To mark the occasion of 30 years since the Canada-France-Hawaii Telescope saw 'first light', a 370-megapixel deep sky image containing half a million galaxies has been released.

The image – CFHT Legacy Survey Deep Field #1 – was made by accumulating hundreds of hours worth of light integration over five years using the 340-megapixel camera MegaCam. Stacking the images together reveals an ultra-deep view of some half a million distant galaxies, along with a few foreground stars from our own Galaxy. Ultra-deep views like this can be used to probe the most distant galaxies, quasars and gravitational lensing effects.

The new image is far too large to display on a computer screen, so CFHT has created a zoomable image. The image published here shows the whole view which is nearly 20,000 square pixels. Zooming in reveals the glorious detail captured in the survey; the inset is an image 500x500 pixels and makes up 0.07 percent of the whole image. You can navigate the whole region here.

The CFHT is a 3.6 metre optical/infrared telescope and is located at the summit of Mauna Kea in Hawaii. It has been operational since 1979.

This special publication features the photography of British astro-imager Nik Szymanek and covers a range of photographic methods from basic to advanced. Beautiful pictures of the night sky can be obtained with a simple camera and tripod before tackling more difficult projects, such as guided astrophotography through the telescope and CCD imaging.
