a fair bit coming from people that produce good images themself.!
