In modern astronomy, the images produced by a telescope are black and white. So how do astronomers put together the amazing colour images that we see?
Here is your chance to find out, and to assemble an image yourself!
What You'll NeedThe instructions provided here will teach you everything you need to know in order to create your very own image of The Glowing Eye Nebula (a.k.a. NGC 6751). The Glowing Eye Nebula was the winning target in the 2009 Australian Gemini School Astronomy Contest.
In order to create your image, you'll need to download:show us the results!
software you'll be using: Gemini Observatory in Chile. Gemini has primary mirror that is 8 metres in diameter, and the digital images produced by Gemini's GMOS instrument are each about 7 megapixels in size.
You can choose between datasets:
- 2009's Glowing Eye Nebula (recommended starting point) [80MB ZIP].
- 2010's NGC 6872 and IC 4970 [74MB ZIP].
- 2011's NGC 7552 [107MB ZIP].
- 2013's Gum 85 (amateur division) [32MB ZIP, TIF only].
- 2013's IC 5332 (student division) [28MB ZIP, TIF only].
- the Adobe Photoshop or Photoshop Elements programs,
- or the (freely available) GIMP, the GNU Image Manipulation Program.
In addition, you can have even more control over the process if you download the (free) FITS Liberator program.
Whether you're using Photoshop or GIMP, be sure to download the appropriate tutorial.
