NB Helix
I have long meant to try this favorite in NB. So here it is my go at the Helix in narrowband with the ST2000 and RC10.
It took a few nights to get the data which is 15*24mins Ha and Sii, 8*24mins Oiii. The Sii images were so weak I had to ditch them and blend Ha and Oiii to make a synthetic R. I used the Ha as a L, so this is Ha, Ha/Oiii, Ha, Oiii. Wish I had read OPs first and would not have bothered with Sii....still they say you learn from mistakes not successes so now I must be wiser!
