NGC 7023 The Iris Nebula

Recommended Posts

Hi everyone - it's been a while! 

This has been on my hard drive for almost 2 months and I finally got round to processing it...it was quite optimistic of me to try and image this from my Bortle 7-8 back garden, but I gave it a go! While the nebula itself is clear to see, all those gorgeous dust clouds surrounding it were extremely hard for me to capture from my location without a lot more integration time. I think I'll head to dark skies to capture this one next time, along with some more focal length!

LRGB shot with ASI1600MM Pro and WO Z73. 2.9 hours of integration time.

Full details here.

Thanks for looking!

Lovely backyard capture - hard to do a lot better than that without a dark site or much longer integration. Nice work! :)

Pretty Amazing, I live not that far from you in Bromley, so I know what your skies must be like.  Would never have thought to have attempted this one from home, so well done.

Thanks to everyone for the kind words...I think this is the type of target that I would need an obsy for in my light polluted skies...just letting the rig pick up the photons night after night to build up integration time.

Alternatively a few hours at a dark site...

Nice one, i was interested in the composition of this target and found this,

0000694.000&db_key=AST&bits=4&res=100&fi

I have only ever seen it Blue which i thought indicated Oiii but doesnt seem to be any!!

It's an LRGB target Roger.

Yes i know but i was wondering what actually gases it contained,

That is a fantastic image considering you location.  Beautifully processed.  You've managed to show the dust without blitzing the background.  I had a look at this a couple of years ago and gave up and my sky is Bortle 5.  Kudos!

As far as I'm aware Roger there isn't any significant gas there.  The colour is produced by starlight reflected off the dust.

Thank you! This was a clear night during galaxy season where there was nothing else worth shooting with my widefield rig...so I went for it....processing was tough as I had seen the beautiful dust-laden shots of the Iris from better skies, so I knew what I wanted to see, but it was clear that I couldn't push the background too far...

...I love all the nice comments...slightly odd that I posted this in June but it looks like the thread was unearthed by someone in November! I'll take it of course!

      Hi, I recently looked into telescope's & dso's again due to an interesting sight in the night sky 😉. 
      I wanted to get into telescope's etc... but my budget and other things got in the way. 
      This time there's no budget limit (that doesn't mean I'm bill Gates though).
      My main concern is size since I will carry the telescope with my bare hands (bag).
      I don't have a local astronomy club or telescope shop around so I don't know if an 8" Newtonian is too bulky/big. 
      Can someone post comparison pictures, if you have an 8" telescope (preferably newtonian, width and length)?
      Secondly I want to see dso's in the future (firstly beginner objects etc...) so the 8" is more adequate than the 6", but if an 8" is too big then I am okay with a 6" as long as it's much more portable.

      I was wondering what images of dso I could get with this setup. How and how much would my images improve if I added in a decent file flattened and what would happen if I exceeded the maximum telescope magnification with Barlow lens.

      Hi,
      After several years in the photography world I decided to take a plunge into astrophotography, haven taken pictures of the moon, I now plan to capture DSO, unfortunately, I live in a bortle 6/7, and was planning to shoot orions nebula but found out it stays below the horizon for the summer. This is why I turn to the forum: are there any DSO that can be easily captured with a DSLR, a tripod and some software like sequator, and that is visible in  summer too? Ideally if it can be near the zenith it would be best, due to the annoying sodium light streets.
      Also if you could post some images of DSO taken with a DSLR and a tripod ( and software of course)that would help me make an idea of what I should expect.
      The camera I plan on using is an old canon eos 550d, without any modifications.
      Thanks in advance,
      S

      I've been having another crack at DSO imaging lately, and I've managed to produce this from 6 hours of integration: 
      I'm quite pleased with it but I'm very new to image processing, so I'd be incredibly grateful if someone wouldn't mind having a go at processing my data!

      Image Info:
      Lights: 46x4min + 66x3min  Stacked with Dark, Flat and Bias frames Stacked in DSS and processed in GIMP Taken under Bortle 7/8 skies Gear:
      SkyWatcher ED80 0.85x Reducer Astro-Modified EOS 600D ZWO ASI 120MM Mini Guide Camera with 9x50 Finderscope HEQ5 Pro Mount There's some dust bunnies and other artefacts on the image that I know I could spend more time removing, however I'm wondering if I'm doing my data justice in processing!
      Thanks, Tom
