PrimaLuceLab 40mm/65mm Extension Tubes for ESATTO 3" (PL3600317/PL3600284)

PrimaLuceLab 40mm/65mm Extension Tubes for ESATTO 3" (PL3600317/PL3600284)When installing ESATTO 3" in a telescope with a long travel focuser (such as those usually found on refractors), it is necessary to take into account the lower travel of ESATTO 3" since it's a micrometric focuser. For this reason we have designed these extensions that can be installed between ESATTO 3" and the telescope tube. A precise dovetail coupling system with 3 screws set at 120 allows you to manually rotate the focuser.

this system of Baader Solar Filters™ is designed to retain the true optical quality of the diffraction limited AstroSolar Safety Film

Blocking range: 300-700nm

This diagonal also comes with two interchangeable barrels to provide flexibility in connecting the diagonal to a wide variety of telescopes without the need for additional adapters

4") Focal Ratio: f/2

for example by saving different values when you use different filters

This feature is very handy for remote controlling the camera in an observatory

allowing for easier transportation

Blocking: > 5 OD(0

the Celestron E-lux eyepiece is a 3-element

The Celestron Off-Axis Guider uses a prism to intercept a small portion of the telescope’s focal plane (outside the field of view of the main imaging camera) to locate a guide star

The EQ6 / Universal Tripod Adapter is used to build the 180mm Pier Extension for the NYX-101 mount from Pegasus Astro

finally you don’t need to adjust the equatorial level
