A belated first light effort with my new PGR Grasshopper3 with the Sony IMX 252 sensor. This was really just a test to see what plate scale a 2.5x PM would produce with the smaller pixel size of this sensor in my particular imaging system. It worked out at F11.
Since this effort I have changed the imaging train, adapting it with a 3x Seibert modular barlow and a home made bush to get to F 15.5 but have since had mainly horrific seeing.
Have attached an animation from the first light morning at F11 which features the GRS and a shadow transit of Io.
