Superior Performance

1. The APO triplet refractor features a 122mm aperture and 854mm focal length,which is an absolutely upgraded version of the SV550 80mm. The refractor gathers more light, and offers more clear and detailed images, suitable for deep sky photography and observation, for galaxies, nebulae, star clusters and even some fainter deep sky objects, due to the higher limiting magnitude. 

2. 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.

3. The length of the dovetail is  as high as 300mm, longer than the length of most dovetails. It can maintain the balance to the greatest extent, and it will be more convenient in the adjustment process.

4. The entire tube rings have 26 screw holes + a mounting screw handle. Such tube rings with so many screw holes can be compatible with more equipment installations, like Smart WIFI device, guide scope, astronomy camera etc., meeting various needs of installations.

For EAF Installation

This SV550 122 APO is compatible with EAF focuser. To install the EAF, first you should remove the screw completely as shown. Then look inside the hole and slowly rotate the focuser until you see another set screw inside the hole. This screw actually secures the focusing knob to the shaft. Insert a wrench and loosen this screw. Note that there may be two of these screws, so rotate the focusing shaft one turn to be sure. The focus knob will slide off after that.
