What happens if I don't like it?
We always want you to be happy with your purchase — so if you’re unsure, please ask us first. We’re always happy to give honest advice before you buy.
If the product arrives and you simply decide it isn’t for you, you can usually return it within the cooling-off period — as long as it’s unused, in perfect condition, and returned with all original packaging and accessories.
Because telescopes and optical equipment are large, delicate and expensive to ship, you’ll need to cover the cost of sending it back, and if we originally subsidised delivery, we may deduct our outbound shipping costs from your refund.
We’re a small specialist business, and unnecessary returns genuinely hurt us — so if you’re unsure at all, please talk to us first. We’d rather help you choose the right item than process a return.
How fast is shipping?
We aim to ship in-stock items as quickly as possible.
Most in-stock orders dispatch within 1–2 working days
Delivery usually takes 1–3 working days after dispatch (UK mainland)
Heavier / oversized items and special orders may take a little longer
You’ll receive tracking details as soon as your order is on its way.
Astronomy equipment often requires specialist packing and trusted couriers — we do this to keep your gear safe, not to slow things down. If you need something urgently, just ask and we’ll do our best.
