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.
