A New Year, a New Night-Time Photography Class!

I’m happy to report that Royal Botanical Gardens has asked me to lead another Night-Time Photography class! If we get sufficient response, we’ll start at 7 PM on the evening of Thursday 26 January 2017, at RBG’s Nature Interpretive Centre. The class will run for a total of four sessions, weekly.

The class will be a hands-on opportunity to take photos at night, with an emphasis on capturing beautiful images of the sky. We’ll cover equipment, celestial objects, post-photography processing, and more. This isn’t an astronomy class per se, but we will talk a bit about astronomy. By the end of the course I am hoping everyone will feel confident going out at night with their cameras and experimenting with capturing beautiful images.

We’ll try to end each two hour classroom experience with a quick dash outside to see be seen. Guidance will also be given on photo opportunities taking place between classes.

RBG’s public program calendar is available on-line at: http://www.rbg.ca/files/pdf/education/publicPrograms/RBGexperiences1116.pdf

You can register on-line for any of the RBG programs at: https://tickets.rbg.ca/PEO/

To find the Night-Time Photography course, just click 26 January 2017 on the calendar on the web site. Registration is limited to 20.

If you are planning to take the course, please contact me ahead of time for more information. It’s recommended that participants bring their digital cameras and tripods to the first class. Digital cameras should be able to be operated completely manually. A wide-angle lens is best for this sort of photography. Tripods should be very sturdy. I can make recommendations if anyone has any questions.

Working On The Details

The perigee moon of November 2016 once again found me out with a camera. I took frames to make this image at Spencer Smith Park in Burlington, Ontario. 


I was very pleased that SkyNews Magazine selected this as their Image of the Week coming out of the Perigee Moon event. 

In the coming days I intend to post a detailed “how this was done” column. 

Hail and Farewell Geoff Gaherty

Astronomy in Canada has lost one of its most interesting voices. Dr. Geoff Gaherty, of Coldwater, Ontario, passed away on Thursday 7 July 2016 of complications following surgery.

I’d known Geoff since about 1992. During my post-doctoral work at the University of Kent at Canterbury, England, I was invited to come to Canada and consider taking up the post of Executive Director and Curator of the Centre for Endangered Reptiles. This was a non-profit conservation breeding and research centre founded by Geoff. He was a many of many interests. In my time with the CER from 1993 to 1995, he was always helpful, interested, and a lot of fun to talk to. A true gentleman with a lot of interests and skills.

As an amateur astronomer Geoff was extremely active in the Royal Astronomical Society of Canada. He wrote for the highly-regarded RASC Observer’s Handbook, and he maintained his own blog and social media outlets for information for astronomers.

I’m very saddened by Geoff’s passing and wish the very best to his wife Louise and son David. Ad Astra, my friend.

Spotting Pluto From Down Here

As NASA’s New Horizons speeds through the Pluto system this July, it’s tempting to take a look into the sky from earth and think of what’s unfolding billions of kilometers away. The question is, where can you turn your gaze from earth and at least be pointing in the approximate direction?

Pluto is so far from earth that it does not change its position in the sky very quickly. At the present time (writing on 13 July 2015), Pluto is in the general area of the constellation Sagittarius. It’s not far from a famous asterism, the Teapot, that lies just off of the main band of the Milky Way.

The attached image was created by making a screen capture from Stellarium, set for the location of Hamilton, Ontaro, Canada, at the time when Pluto is highest above the horizon on the day following the close encounter on the 14th of July. This turns out to be at about 1 PM DST on the morning of Tuesday 15 July 2015. At that moment Pluto will be about due south and 25 degrees above the horizon.

From Hamilton, Ontario, on the day of the close encounter, Pluto will be rising at about 8 PM and will set the next day (the 15th) at about 5 AM. It’s extremely faint, of course. It will be extincted to a magnitude of about 14.5 on the 15th at its highest elevation.

The weather forecast for the 14th for the Hamilton area is for cloud and rain. In order to try to get a memento image, I have programmed one of the Sierra Stars Observatory Network telescopes to try to photograph the dwarf planet.

Happy Birthday Carl Sagan

Carl Sagan was a towering figure in science. He was born on November 9, 1934, in Brooklyn, New York, and died following a long battle with cancer on December 20, 1996, in Seattle, Washington. In between, in just 62 years, he reshaped public understanding of physics, astronomy, and space exploration. More than this, he was a leader in exploration and discovery, involved in many of the scientific teams behind truly ground-breaking space missions in the 1960s and 1970s, including the Apollo moon landings and the Viking missions to Mars.

I first started to encounter Carl Sagan as a popularizer of science while an undergraduate at University of Guelph, and wrote a couple of columns mentioning him for The Ontarion, the university’s newspaper, in the early 1980s. I briefly thought of pursuing grad work on exobiology but ended up continuing along with evolutionary ecology instead, at Guelph for a few more years. His influences are still all around us.

Planning my 2015 Calendar

It’s still just in the concept stage, but I’m thinking of producing a calendar form 2015 of photos of the moon that I’ve taken over the past several years. Other things would be in there too. I’ve done my own calendars of other photographic subjects in 2012 and 2013, and in 2014 two of my photos were selected for inclusion in the Hamilton Amateur Astronomer’s calendar. I think I have enough material for an interesting moon calendar this year! Here’s a concept for the cover.

Some Coming Attractions: two comets and a dwarf planet

It’s been a while since I put a post together. I thought some of the space exploration highlights to come were worth a note, so here are a few I’m watching develop.

In August of 2014 we’ll be treated to something pretty exciting: a spacecraft is due to go into orbit around a comet. The European Space Agency’s “Rosetta” probe has already done amazing things flying past two asteroids. In August it will be lined up to be captured by the feeble gravity of comet 67P/Churyumov–Gerasimenko. After several weeks of distance observations, the probe will release a little lander named Philae that should touch down on the comet in November.

This October there will be a real “nail-biter” in orbit over Mars. A comet discovered last year by an observatory in Australia, called C/2013 A1 Siding Spring, will come no where near the earth. However, on 1 October it will swing past Mars – very close to Mars, in fact. Mars is, of course, being closely observed by all sorts of spacecraft. NASA currently has two orbiters in action around the Red Planet, and another is on the way. Comets have been described as “dirty snowballs” and this one is expected to be shedding little chunks of rocky dust as it swings past Mars, exposing the spacecraft from earth to a concentrated rain of debris travelling multiple miles per second.  Spacecraft controllers have been working hard to keep their charges safe – but it’s uncharted territory.

In a year’s time, NASA’s New Horizons spacecraft will make the first close-up recognizance of Pluto. Whether or not you like to think of Pluto as a small planet or a very large Kuiper Belt Object, it’s fascinating territory and the last major body within the “inner” Solar System to have that we’ve never seen close up.
