Date/Location
Notes |
15 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. Ha_HaRGB,
where Ha:R (80:20) was used for the Red channel, and Ha for Luminance. |
