  1. Cygnus Wall in SHO (Hubble Palette)

    Woah! You've really done something special there. You've achieved a perspective that makes it clear the dark areas sit in front, not behind the illuminated areas, with the stars sitting in front of these. Love it.

    I normally use the following for colour balance: Dynamic Background Extraction to remove any gradients (including colour gradients) Background Neutralisation Colour Calibration With the latest release of PixInsight there is a new colour calibration called Photometric Colour Calibration which I will experiment with the next time I collect data. I'd recommend the tutorials here as a good place for advice on processing: http://www.lightvortexastronomy.com/tutorials.html I also bought this book after it was released: https://www.firstlightoptics.com/books/inside-pixinsight-book.html I'm more a cook than a chef when it comes to processing. I can just about follow the recipe but don't ask me to explain how it works or how you could adjust it!
  3. The "No EQ" DSO Challenge!

    Those are lovely. There sure are some nice advantages to a fast wide aperture! Though there are probably just as many disadvantages
  4. Bubble Nebula

    Yes. And now they are aligned I'd take a look at the colour balance. Your background sky has a lot of blue/green. Did you run the background neutralisation process?
  5. Bubble Nebula

    Lovely shape in the bubble but it looks like your red or Ha isn't registered correctly. I'm seeing it shifted in 300 degrees direction. You might want to check your star alignment again.

  7. ANOTHER Elkephants trunk in Ha

    For me it's a black dog looking just over my left shoulder. Either way, I love the close up. Such a different way to show off he trunk.
  8. That's a seriously moody region. Lovely capture!
  9. The "No EQ" DSO Challenge!

    You can apply almost all processing techniques to a jpg...you just shouldn't! Jpgs are 8 bit and compressed so they destroy data which means tools like curves can have terrible results, making them look very 'stepped'. You're always better working in at least 16 bits and uncompressed (e.g. TIFF or FITS) so you can work over a better range and not have the steps seen in a jpg. PixInisght comes with a long free trial but it requires it. I needed lots of tutorials and ultimately a guide book to really start to use it well. You can achieve the same results in Photoshop if you know how. I can do a little in Photoshop, such as level and curve adjustments, but I find the tools in PixInsight more in tune with the way I think. As I said above, I only applied some crude adjustements to see what was under the colour cast. You will be able to achieve far more using the original data and taking a little more time than I did
  10. The "No EQ" DSO Challenge!

    Really nice first attempt. There's a lot of data hidden behind that blue cast. I don't know how to fix it in Photoshop but a quick pass through PixInsight's ColourCalibration and some crude curve adjustments shows you this. I've broken the stars (they are all showing orange) but there is a lot of colour in the nebula that you could bring out.
  11. Do you image all night?

    I personally would never take the risk. It's expensive equipment and it would be totally uninsured. I do retire indoors to watch some TV while I image and have a second computer indoors connected via TeamViewer so I can monitor what is going on. I usually pack up after a few hours.
  12. The "No EQ" DSO Challenge!

    Same. I set up tonight with the intention of getting 3 hours of Ha. I failed to switch on DST so my first StarSense align failed. When I did get aligned and switched on the camera it showed a massive smear somewhere. So I stripped it down and cleaned it. Realigned and now the sensor was covered in dust. I would still have to do two more aligns and it was getting so late I was concerned about waking the neighbours so I've just packed up. I think I'm going to have to wait until August.
  13. NGC7000 North American Nebula.

    I love the framing. You get just a little more field of view with the DSLR which matches this perfectly. As Tim says...very vibrant.
  14. Here's an article on high ISO noise reduction. http://www.learn.usa.canon.com/resources/articles/2011/high_iso_noise_reduction_article.shtml I suspect you will achieve better results with it off and using your noise reduction techniques of choice.
