This image was taken on the nights of 19, 21 and 24 October 2014 with a William Optics Megrez 90 telescope with a 0.8x focal reducer and using Astrodon narrow band filters. The Ha consists of 43 x 600s, OIII 14 x 600s and SII 9 x 600s. The OIII and SII were binned 2 x 2. The resulting images were then combined in the hubble palette.
