Description

Recently I bought a 2.67x APM coma correcting barlow lens.
This is a special for newton telescopes (up to f4) developed coma corrective barlow with ED lens. It can also be used with SC and Refractor telescopes.
The coma free area is up to APSC
This is the first light of the barlow lens. Due to cloudy weather I could try it only on the Moon.
Unfortunately the seeing was pretty bad.
My first impression is good so far :-)
