Ok I'll get the ball rolling.
F/10 Celestron HD-102 EQ achrocatic refractor. Autoguided with K3 through a Meade OAG, 260 sec single shot, ISO400, Canon 300D. Focuser R&P, focus assist with DSLR Focus.
Substantial chromatic halo appears over this time frame. Less obvious but still present in greyscale image. No processing apart from croping and greyscale
