Hi all,
This imaging season I have been trying to do a few things in a bit different way, and with mixed results. For example, I was quite pleased with my attempt at the
Lagoon, but pure 100% narrowband
Trifid was a bit of a let down.
While working on my first
HaRGB image which is yet to be completed, I thought of making an attempt at revealing a tad more of the Helix. I already had 50 hours of Ha at f4.5 from last year, so I just added another 50, but this time at f6, also with my trusty 4" guidescope.

In spite of making a few attempts at putting the data together, somehow I cannot show more than what I already had last year, and I do not want to overstretch the data because IMO my overstretched Helix always looks plain ugly and flat. Perhaps the subs were too short and I should have gone for 30-minute subs or longer.
Anyway, on top of now accumulated 101 hours of Ha, I already have 30 hours of NII and 20 hours of OIII from last year, so may as well go all the way and try adding some SII to the mix and see what I will manage to cook up with all four
Thank you for looking
Suavi
