This is a nice, lightweight, adjustable plastic red dot finder that now comes with two different bases: a two-hole base and a trapesoid-shaped/dovetail-type base that is compatible with most Skywatcher telescopes and with some Celestron telescopes (Celestron Newtonian and refractor telescopes) as well.

Can be used with both eyes open as it is built with a non-magnifying glass.

Window diameter: 24mm
Light control.
Plastic body with standard two hole base. Will fit most telescopes supplied with two threaded mounting studs. Distance between screws (measured centre to centre) should be about 14-28mm.
Works with CR2032 cell. (One included.)

Instructions

Installation

Install the "base" onto your telescope. Some telescopes would have pre-installed srews sticking out of the tube, if not, you'll have to drill and install your own screws. If you have to drill, we'd suggest to use a tiny bit of paint to cover the edges of the drilled hole so that it won't start rusting from there if you have a steel tube. If it's an aluminium tube, there is no need to paint.

How to use the red dot finder
First of all you have to remove the transparent plastic piece as that stops closing the electrical circuitry. In the future, if you need to replace the battery, it is there under a small black plastic cap. You might be able to remove that by just your finger, fingernail or with a flat screwdriver tip. Do it carefully, of curse, make sure no damage to the battery holder. 
Now switch on the RDF (red dot finder) by rotating the switch on the right hand side (when you stand behind the telescope) of the RDF. With this switch you can also regulate the level of brightness as it suits you, depending on how bright your celestial object is.
 
Aligning the red dot finder.
Once you installed the red dot finder you'll have to align it with the main telescope. 
Point the telescope at a distant object: chimney edge, antenna, street light etc.  If the object is far enough, this will give you a good precision, but you might have to repeat this at an object at infinity, i.e. the moon, a planet or a bright star, Vega, Arcturus, Altair etc. (please note, aligning to the Moon will not give you high precision due to its size, so use it only for rough alignment or just to point the telescope...)
 
Aligning the RDF to the mount can be done by turning the two alignment knobs: a vertical knob (for horizontal alignment) is at the front end on the right hand side of the RDF and a horizontal knob (for vertical alignment) is placed at the bottom at the rear end.
