This is a nice, lightweight, adjustable plastic red dot finder with a plastic trapezoid shaped base that will fit most Skywatcher finderscope shoes. Some Celestron telescopes are being supplied with a similar shoe, so this will work with those as well if you need a replacement red dot finder.
Can be used with both eyes open as it is built with a non-magnifying glass.

Window diameter: 24mm
Light control.

Width of bottom of plastic trapezoid shaped base of the finderscope (that fits into the metal shoe) 30.5mm
Width of top of trapezoid plastic base of the finderscope: 22mm

Works with CR2032 cell battery. (One included.)



If you purchased this version, we assume that there is already a finderscope "shoe" on your telescope, alternatively a wide range of finderscope shoes are available from our webshop.

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 into 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 truning 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.
