The Cygnus wall in Ha

Recommended Posts

EQ6-R Pro, ASI1600MM, ED120 + 0.85x reducer, Astronomik 6nm Ha filter. 2 hours integration (30x240s) 50 darks, flats and dark-flats.

Windy night, near full moon

Captured via SGP, Guiding PHD2, Processed in photoshop.

This is why I wanted to get into narrowband imaging, Taken on Sunday night from south Edinburgh (Bortle class 6) with a nearly full moon in the sky (95%) and I can still make the most of the limited opportunities we get here.

OIII filter is next on the list.

Nice. With more data this would be fantastic.?

Thanks, really just testing the new camera but I am very happy with the results from a not ideal night. ?

Looking really nice - you have some great data there! What settings did you use for these 240second exposures?

Fab image ?? Unfortunately Oiii isn’t as resistant to moonlight.

Thanks Steve, just sticking with unity gain just now, 139 / 21 offset.

I don't have a filter wheel yet but the camera comes with a 1.25" screw in filter adapter which works very nicely. giving minimal vignetting

Thanks.

I had heard that. about OIII, would a 3nm astrodon/chroma filter make a difference in moonlight ? (hope not I really cant justify the price tag to my wife) .

Rob.

Thanks, Rob -those settings are working well for you.

You can take some credit for it Steve, "Making every photon count" was purchased along with my first "real" telescope a few years ago ?

      Hi, I just published a video of how I am cleaning my filters - I thought I might do this while my telescope is back at service due to some kind of astigmatism.
      How do you guys clean your filters? it seems that every dust particle finds it way to the filters just as you are done cleaning them, and to sit in a damp bathroom seems kind of a mess...

      Anyway, here is the video

      As I have replaced them with new-style versions, I have two old-style ZWO 36mm unmounted narrowband filters for sale:
      - H-alpha
      - S-II
      They are pre-2018, so with both sides silver instead of yellow&purple, and come in the original, but opened, packaging. Condition like new.
      Attached images have been made with them. Any decent price will do.

      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 :_(.
