R-Sky Standard Plus telescope covers

The Standard Plus Series from R-Sky includes protective covers for a wide range of Dobsonian and equatorially mounted telescopes. These covers are available in two color options, silver and black, and are constructed from hexagon-pattern ripstop polyester. This material is coated with polyurethane and features sealed interior seams. The sealed seams are designed to improve the cover’s resistance to dew and moderate rainfall during short-term outdoor use. The fabric includes ultraviolet resistance rated for up to 800 hours of direct sunlight. Each cover includes a drawstring base with cord locks to secure it to the telescope and reduce exposure to dust, insects, and moisture.

R-Sky Standard Plus telescope covers for Dobsonian and EQ-Mounted Scopes

All covers in the Standard Plus Series have a soft interior surface that prevents direct abrasion against optical tubes and painted components. A top handle is included for ease of installation and removal. These telescope covers are designed for both manual and Go-To Dobsonians, as well as tube-and-mount combinations set up on EQ or GEM mounts. The product line is made in the United States.

The 6-inch Dobsonian cover fits standard 6-inch Dobsonian telescopes. This includes models from Sky-Watcher, Meade, Celestron, Explore Scientific, and other manufacturers with similar OTA and base dimensions. The 6-inch model protects against surface dust, moisture from dew, and short-term exposure to light precipitation. It includes all the structural and fabric features of the full series. The price for this model is $75.00.

The 8-inch Dobsonian cover is built to fit typical 8-inch Dobsonian scopes with similar construction. It uses the same material and construction features, including sealed seams and drawstring closure. The 8-inch model is also priced at $75.00 and is compatible with common 8-inch telescope models across major manufacturers.

The 10-inch Dobsonian cover expands on the series with a slightly larger form factor to accommodate the increased tube length and base width of 10-inch Dobsonians. The cover retains the polyurethane-coated, UV-resistant, sealed-seam construction. It includes the soft inner lining and adjustable cord locks. This model is priced at $78.00.

The 12-inch Dobsonian cover offers a longer and wider fit for 12-inch Dobsonian telescopes. It uses the same ripstop fabric and includes sealed seams, drawstring base, and handle. It is intended for field or indoor use where temporary exposure to dew and mild rain may occur. The price is $81.00.

The 14-inch Dobsonian cover is compatible with 14-inch Dobsonians, including Go-To versions that may have additional height from altitude motors. The sealed seams and UV resistance are standard across the series. The price is $86.00. This model retains the reinforced handle and internal lining for surface protection.

The 16-inch Dobsonian cover is the largest in the Dobsonian segment of the Standard Plus line. It fits standard 16-inch Dobsonian telescopes, including those with larger rocker boxes or integrated electronics. The same sealed seam, drawstring base, UV resistance, and internal soft lining are included. The price is $95.00.

Standard Plus telescope covers for EQ and GEM Mounts (Sizes XS to XL)

For telescope users operating on EQ or GEM mounts, the Standard Plus Series includes five size options. These range from Size XS to Size XL and are based on optical tube length rather than aperture diameter. All models retain the same material structure, internal seam sealing, UV resistance, and drawstring closure found in the Dobsonian models.

The Size XS cover fits telescope tubes up to 20 inches (51 cm) in length. This includes small refractors and compact reflector designs. The cover is compatible with EQ and GEM mount configurations and includes the top handle for removal. The price for the XS size is $75.00.

The Size S cover supports optical tubes up to 30 inches (76 cm) long. This model is designed for longer refractors or small to mid-sized Newtonian reflectors. It retains the same hexagon ripstop polyester with polyurethane coating, sealed seams, and PFAS-free surface. The price is $75.00.

The Size M cover accommodates telescopes up to 40 inches (102 cm) long. This includes many larger refractor OTAs and longer Newtonians used on EQ mounts. The M-size cover is priced at $80.00 and includes the full feature set of the Standard Plus Series.

The Size L model fits optical tubes up to 50 inches (127 cm). This is suitable for large refractors and certain long-focus Newtonians or hybrid designs. It uses the same internal soft lining and UV-resistant materials and includes the reinforced handle and drawstring lock system. The price is $89.00.

