93669 Nebula Filter for Celestron Origin by Celestron

• Get the Most Out of Your Origin: Enhance your Celestron Origin's views and images of nebulae—especially from urban and suburban skies. This filter blocks light pollution, boosts image contrast, and darkens the sky background for noticeably better images.
• Nebulae Come to Life: This filter transmits only the key Hα-Hβ-OIII wavelengths from emission nebulae, making their colors "pop" from the dark background.
• Conquers Light Pollution: With this filter, you allow the "good" wavelengths of light from nebulae through but block the "bad" light pollution from reaching Origin's sensor.
• Built for Origin's RASA Optics: Unlike similar filters with narrower bandpasses, this filter was engineered specifically to work with Origin's fast f/2.2 optics to allow more of the light you want while suppressing the light you don't.
• Easy Installation: Simply remove the optical window from Origin's filter drawer and insert the Nebula Filter. It won't disrupt the optical path of your Origin, and no additional adapters are needed.
• Quality Construction: Constructed of Schott glass with anti-reflective coatings, this filter's surfaces are optically flat and free from defects.

37804-13 Data Acquisition Software with USB Cable; For 98766-89/90/93/94, 91210-03, 90080-04, and 98767-11 by Digi-Sense

Complete Data Acquisition Software enables you to display and store measurement readings on your PC from up to 8 devices at a time. Data capture runs in the background, enabling you to work on other programs, simultaneously. Set audible and visual notification alarms or immediately send an email if a over/under condition occurs. The software can be used to connect a meter directly to your PC via cable, or coupled with the Digi-Sense Wireless Radio-Signal Transceiver Kit (37804-12). Check software specification tables for meter compatibility, or contact our application specialists if you have a meter with RS-232 output not listed in the tables.

• Compatible with any PC with Windows®
• Compatible with items 98766-89/90/93/94, 91210-03, 90080-04, and 98767-11

CO2 Solenoid Diaphram Valve by Milwaukee

Includes flow regulator, needle valve, electronic solenoid & bubble counter. Unit comes with dual gauges each with dual reading of both psi & kg/cm. Left gauge meters tank capacity and right gauge meters flow. Needle valve flow control provides for precise measurement.

The solenoid valve comes with a 1.5 meter power cord. (CO2 bottle is not included)

Recommended best if used with our MC122 pH Controller.

98766-88 Traceable Relative Humidity Meter with Dew Point and Calibration by Digi-Sense

This pocket-sized thermohygrometer measures full-range relative humidity, temperature from -4 to 122°F (-20 to 50°C), and calculates dew point. Compact design features an electronic capacitance polymer film sensor - not affected by condensation.

Quickly recall minimum and maximum RH and temperature values, and freeze data readings with the press of a button. The dual-line display simultaneously shows humidity and either current or dew point temperature. Unit turns off automatically after 20 minutes of non-use to conserve battery life.

Traceable® Products have an individually-numbered Traceable® Certificate provided with each unit, that assures accuracy from our ISO/IEC 17025:2017(1750.01) calibration laboratory accredited by A2LA. It indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMI) that are signatories to the CIPM Mutual Recognition Agreement. Each product goes through an intense vetting process before it can carry the Traceable name, thus saving you both time and money by not having to calibrate separately.

• Includes NIST-Traceable certificate from our A2LA accredited (1750.01) calibration laboratory
• Full-range response time less than 1 minute
• Sensor is not affected by condensation - measure up to 100% RH

Includes

Two AAA batteries, probe cover, and NIST-traceable calibration certificate with data.
