TS CF-APO 180 mm f/7 FDC100 Triplet Apochromat
This large apo is a jewel in any observatory. It is the largest apo in our CF series and one of the largest mass-produced achromats in our range. With a weight of 19 kg, the apo needs a stronger mount, such as the CGX-L from Celestron, the GM2000 from 10Micron or the EQ8 from Skywatcher.
Astrophotography with the TS CF-Apo:
The large 180 mm CF-APO with the 4.2" RAP focuser allows astrophotography at the highest level. All common 1.0x correctors can be connected to the focuser. With the optional 0.8x reducer/corrector, specially designed for the 180 mm apo, you get a perfectly corrected image field up to full frame at a fast f/5.6. This allows you to expose objects completely in just one night at high resolution. The corrector is linked in the accessories section.
The TS CF-APO lens
The powerful air-spaced triplet lens has two APO elements. One of them is made of FCD100, which is comparable to FPL53. The result is good chromatic correction despite the relatively fast f/7 focal ratio. The elements are of course adjustable and are optimally set before shipping.
The mechanics of the TS CF-APO
Just as important as the lens is the mechanics. The sturdy tube has inner baffles for the best possible contrast. The 4.2" RAP focuser is designed for heavy loads, it works without tilting. The CNC tube rings are light but stable. A Losmandy style dovetail bar is attached to the base.
This is how we hand over the apo to the amateur:
Every single APO 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.Technical Information
