Telescope Cover (Size XS) on Equatorial (EQ/GEM) – Titan

This Titan Series cover is specially designed for telescopes mounted on equatorial (EQ/GEM) mounts with compact optical tubes.

Size XS is ideal for smaller setups, such as ED and APO refractors (50–80 mm / 2”–3”), as well as compact SCTs and Maksutov-Cassegrains.

📏 To ensure proper fit, the total length of your optical tube and attached equipment (diagonal, camera, filter wheel, etc.) should not exceed 20 inches (≈ 51 cm).

Always measure your setup with accessories installed before selecting a size.


Built for Long-Term Outdoor Protection

Titan Covers are engineered for long-term outdoor storage of telescopes and mounts. They provide reliable protection against rain, snow, UV exposure, and temperature fluctuations — keeping your equipment safe and ready to use in any season.

Each Titan cover is made from two carefully selected fabrics — an outer waterproof shell and an inner thermal barrier fabric.

  • The outer fabric is a PVC-coated nylon that delivers 100% waterproof performance (tested above 7000 mmH₂O, AATCC-127). It’s durable, UV-resistant, color-stable, easy to clean, and keeps its shape outdoors.
  • The inner fabric has a multi-layer structure: a cotton base for thermal stability and a silvered surface that acts as a heat barrier, helping reduce rapid temperature swings (e.g., early morning warm-ups). Its waterproof face adds extra moisture protection.

Thoughtful Design & Reliable Sealing

All seams are treated with a specialized sealing compound, and the waxed, water-resistant threads prevent moisture absorption — resulting in a fully sealed construction for harsh weather.

For ease of use, the cover includes:

  • 🖐 Two integrated handles for quick removal and placement.
  • 🪝 Elastic drawcord with a toggle for a snug fit around the base.
  • 🔒 Corded hem with locking fasteners for secure anchoring in wind.

Condensation & Optional Add-Ons

Under certain conditions, condensation may form inside any outdoor cover — including Titan. To help reduce humidity and protect sensitive optics, we offer optional add-ons:

  1. Removable desiccant pocket with reusable silica gel — maintains lower humidity inside the cover; the indicator shows when to dry it.
  2. Ventilation fan — circulates air to prevent moisture buildup. Power via 12 V or the included USB adapter (low/high speed; can run from a power bank).

⚠️ The fan option must be selected at the time of purchase. It is integrated during production and cannot be added later.


Additional humidity-control options will be available soon.

📏 Dimensions of this cover

Understanding the Cover Dimensions

The illustration shows the actual dimensions of this telescope cover.

These dimensions are slightly larger than the maximum recommended telescope length for this size to allow for an easy and proper fit.

For example, the Size XS cover is designed for telescopes with a total setup length up to 20 inches (≈51 cm) — but the cover itself measures approximately 24 inches (≈61 cm) in length.

This built-in allowance ensures:

  • ✅ Easy placement and removal of the cover
  • ✅ A proper fit without straining the fabric or seams
  • ✅ Better airflow and protection around attached accessories

All sizes are designed with this margin to accommodate real-world telescope configurations.


✅ How to Measure Your Telescope

To determine if this cover will fit your telescope, measure the total length of your optical tube including equipment attached to the focuser — such as a diagonal, camera, filter wheel, or other accessories.

📌 For Newtonian telescopes, you typically only need to measure the tube length, since most accessories point downward in the parked position and don’t add to the total length.

Please keep in mind that the overall size of your telescope depends not only on the optical tube, but also the mount, configuration, and attached accessories.


⚠️ Many Scopes, Many Combinations

There are countless combinations of telescope + mount + accessories, and it's not possible to offer a pre-made cover for every setup.

That’s why we offer a custom telescope cover service — tailored specifically for your equipment.

We create covers for any telescope type or size, from compact refractors to large observatory-class instruments.
