Exploitation

Mount­ed brack­et for a smart­phone on the eye­piece. With it, pho­tos through the eye­piece are sharp­er and with out­lined bor­ders, below you can see the dif­fer­ence. True, some­times the pho­to will have to be rotat­ed.

The smooth mag­ni­fi­ca­tion of the x25-75 device is clear, but at high mag­ni­fi­ca­tion the pic­ture shifts, the bound­aries of the field of view are already blurred. You need to con­stant­ly tight­en the focus. The opti­mal mag­ni­fi­ca­tion for com­fort­able work with the SV28 is x25 mag­ni­fi­ca­tion.

Exam­ples of device oper­a­tion day and night (at dif­fer­ent mag­ni­fi­ca­tions).
