Lunar Blueprints

This morning, before stowing equipment for the duration of upcoming days of cloudy weather, we aimed the 11-inch scope at Earth’s waning gibbous Moon. Images were captured at about 7:50 AM EDT, after the sky had turned to blue, lending its color to Moon as viewed from Earth.

The big Celestron SCT remains in need of adjustment or, possibly, overhaul but does deliver some pleasing results! We’ve been struggling but have not yet achieved best acceptable collimation, so the scope hasn’t spent much time on the permanent pier in the observatory.

The sort of flaw that one will see from telescopes that are out of collimation — alignment of the light path within the telescope — is stars that look a bit like comets, and focus difficulties. After several efforts we are not where we need to be with the C11 to use it as our primary observatory instrument.

Unfortunately, due to lack of space, we can have only one telescope at a time on a permanent mount beneath the dome. We are considering next steps which include acquisition of a new primary telescope, upgrading of the mount, and means of mounting two instruments at a time on the pier.

As mentioned, cloudy, rainy weather is expected to be the rule for the week ahead so the telescope is parked, and accessories stowed. We’ll be working a bit on our meteor camera and thinking about where to go from here.
