Once in Red Moon?

This is the moon taken with my astro-modified T3i/600D with the Astronomik 12nm Clip-In Ha filter and the Canon EF 200mm f/2.8L II USM lens.  Using this Ha-filter is a bit tricky as you need to set the focus on a bright object so I put the moon to good use and used it.  Also, it blocks most of the light so trying to locate object is very difficult because live view is useless.  In color camera Ha-filtered light (wavelength - 656nm) is in the red region hence the red color.

I did get a bit of imaging last night before the clouds rolled in.  The weather has not been good here lately and my FOV is limited so I have four projects going on at the same time - two with my main telescope setup and two widefield with my DSLR.
