Teutsch 1 (Te 1, DSH J1957.3+2639, PN G063.9-01.2) Planetary Nebula in Vulpecula. Taken over several
nights in July, August and Sept. 2015. 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 30 minutes binned 2x2,
while the RGB subframes were 4 minutes binned 2x2 resulting in the following total exposures
(HA+Oiii):(R+Ha):(G+OIII):(B+OIII) (min) = (960+960):(52+960):(52+960):(52+960). This image is
up-sampled from the original and displayed at 0.57 arc-seconds per pixel. Captured with Nebulosity,
calibrated, sigma combined in Iris with other processing using PixInsight LE and Photoshop CS.
