The Wizard Nebula in narrowband

[timc]

Not having posted any images for a while, I decided to finish off processing a narrowband image of the Wizard Nebula in Cepheus.  This object consists of an open star cluster (NGC 7380) and emission nebulosity surrounding it (Sh2-142) and lies about 8,500 light years from us in the Perseus Arm of the Milky Way. The cluster itself spans about 25 light years across. This nebula is best imaged in narrowband and I have used the Hubble Palette colours (i.e. red=SII green=Ha and blue = OIII) to produce the image.  I imaged this object using my TEC140 (5.5inch) refractor at f/7 on a Paramount MX mount with a QSI 690wsg CCD camera and Starlight Xpress Lodestar guide camera. I used an old data set which I collected over various sessions in 2016 and 2017 and the final image consists of 13 x 10 minute sub-exposures for each of Ha, SII and OIII, giving a total imaging time of 6 hours 30 minutes. Data capture was with Maxim DL, calibration and deconvolution in CCD Stack2 and image processing in Photoshop CS5 and Topaz Labs Denoise and Sharpen. Thanks for looking.
