ASTRO: M97

Hi:

I had more data for this, but unfortunately, once I started the stacking
process, I realized that just over half of it was ruined due to my secondary
dewing up. Didn't turn out too terrible, though I know it could have been
much better:

6x3-minute exposures using a Hutech modified Canon T1i DSLR
with a Lumicon UHC filter at f5 with a Konus 200 mm Newtonian reflector
Stacked and dark subtracted in Deepskystacker,
processed in Photoshop CS3

Mount: Losmandy G-11 Gemini (v4)
Autoguided with a 500 mm Orion shortey and starshooter autoguider

Correction. That wasn't filtered.
