I found this useful to improve goto accuracy of my AZ-GTi.
Does exactly whats on the tin - no need to spend more. Brightness and focus can be adjusted to suit.

This eyepiece appears to be well constructed from good materials and does the job of centering the target perfectly. The reticle is clear and well defined with a variable brightness and an on/off switch. The sharpness of the reticle is adjustable, which is great. In fact, I found that it is possible to de-focus the reticle to such an extent that it becomes pretty much invisible at night, giving you a 'reticle free' 12.5mm eyepiece.
