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. Focal Length: 480mm The focal length is 480mm, suitable for deep sky observation and photography, for galaxies, nebulae, star clusters and other deep sky objects.; 2.5" 1:10 Dual-speed Focuser The gear ratio of the dual speed 2.5-inch toothed focuser is 1: 10, which makes it easy to achieve accurate focus. The dual speed focuser can provide two focusing speeds by using a set of co-axial knobs, for fast focusing and fine focusing. ; Elimination of Stray Light Blackened inside and knife-edge baffle are for reduction of stray light and improvement of image contrast. ; 2-inch & M63x1 Vixen-style Dovetail For astronomy enthusiasts, it is a very challenging and interesting thing to match various accessories and telescopes to photograph target objections. This can give full play to your imagination and creativity. On our social platform, there are often many fans sharing their collocations, which is really pleasing. So what can we match the SV550? Today I want to share with you two options. If you have better ideas, welcome to share them with us. Let me first introduce the product highlights of SV550： Point 1: The three-piece APO apochromatic objective lens structure is adopted, which significantly improves the image quality of the captured image (15.8% increase by the spectrometer measurement) Core selling. Point 2: 2.5-inch magnesium alloy dual-speed toothed focusing seat is used to reduce vignetting when connecting to a full-frame camera and reduce the load weight of the supporting platform. Point 3: extreme extinction, the interior of the focusing seat + the inner wall of the lens barrel with multiple light barriers. Point 4: The dedicated 1x flat field mirror is launched simultaneously to meet the ultimate pursuit of image quality for deep space photography users (the synchronization accessories also include CAA handles and portable storage bags). If you want to use these equipment for photography, you can consider these combinations.
