NGC 281 new
      #5534729 - 11/23/12 01:39 AM

NGC 281 in Cassiopeia. Captured with an SV85s and a modified Canon 350D from my light polluted (red zone) back yard. No filters were used. ISO 800, 15 x 6 minutes. Processed with Pixinsight.



Those dark areas are Bok globules that can seed star formation. Hope to redo this from a dark spot with a CCD some day.

Larger version here.

Good looking Pacman; I had to process mine... a few times to get all the nebulosity. Thx

Thank you Mike. It was a little tricky to process at this scale. There's nebulosity and dust all over. Gradient subtraction and color balancing steps were a little challenging because areas of true background are small.

Great shot for a light polluted area. You caught a lot of nebulocity there.

Beautiful. I like the red color a lot in your shot.

Those Bok globules (HII) are named after the Dutch/ American discoverer Bart Jan Bok. Bok is the dutch word for a male goat...

To look at the photo one would have never thought you were plagued with LP. Nice processing of an iconic object!

Cheers,
Ed

Thank you Traveler, Ed and Gary.

PI was very useful tool in removing some nasty gradients and for the color calibration.
