Sharpless 2-68 (Sh2-68, Yerkes Mcdonald 15, PN G030.6+06.2) Planetary Nebula in Serpens (Serpens
Cauda). Taken over many nights in August 2010. 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 2 minutes resulting in the following total exposures L:R:G:B =
(OIII+HA):(R+Ha): (G+OIII):(B+OIII) (min) = (350+290):(50+290): (50+350):(50+350). Captured with
Nebulosity, calibrated, sigma combined and resampled in Iris with other processing using PixInsight
LE and Photoshop CS. North is up
