Date/Location

Notes
27 December 2013 - Las Cruces, NM

Backfocal distance now correct, focus-lock I believe is affecting optical train and causing slight coma in one corner - this is only because I currently just manually focus this smaller scope. Only enough time to collect Ha data and went behind my house after only getting one color channel, so no color for this one, for now :)
