TS-Optics Off-Axis Guider TSOAG9 - Length only 9 mm Reviews
1/7 Reviews
Wrote by Dominique B. on 22.05.2018
"The advantage of this OAG is to be very slim and to be compatible with optical corrector requiring a short distance to the CCD. Nevertheless it is difficult to adjust the position of the guiding camera, a stronger fixture with a precisely adjusting ring would be useful."
