Page 1 of 2 - New User Questions about 8 inch Dobsonian (Apertura AD8) - posted in Beginners Forum (No Astrophotography): Well after my first post and all the fantastic answers I decided to go with the AD8 from Apertura. After receiving and assembling it yesterday I managed to muddle my way through the collimation process. As it grew dark, I began to realize.. The Apertura AD8 tube assembly sits on the base with ease, and then the telescope can be manually moved up, down or to either side. To easily move the AD8 up and down but help it to stay in the desired position, the telescope tension can be adjusted to match the weight of accessories on the tube assembly.
