Telescope-Dew & Moisture Protection-Apertura 8″ SCT Dew Shield

Apertura 8″ Flexible Dew Shield with Single Notch for Celestron 8″ SCTs

If you’re looking for a dew prevention and stray light protection solution with a worry-free fit, look no further than the Apertura 8″ SCT Dew Shield! This flexible dew shield has been designed for Celestron 8″ SCTs with the single narrow Vixen style dovetail bar, ensuring 8SE, 8″ Evolution, 8″ EdgeHD, and C8 OTA owners have a snug-fitting premium shield. Made in the USA, the Apertura 8″ SCT Dew Shield is the choice for a quality built, comfortably padded, light-blocking, and easily installable dew shield.

While there is a lot to like about the Schmidt-Cassegrain telescopes from Celestron, their large corrector plate (inherent to the SCT design) does make them more prone to dew formation than other telescope designs. This is where a dew shield comes in, allowing SCT owners to gain the dew protection of other telescope designs while keeping all the optical performance they love – and in some cases even improving it! With its long cone built for insulating the corrector plate, the Apertura 8″ SCT Dew Shield can additionally benefit those in areas where stray light from street lights or houses is a concern, by blocking this off-axis light from entering the optics and degrading the view/ image.

Premium Quality, Performance, and Precision Fit!

With the plethora of components that can go into astronomy setups today, it is important that to have equipment that you can rely on not to slow you down. Apertura has created the 8″ SCT Dew Shield with this goal in mind, bringing you a shield tailor-made for Celestron SCTs that truly is just set-and-forget easy to use. Better still, this is made with high-quality material in the USA – ensuring you can rely on the Apertura 8″ SCT Dew shield for many years to come!

Flexible, Durable, ABS Construction
To create a dew shield that is sturdy enough to form a rigid cone around your optics, but malleable enough that it can be removed and adjusted over and over again, Apertura has made the 8″ SCT Dew Shield out of ABS. Well-known for its durability, ABS is used in many hard-use applications and is a perfect choice for a tough shield that you can use – and then roll up or press flat for storage – for years to come.

Dew Prevention and Light Rejection Power
Dew shields guard your optics from moisture by creating a “pocket” of warmer air in front of the corrector plate. By utilizing ABS in its construction, the 8″ SCT Dew Shield excels at trapping this warmer air and passively keeping your optics above the dewpoint for longer. These shields have an added benefit of blocking stray light from entering the optics and degrading your viewing or imaging experience, but Apertura has taken it a step further by lining the inside of the dew shield with a light absorbing material. Known as flocking, this prevents light from reflecting off the inside surface of the shield, keeping your views as crisp as possible.

A Secure, Finish-Safe, Fit
The Apertura 8″ Dew Shield has been designed to fit the most popular 8″ SCTs from Celestron, hugging the front of your OTA and contouring to single narrow Vixen-style dovetail models with a dedicated notch. With a full-length strip of Velcro on the dew shield’s edges, this is easy to install and will stay right where you put it! Simply line up the 8″ SCT Dew Shield’s notch around your dovetail bar, wrap around, and press the ends together to add a layer of dew and stray light protection to your SCT. To provide the best seal and protect the finish of the telescope, a 2″ section of soft padding foam runs across the entire contact area.
