Deep sky photography OTA


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.


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.


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. Magnesium alloy focusing seat, compared with aluminum alloy materials of the same specification, the weight can be reduced by more than 20%, reducing the load


Extreme Extinction

4 extinction light bars are used inside the lens barrel, which can eliminate all stray light interference on the inner wall of the lens barrel.

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.



SV210 M63 CAA 360 Degree Rotator Camera angle Adjuster for Visual Rotation Black

The image field rotator of sv210 CAA camera is mainly used for astronomical photography scenes.


SV191 super-wide-angle 1.25'' zoom eyepiece 7.2-21.6mm and 9mm-27mm, allow you to change magnification power without swapping out eyepieces.



  • Combining the SV550 80 APO with the SV405CC deep space camera, SV209 field flattener, SV210 CAA, SV191 Zoom Telescope Eyepiece and a SV211 135mm Handle Bar, enables deep sky vision and photography perfectly.
