Description

I have just started an ATM 10" newton project and have sold my 8" f/3.9 Quattro. So in order to do just a little photo observing, my TS102mm Fraunhofer acromatic refractor have been put into use.

It's not supposed to be used for imagin but more suited for lunar and planetare visual observations. However - it surprises me in it's performance, sharp, contrast and resolution is good.
