Summer Astrophotography – A Passion Project

I love being a science communicator, being with people and sharing my knowledge of the universe. However, I have a personal fascination with the universe, and although this helps me learn more and ultimately makes me a better communicator, there is something nice about connecting with the stars in a traditional way, ie with a telescope. Every year, usually in Summer (a short season in Canada), I venture to a dark sky location and get in some observing, to remind me of the real universe that’s out there. Since I also love the visualization of space as a communication tool,...

Using Stellarium to Find Comet NEOWISE

It’s an amazing time to look up to the night sky! For the first time in nearly 6700 years, comet C/2020 F3 NEOWISE has made it’s return to the inner solar system. These small, icy, dirty clumps remain dim and dark through over 90% of their journey from the distant reaches of the Solar System, but once they close in on the immense heat of our nearest star, things change. Comet C/2020 F3 NEOWISE captured by the Parker Solar Probe as it swings around the Sun.

The Trials of Solar Eclipse Photography

Although the August 21st eclipse happened about 6 weeks ago, I realized it would take me a long time to edit all the photos I took during my trip.  I had over 2000 individual shots of the eclipse alone, taking a single (1/4000 s) shot every 10 seconds, at ISO 100, with my telescope coming out at around f/6.  I’ve done a lot of time-lapse photography before, so I thought it would be a routine shot, but I was wrong.  Eclipses are much tougher to edit in terms of a time-lapse. But first, the end result of my 10 hours...

Always an Eclipse Somewhere

As I often do, I pulled up the Astronomy Picture of the Day, and noticed today’s photo was a fond reminder of the eclipse I witnessed a month ago. I began to think about the preparation and timing, planning and organizing, the countless hours of testing gear for a single moment lasting two minutes, where the Moon and Sun aligned.  I was in the right place, at the right time. Solar Eclipses are rare, and it’s mostly because only a narrow band of land on Earth, usually around 100 Km wide, experiences such an event at any one time.  And with...

Cassini – A Fond Farewell

I remember vividly my first astronomy class in university.  Winter 2004, only months before the Cassini spacecraft was set to arrive at Saturn after a seven year journey.  On several occasions in that class we talked about what we might see when Cassini reached it’s destination.  The first dedicated mission to the jewel of the solar system, originally conceived right after the voyager flyby in 1982, would give us a chance to study more than just a planet, but an entire system of interaction between a planet and it’s moons.  Beyond that, it included the Huygens probe, to land at...

Astrophoto Bucket List

After the eclipse on August 21st, I took a deep breath.  I spent a year focussed on photographing the eclipse, and with that goal complete, what was next?  I was in the plateau of the Grand Teton National Park in Wyoming, a couple dozen miles from Yellowstone, and had three days to enjoy with my fiancee.  As luck would have it, those days were absent of any clouds, giving me two perfect evenings in clear, dark, dry skies to do some of the best astrophotography of my life.  Here’s what I shot. The milky way shot for me is a...

Motivation Monday: Tree Branches of Choice

A tree is a good way to represent a series of decisions.  Start at the trunk and move to smaller and smaller branches, each branch tip representing one o the many possibilities.  A tree representing a persons life would be immense, far larger than any tree on Earth.  There are an incredible number of possibilities that arise due to a persons choices, and every waking moment we move along a path.  But there is one stark difference between this tree and a real tree.  With the decision tree, you can cross back over to other paths. I started thinking about this...

Astrophotography: Sagittarius and the Galaxy

The challenge of learning astrophotography, and photography in general, is two-fold.  There’s the work you do at the eyepiece, requiring you to choose the right settings for the right shot.  Then there’s the work you do at the computer screen, the post-processing and adjustments.  Ultimately the more important one is the camera work.  If you take a bad photograph, no amount of post-processing will help you, even if you are an expert at it.  It’s like the image is the cake, and the processing is the icing.  No matter how much icing you cover it with, a bad cake is...

Astrophotography: First go at Luna

The Spring has been a bit slower than I would have liked in terms of astrophotography.  I have seen a lot of fantastically clear evenings, but have been plagued by a lack of time and a few technical issues that have kept me from getting the many hours of practice needed to become competent.  I did manage to purchase an inexpensive adapter to use my camera with my telescope, giving me a ton of new options for photography, as well as a ton of new challenges. The two main problems I had, and need to address in the future, are...

Relative Time: Photography Year 2

Last year after getting a Canon DSLR camera, I spent as much time as I could doing some basic astrophotography.  I took photos of stars, planets, the Moon, and even did some star trails.  One thing I quickly realized is that there are limitations if you don’t have a tracking mount or a telescope adaptor.  The tracking gives you a method for taking longer exposures, and the telescope adaptor as expected gives you the ability to zoom in on distant objects. Even with these temporary limitations (I hope to invest in them someday) there are still a lot of options...
