From Wikipedia, the free encyclopedia. Star Clusters and how to Observe Them. These dim objects require a large objective mirror able to gather a large amount of light. The longer the optical path inside your telescope and the more unequal the air temperatures, the greater the problems the tube currents cause. Many designs have combined the advantages of a light truss tube and a collapsible design.

This will ensure the exposed parts of the tube stay closer to ambient temperature. The poles are held in place by quick-disconnecting clamps which allow the entire telescope to be easily broken down into its smaller components, facilitating their transport by vehicle or other means to an observing site.
Thank you! The main attribute of a Dobsonian's mount is that it resembles a "gun carriage" configuration with a "rocker box" consisting of a horizontal trunnion style altitude axis and a broadly supported azimuth axis, both making use of material such as plastic, Formica, and Teflon to achieve smooth operation.
