Tracking seems a touch off, I suppose with the reducer it would be less noticeable. Colors are different... That camera of yours really pushes red very hard! Good to see you were out imaging though... Must have felt good...
A lot of good can come from a few sets of data at different exposures.. 5x5 mins + 5x2 mins and 5x1 min should give you a hell of a lot of dynamic range. even some 30 second subs could make a difference. right down to the trapezium...
Good to see you still remember how to use it all
