----------------------------------- horatius 24 Aug 2006 18:56 ----------------------------------- Nu m-am gandit sa-i fac vizita lui skw, din simplul motiv ca nu m-a invitat, iar oricum asta e o poveste care ne priveste pe noi doi shi nu pe tine. Doar daca nu vrei tu sa ma inviti tu la skw... Sky-Watcher nu face binocluri. Si ar trebui sa vii la Cluj sa vezi telescoape. Am spus ca, din punctul meu de vedere, un gaz intr-un binoclu e o contrarecomandare. E parerea mea. O fi diferita de a lui skw (ceea ce oricum deocamdata nu e clar), dar e parerea mea si e sustinuta de ideea ca un gaz va profita de orice orificiu petnru a se "strecura" afara. Binoculul Pentax e umplut cu azot, dar am impresia ca numai intre cele doua lentile ale obiectivului, ceea ce nu e un lucru neobisnuit (se practica si la unele refractoare apocromate scumpe).
