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

The 140 mm f/6.5 triplet apochromat convinces with a pure color image and a powerful 4" RAP focuser.

♦ Aperture 140 mm

♦ Focal length 910 mm

♦ Fast focal ratio f/6.5

♦ Air-spaced triplet objective - 2 ED elements provide an image free from chromatic aberration

♦ Solid 4" rack and pinion focuser with dual speed - ideal for astrophotography

♦ Intermediate threads for screwed adaptations, e.g. M68x1 female thread

♦ Retractable dew shield

♦ CNC tube rings, carrying handle and dovetail bar are included in the scope of delivery

♦ Delivery in transport case

♦ Every apochromat is tested by the manufacturer and Teleskop-Service before shipment

♦ Each apo receives a serial number and is delivered with a photographical test certificate

 

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.
 

So telescope service tests every 140 mm f/6.5 apo:

♦ 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.

TSAPORED075 - 0.74x corrector up to full formatThe corrector is specially calculated for this apo and brings a very good correction up to full 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 working distance from the M48 thread on the camera side is 55 mm. The distance is extendable.

TSFLAT25G2 - 1.0x corrector up to full formatFor 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 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.
