Coulter Optics 13” Primary and 3.1” secondary mirror set
My plans have changed so I am offering these two mirrors for someone to build a nice Dobsonian or if you buy the tube being offered by “multiweb” you can build an excellent Newtonian without breaking into your piggy bank…
Coulter Optics 13.1” F4.3 Primary Mirror (fl 1430mm) thickness about 30mm
Coulter Optics 3.1” Secondary Mirror (78mm m.a.)
These have never been used in a scope but are probably 15 years old.
Coatings are very good.
Selling for the princely xxxxxxx. + freight from Canberra..
I can email pix, but since I’m posting from my phone, can’t post the pix here…
