An LRGB image of the Sunflower galaxy. The image was taken with my SW Esprit 150 and SX Trius 814 camera and represents just over 10 hours integration time.

I gave the very bright stars near the galaxy a very modest stretch and then blended this result with the result of the more highly stretched galaxy image. This approach generated some star colour and also reduced their distraction effect, in addition, it also allowed some faint nebulosity that surrounds the galaxy to be displayed.

The image was processed with my normal workflow which uses three software packages:

  • CCDstack: calibration, stacking & error rejection, Lum deconvolution and DDP stretch, RGB combination
  • Photoshop: mask generation(s), High Pass Filter, colour enhancements, noise reduction
  • Pixinsight: gradient reduction (DBE), Photometric colour calibration, green reduction (SCNR), noise reduction (TGVDenoise), sharpening (MLT).

The image was previously posted in the Deep Sky imaging section.



LIGHTS: L:11, R:19, G:15. B:17 x 600s, DARKS:30, FLATS:40, BIAS:100 all at -20C.

Stunning detail and depth in the image! feels as if I could reach out and grab it.

Thanks Galen ! :hello:

      TECHNICAL: R 20x480s | G 20x480s | B 20x480s | Artificial Flat Frame | ATIK414ex, Baader RGB filters, ASI120mm guiding though PHD2 | Meade LX90 8" SCT reduced to f/6.3
      Recently moved to a small beach/hamlet near Looe in Cornwall, and despite a street lamp being 15m away from my imaging spot, the skies here are significantly dark than any where else I have lived, so thought I'd try them out with a galaxy broadband image. Needless to say, I am looking forward to more clear nights!

      I tried making flat frames via the dusk light method, and no matter how little or much exposure I gave the image, DSS made the edges glow and the image extra noisy, not sure what I am doing wrong, so used the artificial flat frame method, which works well enough, just a bit more time consuming.

      I haven't imaged galaxies regularly, indeed, this is my fourth attempt at such an object and I need more practice, I got more data, indeed got 30xchannel in the end, but somehow couldn't get back to this colour balance and detail, so kept the smaller data set version.

      Anyhow, thanks for looking, really do love galaxies!

      First go with my Esprit 150 at M63. I particular like the galaxy colours and I was pleased to capture some of the surrounding nebulosity. The image is an LRGB and represents about 10 hours integration time.  A corresponding image within my Deep Sky II album was taken with my ED 80.

      My first go with my Esprit 150 at the Sunflower galaxy.  The image is an LRGB composition and represents just over 10 hours integration time. 
      Post processing followed by normal workflow with the exception that I found that the very bright stars required special attention to keep them under control.

      I can't quite believe this but, having checked, the last image I posted was in 2014!! Anyway, I spent most of 2017 building my observatory (thread here) having moved house, so finally I have been able to start using it.
      This is also my first LRGB image, so combining that inexperience with at least 3 years of cobwebs made this a bit of a struggle to process. I haven't done anything special - just curves and a star mask in Photoshop. Any C&C welcome.
      No tidal streams here - I thought about trying to go a bit deeper, but decided to hold back on the ambition since it's been a while Maybe I'll return to it later in the season once the moon has gone away. It could also do with some more RGB data.

      Thanks for looking!

      I'd been struggling with gettings subs longer than 60 seconds unguided, as I had to throw away over half of them. I suspected that it was due to periodic errors with the gears or similar with my Celestron AVX. I am using a 2.25 barlow, so my 130slt OTA was very prone to small errors. I looked into doing PEC training, and performed that on this night, and oh holy grail if that didn't produce miracles! I had only done two trainings and averaged them, and I then went from doing 60 second subs, and throwing half of them away, into doing 180 seconds unguided subs without hardly throwing any of them away! This really made me grin like a maniac that night, as it was just like flicking a switch and everything worked perfectly!
      So I immediately went to shoot a new target, which became M63. I had looked for galaxies to photograph and this one looked very appealing to me, from the images I found. I ended up gathering a total of 42 subs (+ the ones I ended up throwing away due to satellites, focus slip, dew on secondary etc), and 25 subs! There is still a lot of aspects I can improve on, but the simple fact that my capabilities took such a leap on one single night, simply amazed me, and definitely made up for the weeks on end that it has been cloudy/too windy! My polar alignment was very good that night, so I could probably have pushed it more, but I thought I should rather stay safe, and learn gradually.
      Processing is also something that still needs quite a bit of practise. I did like 5-6 versions of this one, and this is the one I liked the best of them.
