Description

This is a first light for my FLI ML16200 camera. It is a short 2.5 hr test shot LRGB of M101. Afterwards I discovered considerable dirt had encrusted the entire surface of the objective lens of my APM 130/780. That definitely scattered some light and caused some of the focusing problems I had which should hopefully now at least be improved after subsequently cleaning the lens. But this will be it for M101 this year.
