M27 - and first light Atik 460EX mono

Recommended Posts

Derek, with yur newt, you'll have dirty big vanes holding teh secondary mirror in place giving yoru spikes ;-)

Today I have taken a 'brave pill' & have whipped off the front lens cell off my scope. Planning on giving it a gentle clean front & rear.

There is no sign of anything in the light path like a spiders thread or hair or anything......I'm puzzled. the only thing is can be is debris on the lens cell, which I know is far from clear. Hopefully a clean will resolve the issue.

Hope I can get it all back together okay ;-)

      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!

      Taken on Sunday evening with a 98% Moon.
      Comprising of 12 x 600s subs using an ED80 with a 0.85x FF, an Atik 383L+ and a 7nm Optolong Filter.
      Stacked in DSS, and processed in PS.
       
      Full frame and cropped, mono and h-alpha colour using NC Actions.
       
      Thanks for looking
      Adam.

      Hi all
      This one was processed using Ha as monochrome Luminance layer.
      Ha 2x15m 2x10m 31x5m, binx1, 3h25m integration time
      RGB 5x5m each, bin1, 1h15m integration time, altogether 4h40m.
