Böhm-Vitense 5-1 (BV 5-1, PK 119+00.1, PN G119.3+00.3) Planetary Nebula in Cassiopeia. Taken over
several nights in Nov 2012. Imaged with CCD Lab’s Q285M camera and a Celestron EdgeHD 9.25 at f10, on
a Losmandy G11/Gemini mount. The OIII and H alpha subframes were 15 minutes binned 1x1, while the RGB
subframes were 4 minutes binned 2x2 resulting in the following total exposures
(OIII+HA):(R+Ha):(G+OIII): B+OIII) (min) = (330+315):(60+315):(60+330):(60+330). Captured with
Nebulosity, calibrated, sigma combined in Iris with other processing using PixInsight LE and
Photoshop CS. North is up.
