M1 Crab nebula in narrowband

Recommended Posts

Still dipping my toes into narrowband imaging I decided to have a go a the crab nebula. Processing is done in a sort of Hubble palette with 15x10 min Ha as green, 16x10 min SII as red and 17x10 min OIII as blue. All binned 2x2 and imaged with an Atik 460 in an Orion AG12. Curves, levels, a little sharpening of the nebula and some colour adjustment.

Hi Lars,thats amazing,fantastic image.

I notice you have binned each Filter at 2x2,was that to get more signal,and less noise.

Did you resize the completed picture afterwards.

Well done.

Mick.

Thanks all for your comments!

Mick, the reason for binning the image was simply to get more signal in a short time since the weather here in Sweden has not been promoting astroimaging in any way this autumn.

For this picture, the intention was actually not to bin Ha, but that night the seeing was so bad that I decided to bin it anyway since there would be no advantage of a higher resolution

Simon, I could make a center crop but to be honest, it would only look fuzzier since it is already at 100% resolution.

This looks like a good technique, I see lots of fine detail in there. Great image.

      Selling my full narrowband set up for multiple reasons: I could do with the money and mono just isn't really doing it for me.
      £1000
      Includes:
      Altair Astro 183m Tec
      Baader Narrowband filters (Ha, OIII, SII and Clear)
      ZWO Electronic Mini Filter Wheel
      All associated cables/plugs
      T2 extensions to reach 55mm back focus for use with reducers
      Boxes and cases
      There is a scratch on the T2-T2 adaptor for the filter wheel and a couple of the labels on the filter boxes have been torn. But otherwise the important parts work perfectly well.
      Collection or postage via DPD.
      Buyer to pay postage and PayPal fees.
      No offers currently accepted, and I would rather not split

      Hifolks,
      Here's my take on IC1396, let me know what you think.
      In total 7.5 hours exposure time using narrowband Ha, Sii, Oiii.
      Post processing in photoshop and lightroom.
       
      Thanks for watching, clear skies!

      THIS ITEM HAS NOW BEEN SOLD.
      This listing is for my personal narrowband filters (Kayron from Light Vortex Astronomy). They are the Astrodon Hydrogen-Alpha (HA), Oxygen-III (OIII) and Sulphur-II (SII) 3nm 1.25" narrowband set. These are considered the highest-end narrowband filters money can buy, able to produce images of exceptional quality and incredible sharpness, cutting through a vast amount of light pollution. The 3nm variants featured here are fantastic for pulling out fine nebulous structures clearly above background. For more information, please see Astrodon's website:
      https://astrodon.com/products/astrodon-narrowband-filters/
      Please note that these three filters together currently retail at just over £1,710 from UK suppliers, €2,180 from European suppliers or $1,690 from US suppliers. Payment is preferred via bank transfer but PayPal is OK with an extra 2.9% to cover PayPal fees. I'll cover postage to you via tracked Courier. 
      I welcome any questions you may have regarding this listing. Thank you for looking.

      The bubble nebula. Not much to add about the target itself as it is already popular enough.
      A combination of HOO shot with the ASI1600MMC + Astronomik narrowband filters through the 200mm newtonian tube removed from the dobson base and put on the EQ6-R.
      About 6h of exposure through the Oxygen filter and about 9h through the Hydrogen filter.
      Clicking on the pictures will redirect to the astrobin images where you can watch them in full resolution.
      Crop close-up

      And widefield

       
      Thanks for watching and clear skies to you too!
      Alex
