Large-format protection for Newtonians, RCs, and long refractors on EQ/GEM mounts.
The Standard Plus Series offers enhanced weather-resistant protection for telescopes mounted on equatorial mounts (EQ/GEM). The Size L version is built for longer tubes and setups measuring up to 50 inches (≈127 cm) in total length, including accessories.
Constructed with UV-resistant hexagon ripstop fabric and sealed interior seams, this cover protects your telescope from dust, dew, moderate rain, and sun exposure. Ideal for both indoor storage and temporary outdoor use.
Size L is a perfect fit for:
10” f/5 Newtonians
12” f/4 Newtonians
GSO RC 12” (carbon tube)
GSO RC 14” (steel tube)
ED/APO refractors up to 150 mm with long optical tubes
📏 To ensure correct fit, measure the total length of your telescope with mounted accessories (diagonal, camera, filter wheel, etc.). If your setup is 50” (127 cm) or shorter, this is the right size.
🛡️ Perfect for:
Home and observatory storage
Temporary field use at star parties or backyard setups
Protection from drizzle, dew, and moderate rain
Outdoor setups in sunlight — UV-stable up to 800 hours
⚠️ Not for long-term outdoor exposure to heavy rain. For extreme conditions, see our upcoming Titan Series.

🧭 A demo image explaining how to properly measure your telescope setup
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 L cover is designed for telescopes with a total setup length (tube + accessories) up to 50 inches (≈127 cm) — but the cover itself measures approximately 61 inches (≈ 155 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.
To determine if this cover will fit your telescope, measure the total length of your optical tube including any 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, as most accessories point downward in the parked position and don’t add to the total length of the setup.
Please keep in mind that the overall size of your telescope depends not just on the optical tube, but also the mount type, configuration, and accessories.
There are countless combinations of telescope + mount + accessories, and it’s simply 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, whether it’s a compact refractor or a large observatory-class setup.

Let us protect your scope — exactly the way it deserves.
