Telescope Cover (Size XL) on Equatorial (EQ/GEM) – Titan
This Titan Series cover delivers maximum protection for large, observatory-class telescopes mounted on equatorial (EQ/GEM) mounts.
Size XL is our largest format, designed for extra-long optical tubes with attached accessories. It fits setups with a total length of up to 60 inches (≈ 152 cm) — ideal for 16″ Ritchey-Chrétien, 12″ f/5 Newtonians, long-focus refractors 150–160 mm, and other large telescopes of similar size.
📏 Always measure the full length of your telescope, including all attached components (diagonal, filter wheel, camera, etc.), before ordering.
Built for Long-Term Outdoor Protection
Titan Covers are engineered for long-term outdoor storage of telescopes and mounts, providing reliable protection against rain, snow, UV exposure, dust, and sudden temperature fluctuations.
Each Titan cover is made from two high-quality fabrics — an outer waterproof fabric and an inner thermal barrier fabric. Together they form a complete protection system for year-round use, whether in a home observatory or under open skies.
The outer fabric is a PVC-coated nylon that ensures 100% waterproof performance (tested above 7000 mmH₂O, AATCC-127). It’s UV-resistant, durable, color-stable, and easy to clean.
The inner fabric has a multi-layer structure with a cotton base for insulation and a silvered surface that serves as a heat barrier, helping to prevent dew and smooth out temperature changes. Its waterproof face adds an additional layer of moisture defense.
Thoughtful Design & Reliable Sealing
All Titan covers feature sealed seams and waxed, water-repellent threads, ensuring complete protection from moisture penetration.
For user convenience, each cover includes:
🖐 Two reinforced handles for easy placement and removal.
🪝 Elastic drawcord with toggle for a snug, secure fit around the base.
🔒 Corded hem with locking fasteners to prevent lifting in windy conditions.
Condensation & Optional Add-Ons
In certain environments, condensation may form inside any outdoor cover. To help reduce humidity and protect sensitive optics, Titan covers can be ordered with optional accessories:
Removable desiccant pocket with reusable silica gel — maintains low humidity inside the cover. The silica gel includes a color indicator that shows when it’s time to dry and reuse.
Ventilation fan — improves air circulation inside the cover and helps prevent moisture buildup. The fan can be powered by a 12 V source or via the included USB adapter, allowing operation from portable power banks in the field.
⚠️ The fan option must be selected at the time of purchase; installation requires factory sealing and cannot be added later.
