Let’s Dive into Explore Scientific 3in Diagonal Mirror
The Explore Scientific 3in Diagonal Mirror isn’t just another accessory; it’s a crucial component for any serious astronomer seeking to maximize their telescope’s performance. Priced at $589.99, this diagonal boasts a 99% enhanced mirror coating, promising exceptional light transmission and image clarity. Explore Scientific aims to deliver professional-grade viewing, and I was eager to see if this diagonal lived up to the hype.
I’ve been a dedicated amateur astronomer for years, and one of my biggest frustrations has always been light loss and image degradation through the diagonal. I’ve tried various diagonals, always searching for that perfect balance of light throughput, image sharpness, and build quality. This product’s claims of a 99% reflective mirror piqued my interest and I knew I had to test it myself.
Upon unboxing the Explore Scientific 3in Diagonal Mirror, my first impression was one of solid construction. The weight felt substantial, indicating quality materials. The black finish was sleek and professional, and the included 2″ eyepiece adapter was a welcome addition.
Compared to my existing 2″ dielectric diagonal and a cheaper, older 1.25″ prism diagonal, the Explore Scientific 3in Diagonal Mirror stood out immediately. The build quality felt far superior to the prism diagonal, and the larger 3″ aperture promised to minimize vignetting, a common issue with smaller diagonals, especially when used with wide-field eyepieces. I chose this diagonal over others primarily due to its aperture and the promise of minimal light loss.
My initial excitement was high. The promise of brighter, sharper images was a significant draw. I was cautiously optimistic, hoping this would be the final piece in optimizing my telescope’s performance.
Real-World Testing: Putting Explore Scientific 3in Diagonal Mirror to the Test
First Use Experience
My first test of the Explore Scientific 3in Diagonal Mirror was at my usual dark-sky location, about an hour outside the city. The skies were clear, with minimal light pollution. I paired the diagonal with my 10″ Schmidt-Cassegrain telescope and a range of eyepieces, from a high-power planetary eyepiece to a wide-field deep-sky eyepiece.
The difference was immediately noticeable when viewing Jupiter. The image was noticeably brighter and sharper compared to my 2″ dielectric diagonal. The contrast was also improved, allowing me to see subtle details in the Jovian cloud bands that I hadn’t noticed before.
Ease of use was excellent; the diagonal slipped smoothly into the telescope’s focuser, and the 2″ eyepiece adapter held my eyepieces securely. I experienced no issues with collimation or focusing. The larger aperture allowed me to use my widest field of view eyepiece without vignetting.
Extended Use & Reliability
After several months of regular use, the Explore Scientific 3in Diagonal Mirror continues to impress. It has become an integral part of my observing setup. The views remain consistently bright and sharp.
Durability has been excellent; the diagonal shows no signs of wear and tear despite being transported regularly to different observing sites. The mirror coating appears to be robust.
Maintenance has been minimal; I simply wipe the mirror occasionally with a microfiber cloth to remove any dust or fingerprints. The black anodized finish cleans easily with a damp cloth.
Compared to previous diagonals, the Explore Scientific 3in Diagonal Mirror significantly outperforms them in terms of light throughput and image clarity. My old 1.25″ prism diagonal is now relegated to storage. The Explore Scientific is well worth the investment.
