Let’s Talk About Celestron EdgeHD .7x Telescope Reducer Lens, 14in – 1 out of 2 models
As an avid astrophotographer, I’ve always been on the hunt for ways to maximize the capabilities of my telescopes. The Celestron EdgeHD .7x Telescope Reducer Lens, 14in – 1 out of 2 models promised to be a game-changer, offering a wider field of view and faster exposure times with my Celestron EdgeHD 14-inch telescope. I was eager to see if it lived up to the hype, especially considering its price tag.
My biggest hurdle was capturing wide-field images of deep-sky objects with my EdgeHD 14. The telescope’s native focal length made it challenging to image large nebulae and galaxies. I needed something to effectively shorten the focal length and increase the field of view.
The reducer arrived well-packaged. My initial impression was positive; the lens felt solid and well-constructed. It was noticeably heavier than I expected, indicating the quality of the glass and metal used.
I considered other reducer lenses from Astro-Physics and Tele Vue, but I chose the Celestron model because it was specifically designed for the EdgeHD series. This ensured optimal compatibility and image quality. I was cautiously optimistic, hoping it would transform my astrophotography workflow.
Real-World Testing: Putting Celestron EdgeHD .7x Telescope Reducer Lens, 14in – 1 out of 2 models to the Test
First Use Experience
My first testing session was at a dark sky site in the Mojave Desert. I attached the Celestron EdgeHD .7x Telescope Reducer Lens, 14in – 1 out of 2 models to my EdgeHD 14-inch, connected my CCD camera, and targeted the Andromeda Galaxy. The process was surprisingly straightforward.
The difference in field of view was immediately noticeable. The Andromeda Galaxy, which previously barely fit in the frame, now had plenty of room to breathe. Exposure times were also significantly reduced, saving me valuable imaging time.
The initial images revealed some slight vignetting in the corners, which I later corrected during processing. Other than that, the image quality was impressive. I was pleased with the increased speed and field of view.
Extended Use & Reliability
After several months of consistent use, the Celestron EdgeHD .7x Telescope Reducer Lens, 14in – 1 out of 2 models has become an indispensable part of my astrophotography setup. It consistently delivers excellent results. I’ve imaged numerous deep-sky objects with it, from the Orion Nebula to the Pleiades star cluster.
The lens has held up remarkably well. There are no signs of wear or tear, even after numerous setups and teardowns. The machined aluminum housing feels robust and durable.
Maintaining the lens is simple. I occasionally clean the glass surfaces with a microfiber cloth and lens cleaning solution. It’s essential to store it in a dry environment to prevent fungus growth. Compared to my previous attempts at wide-field imaging with a different telescope, the Celestron reducer is a vast improvement.
