I have been imaging the Horsehead and using a Schuler 10nm H alpha filter, William Optics fluorite triplet 80/480 with TV .8X reducer/flattener, Sbig 2000XM at -10C, Tak NJP mount.
3 x 15 minutes. When I get a few more clear nights I'll take a bit more, maybe 30 minute exposures, some UHC filtered images and luminance and colour shots.
