Description

Back at last, after two months of clouds! Haven't even checked astrobin in so long; have a lot to catch up on with what everybody has been doing. :-)

This is a composite of narrowband data from last night, and RGB data for the stars from last year.

One other minor victory is that I got my OAG working for the first time! Turns out that the right spacing is a 3mm extension tube + the clear plastic focus adjuster.
