A trifle pricey but adequate, and essential for my purposes.

I purchased the Celestron 11" Aluminum Dew Shield with Cover Cap as an indispensable adjunct to the Celestron RASA-11 telescope. Since the camera can only be installed in front of the corrector plate, I needed a sturdy and rigid dew shield with a cap in order to take dark frames, which are essential in calibrating astronomical images. Also the dew shield enables me to capture flat frames using a light panel which I mount atop the dew shield when the scope is flipped vertical; otherwise I would have to shoot twilight or t-shirt flats, a much less convenient and efficient method. This dew shield works quite well, with no light leaks. It replaces a flexible model which proved to be completely inadequate. The only drawback to the aluminum dew shield is that it is not solidly anchored to the scope, is a trifle unstable and shifts a little when the scope is slewed. But it stays in place and doesn't fall off. For me, it is an essential and welcome adjunct to the scope.

Are you an astronomy enthusiast or a professional astroimager seeking a reliable solution to protect your telescope tube in the field The Celestron 8" Aluminum Dew Shield with Cover Cap is a high-quality, durable accessory designed specifically for your needs. This effective dew shield significantly reduces radiative cooling of the Schmidt corrector lens, keeping it below the dew point for longer periods. This prevents dew formation on the lens, ensuring clear, unobstructed viewing and astroimaging.

The Celestron Aluminum Dew Shield is not just a protective accessory; it also enhances your viewing experience by increasing image contrast. It achieves this by blocking stray light from entering the telescope, providing you with better, more detailed images. This makes it an ideal accessory for use with your 8" EdgeHD, RASA, or Schmidt Cassegrain (manufactured after 2006) telescope tube.

Constructed with precision, the Aluminum Dew Shield offers a perfect, custom fit for 8" Celestron telescope tubes. The exterior is a rigid, stylish black aluminum cylinder that maintains its shape without folding, flexing, or deforming. Inside, a velvet-lined interior absorbs any additional stray light and excess moisture, creating optimal contrast for viewing and imaging.

The dew shield attaches securely to your telescope tube with two adjustable clips, ensuring a snug fit. The cover cap, made from lightweight yet sturdy aluminum, protects your Schmidt corrector from stray dust particles when your telescope is not in use. It also facilitates the quick and easy acquisition of dark frames for imaging.

For those who use their Schmidt-Cassegrain or EdgeHD in the Fastar/Hyperstar configuration or the RASA, the Aluminum Dew Shield features an integrated cable management slot at the base. This handy feature allows you to organize essential cables, like those for our Dew Heater rings, without letting light pollution leak in. The shield also includes cutouts to accommodate dovetail rails on the top and bottom of the telescope tube, ensuring a good fit regardless of the configuration.

In summary, the Celestron 8" Aluminum Dew Shield with Cover Cap is a protective, effective, and stylish accessory that enhances your astroimaging experience while ensuring the longevity of your telescope tube.
