Imaging Star Apo refractors have been developed for dedicated astrophotographers. The objective and corrector are optimally matched for best results on the axis and in the field.
This Apo has a very high light intensity with f/5. The Apo offers a well-corrected and illuminated image field with a diameter of approx. 42 mm. Thanks to the moderate exposure times, noise can be kept to a minimum, which is particularly beneficial for owners of uncooled DSLR cameras. Of course, the Apo is also suitable for CCD cameras.
- The camera is connected via the M48x0.75 thread or the M68 thread. The distance from the M48 thread to the camera sensor is exactly 53 millimetres. The distance from the M68 thread to the camera sensor is 78 millimetres. This gives you enough space for individual adaptations and for all commercially available cameras.
- The newly designed 2.5" focuser holds even heavy cameras without tilting. It has been specially designed for photographic use. Adjustment is made via a rack and pinion mechanism without slipping. The knurled screw at the base locks the adjustment and thus guarantees that the focus position is held perfectly for hours. You can also fix the position of the focuser tube using a knurled screw on the upper side. The focuser holds the 3-element corrector and has an M68x1 ZEISS level external thread on the camera side. The reduction to M48x0.75 is also attached to this thread.
- Due to the relatively short distance between the corrector and the focus, the Apo is not suitable for use with normal 1.25" or 2" diagonal mirrors. Nevertheless, the Apo offers impressive visual performance thanks to its large corrected image field. Please use the special diagonal mirror from the "Recommended Accessories" section with item number 52336.
