SVBONY SV550 Telescope 80mm Refractor Triplet Apo + SV209 1.0x Field Flattener. What is SV209?

SV209 1.0x Flattener Corrects the Field for Astrophotography M63x1 Connection Black.

*45mm large target effective field of view range, not only supports half frame camera, but also supports full frame camera;

*The built-in 2-inch filter installation thread supports the installation of 2-inch filter without purchasing filter drawer separately;

*Effectively improve the curved image quality of sv550 OTA edge field, while keeping the focal length and focal plane position of the objective lens unchanged.

Features:

*Connection at telescope side: M63x1Male thread;

*Connection at camera side: M48x0.75 male thread and M63x1 female thread;

*Working distances: 55 mm from the M48x0.75 external thread and 91.5mm (if you leave out the M63 extension);

*Maximum working distance from the M63x1 internal thread: 103 mm - space enough for almost all adaptations;

*M48x0.75 filter thread for the use of 2" filters in the camera adapter;

*The corrector does not change the focal length - factor 1.0;

*The position of the refractor´s focal plane is not changed;

*The corrector is suitable for SV550 80F6.

what is the function of sv209?

It is a special flat field mirror developed for SV550 80F6 OTA, which can effectively improve the image quality of SV550 OTA edge field, while maintaining the focal length and focal plane position of the Objective lens. The sv209 is equipped with M63 extension cylinder and M48 adapter ring to ensure that the rear intercept of the flattener is the astronomical conventional 55mm length.

• Deep sky photography OTA
• The SV550 APO Triplet refractor with 80mm aperture and fast f/6 focal ratio, a great travel telescope for observation and astrophotography.
• 4 extinction bars are designed to meet your ultimate pursuit of extinction.
• The structure of the triplet apochromatic optics effectively improves the blue-edge chromatic aberration at the edge.
• 180mm hollow-out super-long dovetail plate, which is convenient for customers to quickly balance the system.
• CNC double hinge opening hoop, easy to disassemble and install (built-in white felt, does not damage the outer wall of the lens barrel).
• Combining the SV550 Telescope with the SV405CC deep space camera, field flattener, CAA, soft case, and handle bar enables deep sky photography.

•  Apochromatic triplet uses a series of three lenses. It provides better correction of aberration and significantly reduces dispersion. It reduces chromatic aberration, and it corrects for two wavelengths to reduce spherical aberration. The apochromatic triplet objective provides high-quality, sharp and high-contrast images.
