Description

Abell 80 is a rarely imaged 16th magnitude PN in Lacerta with a mag. 19.6 central star. This is a bicolor HOO image, but this PN is dominated by H-alpha emission to such an extent that the OIII data barely add anything besides star colors. Total integration time was 7.6 h, including 5.2 h in Ha and 2.4 h in OIII, with mostly 12 minute subs at 0.48"/pixel. I probably should have used longer subs to capture the faint, blue central star, which is just barely visible when the image is blown up. The near lack of OIII emission accounts for why people who like to observe PNs visually through an OIII filter have trouble seeing this one. Perhaps they should be looking through a Red filter instead.
