Had my first go at this target in narrowband with the QHY5L-II-M. Was very skeptical if i could use the extremely faint and noisy OIII data at all, but i think it did somehow work, although it's a bit on the noisy side.

all in all i'm very happy with the result, especially for my first attempt.
Not sure if i made the proper color balance though? Any tips and thoughts are welcome. :)

Captured with the QHY5L-II-M at 50% gain, unguided with a 135mm F/3.5 Olympus lens.
100x 120sec OIII
47x 120sec Ha

For a first attempt that's a great start.  More data, less noise will help but looks to be firing on all cylinders.  Bi-colour not my area of expertise but sure some here will provide you with some sound guidance.

      Hello
      I am wondering if anyone has a suggestion that might help me
      My imaging set up is an RC reflector with an FLI proline 16803 camera and 50mm Astrodon filters (LRGB + 5nm narrow band)
      I have had a string of issues...everything from my mount had mechanical problems to my telescope had issues with the mirror cell to some family distractions...but at long last I seem to have everything working with the exception of the Astrodon Ha filter.
      Attached are representative 30minute subframes of the horse head and Pacman nebulae in Ha, SII, and OIII.  I get similar results with different objects although for bright, broad spectrum targets like M42, I will get data from the Ha filter (much as the stars shine thru on the HH and Pacman) although even that data does not comport with other imager’s Ha images of those objects. The LRGB performance appears to be normal.  My hypothesis is that this Ha filter is defective, perhaps not centered on 656.3nm
      I have contacted Astrodon and exchanged a couple of emails with Cary Chleborad seeking some help.  At first he claimed there was no issue because with enough manipulation some data could be extracted from the Ha. Later, when confronted with the other narrowband frames and the obvious difference to the Ha, at first he ghosted me, but when I said I would ask other imagers for help, he responded with a new position stating that because of the way the filters are made and their robust quality processes, it is impossible for the filter to be defective and therefore something else must be at issue.  He does not offer a suggestion of what might be the problem, nor is he interested in having me send the filter back for evaluation. Frankly, I’m more than disappointed given the premium I paid for Astrodon filters
      All that aside, and taking Cary’s position at face value, does anyone have an idea of what might cause this behavior other than the filter?  In a perfect world, does anyone live in the Austin, Texas area who would be willing to try my filter one night and see what they get with their equipment?
      The attached link is to the raw, uncalibrated files right off the camera.  I think a simple blink process in PixInsight will show what I’m talking about.
      I’m a little at my wits end, please help!

      Hi all, my second attempt at imaging over multiple nights, captured 60 mins Ha and a couple of 5 mins on Oiii and Sii on Christmas evening, then added more Oii and Sii on the 30th
      Total of 60 mins Ha 25 mins Sii and 30 mins Oiii
      Hubble mapped - SII,Ha,OIII = R,G,B. The Oiii data was very noisy but I'm fairly happy overall, also the ZWO Oiii filter caused a massive ring around Alnitak when stretched !
       
      Comments welcome, I know it needs more data and I will need to learn to be more patient but the year is running out  🙂
       
      Thanks for looking and have a good 2020.

      I went to my family house in the countryside and was able to take some pictures during xmas eve.

      Total exposure: 6h
      H_Alpha: ~3h (730x15s) --> R, G
      Oxigen III: ~3h (710x15s) --> B, G
      I didn't have a view on Polaris and could not spend too much time drift aligning (it was xmas eve after all :D) hence the short exposures. Moreover I dont have the proper connection rings to put my flattener on my mono camera so all stars off center are a mess :_(.

      As new condition ultra narrowband 1.25" Baader filter. 3.5nm bandpass for nice small stars.
      Bought and loved it, but using a DSLR again and have no use for this filter.
      £140, can post.

      Selling my full narrowband set up for multiple reasons: I could do with the money and mono just isn't really doing it for me.
      £1000
      Includes:
      Altair Astro 183m Tec
      Baader Narrowband filters (Ha, OIII, SII and Clear)
      ZWO Electronic Mini Filter Wheel
      All associated cables/plugs
      T2 extensions to reach 55mm back focus for use with reducers
      Boxes and cases
      There is a scratch on the T2-T2 adaptor for the filter wheel and a couple of the labels on the filter boxes have been torn. But otherwise the important parts work perfectly well.
      Collection or postage via DPD.
      Buyer to pay postage and PayPal fees.
      No offers currently accepted, and I would rather not split
