Celestron Aluminum Dew Shield with Cover Cap – 11”

Designed for 11” Celestron Schmidt-Cassegrain, EdgeHD, and RASA OTAs (post-2006), the Celestron Aluminum Dew Shield is a robust, purpose-built solution for preventing dew and improving image contrast during observation or astrophotography sessions.

Key Benefits

  • Prevents Dew Formation: Reduces radiative cooling of the corrector plate, keeping the optics clear longer under humid or cold conditions.

  • Boosts Image Contrast: Velvet-lined interior blocks stray light and absorbs excess moisture, helping you achieve sharper, higher-contrast views.

  • Custom Fit for 11” OTAs: Compatible with Fastar/Hyperstar and RASA configurations, with precision cut-outs for top/bottom dovetail rails.

Built for Durability & Performance

  • Rigid Aluminium Construction: Won’t flex, fold, or deform in the field.

  • Secure Fit: Attaches via two adjustable clips for stability and ease of use.

  • Integrated Cable Management: Dedicated slot lets you route cables without disrupting the light seal—ideal for dew heater rings or Hyperstar cabling.

  • Aluminium Cover Cap: Protects your optics from dust and enables easy dark frame acquisition during imaging sessions.

What’s Included

  • 11” Aluminium Dew Shield

  • Matching Aluminium Cover Cap

  • Integrated Cable Slot & Dovetail Cut-outs

  • 2x Adhesive Celestron Logo Decals

Ideal Pairings

  • Celestron 11” Dew Heater Ring – Direct, efficient optical heating

  • Smart DewHeater Controller – Real-time heat management based on humidity and temperature

  • PowerTank Series – For reliable off-grid power during long sessions

Built specifically for your Celestron 11” OTA, this premium dew shield enhances performance, protects optics, and simplifies cable routing—essential for serious observers and astroimagers.

Order Fulfilment

This helps us provide a wider range of specialist equipment and may result in slightly different delivery times.

  • Please contact us before sending anything back so we can advise on the safest way

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.
