If you're buying a dome to go in your backyard and need the ultimate in stability, call the contractors and fork lift operators 'cuz we need to be pouring or drilling concrete!
When mounted in the equatorial mode, there is no field rotation in either the main telescope or in any auxiliary, piggybacked instruments. Ideal for installations planned for astrophotography and imaging applications.
All Permanent Equatorial Piers are custom-manufactured to match the latitude of the specified observing site to an accuracy of 1/2 degree or better. Fine tuning and leveling is then typically accomplished using the pier mounting bolts. Specify latitude at time of order. Standard pier height is approximately 42", custom height available on request. Additional charges apply for increased height.
Specify the latitude of your permanent observing site to within .5 degrees when ordering. OPT will call you with a expected timeframe, since these are custom-made. If you have not purchased your telescope yet, remember that it is more economical to buy the pier as part of the telescope package than separately.
