another Heart and Soul 2 panel - HOO

Recommended Posts

It seems that none of my glass optics doesn't want to play nice anymore. I started this 2 panel mosaic while shooting for the bubble area, on Ha, with the Canon 300 F4 L lens. In the beginning it went better, but at some point the IS elements decolimated and I just couldn't luckily align it ok again (by attaching back to the camera and focusing with the IS on and then detaching it). I tried one round with the O3, but then I switched to the Tair 3s.

The total on this target is like this: 6 h of Ha on each panel, 1:x h of Canon O3 + 1:15 of Tair O3 on each panel. That means ~17h in total. I might want to try to add more O3, but it's only a hope. The moon comes again and the forecast doesn't seem nice the next days.

I need a proper scope.

I think now that the Soul is stretched more than the Heart, it didn't seem last night.

Thoughts welcomed.

Clear skies,

Alex

Thank you all!

I think the colour rendition in the first is particularly natural looking

I'm aiming usually for something looking more natural, though I don't follow any rule in particular for this.

The second image is Ha only.

If possible, I'll try to add some RGB too for the stars, but I feel I'm stretching too far. I could finish during 2 clear nights and add some O3 too.

The forecast seems to change, but I should keep my fingers calm as last time when I bragged about this I was punished.

Nie picture. Still early days for these targets as they will be higher up over the coming months. So plenty of time to capture some RGB data.

Thank you, both!

Yeah, that's not working for me. I image from my balcony and I have limited view of the targets. Some of the targets are visible until the top window frame gets in the view - that's about 55 degrees in altitude, others - like these ones - are hindered by the lateral margins of the window frame.

Anyways, first try below. The Tair is not the best piece of glass. It works better in narrowband, but in broadband blue is just a tad better than the bottom of a glass bottle. Moreover, the Tair has exactly 300mm FL, whereas the Canon has 293mm. I couldn't fit all the Soul with the Tair when shooting the RGB. I have to take some more.

Damn window frames! I have similar issues when targets move further South, though this is my neighbours house...

Good luck.

A week ago I shot some more RGB more on the left side so now the soul is not cropped anymore. Now that I came back home, I also reprocessed the Ha so now the soul is about as bright as the heart.

The results might be not the final ones, especially if you have some tips and I also shot some S2, but this one does not fit very well with the others so I have to shoot some more.

HOO and RGB(stars)-HOO(nebula). And Ha only.

      And i will try again.

      Hi guys,
      So on Tuesday night I spent the evening imaging the moon with my Celestron 9.25 SCT and DSLR as shown below and am happy with the images I collated (I only took images as I did intend to take capture video but I got carried away and time was getting on).
      I have approx 350 jpeg (and the equivalent in raw) images and have used the Microsoft image composite editor to stitch the frames together without editing them first etc but I wonder if I'm going the images an injustice?
      I'm not ready to pay for editing software as I know there is a lot of very good free downloads out there and I'm asking for recommendations. Should I be processing the frames before/after stitching and what software would you recommend? Please offer any advice you have.
      I will post the resulting image once I'm happy with the outcome 😁
      Thanks in advance,

      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!

      A close up of the open star cluster IC1848 which is embedded within the Soul Nebula (Westerhout 5). 
      The LRGB image represents just over 21 hours integration time and was taken with my Esprit 150.
      To capture the detail of the emission nebula, I gave it an Ha blend into both the Lum and Red channels.
