Four double stars imaged with the TEC 200mm Mak/Cass at prime focus (3100mm) and a Canon 60Da in movie mode, 640x480crop, ISO400. Each movie was about 45sec. to 1 minute long in moderate seeing - 2 or 3 out of 5 at the Texas star party.
I used LYNKEOS aligning and stacking software which runs natively on my MacBook. After aligning the frames I selected the best 100 or so frames for stacking. No other processing was done.
I think the results are encouraging....
First, Mizar, (Zeta UMa), Mags 2.06 and 3.95, sep 14", PA 150 deg.
Alright, get on with it, Cotts!!!!
