I installed a permanent mount in my home observatory. It’s large and routinely carries telescopes like my 14.5-inch Cassegrain reflector. But I also like to shoot with smaller wide-field telescopes and camera lenses, especially from ultra-dark sites like Alturas in California.
For those times, I need a portable mount that’s more than just a tracker, one with an accurate polar-alignment scope and a reasonable price tag. After I saw Vixen’s GPD2 Equatorial Mount at the 2012 Northeast Astronomy Forum, I decided to buy one.
