    Looks like stellar DNA!
  2. Manufacturing tolerances and not overly tightening each connector will often result in under or over shooting the desired spacing. This does look like a spacing issue and the best advice I can give is to get your spacing to be just a little too short, so the any star elongations all point towards the centre of the image, then gradually add spacers until your stars are round to the edge. It is easier to add spacers then to work back from being a little too long on the spacing (which is what your image looks like).
  3. That's a beautiful bi-colour image. And it really helps that the chip size lets you fit the nebula into a single frame. Nicely framed!
  4. Flaming star nebula to Jellyfish nebula

    I think that would make a great 1000 piece jigsaw! And every piece would have something interesting on it.
  5. Rosette Nebula - Thoughts Please

    Surely you mean 3.000000 copies? And back on topic...what a difference the new DBE has made. I don't mind a little star ringing. It's only noticeable effect (unless you pixel peek) is that it makes the stars pop. Not a bad thing.
  6. Try the new PhotometricColourCorrection process. Apply a default ABE then apply the PCC. You’ll need your focal length and pixel size for it to plate solve but it will try and balance star colours to thei4 catalogue BV.
  7. I've not thought of this before, but now you've mentioned the light cone, I wonder if this has quite an effect. If the light cone is only partially captured by the chip due to its size, the scope's effective aperture is reduced. So if you can get more of the cone on the chip, then you're actually increasing apparent aperture and you *are* capturing more light.
  8. The "No EQ" DSO Challenge!

    A good start. You’ve just started to capture the nebula. Did you take flats? If not, they will help. You should also make sure to crop any stacking artefacts before processing. I can see a little has been left at the bottom and that can make it harder to remove gradients, etc. But welcome to the wonderful world of imaging
  9. For a good walkthrough, I’d recommend https://www.firstlightoptics.com/books/inside-pixinsight-book.html which is also available as an ebook. Though the Light vortex astronomy tutorials are shown in a workflow order though not all steps are always needed.
  10. Worst Astro Image Ever? - SOLVED!

    This was actually my first thought. It looks similar to condensation/ice build up and over 10 mins it could have quite an effect. But I’m surprised the gradient looks similar in 1, 3 and 4 but more extensive in 2.
  11. Worst Astro Image Ever? - SOLVED!

    Oh. That’s the image? I thought it was the noise and you were imaging aurora:)
  12. You've really processed it well with lots of detail across the image. Often, a little is better than more and you've got it spot on. Although I'm not a fan of the mono-red look, it does show more detail. I find an inverted B&W can also show more contrast in the brightest areas, which often are hard to see. I guess our eyes (or at least mine) are more sensitive to shades of dark than shades of light.
  13. That's very strange noise. And more noise than I would expect from Ha and 6 hours of exposure. Are the subs calibrating correctly?
  14. Looks like a dragon’s flying into the frame. Though with your set up I was expecting pigs! Great detail but as Adam says, the blacks are a bit too clipped.
