Solar filter on Heritage 130p

Recommended Posts

Hi everyone,

As I am about to buy the 200p for my planetary and DSO viewing I was thinking of making my heritage 130p into a solar viewer but I don't know how safe it would be. This is mainly because of its exposed secondary. If I bought solar filter I would but it at the bottom of the scope, where it becomes solid as I have a round easter egg box lid that slots in perfectly but I'm worried about the secondary being exposed. Will the angle of it stop any unfiltered rays or should I make a shroud?

Thanks in advance,

Sion

The solar filter must be placed above the secondary and the open truss covered with a shroud. If you put the filter below the secondary there will be reflected sunlight from the filter going back to the secondary and into your eye.

Ok, thanks for the reply :). Any suggestions on what to make a shroud from?

Thanks again,
