Optical Kits

An incredible instrument with a glass mirror from the Baader planetarium in Germany. 2 objective lenses give you 16X and 30X magnification so you can use it effectively for observing the night sky and the moon's craters. Properly adjusted you can even see Jupiter's moons!

The main mirror is 70mm diameter, 450mm focal length and both mirrors are front-silvered. The hexagonal tube design strengthens the telescope body and the telescope is fixed on a Dobson mounting. Black and Gold printing make this a decorative as well as functional telescope.

This telescope kit parts are already die-cut for you which means construction is easier and quicker and much more precise.

This is the proper filter to allow you to make observations of sun-spots. 100,000X Neutral density filter reduces the brightness of the image so avoiding damage to your eyes.
(Warning: Do NOT look at the sun without using this!)

This telescope is based on an original attributed to Galileo which was given to Cosimo II of Medici. It corresponds in size and optical characteristics to the telescopes of that time. The telescope is beautifully printed in full colour with gold decoration and is complete with glass lenses and a wall/desk display holder. 78 cm long with a 12X magnification, this telescope lets you make the same observations Galileo would have made and imagine yourself to be back in 1609 when he perfected the telescope which had only been invented in Holland one year earlier.

A Galileo telescope which folds up smaller than a credit card to slip easily into your shirt pocket or wallet. In the record books as the world's smallest telescope.

A simple Galileo telescope 38cm long with a magnification of about 10X.

A small Galileo telescope that is simpler to assemble for younger constructors. Black and gold printing with crossed swords and skull and crossbones decoration. 6 times magnification.

This 5 section sailors telescope with 6x magnification collapses down to fit in a lidded storage box. It has a large (45mm) objective lens and gives an upright image. Pre-cut card with elegant gold and black printed decoration, the telescope measures 15cm when collapsed and 35cm extended.

This type of telescope uses a different set of lenses which gives a larger but inverted image. It is better than a Galileo telescope for astronomical use because of the larger, sharper image. This model is 45 cm long when extended and magnifies about 10X.

View the detail in salt crystals, feathers, textile fibres, etc. build a fully functioning microscope with 3 lens optical system giving 40 x magnification. Fully adjustable mirrors for both top and bottom illumination. Attractively printed in gold and black. Die-cut card for precise construction.

A precision pocket microscope no bigger than a cigar. View textile fibres, colour printing dots, butterfly wing scales, etc. Computer calculated 4 lens construction gives a colour corrected sharp image over the entire field of view. Stepless Zoom from 20x to 40x. Attractively printed in gold and black. Die-cut card for precise construction. Overall size 2x2x11.5cm.

An elegant old-style ''magic lantern'' model which actually works. Battery powered for child-safe operation, you can project the images onto a screen or blank wall. A 6V lamp with parabolic reflector, condensor lense and 2-lens objective give a reasonably bright image (although not upto the standard of a 100W slide projector). Create your own film strips by painting or drawing on transparent plastic or use 35mm film strip. Hours of fun kids and adults alike, Needs 4 AA batteries (not included-order code BT0012 @ £1.95 for 4).

Observe sunspots and eclipses safely. This device projects an image of the sun onto a screen via 3 lenses and a mirror and includes a 5 step adjustable iris to vary the brightness. Pre-cut card for precise construction. 20 x 20 x 25cm.

Make yor own kaleidoscope with this kit and fill the viewing chamber with your own choice of subject. Flower petals, beads or crumpled sweet papers will give different effects. Pre-cut card for easy construction.
