Hi Steve,

Those .965"/1.25" adapters worked fine in their day. Depending on what eyepieces Ken wants to use, they may adequately suit his needs now. If he is only going to be using shorter focal length, narrower FOV eyepieces then they will work fine. If he plans on using longer focal length, or wider FOV eyepieces like 24mm TV Panoptic, 20mm Pentax XW, 32mm TV Plossl etc those adapters might vignette somewhat. How bad, I am not sure. It may or may not be to a noticeable degree.

Cheers
John B
