So just an update on this, been thinking about it again lately..
I was hoping to get a 6" newt, thinking they'd be around 1000mm focal length, but from looking this morning, they're mostly 1200mm focal length, giving f/8 focal ratio.
It looks like Skywatcher have an 8" newt (SW600) with a focal length of 1000mm, giving f/5 focal ratio for around $600 - perfect for what I'd use it for (deep space imaging).
Anyone else got any suggestions for a ~1000mm focal length, fast focal ratio newt with a 6" or 8" mirror?
