SVBONY SV550 APO Triple Refractor Telescope for Adults, 80mm F6 OTA, Portable Telescope for Deep Sky Astrophotography and Celestial Observation.

Revised Content:

The SV550 APO Triplet refractor boasts an 80mm aperture and a fast f/6 focal ratio, making it an excellent choice for travel, observation, and astrophotography. Its hollow-out standard dovetail plate allows for adjusting the distance between the two hoops according to the rear-end load, ensuring the balance of the entire system.

To eliminate any stray light interference within the lens barrel, this telescope employs a cutting-edge extinction process, utilizing four extinction light bars inside the barrel. This innovative design effectively eradicates any potential issues caused by internal reflections.

Designed to handle a payload of up to 10KG, the SV550 can easily accommodate the MK105 telescope, providing a stable and secure platform for your observation and imaging needs. The adjustable all-round viewing angle, coupled with the helical turbine drive, offers a 360° rotation and a -60° to +60° altitude adjustment, allowing you to observe the heavens with unparalleled flexibility.

Addressing the common issue of fine focus control, the SV550 features a fine-tuning control lever that enhances your adjustment efficiency in different scenarios, ensuring a seamless and precise focusing experience.

The optical design of the SV550 is a true marvel, employing a triplet apochromatic structure. This configuration, which combines one piece of S-FPL51 low-dispersion ED glass and two pieces of correction glass, significantly improves the image quality by reducing edge dispersion and minimizing blue fringing problems. Spectrometer calculations indicate a 15.8% increase in image quality compared to single-ED structures.

Specifications: - Model: SV550 - Resolution: 1.45 arc seconds - Telescope Type: Refractor - Lens design: Triplet apochromatic optics - Coating: Fully Multi-coated - Focal Length: 480mm - Aperture: 80mm

The SV225 alt-az mount, which is compatible with the SV550 OTA, boasts a maximum additional load capacity of 10kg, a V-style mounting saddle, and a UNC 3/8 -16 female thread underneath the base. It offers an impressive altitude rotation angle of -60° to +60° and a full 360° azimuth rotation, providing excellent versatility for your celestial observations.

The fine adjustment capabilities of the SV225 mount, combined with its variable speed gear controls on both axes, allow you to smoothly track the motion of the moon and planets, ensuring a seamless and precise viewing experience.

Whether you're exploring the Messier catalog, the iconic M42 and M45 targets, or any other celestial wonders, the SV550 APO Triplet refractor, paired with the SV225 alt-az mount, is a powerhouse that will reveal the true beauty and complexity of the night sky, with stunning clarity and exceptional performance.
