Horsin' around with the QHY163M

Recommended Posts

Ok, now we´re talking :)

Another batch of 36x300 secs frames out of the oven, this was captured in two consecutive nights with little moon impact so better contrast then my previous M42 image, also the callibration seem to be spot on as I can't detect any gradients or poorly calibrated residual glows, happy happy :)

Good to know there's still ample room for improvement as this is just over 3 hours so will add at least the double integration time, let's see what it brings.

Setup is the same:

 

-SW ED80 with Altair Astro 0.8X reducer (f/6)

-QHY163M

-Baader 7 nm filter

-EQ6 mount

-ASI 120MM with 50mm finger for guiding

Stack of 36x300 sec. at Gain20 Ofrfset100 USB traffic set to 5 (will lower to 1 on future captures to see if the amp glow is further reduced)

Hope you guys enjoy,

Great image, with lovely detail. What is causing the strange pattern around the bright stars? Is it some kind of diffraction or reflections?

Thanks!

The microlenses refrlections are a real pain unfortunatelly, this is caused by the sensor's coverglass as it has no a.r. coatings...I guess I could use some masks and try to minimize this issue a fair bit but it´s a lot of work, I wish that in a near future there will be some PS plug in to address this...just say´n... :)

Cheers,

      I've been processing this image for quite a long now.
      I started acquiring data the last season when I only managed to shoot 3 panels with the Canon 6D through the Esprit 80 for a total of ~7h.
      This season I restarted and I added more data and covered a wider area. So a mix of portrait and landscape panels were planned and shot with the same scope and camera. Now every pixel represents at least 3-4h of integration, some have more.
      All the above were shot from Bortle 2-3 sites where I traveled sometimes even for an hour of exposure.
      To the RGB data I added 17.5h of Ha, same story with the panels. Some were oriented N-S, others E-W. These were shot with the SW 72ED and the ASI1600 from home and Bortle ~7.
      Then I figured out I still had time and I planned and shot 9 more panels of luminance with the 72ED and ASI1600, each consisting of 1h of exposure.
      I combined all of these into an image, processed it and for the Orion nebula and Running Man nebula I also blended some data I shot last season with the 130PDS and ASI1600 from home.
      Below it's my first final version of all data combined. You can watch it in full resolution on astrobin: https://www.astrobin.com/full/jni0w8/ or Flickr: https://flic.kr/p/2iBGUXq

      Have decided to sell my trusty Equinox ED80 refractor.  Sharp optics, smooth two-speed Crayford rotatable focuser, fitted with a finder shoe, and complete with the original Skywatcher case and tripod-threaded mounting bracket.  A 3D-printed Bahtinov mask is included, along with a pair of mounting rings and a Losmandy dovetail plate.
      Collection preferred (Sussex coast, not far from Brighton), payment by bank transfer or cash on collection.
      Looking for £325.00

      I scrapped all the Oiii and Sii data I previously took during a full moon (about 15 hours worth) and retook it all when the moon was a bit smaller at 76%.  Ha was taken during 98% and 67% moon.  All the lights were taken on the following nights: 12th, 19th and 20th September 2019.
      Integration times, all in 600s subs unbinned:
      Ha = 28.33 hours
      Oiii= = 5.67 hours
      Sii = 5.67 hours
       
      The Ha data is really nice, and unsurprisingly the Oiii and Sii is not as strong (or nice).
      I'm missing that (vital) step in my processing routine of getting the Sii and Oiii properly stretched to match the Ha, before combining.  I dont really know how to deal with the weaker data properly.  Any pointers would be appreciated.
      What I do currently:
      All the data is loaded into APP into separate channels/sessions.
      The data is stacked and registered against the best Ha sub
      This produces individual stacks of Ha, Sii and Oiii that are all registered
      Each channel is processed with DPP in APP and then saved as a 16bit TIFF
      Each is opened in PS
      Stars removed with AA and any remnants removed and tidied up
      I then open a blank RGB document in PS
      I paste Ha into Green, Sii into Red and Oiii into Blue
      Adjust the selective colour settings to get 'Hubble palette'
      Adjust levels, curves, saturation until looks ok
      All the Ha Sii Oiii data is then combined together in a single 'super' stack in APP using quality weighted algorithm to create a 'luminance'
      That luminance layer is adjusted using levels, curves, and NC tools such as local contrast enhancement and deep space noise reduction (using masks to apply as required)
      The luminance is pasted onto the above colour layer, and incrementally added using gaussian blur
      Cropped and saved.
       
       
      Here it is anyway   I haven't intended on any more exposure time for this one, but will consider it, if the expert opinion dictates otherwise!

      My first relative success at this target.
      Some dust mites show because the mount had good tracking and I used no darks nor flats. With my camera the cure should be quite simply to power cycle off/on so that auto-cleaning moves the dust elsewhere.
      Capture: Olympus E-PL6 on Skywatcher 130PDS at 565mm/4.35 with SWCC and didymium filter on Omegon EQ-300 tracking RA
      Exposure: 12 × 60s × 2500iso
      Site: 50km from Paris (France), sky Bortle ~ 4
      Processing: Regim 3.4, Fotoxx 12.01+
