I recently replaced the dome control electronics after the Foster Systems controller bit the dust and I replaced with a MaxDome II controller for rotation and shutter operation.  It’s working flawlessly so far and I couldn’t be happier.  I threw the 5″ refractor back in the observatory with the 16803 chipped camera for a widefield rig at 2.2 arcsec/pixel resolution.  Drizzle processing yields better star shapes/sampling than the low resolution would suggest.  Both images are cropped from the same image with 20.5 hours of total exposure time in the traditional Hubble Pallet.

We’re in Galaxy Season and without the 10″ RC I’ve instead focused on the 5″ refractor with a small pixel size camera to squeeze out some detail.  Imaged from the backyard observatory in ~20.5 mag/arcsec^2 skies.

M81 – Bodes Nebula ~8 hours of exposure time. LRGB with AP130GTX, AP1200GTO, Apogee Ascent A694, Baader LRGB Filters, SX-OAG, Lodestar Guider.


M82 – The Cigar Approximately 7.5 Hours of exposure time. AP130GTX, AP1200GTO, Apogee Ascent A694, Baader LRGB, SX-OAG, Lodestar Audoguider
