SVBONY SV550 APO Triplet Refractor OTA 80 F6 Astronomy Telescope Set for Deep Space Astrophotography

APO Structure

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.

Elimination of Stray Light

Blackened inside and knife-edge baffle are for reduction of stray light and improvement of image contrast. 

Why should SV209 be used together with SV550？

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

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.

• Feature

• 1. Functional parameters overall part specification 5 political serial number specification parameters objective lens aperture 80mu;
• 2. Lens face type 1 / 8 wavelength;
• 3. The three piece APO compound achromatic objective lens structure is adopted to significantly improve the image quality of the captured image (increased by 15.8% according to the calculation of the spectrometer);
• 4. The 2.5-inch magnesium alloy double speed toothed focusing seat is adopted to reduce the vignetting of connecting the full frame camera and reduce the load weight of the support platform;
• 5. Multi process extreme extinction: multi-channel light bar extinction inside the focusing seat + inner wall of the lens barrel;
