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

TS-Optics 140 mm f/6.5 Photoline Triplet Apochromat

This apo is an ultimative telescope for observing and astrophotography. 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 allow 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.

This is how we hand over the apo to the star lover:

Every single TSAPO100Q is checked in our technical department before it is put into storage, in order to guarantee a consistently high product quality.

The mechanics are tested and the focuser is optimally adjusted.

The lens is cosmetically checked and cleaned. We also check that all counter screws are correctly tightened. These often loosen during transportation.

The optics are collimated and the result is checked on the optical bench. The telescope is given a serial number.

A complete star test is carried out, which is enclosed with the telescope (star images and ronchi image on the optical bench in autocollimation).

Only then are the telescopes handed over to the warehouse and prepared for dispatch.

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.

TSAPORED075 - 0.74x corrector up to full format
The corrector is specially calculated for this apo and brings a very good correction up to full frame format. The focal ratio is improved from f/6.5 to f/4.81. The corrector is screwed directly to the M88 internal thread of the focuser. The rotator on the camera side must be unscrewed for this purpose; the rotation then takes place via the 360° rotator on the telescope side. The working distance from the M48 thread on the camera side is 55 mm. The distance is extendable.

TSFLAT25G2 - 1.0x corrector up to full format
For those who want to use the full focal length of the telescope, this corrector is the optimal choice. This corrector can also be used up to full frame format. The corrector is screwed directly to the M68x1 female thread of the focuser. The working distance from the M48 thread on the camera side is 55 mm. The distance is extendable.

The combination of the Apo with the 1.0x TSFLAT25G2 will be my standard combination. The good speed of the Apo with f/6.5 makes a reducer not necessary and the correction is very good up to full frame. The setup with the ASI 2400 full frame camera worked from the beginning and I really enjoy it.
