TS Optics 100mm ED Apo Refractor... aperture 100mm - focal length 600mm - f/6
... fast apochromatic refractor for observation and photography

The optical and mechanical quality of this ED refractor conviced us at the first glance. The multi coated ED objective delivers a bright and high-contrast picture and pinpoint stars. The chromatic abberation is surprisingly low so we can recommend this system not only for deep-sky observation but also for astro photography. Even the Moon and Planets can be observed with good contrast.

This refractor is ultra compact:
Thanks to the retractable dew cap, the transport length of this telescope is only 55cm. So it is very suitable for travelling. It comes with a robust aluminium transport case with enough space for additional accessories.

The TS Apo 1006's fast focal ratio:
With a photographic speed of f/6, this refractor is faster than most of the competitors we know. The f/6 system offers many advantages: The usable field is wider (especially for photography), the necessary esposure times are shorter and need therefore less care for guiding. We recommend our TS Optics 2" and 2.5" field flattener.

Advantages of the TSAPO1006:

-- high quality ED objective with 100mm aperture and 600mm focal length
-- fast f/6 photographic speed for short exposure times
-- very compact (55cm) thanks to retractable dewcap
-- 2.7" linear power focuser. Stiffer and more precise than the Crayford design, illuminates even bigger sensors
-- 1:11 dual speed focuser transmission
-- CNC machined tube rings
-- useful and robust aluminium travel ca

Technical details:

The 2.7" Linear Power focuser:



With such a fast system, a bigger focuser becomes necessary in order to prevent vignetting (as it would appear with a 2" focuser). It also offers the following advantages:

-- 2.7" free aperture
-- massive side-beared steel rail with additional ball bearings for the drawtube
-- No shifting due to steel mono rail
-- 1:11 micro transmission for fine focusing (essential for photography)
-- 360° rotation system for the whole focuser and separately for the 2" adapter
-- 2" and 1.25" adaptation with solid brass clamping ring

Scope of delivery:




-- 100/600mm ED APO with 2.5" focuser
-- Reducers for 2" and 1.25"
-- CNC tube rings
-- Aluminium transport case

Optional Accessories:

TS 2" Flattener and Adapter kit (199 € only when purchased together with this telescope):



This fast ED Apo is ideally suited for astro photography. To correct for the field curvature that is inherent with nearly any telescope, we offer a specially designed field flattener. It has no focal reduction so the main attention could be put on the flattening performance. It offers a field illumination up to 30mm and is therefore superior to to most 0.8x reducers.
-- TSFLAT2: 2" Flattener
-- TSFA2: Adapter to T2
-- TSVF25: M48 extension, 25mm
-- 2" counter ring

TS 2.5" Flattener for full-size sensors:



Recommended for cameras with sensors larger than APS-C.

To connect this flattener with this telescope, you need the adapter "M74-Flat25". The optimal back focus discance here is 102 mm.
