A striking photo of the Crab Nebula

A stunning and beautiful image of the Crab Nebula. Uploaded by Arpingstone, it and a smaller resolution version (Image:Crab.nebula.arp.750pix.jpg) are used in a variety of articles.

Support. Stunning indeed. - Mgm|^(talk) 09:22, 12 December 2005 (UTC)[reply]
Oppose. Like for Mandelbrot sets, I think for space photos we need to set a high bar due to the large number of potential candidates. This one isn't quite geometrically pleasing, and I'm not too excited about the colours towards the middle of the image (a bit washed out?). Enochlau 22:23, 12 December 2005 (UTC)[reply]
( + ) Support I really like space photos like this. --Fir0002 07:47, 13 December 2005 (UTC)[reply]
Oppose - Per Enochlau, so many great space photos. This one gets owned by the Horsehead Nebula in my opinion. - Hahnchen 01:25, 14 December 2005 (UTC)[reply]
Oppose There are so many more more visually pleasing nebula images than this. D e nni ☯ 02:47, 14 December 2005 (UTC)[reply]

Question Are images of nebula colorized (they must be, right?). Do the colors correspond to anything in particular? ~MDD4696 (talk • contribs) 03:04, 15 December 2005 (UTC)[reply]
- Answer: Not necessarily "colorized". but they are not always in "natural" colors, either. Such images are taken, through a telescope, with three successive exposures, and each exposure is through a different colored filter. The exposures can be in visible light, but also ultraviolet and infrared. When these exposures are added together for the final picture, each one is given one of the primary colors, thus creating a full-color image. If the shots were not through visible light filters, the final colors are not "natural". Nowadays, this all is often done with CCD chips and computers. Also note that you cannot see much color if you look through a telescope, since the human eye is almost color-blind in very low light. --Janke | Talk 06:58, 16 December 2005 (UTC)[reply]

Oppose, agree with Enochlau on setting the bar higher for space pics. --Dschwen 10:47, 20 December 2005 (UTC)[reply]
