Ellis-Grayson-Bond 1 (EGB1, HDW 1, LBN 624, Simeis 280 and others) is a planetary nebula located approximately 1021 light-years away in Cassiopeia.

Ha – 18x1800s – 540 minutes – binned 1x1
RGB – 8x300s – 40 minutes each – binned 2x2

660 minutes total exposure – 11 hours

Imaged from Dardenne Prairie, Missouri (a red zone) on September 15th, 17th, 27th, 29th, 30th and October 16th, 2018 with a SBIG ST-8300M on an Astro-Tech AT90EDT at f/6.7 603mm.

I also captured some OIII and a full set of luminance. I could not detect anything in the OIII and the luminance was much fainter than the Ha.
