Like to many, the Ring Nebula was my first observed deep space object. Mostly this session was a test run to see if my renevated EQ6 and re-collimated & tilt-corrected SW200P are in working condition. But the data seemed fine with just minor field rotation, so here we go: the start of season 2015-16 with an old friend!
