This is my first issue as the magazine’s editor, having taken over the position from Terence Dickinson. It’s a great honour, and Terry has been a tremendous friend helping make the transition remarkably smooth. As I note in my editorial, he will be contributing his new column, Cosmic Musings, starting next issue.
In spite of my expanded editorial duties, I’ll be continuing my regular On the Moon column. In this instalment I talk about the May Blue Moon. Don’t be surprised though if you’re unaware of it — it’s a “seasonal” blue Moon.

This weekend features moonfree evenings — perfect for enjoying some deep-sky treasures. Spring is best known for the rich galaxy fields found in Leo and Virgo, but in addition this is the season when M44 is well placed in the evening sky. Continue reading “Weekend Stargazer: April 29 – May 1”
Over the years I’ve tested virtually every affordable image-stabilized binocular on the market for reviews appearing in Sky & Telescope magazine. Canon is the clear leader where astronomy is concerned. The company currently offers six models, each with something to interest the backyard stargazer. Some of these binoculars are among the very best available for astronomy, while some are more general purpose. Continue reading “Review: Canon’s Image-Stabilized Binoculars”
For optimum performance, precisely aligned optics are a must. Luckily, achieving this goal doesn’t have to be difficult.
Most telescope users know that the only way to get every last drop of performance from a reflector telescope is to ensure that the optics are in good collimation. Here’s a method that’s simple and doesn’t require tools or even a centre-dotted primary mirror. Continue reading “No-Tools Telescope Collimation”
The Newtonian reflector is one of the most versatile optical configurations ever created. Whether homebuilt or commercially manufactured, a good Newtonian can rival the performance of any optical design.

When I was preparing to travel to Australia for a total solar eclipse and some dark-sky observing sessions in the Outback, I decided it was finally time to rebuild my 8-inch travelscope so that it could go into my suitcase and arrive safely at my destination.

Binocular stargazing is full of surprises. Sometimes you stumble across a pretty cluster and wonder how you’d previously missed it. Other times, you hunt and hunt for a galaxy listed at 8th magnitude, only to come up empty handed. It’s enough to make you wonder — what makes one object a binocular standout and another difficult challenge? Compiled here are the five most important factors that determine whether or not a deep-sky wonder will turn out to be binocular trash or treasure.

Requiring only a few parts, this simple and effective setup provides stable images for detailed views of the night sky.
“This is the best binocular mount I’ve ever used!”
Those were the first words out of my mouth as I came indoors from testing my just-completed binocular rig. It’s rare that I build something that actually works better than expected, but finally I’d come up with a binocular mount that provides steady views, is easy to use, very portable, and simple to build. It was a good night. Continue reading “Build This Simple Binocular Mount”
I’ve been building and using telescopes for more than three decades and I’ll share with you a secret: collimating a Newtonian reflector is easy. So why does it seem so difficult when you’re just starting out? Probably because you’ve done your homework by Googling the subject and have read and re-read everything you’ve found. And now, you’re lost in a forest of information — some of it contradictory, some of it densely technical. Truly, sometimes less is more. Continue reading “A Beginner’s Guide to Collimation”
