About this time last year, I was preparing some of my first astrophotography prints for the Square Foot Show at the Owen Sound Artists’ Co-op.

After one of my prints sold last summer, I got a call during our family camping trip asking if I’d like to join as a temporary member. Of course, my answer was yes.

To my surprise, they weren’t sick of me yet 😉 and extended my temporary membership. Then, in February of this year, I was offered full membership, which I happily accepted.

Now, I’m very pleased to announce that I’ll be joining the board of directors for the Owen Sound Artists' Co-op! A great community of talented folks, and I’m really looking forward to being more involved.

See y’all tonight at the AGM! 😁

My latest capture, the Leo Triplet 🔭

I imaged the Leo Triplet back in 2024 with my 80mm APO, but it was nice to revisit this target with a little more reach.

The Leo Triplet is a group of three prominent galaxies located approximately 35 million light-years away in the constellation Leo. Messier 65 and Messier 66 are both intermediate spiral galaxies discovered by Charles Messier in 1780. NGC 3628, also known as the Hamburger Galaxy, is an edge-on spiral galaxy discovered by William Herschel in 1784.

This is 10.5 hours in LRGB, taken with my ASI 1600MM-C, using my 6” RC and a 0.67 reducer at 0.74× reduction.

I think I've found the perfect place to hang my 'Summer of 69' piece by William Van Veen – right next to my scopes!

I had to snag this from the Owen Sound Artists' Co-op before someone else beat me to it. 😁

M81, M82, and the Not-Yet-Visible Vulcan
4-Panel Mosaic

This will be an ongoing project, but I wanted to check my initial framing after the first night out, and figured I’d share a look at how the mosaic is coming together.

This is just 24 minutes of luminance for each panel so far, but I’ll be collecting many hours of LRGB, along with even more hydrogen and oxygen data to help bring out the Vulcan Nebula.

Clear skies! 🔭

It was great to finally get back out for some imaging last night 😊
My first couple of projects this galaxy season include a 4-panel mosaic of Bode's, Cigar, and Vulcan with the 80mm APO, and the Leo Triplet with the 6" RC.
Here’s a peek at the luminance data of the Leo Triplet from last night.
Looks like we may have some more clear nights soon🤞

Just added a few new prints at the Owen Sound Artists' Co-op 😁
Swing by, say hi, and see what’s new on the walls.

Haven’t posted in a while, but things are going great at the Owen Sound Artists' Co-op 😁

Just restocked greeting cards and I’ll be adding a few new acrylic prints over the next couple of weeks.

If you’re in the area, stop in and check out some of the great work being created locally.

The only time you’ll catch me up at 5am is after an astro night 🤣

Here’s to hoping for one of those again soon…
It’s been four months of absolute crap 😭

The word is in... I am officially a member of the Owen Sound Artists' Co-op 😁

This time last year I was just starting to put my site together. My plan was to eventually apply to be a guest artist at the co-op, but when they announced their Square Foot Show last summer, I submitted four prints. A couple of weeks later I got a call asking if I’d be interested in being a temporary member…

A big thank you to those who have purchased prints and cards since then, your support has helped solidify my spot in this amazing community of 45 local artists!

Angel Nebula (NGC 2170)

I started this and a few other projects back in October ’24, but only managed to gather enough data to finish my Orion mosaic (currently on display at the Artists Co-op) before the clear nights came to a halt ... the clouds continue. 😭

I’ll definitely need more luminance data to bring out the faint dust surrounding the nebula, and probably a decent amount of hydrogen to improve the reds. But, this is a solid start, and not too shabby for the old ASI1600 and 6″ Ritchey–Chrétien.

🔭My Orion photo is now up in the front window at the Owen Sound Artists' Co-op! I think it fits right in with the theme… stars! ✨

I’ll be at the co-op tonight from 5–9pm for Moonlight Madness if you want to stop by. Perfect time to get some holiday shopping done!
