Description

First light of my new RC12 Truss.

Short total integration time because I was very impatient to see a result after many months of inactivity :-)

Still some issues to be solved, but the final result seems cheering.

M12 is a globular cluster in Ophiucus.

It has an apparent diameter of 16' and a distance from Earth of 16000 light years, with very poor star concentration for a globular cluster.
