Important Note:
For people with normal vision, this finder reaches infinity focus almost at the very end of the metal tube. The focus point is just about 1.25 turns inside the last thread. What this means is that you should be very careful when you first focus the finder as going past the focus point (last thread) could result in the dewshield (with the objective inside it) popping off in your hand or falling off. Once infinity focus has been reached and the lock ring secured firmly behind the objective/dewshield, everything will be fine. If you are nearsighted and observe without your glasses, you should have no problem reaching infinity focuser safely.
This is a very high quality yet economical 30mm GSO finder suitable for spotting scopes and small telescopes. It features a multi-coated achromatic objective and single eyepiece cross-hairs that allow for precise centering of faint objects. This finder provides an inverted, reversed image and is available in a white tube finish with black dewshield/diagonal/eyepiece only as shown in the accompanying photo. The finder comes with two plastic end caps.
The eyepiece body is made of high-quality molded ABS plastic. The rest of the finder is beautifully CNC-machined from aluminum and powder coated to a glossy finish. The inside of the tube is painted a flat black and the inside of the dewshield features v-grooves to minimize spurious reflections and maximize contrast.
To focus the finder:
(i) Turn the focus lock ring (on the tube right behind the dewshield) towards the eyepiece as far back as it will go.
(ii) Turn the objective dewshield in either direction until you reach focus while looking into the eyepiece.
(iii) Turn the focus lock ring towards the dewshield until it locks into place and can turn no farther. Focus will be locked in this position.
Please note: The eyepiece crosshairs are not focusable.
You can purchase an optional GSO quick-release dovetail bracket and a variety of dovetail bases for different applications (this item is also available with the bracket in a package at a small discount). Or you can mount the finder in your own 30mm finder bracket if the bracket has an inner diameter larger than 33mm.
