Update on Joly Astronomy

Hi Everyone,

I hope you are all well!

School, Work, and other priorities started to take over, and I neglected to update my blog regularly. For that, I am sorry!

Moving forward, I will continue to make posts on this website. However, I will post it at my own discretion.

I will no longer post about upcoming astronomical events. For those who found it useful, I’m happy to hear that it helps, but other priorities have kept me from regularly posting monthly astronomical events. You can find the astronomical events for 2016 here.

Other than that, I will continue to write about the night sky, space missions, and other topics that catch my eye.

Lastly, this past December 19, 2015, was the second anniversary of the start of my blog! Thank You for everyone who has followed my blog throughout the past two years. I hope to see you all here in 2016!


Here are some images I would like to share.


June 7 gave me a fantastic opportunity, albeit a difficult challenge. The International Space Station (ISS) was going to streak through the Toronto sky after dusk. After a few failed attempts, I decided to try and get the ISS again. To increase the challenge further, I decided to use the CCD camera to get a closer look. After I got the video, I was relieved it was done but was left wondering what the result was. There were over 10,000 frames of nothing, 200 frames of trailing ISS, but I got 5 good frames of the ISS out of it. Here is one of them:


The ISS. The image is cropped. (I’m very proud of this picture!)









On June 21, I hosted my first workshop. a little more than 10 people came to the workshop, where we covered Startrails, Astrophotography with DSLR and CCD cameras, etc… It was a great success. Many of the participants enjoyed the workshop and went home with amazing startrails images. I also tried to take some Milky Way shots from here. Little did I know that the Galactic centre was below the tree line. Next time!


20″ exposure, f/4, ISO-800

On June 24, I took out a borrowed 127 mm Achromatic Refractor to image the Moon with. It was an interesting experience. The pictures look good, and I was impressed with the image that the Refractor produced. The result is below:


1/40″ exposure, f/6.5, ISO-100 (Note: The Moon is flipped upside down.)

On that same night, I also went out to Glen Major Forest and took a Startrails image. It lasted for an hour, and compared with my first ever startrails from Glen Major, it had longer startrails and more ground. It is a good image. While I was imaging it, there were other people there having a good time, and I was worried that some car light from them would wreck the image. Thankfully, none of their lights ruined on my image, and I came home with a good set of images to stack. The result is below:


162 frames, 30.5″ exposure, f/4.5, ISO-1600

On June 29, the day before I returned the refractor, and the day before the Venus-Jupiter conjunction, I learned that tomorrow would be cloudy. June 29 had cloud cover on it, but it wasn’t so bad. I could still see Venus and Jupiter. Therefore, I rushed back home and brought out the refractor. While I was observing the two planets, I noticed that Venus and Jupiter had some fringing on it, much like my Canon lenses, when aimed at the Moon. It was annoying to see that, but I found a solution to it. After taking many pictures, and being eaten alive by mosquitoes, I went back inside and rested. The resulting image is below: It’s amazing how close the two planets got. It got closer last year, but I was very impressed by this grouping of two planets.

In July and August, I led two different workshops hosted by the Creative Photographers Markham. There, everyone took their own startrails images and had a grand time imaging the night sky. I also tried to take my own timelapse that night. However, it was a very humid night, which led to dew accumulating on my lens. By the end of the timelapse, the image became very blurred and very foggy. It was disappointing, but it was a lesson learned.

On September 27, 2015, the last Lunar Eclipse in the tetrad was to occur. I also planned the last workshop to occur that night. However, there was clearly going to be clouds in the sky, which was disappointing. We had a rough start, but many people came to the workshop and we were lucky enough to have a break in the clouds and we were able to see the lunar eclipse for a short period of time. We all had a great time, and got great pictures!

On the latter part of 2015, I was able to take this picture of the Lunar X. This feature is visible every lunar cycle for only a few minutes when the light hits the moon just right. The angle of the light shapes the craters like an X.


I hope to see you all again!

What I’ve Been Up To

Hi Everyone,

Notwithstanding my update for June’s astronomical events, I’ve been absent for the whole month of May. That is because it’s been a busy month for me. Here’s a bit of an update of what I’ve been up to from April 22 to now.

On April 22, 2015, I delivered my presentation about my experience as an amateur astronomer that day. Throughout the presentation, I talked about the photos I took, honestly, and with a little bit of humour. It was well received by the audience.  I hope to follow that up with another presentation a few years down the line.

On April 28, 2015, I discovered the wonders of BackyardEOS. It’s a program that uses your DSLR camera like a CCD Camera. It was really effective as an imaging device, and as a focusing device. I got a few pictures like this using BackyardEOS.


On May 8, 2015, It was a clear night, and I felt like taking another startrails image. Therefore, I made another startrails image from my backyard. I used over 700 frames, 5”, f/4.5, ISO-800. It turned out really well.


From May 20-24, 2015, I had the opportunity to volunteer for the International Space Development Conference (ISDC). It was a great experience as I made met many heavyweights in the aerospace industry, gained valuable experience, and made many new friends. I had a great time. In addition, I was able to get this startrails image from the heart of downtown Toronto. I took over 1043 frames to get this image. Each frame were 3” exposure, f/5.6, ISO-1600. It was a long image, but it was worth it. Next year’s ISDC will take place in Puerto Rico. Who knows, maybe I’ll be there…


This image was a difficult one to capture. I needed to balance how much light I would capture, while still capturing the movement of the stars. Too much exposure captured the light pollution of the city. Too little and the stars won’t show up. That’s why I chose 3″ exposure, because it wouldn’t capture too much light, while still capture the stars. f/5.6 to reduce the amount of light pollution captured, and ISO-1600 because we need to capture enough light.


That is what I’ve been up to these days. Thank You for everyone’s support. Sorry for the sporadic blog posts. Keep looking up, you never know what you’ll find up there.
