About

Hello and welcome to my website! I started deepskies.com back in 1998 as a way for me to share my love of astronomy with the Internet. Over the years, the site has gone through many evolutions; from being a repository of my own telescope reviews, to being a news source of happenings in astronomy and at one point I envisioned a deep-sky image gallery. That is the theme that I've decided to return to with this latest edition of the website. It will focus on images of deep-sky objects, all presented in a common format in such a way that the size of the different objects can be directly compared. I'm excited to return to this project that I started back in 2013 (ten years ago!). I have also carried over some of my more frequently visited pages (ie: my DeepSkies Atlas, and the Meade LX Registry) and I've moved any other content over to my personal website: www.ricktowns.com.

Who is Rick Towns?

I am an amateur astronomer and professional computer programmer / systems analyst living in central Canada. I am married with three grown up children and a dog. My hobbies include astronomy (of course!), photography, mountain biking, computer programming, playing guitar, ham radio, hiking, and retro computing. My career highlights include working for Microsoft and NASA. If you want to get a hold of me, here's are some spots:
