1.25″ Focusers

These 1.25″ focusers are not new at all. But it looks hot sale these days. So I just thought I wanted to share with you.  7315(non-rotating) and 4317(rotating) turn very easy solution for precise focusing when used with 7316(1.25″ nosepiece).

7315 is connected via T-thread without camera’s nosepiece. So it is a kind camera’s nosepiece becomes focuser. It should be very useful for fine-tuning if the scope’s focuser is not enough precise.

Although it is a rotating focuser, it shouldn’t be the issue when used with eyepieces. This is easy and economical solution for high-power viewing. Since it is set after the diagonal, it’s smooth and precise enough for fine-tuning. Also both of focusers are very useful for the scopes which have image shift during turning the original focus knobs.
