Kronberger 1 (Kn 1, PN G040.9+08.3) Planetary Nebula in Ophiuchus. Taken over several nights
in July and Aug. 2013. Imaged with CCD Labís Q285M camera and a Celestron EdgeHD 9.25 at f10,
on a Losmandy G11/Gemini mount. The OIII and H alpha subframes were 20 and 30 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) = (480+530):(60+530):(60+480):(60+480). Captured with

OMG what inspired you to image this?! It looks absolutely amazing, a serene and tranquil vision of stardeath! The DSH planetaries need more attention!
