20100319 Sun (big prominence again)

Tele Vue Ranger with NGF-CM, Solarmax 40 with BF10, Lumenera LU070M, no focal reducer used. I have used that drift-and-expand technique to capture a full disc shot, except the T-max can be adjusted more carefully, everything work fine.

I've added a light shield to avoid light leakage into my board version Lumenera, it works out great, just 2 minutes of work.

Full disc taken with drift-and-expand method:-
