Barlow Tecnosky Apo 3X 31,8mm

Tecnosky presents a low-profile Apochromatic 3X barlow of excellent optical quality but at a price really accessible to everyone!
The choice of the barlow is a critical operation because if it is not of excellent quality it can worsen the telescope's performance; before proposing this product we performed numerous tests both on the optical bench and on the sky with direct comparisons with the famous and undisputed barlow of quality.
The 4-barlo Apo Tecnosky barlow came out head-up both as an incision and as a containment of reflections.
The 4 optical elements that make up the barlow are anti-reflective and multilayer and the inside of the aluminum body is threaded and blackened to minimize reflections.
The eyepieces are clamped with a brass band and therefore do not damage the barrel.
The thread for 31.8mm filters is also present.
