Iris Nebula (NGC7023) in LRGB


Recommended Posts

Here's my latest,  taken over a couple of nights this summer:

37265584106_cb75984eb8_b.jpg

17x600s L 1x1, 17x180s R,G and B 2x2 binned (don't like the 2x2 binning, no binning for me from now on).  Flats, darks and bias, equipment as per sig, Pixinsight.

 

The Iris Nebula (NGC7023) in Cepheus is a dark nebula and reflection nebula.  The dark cloud of inert dust and gas obscuring the background stars is illuminated in the centre by a mag-7 star, reflecting pale blue starlight.  It is 1,300 light-years away and 6 light-years across. 

 

Hope you enjoy !

      Hello all!
      The weekend that just passed we went to my girlfriend's parents. The skies in that rural area are pretty much as good as you can get. I don't have an SQM reader, but Clear Outside estimates 21.91.
      I didn't take the EQ6R with me, I still consider it a big lump of iron, and the AZ-EQ5 should be on its way back this week as a Stellar mount. So I used the EQ5 which was left in the car for a while. While the tracking/guiding on the RA axis is quite good, the DEC control jumps a lot after multiple consecutive guiding commands, I blame the "enhanced" handset.
      So with all the drawbacks, I tried to do align the mount as good as I could and I put the 72ED with the ASI1600 on it and a finder-guider.
      Perhaps also focus could have been done a bit better, FWHM in the subs was 3.x.
      Below is a quick process from last night, no deconvolution yet and a purple area at the bottom that I have to fix. 58x120s lum, 30x120s each RGB.

      Hi Guys,
       
      I thought I would share with you my first DSO taken with my new Orion 8" Ritchey Chretien F8 Telescope.  The frame is made up of 12 x 4min shots, no light or dark frames, using my Sony A7Rii camera.  The camera had the long exposure noise reduction switched on, which does help to reduce the total number of stars captured by the camera, as the Sony A7Rii does tend to overdo the number of stars captured.  The telescope was mounted on my trusty skywatcher NEQ6 mount and the guiding was via PHD 'of course' via my skywatcher ED50 guide scope.
      The shots were taken from my back garden in Stowmarket, Suffolk where I believe I am a Bortie 4 location, so the skies are mostly dark, with just a little light pollution from the main town, no filters used.
      My normal telescope is a Skywatcher ED100 Pro Esprit F5.5, which is an incredibly sharp scope, but with a wide 550mm field of view, great for capturing the whole of Andromeda but a struggle with smaller images like the Iris Nebula.  I will say the Orion RC scope did need to be collimated out of the box, which was a little disappointing, and it was not just a little out of collimation, it was a long way out, but with the use of a collimating tool, I soon had it dialled in.  
      First impressions of the Orion Ritchey Chretien 8" Telescope are fair, not super impressed, as it is nowhere near as sharp as my ED100 Esprit, but then this is to be expected based on price and telescope type, however, the pictures it has produced are pretty good, if you downscale the full 42MP from the Sony A7Rii camera, as can be seen in this picture.
      I purchased this 8" Orion Ritchey Chretien OTA mainly for Planetary work, but as yet I have not had a chance to 'get onto' a planet, fingers crossed some clear nights will arrive soon, so I can try.
       
      I welcome comments,
      many thanks

      Hi Guys/Girls
      I had a chance to get out in the garden last evening, had a go at capturing NGC 7023 - Iris Nebula, only managed to get 12 good shots, 240sec x 12, combined in Photoshop with Mean Stacking.  The dew was super heavy and currently I do not have any dew heaters (next purchase) so lost the battle after around 2 hours. 
      One interesting point is I captured these shots with the long exposure noise reduction switched on with the Sony A7Rii, so each shot took 8 mins to take and save, but as a result the noise levels were next to zero at 800 ISO, and at the end of the day the noise is always our enemy.  I need to try a real pro level 'cooled' astro camera just to see how much better it could be, as the Sony A7Rii is just stellar !
      I am very happy with the final shot, taken with my Skywatcher 100 ED Pro Esprit Scope on my NEQ6 mount, Skywatcher ED50 Guide Scope and Altair Astro ASI130mm camera, PHD2 of course.  The sky was nice and clear with low light pollution, as around 5 miles from major town.
      I do not take darks or flats or use Deep Sky Stacker, and I do not use filters, plus the camera has not been modified, so I am always delighted with the results I get from my set-up, as I have a deep level of respect for the hard work that most Astrophotographers go through to get the incredible images that we see here in Stargazers.
      I have read that some people believe that the Sony Alpha cameras have a tendency to 'eat the stars' and not show everything captured, to be honest, I always used a Canon 60Da for  many years for my astrophotography, until one day I though, what if my Sony A7Rii could be used, the first time I did this I released that it was time to sell the Canon 60Da, the 'Remote' (free) Sony software is almost as good as BackYardEOS, but the cameras are a decade apart in performance, the noise levels on the Sony are at least 4 maybe even 5 stops better than the Canon, that is the Sony A7Rii at 3200 iso equal to the Canon 60Da at 200 iso, so at 800 iso it is just so impressive.  As you can see from the picture only 12 frames, stacked in Photoshop (Mean). 
      Open to comments and welcome a discussion/debate,
      thanks
      Jamie

      An LRGB image of the Iris Nebula, representing about 11 hours integration time and taken with my Esprit 150.
      The Iris is a reflection nebula in the constellation Cepheus. The light from the very bright central star is scattered by the surrounding dust giving it a distinctive blue colour. Although not designated as an emission nebula, you can also see reddish regions close to the central star which indicate the presence of ionized hydrogen. 
      Also present is an open star cluster, which can be best seen through the triangular clearing of dust to the left of the bright central star.

      So after Carole helped me to realise that I was taking my flats wrong, I've reprocessed this image and finally the funny rings have vanished.
      Original thread
      TL;DR - I was underexposing my flats, which resulted in failure of calibration to remove vignetting, as well as it introducing weird red concentric oval rings.
      Last night was supposed to be clear, so I set up in the garden. Cue the Irish weather. I only managed to get PA and focus (you know, the most fun bits) and then the clouds rolled in.
      Anyway, so instead of imaging, I took a bunch of calibration frames. The setup was slightly different to the lights -
      1) temp 4 C instead of -1.5 C (no big deal)
      2) camera at different angle to telescope (can't correct dust motes)
      3) new camera angle adjuster in path (different vignetting and internal reflections)
      so I didn't hold out much hope that it would correct the problem. But it did! I used the new bias and darks to correct the new flats, and then the old bias and old darks and new flats to correct the lights. I'm so pleased I've finally figured out what was going on as it's ruined many images for me over the past year+.
      Thanks again Carole,
      Barry
