Takahashi TSA-120 on EM-200 Temma-2M
Intermediate instrument between the TSA-102, of which it takes again the main features, and the TOA-130, TSA-120 refractor replaces the famous FS-128. The TSA-120 is characterized by its simplicity, its versatility and his exceptional quality/price ratio.
TSA-120 features the specifications of the TSA-102S : an apochromatic objective with triplet ED, a retractable dew-shield, great mechanics and versatility of use, both visual and photographic. Moreover, TSA-120 is extremely light, it weights only 6.7 kg. Even when TSA-120 is fully equipped for CCD imaging, EM-200 will easily holds it. No extra heavy mounts will be required.
This refractor can be equipped with the same optical accessories as the TSA-102, including the focal reducer TOA-RD #18, the field corrector TOA-FL35 and ED 1.5x and TOA 1.6x extenders. The specific system-charts will help you to specify the necessary configurations.
Mount Description:
The EM-200 is a German equatorial mounting providing a stable support for any telescope up to 15 kg without the accessories (load limits 18kg, except counterweight). For example, Mewlon-210, CN-212 or TOA-130 OTAs will be comfortably exploitable with their equipment for astrophotography or CCD imaging. The couple of the motorization, more powerful than the old version, supports the use of the strong loads cantilever.
The EM-200, with an ergonomic design and particularly adapted to the hard night conditions, was designed to face the most extreme visual and photographic challenges. RA/DEC motors are totally integrated inside the mount not laying outside any components that are easily lost during night observation. Strict assembly and use of high performance mechanical pieces features Takahashi mounts with a periodic error of ± 5 arcsecond by turn, while competitors just do not provide such specification.
