Long time between quick cones, albeit of a very different nature. Equally paranoid about things however!
Just managed to get about 20 minutes red and green tonight with hopefully some blue tomorrow. Worked out a nice sequence in SGP: image, pause, flats, pause, refocus for the new filter, resume.... doesn’t take too long just trying to match HFR readings when focusing with a new filter is a bit of inspired guess work....
I’m working hard so expecting some luck!
