IC4628 – Prawn Nebula

ic4628

  • Taken on 06/08/2014 – Moon was about 70% illuminated.
  • Ten 5 minute exposures
  • ISO800
  • Skywatcher HEQ5PRO Mount
  • GSO 8″ Newtonian f/5
  • Canon 450d w/ IR filter removed, GSO Coma Corrector
  • Orion Starshoot autoguider
  • BackyardEOS to control the DSLR
  • PHD2 to handle autoguiding
  • Dithering switched on in BYE

Initial registration and stacking was handled by DeepSkyStacker. After that I saved the image as a TIF and imported that into PixInsight. All of the post processing was done in PixInsight – I really need to use it more, the results are worth the effort!

On the higher resolution image the focus looks a little off. I suspect the focus may have shifted slightly due to the dropping temperatures, or I just did a bad job of getting the image into focus.
