Ha ha... got your attention
Well, technically the GSO 6" RC is an APO ...
Spent too many days in hospital lately prevented me to use the telescope for a long time
.
The RC ride on a modified Celestron CI-700 (bearings, drive system, alt-az adjustment). Guiding was very frustrating, but managed this Trifid about 5h RHa_GOIII_B using the CCDT67 reducer with Atik's 314L+
@-20degC.
My processing skill was limited before the hospitalization, now I have to relearn again the what and how
...and working on the CI700 to improve the guiding.
