TS 0.8x field corrector for the CF-Apo 102mm f/7
The corrector is calculated for this apo and brings optimal astrophotographic results. Up to full frame cameras can be used and the star image is pinpoint in the corners. Also, the focal length of the apos is reduced to 571mm. The aperture ratio improves to f/5.6. Save about 36% exposure time compared to a 1.0x relaxer.
Connection of cameras to the corrector:
The corrector has an external thread M48x0.75 on the camera side. This thread offers 15% more illumination than T2. Therefore, we can recommend the corrector for all cameras up to full format. The working distance is exactly 55 mm from the thread. There are suitable adapters for this thread and this distance for all astronomical cameras. We are happy to help you.
The offset offers an intermediate thread M72x1 for individual adaptations, for example through M68x1 if you want to use a large off-axis guide, for example. We offer suitable adapters.
Thread for 2" nebula filter available:
If you unscrew the camera adapter from the corrector, it has a 2" filter thread inside. You can use fog filters to improve contrast or IR blocking filters. The working distance does not change.
The connection on the telescope side:
The corrector has an external thread M92x1 on the telescope side. You can use this thread to screw the corrector directly into the focuser of the TS CF Apos. This means that tilting is not possible and the star image remains optimal.
Adaptation of astronomical cameras with a distance of 17.5 mm from the T2 thread to the sensor:
Many astronomical cameras have a T2 connection thread and a 17.5mm back focus. With this adaptation you also have integrated 360° rotation, a quick coupling and a 2" filter holder. You need the following components from the camera to the telescope:
♦ T2AbstimmA05 (tuning ring with 0.5mm height)
♦ TSROTM48-T2 (adapter to M48, rotation, quick connector and filter holder)
♦ TSVF208 and TSFV210
