TAKAHASHI 76RD REDUCER 0.73x M60 The 115mm guide rings PLUS

The 115mm guide rings PLUS can be:

7A (tracking)

greatly simplifying access to the telescope for public observatories

letting through light only where optics are their sharpest (especially with refractors)

you need to calibrate your raw images with a flat frame

TAKAHASHI 76RD REDUCER 0.73x M60 The 115mm guide rings PLUSThe Takahashi 76RD Reducer is a 0. 73x focal reducer for FC 76DC DS fluorite doublet refractors. The optical design of this corrector is optimized for today's digital sensors, with better chromatic correction and field flatness. The 76RD Reducer has an image circle of 36mm, making it suitable for use with APS C sized sensors and smaller. The 0. 73x reduction factor transforms the FC 76DC DS into a 417mm f 5. 5 widefield astrograph. Spot diagram of
