Build a Hinge Tracker for Astrophotography

Scorpius stars

This image of the Scorpius Milky Way was captured from Costa Rica with a DSLR camera and the simple hinge tracker mount described here.

If you have a DSLR camera and are interested in astronomy, you’ve probably considered dipping a toe into the astrophotography waters. But a camera is only part of the equation — for exposures longer than a few seconds, a tracking mount is usually necessary. Unfortunately, most suitable mounts are relatively bulky, or expensive, or both. But not the hinge tracker. It costs less than $10 to build, takes less than an evening to assemble, and requires no batteries. And best of all, you can put one together even if you’ve never built anything more complicated than Ikea furniture.

The Big Red One: My Optimized 6-inch f/9 Reflector

Big Red 6-inch f/9

Attention to detail is what separates a regular Newtonian reflector from one optimized for high-contrast performance. This 6-inch f/9 uses every trick in the ATM’s book to deliver superb planetary and deep-sky views.

This was the first telescope I made using my own optics. Like most telescope makers, I got started the easy way, by building Dobsonians with mirrors ground by others. But one day I got bit with the mirror-making bug. I blame my friend Lance Olkovick, our local club’s mirror-making ace. But why a long-focus 6-inch? At the time I was a hardcore Jupiter junkie and was convinced that a long-focus Newtonian would deliver excellent views of my favourite subject. I also wanted to prove a point.

My Photo Web Site

FilmAdvance title

I invite everyone to check out my web site,
In addition to astronomy, photography is a big passion of mine. So, I started as an outlet for my photographic explorations. There will inevitably by some astronomy related content posted there, but mostly it’s about seeing the universe through the lens of a camera, instead of the eyepiece of a telescope. Look in on it from time to time to see what I’ve been up to with my cameras and darkroom. Enjoy!

The Top 5 Comets of the Past 20 Years

Comet Hale-Bopp

Magnificent Comet Hale-Bopp on April 3, 1997. It is unquestionably one of the finest comets of the past two decades, but is it the best one of all?

Few celestial objects excite the imaginations of stargazers and the general public like a good comet. The recent apparition of Comet Lovejoy (C/2014 Q2) prompted me to reflect on the all the comets I’ve been fortunate enough to see in the past 20 years. There have been some stunners, some surprises, and a few that could have been great, but fell short. Here’s my (highly subjective) pick of the five most interesting and spectacular comets from the past two decades.

M11: Scutum’s Milky-Way Treasure

M11 finder chart

The Scutum Star Cloud and M11 are prime, dark-sky attractions.

Summer new Moons are what deep-sky observers live for. Overhead, the glowing band of the Milky Way stretches from horizon to horizon. There’s so much to see that it can be tough to choose! One area that I find particularly eye-catching is the Scutum Star Cloud.

Exploring Imbrium Debris

Daylight Moon

The Moon approaches first-quarter phase in a deep blue twilight sky.

When the Moon is nearly at first-quarter phase, the terminator sweeps across some of the most unusual lunar terrain. Aim your telescope toward the region lying between little Mare Vaporum, and the expanse of Mare Tranquillitatis. There you’ll find oddly furrowed features and a couple of badly beat up craters.