The Size XL cover supports optical tubes up to 60 inches (152 cm) in length. This size is appropriate for the largest refractors and Newtonian setups used on German equatorial mounts. It includes the full set of features: water resistance via sealed seams, drawstring closure, UV treatment for 800 hours of exposure, and soft inner lining. The price is $95.00.

Each size in the Standard Plus Series is designed to be lightweight and compact when folded. These covers are intended for storage and transport where the goal is to minimize exposure to environmental contaminants. While they can withstand short-term exposure to moisture and sun, they are not rated for continuous or heavy rainfall. For telescopes that remain outside in all conditions, R-Sky plans to release a separate Titan Series designed for long-term exposure.

The construction of each cover includes sealed interior seams to improve water resistance beyond what standard stitched seams can offer. The ripstop polyester is structured in a hexagon weave pattern and coated with polyurethane to reduce water absorption. The UV resistance is built into the outer layer to prevent material breakdown from solar radiation. The inner lining is non-abrasive to reduce potential scratching or wear on painted or anodized surfaces.

Each cover is equipped with a drawstring at the base that uses cord locks to secure the fit. This system helps ensure the cover stays in place when used outdoors. The handle at the top of each cover is designed to assist with fast application and removal. This feature is positioned for balance and reach when accessing the telescope.

All models are made without PFAS chemicals. The PU coating used in the cover material is listed as compliant with PFAS-free standards. The Standard Plus Series is manufactured in the United States. Sizes are determined by diameter (for Dobsonian models) or tube length (for EQ/GEM models). For users with telescopes that do not fit within the listed dimensions, custom sizing is available by request. A cover configurator tool is in development to assist with custom fit selection.

The Standard Plus Series is not rated for thermal insulation or sub-zero protection. It is also not intended for use in high wind or storm conditions. When used indoors, the covers help reduce dust accumulation and exposure to airborne particles. When used outdoors, the covers help prevent dew formation on optical and mechanical surfaces during inactive periods. They are not designed to function as rain covers in heavy or prolonged precipitation.

Each model folds compactly for transport. No storage bag is included, but the material allows for rolling or folding into minimal volume. The covers are intended for repeated folding and unfolding without loss of integrity. The hexagon-pattern ripstop prevents small tears from expanding during use.

The Dobsonian cover dimensions vary by aperture. The 6-inch cover supports the standard base and tube height for most commercial 6-inch Dobs. The 8-inch model extends in height and base width to fit typical 8-inch scopes. The 10-inch cover expands further for increased rocker box width and tube height. The 12-inch, 14-inch, and 16-inch models continue this pattern of expansion based on common telescope specifications. The covers are not specific to a single manufacturer and are meant to fit common form factors.

The EQ/GEM series is measured by tube length, not focal length or aperture. For example, a telescope with a 900 mm focal length and 100 mm aperture may fall into the S or M size range depending on OTA construction. Users are advised to measure the total OTA length, including attached dew shields or accessories, when selecting a size. Product pages on the R-Sky website include sizing charts and fitting notes for each model.

Maintenance, and usage guidelines for Standard Plus covers

Covers in the series do not include vents, access flaps, or zippers. They are single-piece units designed to be placed over the telescope from the top down. The drawstring base is the only adjustable element. The lack of vents means that the interior air is not actively exchanged, which may limit use in high-humidity conditions if the cover remains in place for extended periods. The primary use case is short-term protection between observing sessions, either during the night or between nights in dry conditions.

The covers can be cleaned using mild detergent and water. Machine washing is not recommended. The interior lining is not removable. Users should inspect the cover regularly for seam separation or fabric wear, especially at fold points and drawstring seams. If stored for long periods, the cover should be kept in a dry, low-humidity environment to prevent mildew or fabric degradation.

In summary, the Standard Plus Series from R-Sky provides telescope-specific coverage for Dobsonian and EQ/GEM-mounted scopes using sealed fabric, UV-resistant coatings, and secure closures. The product list includes 6-inch to 16-inch Dobsonian models and XS to XL EQ/GEM models, with prices ranging from $75.00 to $95.00 depending on size. All models are designed for short-term exposure to dew and moderate rainfall, with soft interiors, secure drawstring bases, and reinforced top handles for handling. Custom sizes are available by request. The product line is manufactured in the USA and made from PFAS-free materials.
