Description

This is just 1 hour of Ha data and 30mins on SII & OIII then mapping the data to RGB to get a colour image, (R=SII G=Ha B=OIII). Still early on in the data acquisition so I hope the other colours will come out more as I build up the data and also the noise will reduce overall. Might have to consider shorter exposures as the usual 10 mins is losing some detail in the centre due to a bit too much exposure. There's a lot more dust clouds than I expected and with more OIII data hopefully the running man will make more of an appearance
