PN G117.5+18.9

IC 1454 (Abell 81, PN A66 81, PN G117.5+18.9, PK 117+18.1) Planetary Nebula in Cepheus. Taken
Sept. 29, 30, Oct. 01, 02, 03 and Oct 09, 2021. Imaged with Starlight Xpressí SX-825 camera and a
Celestron EdgeHD 9.25 at f10, on a Losmandy G11/Gemini mount. The OIII subframes were 12, 15 and 20
mintues, the H alpha subframes were 15 and 20 minutes binned 1x1, while the RGB subframes were 4
minutes binned 2x2, resulting in the following total exposures L:R:G:B = (HA+OIII): (R+Ha):(G+OIII):
(B+OIII) (min) = (390+ 430):(56+390):(52+430):(56+430). Captured with Nebulosity, calibrated, sigma
combined in Iris with other processing using PixInsight LE and Photoshop CS. North is up.
