93571 1.25" Dielectric Mirror Diagonal, Twist-Lock by Celestron

Ensure maximum light transmission without loss of optical quality with the Celestron Dielectric Star Diagonal, 1.25" with Twist-Lock. Upgrade your existing star diagonal to this premium one and enjoy brighter, sharper images without replacing your telescope.

This star diagonal reflects the telescope's light path 90° to provide a more comfortable viewing angle. In addition, the glass has 58 layers of dielectric coatings, which provide an over 99% reflective surface, delivering the maximum amount of light to the eyepiece. The twist-lock eyepiece holder secures any 1.25" eyepieces while keeping them centered in the diagonal, thus providing best opto-mechanical alignment between the telescope and eyepiece. Unlike traditional thumb screws, the twist-lock cannot scratch or engrave the barrel of your eyepieces. The twist-lock has an integrated 1.25" barrel stop that prevents 1.25" accessories with long barrels from damaging the mirror.

All the diagonal's mechanical parts are made of machined black anodized aluminum, except the twist lock rings, which are orange anodized for visibility. The interior of the barrel is glare threaded and painted flat black to prevent glare. With all its features and these high-end finishes, the Celestron Dielectric Star Diagonal, 1.25" with Twist-Lock is one of the highest quality 1.25" star diagonals that Celestron has ever offered.

• Enjoy better views through your telescope with this premium diagonal featuring diffraction-limited optics and dielectric coatings
• Provides a 90° viewing angle, perfect for more comfortable viewing through refractor and Cassegrain-type telescopes
• 58 layers of dielectric coatings provide an over 99% reflective surface, ensuring the maximum amount of light collected by the telescope reaches the eyepiece
• Twist-lock keeps the eyepiece centered in the diagonal to provide better optical alignment
• Accepts standard eyepieces, Barlow lenses, threaded filters, and other accessories with a 1.25" barrel

Standard Star Diagonals vs Dielectric Star Diagonal

The key specifications for a star diagonal are its reflectivity and its optical quality. This diagonal delivers top performance in both categories, with an over 99% reflective mirror and diffraction-limited optical quality. This ensures that virtually all the light collected by the telescope will reach the eyepiece without the diagonal affecting optical performance. Using a lower quality star diagonal can both dim the view and degrade optical quality. You can enjoy better views from your telescope by simply swapping out its diagonal for a premium one, like the Celestron Dielectric Star Diagonal.

0615 4611 Pipe Wrap Probe NTC by Testo

For simple temperature measurements: use the temperature probe with Velcro with the compatible measuring instrument (please order separately) to measure the surface temperature of pipes.

Temperature probe with Velcro (NTC) - features and areas of application

Use the fixed cable including TUC connector to connect the pipe wrap probe (NTC) to the compatible measuring instrument. The temperature probe features a high-quality NTC sensor, which is attached to a 300 mm long strip of Velcro.

The temperature probe is designed for measuring the surface temperature of pipes and offers numerous application options. Thanks to the Velcro, it can be attached quickly and easily to pipes up to 75 mm in diameter. The temperature probe is therefore ideal for carrying out temperature measurements on water pipes or on the flow and return pipes of heating systems.

• Measuring range from -50 to +70 °C
• With Velcro, for easy attachment of the temperature probe to pipes up to 75 mm in diameter
• Temperature probe with NTC temperature sensor

Use the temperature probe with Velcro (NTC) (with the compatible measuring instrument) to carry out fast, easy measurements of the surface temperature of pipes.

Delivery Scope

1 x temperature probe with Velcro (NTC) with fixed cable (cable length 1.4 m).
