Web29 mrt. 2024 · This works perfect for the RC8 flattening the field and reducing the focal ratio from f/8 to a faster f/6.4. The uncorrected focal length of the telescope is 1625mm. With this correction it is 1300mm. As seen in Image 2 and 6, I had to use all three of the supplied focuser extension rings to achieve focus with my CCD camera.

Web1 feb. 2024 · I think I would opt for the RC over the SCT for your purposes. Another contender is the 150mm F5~F6 newtonian. Even more inexpensive, simple, no corrector plates, no reducer needed. If you get F5~F6 you don't really need a coma corrector either. That still doubles your image scale too and F6 is fine.
