I was given an old Bushnell Spacemaster in perfect working condition. Not knowing what else to do with it, I bought a camera adapter and T-ring mount off ebay, to mount on an old Rebel XT that I found in one of my bins.

I'm not expecting much from an eyepiece projection mount, and indeed, the results aren't stellar. But it works... to a point. It cannot focus nearer than about 60-80 meters before running out of travel on the scope's focus knob. The scope alone can focus much nearer, maybe 5-10m.

Is there anything I can do to improve the near-side focus range on this setup?

  • Bringing the focus nearer is what macro-photography is about. Have you looked at macro adapter ? – Olivier Oct 26 '15 at 6:38

If you want to make your minimal focus point nearer, you could try technics derived from macro photography, such as an extension tube or close-up lens filters.

I don't know which one will make the correction you want but it probably exists.

  • Thanks! Adding a macro extension tube brought my minimum distance down by about 1/3. It's not perfect, but it's much more usable. – Autumn Oct 27 '15 at 17:54
