Tilting device for the focuser of RC telescopes from GSO with an aperture of 10" or more
The new adjustment device for the focuser improves the image in the field: Every conventional RC telescope allows independent adjustment of the primary mirror cell, secondary mirror and focuser. With GSO, however, the primary mirror cell and focuser are connected to each other. When the primary mirror is adjusted, the focuser automatically moves with it. The result is minimal misalignment of the focuser. The well-corrected field of the RC is not used optimally.
When is the adjustment device useful and when is it not? We are talking about minimal amounts of tilt. When using DSLR cameras with half-frame chips or CCD cameras with chips up to approx. 23 mm in diameter, you will have no problems in the field. Observations can also be carried out without restriction.
However, if you use DSLR cameras with full-frame chips or high-resolution cameras with chips from approx. 23 mm in diameter, you will notice an increase in sharpness in the corners thanks to the individual correction of the focuser.
Mounting is easy:
- screw down the focuser
- screw the adjustment device up
- Secure the adjustment device with the small grub screw on the thread
- Screw the focuser onto the adjustment device
