TS PHOTOLINE 1.0x field corrector for APO and ED refractor telescopes
This corrector is suitable for refractors from 80 mm aperture. It works very well with the PHOTOLINE apos and with the ED refractors from 80 mm aperture from TS-Optics. The corrector offers very good illumination and correction up to 45 mm diameter (image circle) and can thus be used very well on cameras with full-frame sensors.Adjust the corrector individually to your camera and your refractor - no more adapter battle!
An essential part of the corrector is an integrated fine adjustment. By turning the knurled ring on the corrector, you can adjust the distance to the sensor to within fractions of a millimeter. Once you have reached the desired distance, fix it with the locking screw. In this way, you can determine the optimum distance via test exposures with the camera connected, without additional adapters and tuning rings. The camera does not rotate during fine adjustment.The following settings from the innermost position of the adjustment to the sensor are recommended:
Connection to telescope:
- Aperture 80 mm / focal ratio f/6 - 81.2 mm
- Aperture 80 mm / focal ratio f/7 - 80.2 mm
- Aperture 102 mm / focal ratio f/7 - 75.3 mm
- Aperture 115 mm / focal ratio f/7 - 73.0 mm
- Aperture 130 mm / focal ratio f/7 - 69.7 mm
- Aperture 140 mm / focal ratio f/6.5 - 68.0 mm
- Aperture 155 mm / focal ratio f/8 - 57.0 mm
This Photoline reducer has a M63x1 male thread on the telescope side. Many focusers already have this thread as standard. Adapters to other threads, such as M68x1, are of course available.Application example - how to set the distance:
Setting the correct distance is very easy, as we show it with the following example:Telescope:
refractor with 130 mm aperture f/7, i.e. 910 mm focal length.
Camera: SLR with 55 mm distance from M48 thread to sensor.
The working distance is 69.7 mm according to the table. From this measurement, simply subtract the 55 mm (distance thread to sensor). This leaves 14.7 mm.
Simply turn the variable adjustment 14.7 mm outwards, this is easily adjustable by the distance marking. You are already at the optimum distance and can start taking pictures.
