This
was going to be a more traditional SIIHaOIII blend but unthinkably
my beloved rock solid never given me any trouble in 10 years NJP mount, decided to throw a grub screw on a transfer gear and prevent me from being able to slew after the meridian flip
...I think I can fix it
Anyway, not sure when I will be able to gather the SII data now sooooo I threw what I had together into a Bi-Colour view of roughly HaOIIIOIII and luckily I had decided to collected a little bit of RGB earlier in the evening so I was able to tame the narrowband star colours a bit to match. I am really enjoying these narrower band pass 6nm Astronomik filters too
Be interested to know what you think as although there are many tri colour narrowband and LRGB versions around there aren't very many BiColour M17's out there
