M17 Nebula Narrowband in Tricolour
My first reasonable tricolour image using three narrowband filters from Optolong to create the colour. I assigned the Hydrogen Alpha frequency to Red, the Oxygen3 frequency to Green and the Sulphur frequency to Blue.
Total exposure for this image is 15 hours in total across the three filters.
