TS-Optics Photoline 140mm f/6.5 Super Triplet Apo with 2 ED elements

TS-Optics 140mm f/6.5 Photoline Triplet Apo

This Apo is manufactured by Sharpstar for Teleskop-Service. The apochromat remains portable and ideal for mobile astrophotography. Of course, the apo is also a good telescope for the observatory. The 140mm aperture and false color free image due to the triple design allow for a wide range of applications.

The 3-element lens is fully adjustable. Two ED ultra-low dispersion elements enable an image without chromatic aberration. Even bright stars will not have a strip of color.

The apochromat with the large 4" rack and pinion focuser enables astrophotography at the highest level. With the 0.75x 3" reducer you can achieve nearly f/4.8 with full image field correction down to size format full frame. This allows you to easily expose an object in one night.

Telescope-Sservice tests each 140mm f/6.5 apo like this:

♦ The telescope is cosmetically checked and the mechanics (focuser) are optimally adjusted.

♦ The collimation is checked on the optical bench (autocollimation) and improved if necessary.

♦ A series of images is taken, which is included with each telescope. Extrafocal and intrafocal star image, focused star image, and a Ronchi image.

Connection of correctors for astrophotography

The apo offers a generous working distance, so you can work with the TSAPORED075 (0.74x reducer) and still focus.

If you want to retrofit the TSFLAT25DEL (Flattener 1.0x), you need the following components.

♦ M68a-M63i - adapter to extend the M63 thread of the corrector to M68x1.

♦ 2 x TSVM6815 30mm M68x1 extensions - for smooth focusing. The extensions are placed between the M68x1 thread of the focuser and the adapter.
