Celestron Dew Heater Ring for 5” SCT

Keep your optics clear and your observing uninterrupted with the Celestron Dew Heater Ring, tailored for 5” Celestron Schmidt-Cassegrain telescopes. This essential upgrade replaces the stock retaining ring, offering an efficient, permanent dew prevention solution ideal for year-round astronomy.

Advanced Dew Control with Direct Heating

Unlike external heat bands, this ring delivers heat directly to the corrector glass, providing faster and more efficient dew prevention. The precision-engineered aluminium frame supports the Schmidt corrector and houses the internal heating circuitry.

Connect the ring to a 12V DC power supply for consistent heat in even the most humid conditions. Storage clips keep the power and thermistor jacks secure, while the included cable clip keeps your setup organised and strain-free.

Smart Compatibility

Equipped with a built-in thermistor, this ring pairs perfectly with Celestron Smart DewHeater Controllers (sold separately). The controller automatically adjusts heat output based on environmental and optical temperatures, helping conserve power and extend battery life.

Order Fulfilment

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

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.
