Had a phonecall from a poten- tial customer who asked about a telescope he’d seen advertised on the internet as “Parabolic mirror Newtorian refractor. Ideal telescope for youngsters and beginners...... It offers clear images and an excellent quality / price ratio thanks to the essen- tiality of the optical, making it a suitable instrument for all types of astronomical observation. “ If every other telescopes could combine “essentiality of the optical” with a “mirror Newto- nian refractor” life would be so much easier, ...... wouldn’t it? * * *

The camera cannot actually see an Earth-like planet but can detect the dimming of its parent ’s light if the planet orbits between the star and the Earth.
