  1. From the album: Photos from Bury

    The Wizard nebula NGC 6888. Processed using DSS. Hardware details: Camera: Canon 600D. Telescope: SW Evostar 120 with Baader UHC-S filter. Mount: AZ-EQ6 guided using a ST80 synguider. Image details: Lights: 30 x 3min at ISO 800, Darks: 50 x 3min 0 sec at ISO 800 (from dark library), Lights and darks separated by 30 sec intervals. Flats: 50 x 1/50s at ISO 800, Bias: 50 x 1/4000 at ISO 100. Date of capture 05/07/2016. Atmospheric transparency was good. Auto guiding was very stable. I increased the saturation by 30% and manually aligned the colour channel histograms. I stretched the red colour histogram slightly more than the green or blue to increase its contrast. The 600D is astro modded.

  2. Taken on Sunday evening with a 98% Moon. Comprising of 12 x 600s subs using an ED80 with a 0.85x FF, an Atik 383L+ and a 7nm Optolong Filter. Stacked in DSS, and processed in PS. Full frame and cropped, mono and h-alpha colour using NC Actions. Thanks for looking Adam.
  3. The cocoon nebula, IC 63 and IC 59, IC 1795, NGC 7380, M33, NGC 7023, NGC 6946. All images were taken with the William optics zenithstar 70ED with focal reducer, with 7nm h-alpha filter except M33 and NGC 7023 which didn't have a filter. NGC 6946 was taken with the skywatcher MN190, with no filter.
  4. After imaging with a DSLR for several years, I finally took the plunge and rinsed my savings on a shiny new Atik 428ex, thereby almost tripling my total ever expenditure on the hobby! I'm still having [http://stargazerslou...pacing/]trouble with spacing, so if anyone out there has ever connected a CCD to a coma corrector, I'd appreciate any help! Currently I have managed to reach focus using a shorter T2 extension, but the spacing isn't right. Anyway, very pleased with the camera itself. Very nicely made and it is a joy to use with the supplied capture software. Also, a single 10m sub was less noisy than my entire 28x10m stack of the same target with my DSLR! Even though only 10 subs, I stacked in sigma mode to remove the hot pixels. Is this a bad idea? How do I go about creating a hot pixel map instead? My processing leaves a little to be desired, I think, particularly with regards to the stars... And I will return for more data, this being one of my all-time favourite targets! 10x10m Ha, Atik 428ex at -5C SW 150PDS Vixen GP And here it is bodged together with my existing colour (55x2m) taken with my 450D For comparison, here is the Ha taken with my DSLR last year... quite a difference!
  5. Here's my latest, the Flying Horse Nebula (NGC7380) in Cepheus, aka the Wizard Nebula (though I don't think I can see a wizard, but I can definitely see a horse): 34x 300s at ISO1600, darks, flats and bias, equipment as per sig, DSLR at prime focus,Pixinsight. My wife and younger son say there are too many stars and I should photoshop a few out, and move the nebula to the right a bit... C & cc welcome, hope you like it ! Stuart
