Solar Filter for 102 mm Refractors

The Celestron EclipSmart Solar Filter fits StarSense Explorer DX 102AZ and Omni XLT AZ 102 telescopes. It uses scratch-resistant polymer film from American Paper Optics to block 99.999 % of intense visible light plus infrared and ultraviolet radiation. The filter provides a 53 mm clear aperture for detailed orange-hued views of the solar surface. Three nylon safety screws lock the assembly firmly to the optical tube.

Suitable Scopes and Limitations

This accessory is made exclusively for the two listed 102 mm refractor models with 120 mm outer and 117 mm inner diameters. Owners of other Celestron telescopes or different aperture sizes cannot use it. Buyers who want a full-aperture filter larger than 53 mm or a filter for a different brand should look elsewhere.

Critical Fit Specification

The filter requires a telescope front cell with a 117 mm internal diameter and 120 mm external diameter. Measure your tube carefully; if those dimensions do not match, the safety screws cannot secure the filter and it will not mount safely.

It fits the StarSense Explorer DX 102AZ and Omni XLT AZ 102 refractors, matching their 120mm external and 117mm internal diameters.

Will the three nylon safety screws hold the filter on my existing 102mm Celestron refractor without modification?

Yes, the screws secure the filter to the 120mm outer diameter of those two models, preventing accidental dislodging during solar sessions.
