Thanks Greg. I’ve toned it down a fraction and lessened some of the maroon halos. Feels a little less forced to me now, although still quite blue... could go forever on this of course!

I’m astonished at how much I can get form the 8” Newt and once the backlash is eaten up with the guiding on the EQ6-R I can regularly get below .5 RMS with my OAG so really happy with the current setup. Still need finer colimation (one terrible corner which I think is my secondary) but centrally things are mostly okay.
