M1, the Crab Nebula.  A Supernova Remnant

M1 is the remnant of a supernova explosion that was observed by Chinese astronomers in 1054, so the remnants have been expanding into space for almost a thousand years.

	This is my first attempt at this nebula.  It is magnitude 8.4 with a surface brightness of 11.0. Date and Time: 7th January 2007 21:39 UT Camera: Atik ATK1 HS Telescope: LX200 with 0.33 focal reducer (focal length 800 mm) Capture: K3CCDTools. Low gamma, exposure 10 sec, 100% gain, 79 frames Processing: K3CCDTools. 34 frames stacked.   Registax. wavelets 2-4 = 10, gamma curve   PhotoImpact. Brightness -39
	Here is M1 in its setting in the sky.  It was taken with my 135 mm SLR lens.  If you move your mouse ovrer the image you will see some of the stars identified with their magnitudes and also, to give it scale, an image of the full Moon taken with the same optics. Date and Time: 20th February 2010 19:12 to 20:51 UT Camera: Starlight Xpress MX716 Telescope: 135 mm SLR lens Capture: Star_mx7. Exposure 60 sec, 88 frames Processing: Star_mx7. Background, non-linear stretch (factor 25), background.  Registax5. 74 frames stacked, wavelets 1-2 = 5, gamma 1.4, histogram 12-255
