Just wanted to let you know I love my 13.1” dob. I am very happy with the smoothness of the motions it is all of such high workmanship in the design. I finally got a site tube and aligned my secondary mirror to the focuser. Last week I had the scope out for 7 hours and the dew heater you installed worked perfectly. I am still waiting on my Paracorr 2 but it has shipped and will be here soon. I’ll let you know how things go when I get my coma corrector. Thanks again for building me such a nice scope. It’s perfect “for me”.
