Hi Ian,
Yeah, thats roughly what I hoped to do, but I found that when I hung the CCD on the focuser, even when the focuser is set at its furthest from the OTA, the Moon comes to focus way beyond the CCD – hence the need for lots of adaptor tubes. 🙂
Inevitably, I didn’t find this out until I had run the focuser across its full 3″ range in 1/8″ jumps looking for star images at each position. I was so convinced it should work that I did it twice with different exposures. Saw a couple of bright stars travel through – while filling 25% of the screen – none anywhere near in focus.
So, that was 2 clear nights wasted as at -4C I wasn’t sitting out there for more than 2 hours at a time.
More after I have a look inside the Moonlite…
EDIT: No glassware found in the Moonlite. Now wondering why the focus knob was modified…
