      Description

      There is a lot of faint Integrated Flux Nebulosity around Polaris but it is very difficult to catch as equatorial mounts really struggle near the celestial poles. I had to do a lot of cropping as the images rotated. I will have another go at it with my RASA 8 but this is LRGB data I obtained as a menber of Telescope Live at the IC Astronomy hosting facility at 1250m elevation in Oria, Almeria, Spain. Red is 25 x 10 min, green is 26 x 10 min, and blue is 19 x 10 min, and lum is 28 x 10 min.
