See the Sun safely!
View the Sun in safety with the Celestron solar filter for NexStar 4 telescopes.
New Celestron solar filters are made with Baader Astro Solar Safety Film. Astro Film is clear, homogenous and attains the optical performance of high-quality, plane-parallel glass filters. Teamed with double-sided, uniform-density, metal lens coatings, it produces brighter, sharper and more contrast-rich images than the competition.
As a result, the Sun will appear in its "real" neutral white color -- not blue or orange -- and the sky adjacent to the solar limb will be jet black. You'll see detail in sunspots, bright faculae near the limb and the mottled areas known as granules with these filters.
Celestron's solar filter is completely safe and durable (won't break like glass if dropped). Its film rating is ND-5 which means that it transmits 1/100,000 of visible light (.001%) while reflecting (blocking) 99.999% of unwanted light, and it has been declared safe for direct solar viewing by the German National Bureau of Standards for eye safety.
The Sun offers constant changes and will keep your observing interesting and fun. You'll see all it has to offer in safety with the Celestron solar filter for NexStar 4 telescopes!
