94024 Aluminum Dew Shield with Cover Cap - 14" by Celestron

The Celestron Aluminum Dew Shield with Cover Cap is an essential accessory that protects your telescope tube in the field. The dew shield reduces radiative cooling of the Schmidt corrector lens to the night sky, thus keeping the lens below the dew point longer preventing dew formation on the lens. Additionally, the Aluminum Dew Shield increases image contrast by blocking stray light from entering the telescope for better viewing and astroimaging. Use the Aluminum Dew Shield on your 14" EdgeHD, 36cm RASA, or Schmidt Cassegrain (made after 2006) telescope tube confidently, knowing it was created for your exact instrument.

Construction

The Aluminum Dew Shield provides a perfect, custom fit for 14" Celestron telescope tubes. The exterior of the dew shield is a rigid, aluminum cylinder that will not fold, flex, or deform. Inside, a velvet-lined interior absorbs any additional stray light and excess moisture, creating optimal contrast when viewing and imaging. Attach the dew shield to your telescope tube with the two adjustable clips to ensure a snug fit.

We've also constructed the cover cap from durable yet lightweight aluminum. When your telescope is not in use, place the cover cap on your dew shield to protect your Schmidt corrector from stray dust particles. The cover cap also offers you the ability to quickly and easily acquire dark frames for imaging.

If you're an astroimager who enjoys using your Schmidt-Cassegrain or EdgeHD in the Fastar/Hyperstar configuration or the 36cm RASA, you're probably used to running cables out the front of the dew shield. Simplify and streamline your setup with the Aluminum Dew Shield's integrated cable management slot at the base. This slot gives you an easy way to corral essential cables (like the ones for our Dew Heater rings) without potentially allowing light pollution to leak in. Also, there are cutouts to accommodate dovetail rails on the top and bottom of the telescope tube, ensuring a good fit regardless of the configuration.

Enhance your setup

When purchasing this item, you will receive 2x adhesive Celestron logo labels, which can be applied to the dew shield, or anywhere else you like!

Check out the 14" Dew Heater ring and the Smart DewHeater and Power Controllers to optimize your setup for the ideal night out observing and imaging.

1295-0552 Chemcassette Tape, Sulfur Dioxide by Honeywell Analytics

Chemcassette® is the unique trademarked name for a calibration free toxic gas detection method that uses an optical scanning system to detect the presence of gas by a colour change on the specially chemically impregnated paper tape. Chemcassette® technology is highly specific and reacts extremely fast to the presence of parts per billion (ppb) levels of many hazardous gases. Over 200,000 points of gas detection are currently maintained by the Chemcassette® sensing technology at any given time around the World in some of the most critical safety applications possible.

Each Chemcassette® is manufactured to traceable ISO 9000 manufacturing standards by a world class team of highly trained chemists and each batch is calibrated with ultra pure gas that is traceable to nationally accepted standards. This means that the end user does not have to provide calibration facilities themselves thereby saving cost and reducing risks to their own staff.

Efficient high volume manufacturing techniques means that there is always available Chemcassette® in stock that can be shipped anywhere in the World so that our customers are never left without adequate safety cover. Application support with expert gas detection chemists is available by phone and e-mail and is supported with many years of technical application notes and help to diagnose common support issues.

Should there be any concern regarding the performance of an individual Chemcassette®, a free of charge evaluation will be performed to trouble shoot the observed scenario using the award winning quality management system "Customer Discrepancy Report" CDR. Every CDR completed by a customer is guaranteed a full response and the outcome is reported directly back to the end user to ensure a complete resolution process.

Each Chemcassette® is backed with a full warranty and we have over 20 years of experience regarding the quality control of our proven sensing technology.

Additional Features and Benefits:

• Visible proof of a gas release event
