![]() ![]() Not compatible with #93648 Off-Axis Guider, not compatible with #93519 2" Mirror Diagonal (discontinued)Ĭurrently not compatible due to mechanical interferences Use them on your dew shield or anywhere else you like!Ĭheck out the 6” Dew Heater ring and the Smart DewHeater and Power Controllers to optimize your setup for the ideal dew-free night of observing and imaging. When purchasing this item, you will receive 2x adhesive Celestron logo labels. 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. 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. Simplify and streamline your setup with the Aluminum Dew Shield’s integrated cable management slot at the base. If you’re an astroimager who enjoys using your Schmidt-Cassegrain in the Fastar/Hyperstar configuration, you’re probably used to running cables out the front of the dew shield. The cover cap also offers you the ability to quickly and easily acquire dark frames for imaging. When your telescope is not in use, place the cover cap on your dew shield to protect your Schmidt corrector from stray dust particles. We’ve also constructed the cover cap from durable yet lightweight aluminum. Attach the dew shield to your telescope tube with the two adjustable clips to ensure a snug fit. Inside, a velvet-lined interior absorbs any additional stray light and excess moisture, creating optimal contrast when viewing and imaging. The exterior of the dew shield is a rigid, aluminum cylinder that will not fold, flex, or deform. The Aluminum Dew Shield provides a perfect, custom fit for 6” Celestron telescope tubes. Use the Aluminum Dew Shield on your 6” Schmidt Cassegrain telescope tube confidently, knowing it was created for your exact instrument. The Aluminum Dew Shield also increases image contrast by blocking stray light from entering the telescope for better viewing and astroimaging. The dew shield reduces radiative cooling of the Schmidt corrector lens to the night sky, keeping the lens below the dew point longer and preventing dew from forming on the lens. It’s an essential accessory that protects the tube in the field. Unique data from the Glory mission, along with NASA's fleet of Earth-observing satellites will help researchers investigate the intricacies of Earth's changing climate.Th is Aluminum Dew Shield with Cover Cap fits all 6” Celestron Schmidt-Cassegrain telescope tubes. The APS will provide a global dataset of aerosol distribution with unprecedented accuracy and specificity. The Aerosol Polarimitry Sensor, or APS, is among a suite of instruments on-board NASA's upcoming Glory mission. Narrator: New tools will soon help scientists study aerosols. Mischenko: We need to study the distribution of particles globally and the only way to do that is from satellites. Researchers are still working to understand the role of these curious particles. The suppression of clouds leads to further warming of the atmosphere, by solar radiation. When aerosols heat the atmosphere, they create an environment where clouds can't thrive. And others absorb radiation which warms the air. ![]() Some aerosol particles primarily reflect solar radiation and cool the atmosphere. Aerosol-rich clouds become bigger, brighter, and longer lasting.Īerosols impact clouds in other ways. Narrator: Clouds play an important role in regulating Earth's climate. Mischenko: The more aerosol particles we have in the atmosphere, the more cloud droplets we can have. Narrator: The introduction of too many aerosols wil modify a cloud's natural properties. Michael Mischenko, Glory Project Scientist, GISS: An aerosol particle can serve as a cloud condensation nucleus. Without aerosols, clouds could not exist. In just a short expanse of time, particles can change their size and composition and even travel across vast oceans.Īerosols are difficult to study and one important new area of research involves how these particles impact clouds. But they can also originate from human activity.Īerosols are short-lived but have an active lifetime. Sometimes aerosols occur naturally from things like volcanoes. Just like people, every particle is unique. Narrator: Aerosols are suspended throughout Earth's atmosphere and the tiny varied particles play a mysterious role in human-induced climate change. ![]()
