Optical Hardware (Ostara) 1.25" erect image diagonal.

Gives an upright image with left / right correct orientation.
Ideal for both terrestrial use and astronomy.

Compared to 45 degree erect image, mirror diagonals, the 90 degree one here 
uses a prism instead of a mirror. This means you get the benefit of being 
able to use your telescope more easily, and reduces neck strain compared 
to the 45 degree options.

Complete with dust covers and comes boxed.

Plastic but solid body that feels well built for the price

Not threaded to accept standard 1.25" filters
