Teleskop Vega

Filtersko kolo UBVRI

Filtre nastavimo z ukazom:

tx set filter=V

postavi optični filter "V" v okno. Za pravilno delovanje mora na računalniku mira teci program filter_server.py. Glej navodila za zagon teleskopa. V kolesu so Johnson-Cosinus fotometrični filtri:

OznakaVal.dolž.ŠirinaOpomba
U41070ultraviolični
B45070modri
V550100zeleni, vidni
R600130rdeči
I720150infra
W-500belo steklo

Optično so filtri tako narejeni da se nastavitev gorišča na teleskopu pri menjavi filtra naj nebi spremenila.
