TS-Optics REFRACTOR 0.8x corrector for refractors up to 102 mm aperture - ADJUSTABLE

Item condition: new, but not original packed

The Skywatcher 0.85x focal reducer / field flattener has been designed for astronomers who want to use the renown ED Apo for astro photography. The flattener reduces the telescope's focal length by the factor of 0.85 and increases the useful field. As a positive side effect, the necessary integration times are significantly reduced. The field curvature that is unavoidable at most telescope systems is reduced to a nearly irrelevant level when using sensors up to APS-C format (24x16mm). Optimal distance M48 - focal plane: 55mm

TS-Optics Twist-Lock adapter from 2" to 1.25" with filter thread - clamped as if screwed! The Twist-Lock system allows perfect clamping on the optical axis. Tilting of accessories is prevented which means irritating problems with the common combination "safety groove and ring clamping" belong to the past. By rotating the upper ring, it embraces the eyepiece or adapter whilst travelling 15 mm. A gentle tightening is sufficient to achieve a secure connection. The TSTW2-1 fits in every 2" eyepiece reception and cannot tilt itself, because it doesn´t have a safety groove. The adapter has a telescope-sided 2" filter thread (M48x0.75) for screwing in 2" filters.

0.77X REDUCER/FLATTENER FOR ESPRIT-150ED TRIPLET Designed specifically for the Sky-Watcher Esprit-150 ED Apo Refractor, the new three-lens Focal Reducer/Flattener has a reduction factor of 0.77x. It comes with a standard adaptor with M48 thread edge and 55mm back focus for use with Sky-Watcher's M48 Canon EOS (code 20237) and Nikon (code 20238) adaptor rings. After removing the adaptor, an M71x1 internal thread with maximum 75mm back focus is available for self-made adaptor solutions. The Reducer/Flattener produces a fully illuminated and corrected image circle of 34mm diameter and is therefore perfectly suitable for image formats up to APS-C but can also be used for full format.

TS Adapter for recessed adaptation of correctors in the focuser UNCN3M82 The TS V-Power focuser with the M82 threaded connection on the camera side accepts large correctors up to 3" body diameter. This adapter allows correctors to be connected via the M68x1 male thread on the corrector. The corrector is recessed into the draw tube, saving valuable optical path. Tilting, as is possible with clamping, is eliminated by the screw connection. On the camera side, the adapter has an M48x0.75 male thread for further adaptations. How the adapter works and what to consider: ♦ Screw the corrector into the M68x1 female thread of the adapter. ♦ Then screw the adapter with the corrector into the M82x1 female thread of the focuser. ♦ Please consider that the adapter needs 9 mm travel (length of the M68x1 female thread and overall length of the adapter) - these 9 mm must be subtracted from the working distance of the corrector. The advantage is that all larger correctors offer a longer working distance. Application example: TSKORW3 on a 325 mm f/4 Newtonian with this adapter: ♦ working distance of the KORW3 Wynne corrector is 64 mm ♦ 9 mm optical path to be subtracted - so 55 mm remain from the M48x0.75 male thread on the adapter. Ideal therefore for all photo adaptations ♦ The exact working distance can be established with suitable adaptations and tuning rings.
