Celestron Large SCT & EdgeHD Adapter V2

Optimised Off-Axis Guiding for Full-Frame Imaging

Unlock the full imaging potential of your larger aperture Celestron telescope with the Large SCT & EdgeHD Adapter V2. Designed to pair seamlessly with the Celestron Off-Axis Guider, this precision-machined adapter expands your telescope’s usable image circle—ideal for astrophotographers using full-frame DSLRs or CCD cameras.

Key Benefits

  • Wider Illumination Area
    Provides a larger field of illumination for 9.25”, 11”, and 14” Schmidt-Cassegrain or EdgeHD optical tubes—perfect for full-frame sensors like the Canon 5D or 6D.

  • Improved Back-Focus
    The V2 version features an extended optical length of 38mm, delivering the correct back-focus for most DSLR setups without needing extra spacers or adapters when used with Celestron’s Off-Axis Guider.

Construction & Design

  • Durable CNC Machining
    Crafted from precision-machined, black anodised aluminium for lasting performance and a snug, secure fit.

  • Glare-Resistant Interior
    The internal surface is sandblasted to suppress reflections and improve contrast in your images.

  • Knurled Grip
    The external surface features a knurled texture, making it easy to install or remove—even in cold or gloved conditions.

Ideal Use Case

This adapter is a must-have for astrophotographers using large-format sensors and looking to maximise field illumination without vignetting. When paired with the Celestron Off-Axis Guider, it ensures optimal star tracking, better contrast, and a higher quality imaging workflow on large SCT and EdgeHD telescopes.

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.
