Hi folks,
My 2nd attempt at bicolour NB imaging. This one from my suburban Melbourne backyard, 3 hrs of 5nm Ha (red) under a full moon, 2 hrs 5nm OIII (blue) just before moonrise. (thanks for that tip RickS) and a Synthetic green channel.
Had to do bicolour because of the weird dust thing that happened that stuffed the SII subs. (see my post in the Astro imaging forum) Seems the other subs processed out the dust ok.
I'm learning lots doing this technique and getting small wins along the way - these are my first ever 15min subs - woohoo! Taken using a 2nd hand untuned EQ6 that the seller thought was only good for 5-7 mins max, lol
Pretty amazing what these filters reveal up there - sooooo much more info than on my old OSC. Still a bit noisy though - Looks like it could use another say 20hrs data judging by the other amazing NB images recently posted here by Paul Haese and others!
Tips and criticism welcome, it's the only way to learn.
Thanks for looking.
High Res here…
