Let’s Dive into Celestron EclipSmart Solar Filter, 70mm Refractor PS70AZ/EQ, TS70
The Celestron EclipSmart Solar Filter, 70mm Refractor PS70AZ/EQ, TS70 isn’t just an accessory; it’s a gateway to safely witnessing one of nature’s most awe-inspiring events. Manufactured by Celestron, this filter is specifically designed for their PowerSeeker 70 AZ/EQ and Travel Scope 70 telescopes, transforming them into safe solar viewing instruments. Its ISO-compliant solar safe film and secure mounting system promise both safety and an unforgettable experience.
As a seasoned outdoor gear enthusiast, I’ve always been fascinated by celestial events, particularly solar eclipses. Living in an area where the next partial eclipse will be visible, I wanted a safe and reliable way to share the experience with my family and friends, particularly my young children. The Celestron EclipSmart Solar Filter seemed like the perfect solution to adapt our existing Travel Scope 70 for this purpose.
Upon unboxing, the filter felt surprisingly lightweight yet sturdy. The Celestron proprietary Mylar filter material appeared taut and free of any defects. The included nylon safety screws gave me confidence in its ability to securely attach to the telescope.
Compared to standalone solar viewing glasses, the EclipSmart Solar Filter offered the potential for a magnified view, enhancing the details visible on the Sun’s surface. Other universal sheet-type filters required cutting and potentially clumsy mounting, making the Celestron EclipSmart a much cleaner and safer option for telescope use. My initial impression was one of cautious optimism—excited about the possibilities, but keenly aware of the responsibility involved in safe solar viewing.
Real-World Testing: Putting Celestron EclipSmart Solar Filter, 70mm Refractor PS70AZ/EQ, TS70 to the Test
First Use Experience
My first test of the Celestron EclipSmart Solar Filter took place on a clear, sunny afternoon in my backyard. With the Travel Scope 70 set up, I carefully attached the filter using the three nylon safety screws, ensuring a snug and secure fit. The process was straightforward, taking only a few minutes.
The view through the telescope with the filter was a remarkable yellow-orange disc. Sunspots were clearly visible as small, dark blemishes against the bright solar surface. There was no noticeable glare or distortion, and the filter effectively blocked out the intense visible light.
The biggest surprise was the ease of achieving focus. The filter did not significantly alter the focal point of the telescope. My kids were mesmerized, taking turns observing the Sun with a newfound appreciation.

After several weeks of occasional use, the Celestron EclipSmart Solar Filter has held up exceptionally well. There are no signs of wear or tear on the filter material or the housing. The nylon safety screws remain secure, even after repeated attachment and detachment.
Cleaning is simple. A gentle wipe with a microfiber cloth removes any dust or smudges from the filter surface. Compared to my previous attempts at projecting the sun’s image (a method I quickly abandoned due to safety concerns), the EclipSmart offers a far superior, and safer, viewing experience.
The Celestron EclipSmart Solar Filter has consistently delivered clear, safe solar views. It outperforms any other method I’ve tried for observing the Sun. It has made sharing astronomical events with my family a truly enjoyable and educational experience.
