TS-Optics Photoline 140 mm f/6.5

Codice articolo: TSAPO140

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 cap
• ♦ 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 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.

So telescope service tests every 140mm 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.
