Last night: a little sky window two hours long, just enough for a photography autodidact. This time I lugged the 10″ scope out, and went through the whole attach camera to gadget to eyepiece to scope thing all over again, strapping a variety of comestibles to the rear end of the tube to balance the extra gubbins at the front.
The combination of 35mm and Barlow which worked on the 5″ wouldn’t come to a focus at all, but the 35mm on its own and subsequently a 25mm both worked. I haven’t sussed out how to get a higher magnification yet, and this image (upside down as taken through a reflector) is nothing compared with the breathtaking eyeball view through my best 7mm eyepiece. But this will do to go on with.
