I imaged M-84, M-86 and friends a few nights ago between clouds and tree branches. Used the Canon 40D at ISO1600 through an 80mm Stellarvue Nighthawk II, a W.O. 66 mm guidescope, Orion Starshoot autoguider, all mounted on a CG-5. Moderate light pollution, so used a light pollution suppression filter. Series of exposures ranging from 90 seconds to 210 seconds stacked in DSS and processed in PSE4.
Probably need some more practice. APOD image for today:
