Skies are starting to clear! Here's 20.5 hours of Caldwell 36 with 2" average FWHM on 30 minute L subs in 21.2 SQM skies. NGC 4559 (also known as Caldwell 36) is an intermediate spiral galaxy with a weak inner ring structure in the constellation Coma Berenices. Distance estimates for NGC 4559 range from about 28 million light-years to 31 million light-years. The Luminous Blue Variable (LBV) in NGC 4559 experiences repeated supernova-like outbursts.
