Last night I stuck my new QSI683wsg8 on my 10" starfinder, with the Rowe coma corrector and a DMK41 guiding off the o.a.g.
I was just getting everything to focus and have a play.
So, polar alignment with a compass, no collimation, and focusing by hand, as I haven't got a robofocus adapter for this scope yet.
I took 5x2 minute subs through each of the LRGB filters, and combined the lot in pixinsight with a bit of stretching.
Question: I see red halos around some of the stars. Are these the dreaded astronomik filter halos, or is it more likely to be me over-processing excessively short sub frames?

Thanks for looking.
