Lentila Simpleta de la BauMax

-----------------------------------

Hello everybody.

Yesterday I was at BaoMax of Bucuresti, and I saw they are selling a "Lupa" de 90mm in sticla at 9 RON.

I took one of them (I needed to read electronic component details) and I saw the magnifier is not so bad: it is glass, it has not visible imperfections, and it seems to have a focal lenght pof 40-50 cm.

It is not a doublet, but I think it could be a good inexpensive item to build a big reflector for strict band observations (UHC?).
