Dew & Dark
An evidence-based astrophotography site for the imager configuring their first serious rig — where every figure is traced to a named source, and the arguments that aren't settled are presented as arguments.
Most gear advice in this hobby is somebody's preference delivered in a confident tone. That's not useless — experience is worth something — but it's hard to check, and it tends to collapse into brand loyalty. Dew & Dark is built the other way round: start from what manufacturers actually publish, name the source next to the number, and where the hobby genuinely disagrees, show the disagreement instead of picking a winner quietly.
The site covers the decisions that come after "I want to photograph the sky" — payload margin, sampling, back focus, tracking. It's aimed at the point where you already know roughly what you want and need to work out whether the parts fit together before you spend money on finding out they don't.
How we work
Every load-bearing number traces to the manufacturer's own documentation or a measurement we can point at, with the source named next to the figure rather than in a bibliography you have to scroll to.
Some questions here don't have a settled answer — how far to derate a mount's rated payload is the clearest case. Those get both positions and the reasoning behind each, not a manufactured consensus.
If a figure is wrong we say so and fix it in the open. Telling us which guide and which line is the fastest kind of message to act on.
The most useful sentence we write is often the one that talks you out of a purchase. That is the point of the site, not a lapse in it.
How this is paid for
Dew & Dark is reader-funded. Some links are affiliate links — if you buy through one we may earn a commission, at no extra cost to you. It does not change what we recommend, and "you don't need this yet" is an answer we give often.
On prices: several manufacturers in this hobby — Celestron, Sky-Watcher, ZWO and iOptron among them — set minimum advertised prices, and street prices move constantly. So we quote tiers and ranges rather than exact figures, and link you to the retailer for the number that's true today. It's a dealer-terms constraint, not evasiveness.
What this site won't do
We don't answer "what telescope should I buy first?" It's a genuinely different question, it's well served elsewhere, and answering it badly is how most astro sites start.
Visual observing, eyepiece selection and planetary lucky imaging are barely touched here. And we don't publish specific prices for the MAP-enforced brands above.
