M1 Crab Nebula Ha/SII/OIII/Lum


Recommended Posts

Not posted for a bit, but I did recently capture some half way respectable OIII data for the Crab, which I've here combined with some Ha/S/Lum data from last year - some of it reprocessed.   This is with the C9.25 with reducer and Atik 460, which I think gives a nice image scale for this object if you want to see the pulsar properly and a bit of structure (but don't bother at this scale without an off-axis-guider).   Colourful Ha(red)/S(green)/O(blue) palette :-).  (About 12 hours all in)

Very nice indeed, gorgeous colours.

I have imaged this briefly before with my ED100 but i am going to attempt the impossible this year and try it with my newly acquired skymax 180 at prime focus.

Nice structure in there.

Unfortunately it's just a bit on the small side for my 130 Triplet, though I have tried.

It's quite a special object at any focal length.  I've tried with my Esprit 100, but the SCT is about right if the seeing plays nice.  This image is very much seeing limited; those central stars would sharpen up in the right conditions.

I missed this one.  You are right - the image scale is spot on, and you've got the pulsar nicely.  That's very good detail, Tim, I like the colours, and even the stars are not too bad...especially for a C9.25....

      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!
