Affiliate disclosure

Some of the links on this site are affiliate links. If you click one and buy something, the retailer may pay us a commission. You pay exactly the same price either way.

That is the entire commercial relationship. Nobody pays us for a review, for a placement, or for a kind word, and no merchant sees an article before it goes live.

Two, at the time of writing:

• Agena Astro — the default retailer link across mounts, optics, cameras, filters and adapters.
• Unistellar — smart telescopes and electronically assisted astronomy.

If we add another programme, it gets added to this list on the same day. A link that is not to one of the retailers named here is not making us money.

Most outbound links on this site are citations, not shopping links, and they earn nothing. Manufacturer manuals and spec sheets, technical write-ups, and retailers we link purely because they publish a specification worth quoting all fall into this group.

Several brands we recommend often have no affiliate programme at all. When we point you at them, there is no commission involved anywhere in the chain.

Several manufacturers in this hobby set a minimum advertised price, and street prices move constantly. A figure we printed once would be wrong within weeks, and a wrong price is worse than no price.

So we quote tiers and ranges, and send you to the retailer for the number that is true today. If you have ever wondered whether a missing price means we are hiding an affiliate markup — we are not, and this is why.

It does not, and the structure of the site is the argument for that. Specifications are checked against the manufacturer's own documentation rather than copied from another blog. Where the hobby genuinely disagrees, you get both positions and the reasoning instead of a verdict.

The most useful sentence we write is often the one that talks you out of a purchase. "You don't need this yet" is an answer we give frequently, and it earns us nothing.

Clicking an affiliate link may set a cookie that tells the retailer we referred you. That is how the commission is attributed. We do not receive your name, your payment details, or anything else about your order.

See our privacy policy for how the site itself handles data.

If a specification here is wrong, or a link behaves in a way this page does not describe, tell us and we will fix it and say what changed. Corrections go through the contact page.
