Hi Lars,
Comments about "Vega mirror " are OK, but I really don't know if they used that kit or not (it is just my guess.. timing is right, that's for sure).
In Zagreb (I was born in that town and I spent there first 41 years of my life), I was a member of Astronomical society during my high school and uni days..Those were great times :-)We even became "famous"

this, post #10)
Below on the first picture is me on the Zagreb's Observatory terrace, '65 ~ '66 (?), second one was shot during my visit in Sept 2000 (you can see the glimpse of Zeiss 130/1954 mm refractor that was under the dome at the time).
