Let’s Dive into Celestron EdgeHD 800 8″ Optical Tube Assembly 91030-XLT, OTA Telescope

The Celestron EdgeHD 800 8″ Optical Tube Assembly 91030-XLT, OTA Telescope represents a significant leap in amateur astronomy. It’s an investment, yes, but one that promises exceptional views of the cosmos. Celestron, a name synonymous with quality telescopes, has packed this OTA with features designed to deliver flat-field images and sharp details.

As someone who’s spent years peering through various optical instruments, I was searching for an OTA that could deliver astrograph-quality images without breaking the bank. I wanted something that would allow me to push my astrophotography further. The EdgeHD 800 caught my eye due to its reputation for delivering edge-to-edge sharpness.

The unboxing experience was straightforward. The OTA arrived well-protected. My initial impression was of solid build quality; the aluminum tube felt robust and the StarBright XLT coatings on the optics were visibly impressive.

Compared to my older Schmidt-Cassegrain telescope, the EdgeHD 800 immediately felt more refined. I considered a competing refractor known for its excellent contrast, but the aperture and portability of the Celestron won me over. The EdgeHD 800 provides a good balance between size, light gathering capability, and image quality.

My first impression was excitement tempered with a touch of nervousness. This was a significant upgrade, and I was eager to see if it would live up to the hype. The promise of sharper images across a wider field was incredibly appealing.

Real-World Testing: Putting Celestron EdgeHD 800 8″ Optical Tube Assembly 91030-XLT, OTA Telescope to the Test

First Use Experience

My first light with the EdgeHD 800 was at a remote dark sky site known for its minimal light pollution. I mounted it on my existing equatorial mount. I tested it on M42, the Orion Nebula.

Even through moderate seeing conditions, the nebula revealed intricate details that were previously hidden. The flatness of the field was immediately noticeable, with stars appearing sharp even near the edge of my wide-field eyepiece. Using a Baader Hyperion eyepiece, I was rewarded with beautiful views.

The only minor issue was the initial cool-down time. The large mirror took a while to reach thermal equilibrium. This is normal for SCT designs.

Extended Use & Reliability

After several months of regular use, the EdgeHD 800 continues to impress. It has proven to be a reliable workhorse for both visual observing and astrophotography. The views of globular clusters like M13 are stunning.

The OTA has held up well to transport and handling. There are no signs of any significant wear and tear. I make sure to store it in a padded case when not in use.

Cleaning the optics is relatively straightforward; I use a gentle microfiber cloth and lens cleaning solution. Collimation has remained stable, only requiring minor adjustments after transportation. Compared to my older telescope, the EdgeHD 800 delivers consistently superior image quality. It’s a worthwhile investment for serious astronomy enthusiasts.

Breaking Down the Features of Celestron EdgeHD 800 8″ Optical Tube Assembly 91030-XLT, OTA Telescope

Specifications

• Optical Design: Aplanatic Schmidt-Cassegrain. This design provides a flat field of view, essential for astrophotography and pleasing to the eye visually.
• Aperture: 203.2 mm (8 inches). An 8-inch aperture offers a significant light-gathering capability. This allows you to observe fainter deep-sky objects.
• Focal Length: 2032 mm (80 inches). A long focal length translates to high magnification potential, ideal for planetary viewing.
• Focal Ratio: f/10. The f/10 focal ratio provides a good balance between image scale and exposure time.
• Finderscope: 9×50. This finderscope is sufficient for locating objects in the night sky.
• Optical Tube: Aluminum. The aluminum construction keeps the OTA relatively lightweight while maintaining structural integrity.
• Optical Coatings: StarBright XLT. These coatings significantly improve light transmission. This results in brighter images.
• Optical Tube Length: 17 inches (431.8 mm). The compact optical tube length enhances portability and ease of handling.
• Optical Tube Weight: 14 lb (6.35 kg). The weight is manageable for most equatorial mounts.
• Dovetail Compatibility: CGE Mount. The CGE dovetail makes it compatible with a wide range of mounts.

Performance & Functionality

The Celestron EdgeHD 800 excels at delivering sharp, high-contrast images across a wide field of view. Its aplanatic design minimizes aberrations, especially at the edge of the field. The scope also features mirror support knobs.

The OTA’s strengths lie in its ability to resolve fine details on planets and deep-sky objects. The only weakness is its slow f/10 focal ratio, which requires longer exposure times for astrophotography. It generally exceeds expectations.

Design & Ergonomics

The build quality is excellent. The OTA feels solid and well-constructed. The internal focusing mechanism is smooth and precise.

The OTA is relatively easy to use. Some experience with telescopes is helpful, but the learning curve is not steep.

Durability & Maintenance

With proper care, the EdgeHD 800 should last for many years. The aluminum tube is resistant to corrosion. The StarBright XLT coatings are durable and long-lasting.

Cleaning the optics requires a gentle touch. However, it is a straightforward process. Collimation is also relatively easy to perform.

Accessories and Customization Options

The Celestron EdgeHD 800 comes with a 40 mm eyepiece, a 9×50 finderscope, and a visual back. The most popular accessories are focal reducers.

The OTA is also compatible with a wide range of eyepieces, diagonals, and cameras. The Fastar compatibility is a notable feature. It allows for ultra-fast f/2 imaging with optional accessories.
