Leveye - it's superb - I'd encourage you to post these in the main Deep Sky imaging section rather than the "Get Started" section here - you are clearly delivering some excellent images

That is very nice, hard to know where to look there's so much going on in the image. Keep them coming.

It's a super image, you have some very nice star colour there and some nice hydrogen nebulosity starting to come through. My advice is go and get some more data, lots more, you can never have enough!

Could you get some more stars in next time? I don't think youv quite got enough there :D

Great pic by the way :)

Superb image. As Martin-Devon said, you're certainly ready for the more advanced section!

Everything's good, including star colour and depth. Again you have retained the background sky detail when so many black clip it out of the picture.

This is an object that really sings in Ha and OIII so to get it without a dedicated camera or filter is impressive.

Yes quite challenging and a light touch with these fragile images sure is needed i love it!

I'm starting to agree which Model do you think?

I like Atik for quality at a good price. There is no free lunch in CCD camera buying so beware of anything that looks too good to be true. The chip is not the camera. Mono is more flexible and far better for adding narrowband. Cost generally goes up with chip size but the 8300 bucks that trend by being a decent size without being too costly. However it does not compete with the smaller Sony chips on sensitivity or noise. I've imaged with most of the Atik range over the last few years and liked all of them.

      So far the start of fall has given some great skies, I have been observing most every night focusing on a few favorites including the Crescent nebula. This object shows some really nice detail at times and tonight when panning minutely around it I noticed a shade edge nearby... this immediately grabbed my attention and became the target of the night and turns out to be LBN 208. The 30mm ES 82/OIII/15" dob presented this object in direct vision once I had found it and is approx 1 deg away, or a bit less, opposite from the Crescents bright triangle of stars and so far shows oblong- more FOV would be an asset. I can't believe I didn't notice this object before.
      The sky mag is 21.8, NELM 6.8 and with above avg transparency. I must add that the NELM stars used were in Ursa Minor and that the mag 6.3 HIP 79420 is my usual target and tonight it showed easily in direct vision. Inspired I then rolled my eye around the area trying to get any "flicks" popping into view- and doing so HIP 77942 was caught at mag 6.8, my best yet. Cupping my hands around the eyes seemed to help.
      All in all a great night and before I forget...the Veils thin thread might not be so thin...

      The Crescent nebula. 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: 25 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, some faint clouds appeared but did not affect the frames significantly. Auto guiding was very stable.
      I increased the saturation by 30% and manually aligned the colour channel histograms. I stretched the red, green and blue channels by about the same amount to try and show the subtle difference in colour. The 600D is astro modded.

      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: 2 x 3min at ISO 800, Darks: 20 x 3min 20sec at ISO 800 (from dark library), Lights and darks separated by 30 sec intervals. Flats: 40 x 1/40s at ISO 800, Bias: 30 x 1/8000 at ISO 100
      Date of capture 05/06/2016. Atmospheric transparency was good (I only had a few minutes before morning twilight). Auto guiding was stable.
      I increased the saturation by 25% and manually aligned the colour channel histograms. I stretched the red colour histogram more than the green or blue to increase its contrast. The 600D is astro modded so does pick up H alpha in the red so the result is far better than the old D200. I need more lights. Also the 600D had much less dark noise that the Nikon, more of the field is usable now. No drizzling was done on this stack.
