My favourite image. Over 10 hours of exposure time, over three night. Made up 10, 15, 20 and even 40 minute exposures (subs) with literally hundreds of calibration frames to help process the image correctly. This image took four complete processing sessions from scratch to get it right – and in total took me over 2 weeks to process.
Ionized Sodium light for Red light, Hydrogen Alpha for green light and doubly ionized oxygen for blue – gives this amazing effect – called Hubble palette. Called that because this is the style of the images from Hubble Space Telescope.
