Weinberger 3-1 (We3-1, PK 044+10.1, PN G044.3+10.4) Planetary Nebula in Hercules. This is a highly
evolved and extremely faint planetary with low surface brightness. Taken June 11, 12 and 13, 2010 on
nights with poor seeing. Imaged with CCD Lab’s Q285M and a C8N at f5 on a Losmandy G11/Gemini
mount. All subframes were binned 2x2. The OIII and H-alpha subframes were 10 minutes, while the
RGB subframes were 3 minutes resulting in the following total exposures L:R:G:B = (OIII+HA):(R+Ha):
(G+OIII):(B+OIII) (min) = (250+260):(54+260):(54+250):(54+250). Captured with Nebulosity,
calibrated and drizzle combined in Iris with other processing using PixInsight LE and Photoshop CS.
North is up.
