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 2.5-inch focusing base can effectively reduce the vignetting problem when connecting to a full-frame camera, and the FPL51 APO can improve the quality of the captured images.
Note: This SV550 80 OTA comes with a dedicated dovetail slot for the finderscope, so you needn‘t to buy any accessories.
1.Rugged housing prevents damage;
2.Sliding graceful and soft dual-speed focuser;
3.Ed glass (FPL51) can produce very beautiful and clear images;
4.The fully multilayer coated lens eliminates all reflections on the glass, and it has little or no chromatic aberration at high magnification.

MK105 Maksutov-Cassegrain Telescope exchanges the conventional front corrector plate of a Schmidt with a convex meniscus lens, resulting in a smaller secondary mirror that limits obstruction and increases contrast, while eliminating the need for periodic collimation.
A perfect transportable, grab-and-go telescope, with its sturdy metal construction it will be sure to survive a few bumps and knocks on its travels.
Secondary Mirror with high Reflectivity with Dielectric Coatings, delivering 99% reflectivity.
