M3 – Globular Cluster

Messier object 3 is a beautiful globular cluster of some 500,000 stars. The picture below is one that I took late on the evening of 18th July ’07.

M3 is viewed in the constellation of Canes Venatici and is about 34 million light years from Earth. Despite its distance (further from us than our galaxy’s center) it still shines relatively brightly with an apparent magnitude of 6.2.

I currently use a range of software to process my images, with my aim being to maintain a scientifically accurate image that also conveys the beauty of our Universe. Whilst Registax is currently used for video processing & Deep Sky Stacker for quick & dirty stacks; I am growing to prefer Iris for more acccurate & critical work. It may not be the easiest program to learn but its results are excellent; a big thankyou to Christian Buil for his work developing the program. All that said, this image and the previously posted M51 image, were both processed with Iris before final adjustments in Adobe Photoshop & Lightroom.
