High quality 4-element field corrector and focal length reducer for Celestron SC Schmidt Cassegrain telescopes.
♦ Easy Adaptation - Reducer bolts directly to the 2" SC thread on SC telescopes.
♦ The focal length is reduced by a factor of 0.63; this results in shorter exposure times by a factor of 2.5.
♦ The curved Schmidt-Cassegrain field of view is flattened, providing sharper stars throughout the field of view.
♦ TS Focal Reducer can be used excellently for photographic and visual purposes. The corrected field of view has a diameter of 24 mm.
♦ Long working distance of 85mm from the SC thread on the camera side - plenty of room for all adaptations.
♦ Attention, due to tolerances in the SC threads, not all connection adapters fit - more detailed information in the item description
TS Optics f/6.3 reducer and corrector for Schmidt-Cassegrain telescopes
This high quality corrector system has been specially developed for SC telescopes. With this 4-lens system, you can turn your Schmidt-Cassegrain telescope into a powerful telescope for astrophotography.
Product features and application areas of the TS f/6.3 SC corrector:
♦ The corrector fits all Celestron and Meade Schmidt-Cassegrain telescopes. It simply screws into the 2" thread on the back of the telescope.
♦ The f/6.3 corrector also has the SC thread on the eyepiece side. You can continue to use your accessories normally.
♦ The optimum working distance from the SC thread of the corrector is 85 mm. You can overshoot or undershoot the distance by up to 15% without any significant loss of quality.
♦ The focal length of SC telescopes is reduced by a factor of 0.63. A focal length of 2000mm converts to a focal length of 1260mm. The light intensity increases significantly. You can achieve the same saturation with only 40% of the exposure time compared to photography without a corrector.
♦ The optical correction system flattens the curved field of view of the Schmidt-Cassegrain telescope. This gives you a fully corrected field of view with a diameter of 24mm.
♦ The corrector also offers a visual enhancement, sharpness at the edges is improved and the field of view gain is significant. We recommend using the corrector with 1.25" eyepieces.
Astrophotography with off-axis guidance for tracking:
Due to the long focal length and large aperture of SC telescopes, we recommend off-axis guidance. This turns the logging telescope into a tracking telescope at the same time. We recommend the following adaptation:
♦ TSSC-M48 Adapter for SC thread corrector to M48 connector
♦ TSOAG27 off-axis guider and at the same time adapter to T2
Adaptation of the SC corrector to 2":
Many astronomers use a separate focuser on their SC telescope in order to focus more precisely and avoid "walking". We offer the appropriate adapter for this.
Not all SC female threaded camera side connection adapters will fit:
Unfortunately, the SC thread is subject to certain fluctuations. Straight plug adapters with a narrow internal SC thread will not fit. We have tested the following adapters and they fit:
♦ All Celestron adapters, such as 1.25" Visual Back CE821170
♦ The TS adapter in T2 and in M48 (TSSC-T2S and TSSC-M48)
♦ The following adapters do not fit: TSSC-2, TSSC-T2L, Baader adapter
