This handy new accessory, the Ronchi eyepiece from Gerd Neumann jr. (the manufacturer of the famous high quality Astronomik filters) will help you to confirm the optical quality of nearly any telescope that you'll come across in the future!
The Ronchi test is easier to perform than a star test as it doesn't require the same level of steadiness and viewing conditions of air as the star test.

The difference from other  makes is that the gratings on the Gerd Neumann Ronchi eyepiece is created by a vacuum metalised chrome layer on glass, therefore it is of much higher quality than film or laser printout gratings.

Specifications
Body: black anodised aluminium
Grating: 10 lines per mm
