Comet 17P/Holmes

Comet 17P/Holmes (leveled to bring out detail) on 10/26/07

There she is – my first comet photo. This image is taken using my Meade DSI Color on my 4.5in (114mm) telescope. It is 100 stacked 2 second exposures. The comet is so bright that if I take any longer exposures than 2 seconds with my camera, it maxes it out and I lose detail.

Tonight is perfect for stargazing and this new comet is easily visible both to the naked eye as well as through my telescope. In my scope and binoculars, it has a bit more of a gold cast to it, but this image seems a bit blue. I’m not sure why that is. In the image above, I’ve messed with the levels a bit to bring out the secondary coma area. Below is the image without the leveling. You can still see the wider coma, but it’s fainter. Anyway – it’s beautiful and I’d strongly recommend that if you haven’t already done so that you go outside and look at it, particularly through binoculars or a telescope.

  1. Great photos! I saw the comet last night and tonight. Great view through binoculars.

    I edit the nonprofit THE CITIZEN SCIENTIST for the Society for Amateur Scientists at http://www.sas.org/tcs/. May we use one of your photos in a short announcement with a link to your site and full credit to you?
