NGC 281 captured over 2 sessions on 15 & 16 Nov 2019 during a full moon. iTelescope T5 based at May Hill, New Mexico. Ha, Sii and Oiii filters used to capture 10 subs of each of 180s each. Oiii subs badly affected by capture at less than 90 separation from full moon and captured again outside full moon. Subs stacked in each band using Astro Pixel Processor. Ha, Sii and Oiii subs combined using Photoshop and processed using Astronomy Tools and StarTools. Sii mapped to R, Ha to G and Oiii to B.
