Cats Eye Nebula NGC 6543
The Cat's Eye Nebula (NGC 6543) is one of the best known planetary nebulae in the sky While there are many images of this object, this rendition has captured the extremes of this difficult target. For the very faint outer halo 23- 1 hour exposures in O3, for the very bright core 10-60 second subs were gathered and for the rest 15 minute exposures, all assembled together in this cosmic halo in deep space.
Location/Date: Taken at Stellar Winds Observatory, a/k/a Stan Watson Observatory in Animas, NM from May 8th through June 12th, 2018.
Equipment used: PlaneWave 24" f6.7 on a PlaneWave HD200 mount and SBIG 16803 imaging camera.
Exposure times: Luminance 300 minutes, red - 270 minutes, green - 270 minutes, blue - 270 minutes, O3 1380 minutes and O3, HA, RGB for the core. 10-60 sec images., All second sub- exposures at bin 1x1
Processing: All data was calibrated, aligned, combined in CCD stack. All other processing done using CC Photoshop and PixInsight.
