You focus by turning the focus knob -- on the side of the focuser. Practice during the day time on a distant object.

Im seeing my eye reflected back at me through the angled mirror.

You are NOT in focus. Put the eyepiece with the largest number written on it into the focuser. Go outside during the day time and practice focusing on a distant object-- turn the focuser knob slowly until the image comes to focus.

How do I adjust the Mars-eye elec. finder.

Contact Galileo telescopes here for help:

Assuming the batteries are OK, there should be adjustment screws on the finder for moving the red dot around.

Focus the telescope on a distant object, then without moving the scope adjust the dot on the same distant object.

You may be able to call Galileo telescopes and order the parts.

If not and if the eyepiece is a 1.25 inch (measure the hole in the focuser), then you can buy eyepieces and weights from several different retailers on-line:

The screw you can find at a well stocked hardware store.

Galileo FS-102CTC is not showing anything even after following instructions and adjusting the focus. I see my eyelashes and anything behind me.

This is a reflector style telescope with a MIRROR in the bottom of the scope tube, and a smaller tilted secondary mirror near the front of the scope tube.. Put the eyepiece with the largest number written on it into the focuser. During the day time take it outside and practice focusing on a distant object. DO NOT USE the 2x barlow if you have one.

The moon should be your first target at night. The eyepiece with the LARGEST number written on it gives the LOWEST magnification.

Be sure the lens CAP is not still on the front of the telescope. The FOCUSER end is the FRONT of the telescope. It should look like this:
