TS-Optics Photoline 140 mm f/6.5 Super Triplet Apo with 2 ED elements
TS-Optics 140 mm f/6.5 Photoline Triplet Apochromat
This Apo is manufactured by Sharpstar for Teleskop-Service. The apochromat is still portable and ideal for mobile astrophotography. Of course the apo is also a fine telescope for the observatory. 140 mm aperture and the image free of false color due to the triplet design allow a wide range of applications.
The 3-element objective is fully adjustable. Two Ultra-Low Dispersion ED elements enable an image free of chromatic aberration. Even bright stars will not have a color fringe.
The Apochromat with the large 4" rack and pinion focuser allows astrophotography at the highest level. With the 0.75x 3" reducer you can achieve fast f/4.8 with full correction of the image field up to full frame size format. This allows you to expose an object easily in one night.
