Crab spiced up with POSS2

Recommended Posts

Here is the crab nebula with my RGB data from two nights ago. That was a night that allowed 1.5 hours of data before the moon and mist sent me to bed. To this I added monochrome data (red filtered) from a glass plate taken during the 1990ties Palomar Observatory Sky Survey (put in as luminosity). So, a mix spanning about 20 years. My data was taken with a 5 " ES apo and Canon 60Da (15 x 6 min, ISO1600 naturally chilled by the ambient -7°C). All done in PS CS5. For anyone interested in spicing up their RGB data, POSS2 data can be downloaded from:

Here is first the final product with a zoom in showing some detail. I also post my RGB (I am sure I could do better with more time and less mist) and the POSS2 data.

Comments most welcome.

After looking at other crabs on the net, I realized that I could probably also try some more deconvolution and sharpening on this one, so here is a sharper version.

Comments and suggestions of course welcome!

      The Crab Nebula (also known as M1, NGC 1952 or Taurus A). This is quite an improvement on the last attempt at imaging M1 about two years ago. This time it was possible to bring out some of the filaments that make this object so interesting - this despite using a much shorter focal length making the object appear significantly smaller. The image is cropped rather radically to show more details in the nebula so the stars appear bigger than I would prefer, but on the original they look fine.

      Hi all, here is my first image for this website and first challenge here

      M1 (Crab Nebula) - SNR in Taurus
      Narrowband image (Ha - 3 hours, OIII - 3 hours, SII - 3 hours)
      Taken with GSO RC 6" + ZWO ASI1600MM with ZWO EFW + Optolong NB filters.

      Thank you

      My first attempt at the Crab Nebula (M1). The cropped image is a LRGB with Ha blended into the Lum and Red channels and represents about 14 hours integration. I was quite pleased with the amount of detail revealed. 
      LIGHTS: L:14,R:16, G:8, B:14 x 600s, H:11 x 1800s. DARKS:30, BIAS:100, FLATS: 40.
