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.

Telescope-Sservice tests every 140 mm f/6.5 apo this way:

♦ The telescope is checked cosmetically and the mechanics (focuser) is adjusted optimally.
♦ The collimation is checked at the optical bench (autocollimation) and improved if necessary.
♦ A series of images is taken, which is included with every telescope. Star image extra- and intrafocal, star image in focus and a Ronchi image.

Connection of correctors for astrophotography
The apo offers a generous working distance, so that you can work with the TSAPORED075 (0.74x reducer) and still get into focus.

If you want to adapt the TSFLAT25DEL (1.0x flattener), you need the following components.
♦ M68a-M63i - adapter to extend the M63 thread of the corrector to M68x1.
♦ 2x TSVM6815 30 mm M68x1 extension - to get into focus without problems. The extensions are positioned between the M68x1 thread on the focuser and the adapter.
