Telescope Cover for 12″ Dobsonian – Titan Series
This Titan Series cover is designed for 12-inch Dobsonian telescopes, offering full protection for both the optical tube and the base. Built for extended outdoor storage, it shields your telescope from rain, snow, UV exposure, and dust, while helping to minimize rapid temperature changes that can cause condensation.
The shape is optimized for Dobsonian designs, ensuring a secure fit for both classic manual telescopes and Go-To models with electronics.
Engineered for Outdoor Durability
Titan covers are built for reliable, long-term use in outdoor environments. Each cover combines two high-quality fabrics — an outer waterproof fabric and an inner thermal barrier fabric — working together to protect your equipment in changing weather conditions.
-
The outer fabric is made from PVC-coated nylon, delivering 100% waterproof performance (tested above 7000 mmH₂O, AATCC-127). It provides excellent resistance to UV, abrasion, and long-term exposure.
-
The inner fabric features a multi-layer construction with a durable cotton base that enhances insulation and a silvered surface that acts as a heat barrier, helping to reduce temperature swings and limit dew formation. Its waterproof face adds an additional moisture shield.
Seams are fully sealed, and waxed, water-repellent threads prevent water ingress. Reinforced handles and an adjustable drawcord help keep the cover secure even in windy conditions.
Condensation & Optional Add-Ons
Depending on environmental conditions, condensation can form inside any outdoor cover, including Titan. To help manage internal humidity, optional accessories are available:
-
Removable desiccant pocket with reusable silica gel — reduces moisture levels inside the cover and includes an indicator for reactivation.
-
Ventilation fan — improves airflow and helps prevent moisture buildup. Powered via 12 V or the included USB adapter, making it suitable for use with portable power sources.
⚠️ The fan must be selected at the time of purchase and cannot be added later due to integrated installation.
