Hi, I'm Tim

Lifelong stargazer, imager, dark site traveller โ€” and the person who got tired of checking five different apps just to find out if it was clear out.

"I just wanted a simple, easy way to know if the sky was clear โ€” and what was up there worth looking at."
โ€” Tim, founder of What's Up Tonight

It started the way most astronomy stories do โ€” gathered around the television as a small child watching the moon landing with family. Something about that flickering black and white image of a human being standing on another world stayed with me. From that moment, the Moon and planets weren't just things in the sky. They were places.

That early fascination never really went away. As I got older it quietly grew into something more serious โ€” learning the constellations, tracking the planets, understanding why the sky changes with the seasons. Astronomy became less of a hobby and more of a lifelong companion.

EARLY YEARS
Started as a visual observer with modest gear โ€” a small telescope pointed at the Moon, Saturn's rings for the first time, Jupiter's moons lined up like tiny beads. Those first views never get old.
EARLY 2000s
Discovered star parties โ€” and got completely hooked. There's nothing quite like setting up under truly dark skies with a group of people who share the same passion. The camaraderie, the shared eyepiece, the collective "wow" when someone finds something special.
OVER TIME
Transitioned into astrophotography โ€” the long patient process of capturing what your eye can barely see. Started with modest equipment and gradually, fortunately, built up a variety of gear over the years.
TODAY
Primarily an imager โ€” but while the camera does its work, you'll find me scanning the sky with binoculars or a small telescope. Dark site trips are a regular part of life, alongside a home observatory for those nights when the weather cooperates closer to home.

I'm based in Ontario, Canada โ€” which means dealing with some interesting weather and genuinely appreciating every clear night we get. I travel regularly to darker sites when the forecast cooperates, but a home observatory means I can always take advantage of a surprise clear sky without much fuss.

With a background in culinary arts, sales, and a lifelong interest in computers and technology, I've always been drawn to building things that solve real problems. And astronomy had a very real problem that nobody had properly solved.

Every clear night starts the same way โ€” checking the weather, checking a forecast site, checking a moon phase app, checking another site for ISS passes, checking something else for what's visible tonight. It's five apps for a simple question: is it worth going out?

What's Up Tonight is my answer to that. One place. Any location. Everything you need to decide in seconds whether tonight is worth setting up โ€” or whether you should save your energy for a better night. Built by an astronomer, for astronomers, whether you're a complete beginner or a seasoned observer with a serious setup.

I hope it saves you time, protects your equipment from surprise dew and rain, and helps you never miss one of those rare exceptional nights again.

Clear skies. ๐Ÿ”ญ

I share images, observing reports and sky updates on Instagram. Come say hello โ€” the astronomy community is one of the friendliest corners of the internet.
