E chiar bun... Am acest tip de Barlow şi sunt mulţumit de el... Nu introduce aberaţii sesizabile de nici un fel...

[Alex Alexandru]

Multumesc pentru apreciere... eu pot spune ca nu sunt expert si nu sesizez cu usurinta aberatii cromatice, insa ce pot spune cu certitudine este ca este si mai luminos (nu intuneca imaginea la fel de tare) si evident mareste mai bine decat 2 X -ul de la Celestron (cel cu care vine kitul Celestron AstroMaster II).
