With the battery pack, the Ranger balanced very well with the SM40+BF10 + binoviewer... the two SCT correctors enabled me to observe the full solar disc, with GREAT detail... the most beautiful object that I ever observed with a telescope!!!!
I was addicted.
prominence extends far out from the solar disc, and then curved backward to form a filament on the solar disc... hard to take image... let me learn...
my new DC is not suitable for any kind of astrophotography, huge vignetting... at any zoom.
