Neewer Silver 5.5" Full Aperture Mylar Material Safety Film Telescope Solar Filter

Features:

The Solar Filter is made with solar safety film, and yield bright, sharp images high in contrast.

The Solar Safety Film is clear and homogenous, attaining the optical performance of high quality plane-parallel glass filters, and is diffraction-limited. It is completely safe and durable, not breaking like glass if dropped.

The double-sided metal coatings have uniform density and good color balance across the entire field to ensure edge-to-edge sharp imagery.

When using the solar filter, the Sun appears in its real color neutral white-not blue or orange-and the sky adjacent to the solar limb is jet black. You will see detail in sunspots, bright faculae near the limb and the mottled areas known as granules.

The filter passes only a fraction of the incoming light, rejecting harmful ultraviolet and infrared radiation.

A must-have filter for safe observation of the sun through a telescope without damaging your eyes.

The filter is mounted in an aluminum cell that slide-fits over the front of your telescope. The aluminum cell features three equidistant securing thumbscrews.

Fits for Orion StarBlast 4.5 and SkyQuest XT4.5 reflectors, AstroView 120 and 120ST refractors, StarMax and Apex 127mm Maksutov-Cassegrain telescopes, and other models.
