PK 36-1.1 (PN G035.9-1.1, SH2-71) Planetary Nebula in Aquila. Taken over several nights in Aug. 2008
with CCD Lab’s Q285M and a C8N at f5. Mount used was a Celestron ASGT. The H-alpha subframes
were 5 minutes, while the RGB subframes were 2.5 minutes. The final composite was processed in the
following LRGB combination: (Ha) : (R+Ha) : G : (B+Ha) and the total exposures were
Ha = 230 min, R = 40 min, G = 40 min, B = 40 min. Captured with Nebulosity, calibrated and sigma
combined in Iris with other processing using PixInsight LE and Photoshop CS. North is up.
