TS-Optics REFRACTOR Corrector 0.8x for refractors from 102 mm aperture - ADJUSTABLE

TS Photoline 0.8x focal length reducer and corrector for refractors from 102mm aperture

The corrector increases the speed of your refracting telescope and reduces the focal length for a larger field. The exposure time is reduced to 64%. In addition, the corrector corrects the field and ensures pinpoint stars to the edge of the frame.

Set the corrector individually for your camera and your refractor. No more adapter battles!

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 in fractions of a millimeter. As soon as you have reached the desired distance, fix it with the clamping screw. With the camera attached, you can use test shots to determine the optimal distance without additional adapters or adjustment rings. The camera does not rotate during fine adjustment.

The following adjustments are recommended from the innermost position of the adjustment to the sensor:

♦ 102mm aperture / f/7 - 69.87mm focal ratio

♦ Aperture 107 mm / focal ratio f/6.5 - 69.0 mm

♦ 130mm aperture / f/7 - 66.17mm focal ratio

♦ 140mm aperture / f/6.5 - 65.8mm focal ratio

♦ 150mm aperture / f/8 - 63.34mm focal ratio

♦ 155mm aperture / f/8 - 62.57mm focal ratio

Connection to the telescope:

This Photoline Reducer has an external thread M63x1 on the telescope side. Many focusers already have this thread as standard. Adapters for other threads, such as M68x1, are of course available.

Application example: how do I set the distance:

Setting the correct distance is very easy, as we show in the following example:

♦ Telescope: refractor with 130mm f/7 aperture, that is, 910mm focal length.

♦ Camera: Reflex camera with a distance of 55 mm from the M48 thread to the sensor.

According to the table, the working distance is 66.17 mm. Simply subtract the 55mm (distance from wire to sensor) from this measurement. 11.17mm left.

Simply turn the variable adjustment 11.17mm out, this is easily adjustable thanks to the distance marking. They are now at the optimal distance and can start taking pictures.
