Interesantno.
Zapravo bi orbita oko Zemlje, trebala imati status općeg dobra svih Zemljana, i kao takva biti zaštićena od daljnjeg nekontroliranog onečišćavanja.
Prodajem OFGF AXIS guider velikog promjera koji ne vinjetira (ne zatamnjuje) rubove vašeg senzora.
Kamericu koju ćete koristiti za guiding, moguće je malo i pomicati pa tako i lakše pronaći adekvatnu zvijezdu za praćenje.
S obje strane ima iznutra navoj M 57.
Prizma se može spuštati ili dizati.
Dolazi s adapterom s M48 navojem, dosta tipičnim za razne adaptere za kamere.

Prodajem jer sam promijenio flattener pa mi više ne odgovara.
