Celestron C9.25 Optical Tube Assembly (CGE Dovetail)

The legendary Celestron C9.25 occupies a unique place in the Schmidt-Cassegrain family — offering a perfect balance of aperture, performance, and portability. With its 9.25" (235 mm) aperture and 2350 mm focal length, this compact yet powerful optical tube delivers exceptional views of the Moon, planets, galaxies, and nebulae — all in a package that’s easy to transport and set up.

Despite weighing just 20 lb and measuring only 22" long, the C9.25 punches far above its size. Its f/10 optical system delivers high contrast and excellent clarity, while Celestron’s patented StarBright® XLT coatings maximise light transmission, giving brighter, sharper images and shorter exposure times for astroimagers.

Compatible with a wide range of mounts via its CGE-style dovetail bar, the C9.25 is widely regarded as the “Goldilocks” optical tube: not too big, not too small — just right for serious visual observers and astrophotographers alike.

Order Fulfilment

Some items, as clearly stated on the product page, may be fulfilled directly by our partners or manufacturers. In these cases, your order will be shipped to you straight from the brand’s warehouse. This helps us provide a wider range of specialist equipment and may result in slightly different delivery times.

Returns Policy

If something isn’t right, we’ll always try to help.

  • Unused items in “as new” condition can usually be returned within the statutory cooling-off period
  • Please contact us before sending anything back so we can advise on the safest way
  • For unwanted items, return shipping is your responsibility, and original shipping may be deducted where applicable
  • If a product is faulty or damaged, we’ll arrange repair, replacement or refund in line with your consumer rights — and we’ll cover reasonable return costs

Telescope shipping is expensive, and specialist — avoidable returns really do impact our business, so we always encourage customers to ask questions before buying. We’re here to help you get it right first time.

Your statutory rights are not affected.

Questions about this product?
Don't be a stranger.

Does it come with a warranty?

All our products are UK stock so come with manufacturers warranty

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.
