Beginner's guide to setting up a proper sky watch — lessons learned from two years of freezing in Yorkshire

I've been meaning to write this up for ages, so here it is. Two years ago I started taking skywatching seriously after a sighting near Ilkley Moor - nothing dramatic, just a light that moved in a way I couldn't explain - and I've learned an enormous amount about what equipment actually works, what's a waste of money, and how to keep records that are genuinely useful rather than just a notebook full of "saw something bright, wasn't a plane, probably." This is aimed at complete beginners but I hope even the more experienced watchers might find something useful.

First thing: the cold will defeat you before the sky does. Yorkshire moors in October feel like standing inside a freezer that someone has also filled with damp. Your hands stop working, your torch battery dies, your enthusiasm evaporates. Get proper thermal underlayers, a decent flask, and waterproof everything. I cannot stress this enough. I ruined a perfectly good night-vision monocular because I didn't account for condensation. That was a £180 mistake I only needed to make once.

For kit, I currently run a Bresser night-vision monocular (picked mine up secondhand for about £90), a basic Sony camcorder with night-shot mode, and my mobile on a tripod running a sky-tracking app. I've tried various IR illuminators and honestly the budget ones from Amazon are fine for the distances we're talking about. The expensive gear helps but it's not the difference between seeing something and not seeing something - that's mostly about location, patience, and logging discipline.

On logging: keep a standardised record for every session even if nothing happens. Date, time, location coordinates, weather conditions, cloud cover percentage, temperature, any aircraft you positively identify (and how). The negative data is almost as useful as the positive data. After six months you'll start to notice patterns - certain conditions, certain locations, certain times of year that produce more unexplained observations. That's when it gets interesting.

Brilliant write-up, thank you for this. The logging discipline point is one I wish someone had hammered home to me earlier. I've got about eight months of notes from sessions on the North Yorkshire coast that are basically useless because I wasn't consistent - different formats, variable levels of detail, sometimes nothing at all for sessions where I convinced myself nothing noteworthy happened. In retrospect several of those "unremarkable" nights had conditions and observations that would have been genuinely interesting in comparison to the rest of the dataset.

Can you say more about the Ilkley Moor area specifically? I know there's a bit of history there - the Philip Spencer photograph from 1987 and so on - and I've been thinking about doing a dedicated watch weekend up there in the spring. What are the access and parking situations like? Assume I'll be coming up from Sheffield so it's not a massive journey but I'd like to be prepared.

That was a £180 mistake I only needed to make once.

Ha, I made the same mistake with a thermal imaging camera attachment that cost considerably more than that. In my case it wasn't condensation - I simply dropped it down a hillside on Bodmin Moor at 2am in the dark. It's probably still there. Some future archaeologist is going to be very confused.

Good guide overall. One thing I'd add for beginners: learn your aircraft. I mean really learn them. Know what a commercial flight at 35,000 feet looks like versus a low military exercise, know what helicopter navigation lights look like versus fixed-wing, know what the ISS passage looks like and when to expect it. Not because everything unusual is secretly an aircraft - but because confidently ruling out the conventional explanations is what makes an unexplained observation actually compelling. "I saw a light and I don't know what planes look like" is not a UAP report. "I'm a trained observer and this didn't match any aircraft behaviour I've seen in two years of watching" is a very different thing.

What sky-tracking app are you running on your mobile, if you don't mind? I've tried a few and they're all slightly annoying in different ways. Also, does anyone have experience with the new Bresser NV range versus the older ones? My monocular is about four years old now and I'm wondering if the newer models are meaningfully better or if it's marginal.

The tip about negative data is something I took to heart after reading this post and it's already changing how I keep records. Did a session last weekend outside Harrogate - four hours, perfectly clear, nothing unusual at all - and instead of writing "nothing happened" I properly logged fourteen identified aircraft, two satellites, Jupiter, and the conditions. Felt a bit pointless at the time but I can see how it builds into something over months. Good shout.

If anyone's looking at the Scottish end of things, I've found the areas around Loch Ness and further north toward Inverness genuinely productive - less light pollution than almost anywhere in England and the topography seems to... concentrate things, if that makes any sense. The downside is the midges from June to September will eat you alive and make sustained observation basically impossible without a full head net, which makes you look absolutely ridiculous but is entirely worth it.

Decent guide but I'd push back slightly on the "budget IR illuminators are fine" take. I upgraded from a cheap one to a decent Evolva unit and the difference at range is significant - the cheap ones get you maybe 30 metres of usable illumination, the better ones push that out considerably. If you're watching over open moorland the range matters. If you're in a garden or a field watching a small patch of sky, then yes, probably fine. Depends what you're trying to do.
