~9 hours on M 33 with an unguided AG12


Recommended Posts

Ahoy mateys!

I finally had the time to process some of the data I've acquired during this autumn, my current workload have "forced" me keep shooting completely automated data from my roll-off-roof observatory 12km outside my city.

This have been by far one of the toughest targets to process, even though I had quite a pile of data to juggle with, there's endless of stuff embedded in the spiral-arms that took great concentration and discipline to bring out without throwing off the rest of the image. Data aquired during 5 different nights, shooting the subs when the target was in the highest position of the sky.

I've also included an annotated version where tons of dss2-galaxies are marked and labeled with magnitude. Moonlight during the lum-acquisition limited the background-depth somewhat.

Aquisition:
ACP + Scheduler
MaximDL
FocusMax
Telescope: Orion Optics AG12
Camera: QSI 583 wsg-8
Mount: 10Micron GM 2000 HPS
Guiding: Unguided
Exposures:
Lum : 77 x 180s
Red : 20 x 180s
Green : 20 x 180s
Blue : 20 x 180s
Ha : 12 x 600s
Total time: 531 minutes / 8.9 hours

I've just implemented a smooth transition "mouse-over" function for annotated images on my homepage, it's very interesting to spot the weak background-galaxies without having to alt-tab between the two versions...

Thanks a lot for the kind and encouraging comments ppl! Both platesolving and annotation-info was made using PixInsight : ImageSolver and AnnotateImage scripts

Stunning level of detail and considerable work/dedication in the processing.   The annotated version looks very professionally done, extremely useful though I prefer the naked image - is this information derived from astrometry.net as a plate solve on the final image?

Heh heh. That's good! That's very good indeed! Delicious detail and the familiar processing skill which hauls out the detail without any sign of 'processing' whatever. Stunning, Jonas. You are a world class player.

Unguided? Well, your mount does guide on itself! I wish mine did!!!

Lovely.

Jonas,

That is a remarkable image, your processing is perfect. Did you use PixInsight on this? I have seen

many overprocessed images done with PI that end up looking like paintings instead a pictures.

But none of that here! Great scope too!

Why only 3 min subs in lum?

Best regards,

Pieter

Fantastic Jonas! I like the HII areas in particular. Quite often th HII regions in M33 seem very bright but with no detail at all ( I think someone else used the word "painting") - not here! Plenty of details within both HII regions and star fields

Excellent Jonas,

Beautifully processed, you made it look effortless. Super pic. Lots of detail, and silky smooth. Lovely star colour, and I did notice on the larger version, they are a little diamond shaped. Is that from the spider in the scope, or was that from star work in the processing?

Tom.

      Finally I have something like First Light with the ODK12. This is just 6 x 600 sec subs Luminance with the Moravian G3 16200 and Chroma filters. Sigma Add stacking in AstroArt 7 followed by a slight crop to get rid of dither edges, Gradient Reduction (As the moon was starting to interfere), DDP and Unsharp Mask.
      Calibration was with Darks and Flats only as I had neglected to do Dark Flats *slapped wrist*.

      Reduced 50% for upload and JPEG. Yes it's a bit noisy, and I think I may have focus issues.
      C&C welcome as usual.

      M33 captured over 4 nights, 16hrs of data using 300sec subs, darks from library, mixed flats for an average and bias frames. Camera: Canon 600D. Everything put into Deep Sky Stacker and the resulting image processed in PS.
      I used a video made by Scott Rosen on processing to help me process and I learnt some really powerful techniques to use in PS.  I think this is my best processed image to date, so I feel happy I have made some progress. Looking forward to reprocessing my old data armed with the new knowledge 🙂.

      At the same astro party where I shot the Pleiades and partially Iris + the surroundings, I started gathering data for M33.
      For this image I used only a SkyWatcher 150PDS through which I recorded the photons on an ASI1600MMC.
      Curiously enough, I shot ~3.5h of luminance there under Bortle 2 skies, but a simple STF in PixInisght revealed less details than in 4h of luminance (through a LP filter) shot from home under Bortle 6-7 skies.
      Nevertheless, I put all the luminance together, I shot another 40mins of each RGB + 1h45min of Ha and made an image. A bit of colour only I also borrowed from an image I made 2 years ago, but in a small ratio.

      I've often wondered how my post processing skills have changed over the years, so I decided to find out by extracting some data which I acquired c2.5 years ago and performing a reprocess on M33.  The LRGB image with an Ha blend into the red channel represents just over 15 hours and was taken with my ED80 on my NEQ6. 
      The main post processing differences are:
      - I corrected for a slight camera tilt via PS, this results in slightly oddly shaped stars towards the edges of the frame. You should be able to see theses defects in the old image if you zoom in.
      - PI's Photometric Colour Calibration was used on the new image. 
      - PI's HDMRT was used on the Lum to increase the contrast (before I used the PS High Pass Filter)
      - PI's Dark Script Enhance was used to enhance the galaxies dust lanes.
      So, still a mixture of PS and PI but now with more PI.

      (My original result from 2.5 years ago is in the album Deep Sky II).
