Upgrades and Tweaks

These are some of the most popular upgrades and tweaks that astronomers have discovered can improve their Dobsonian telescopes' performance, convenience, and handling. The parts on this page can be installed on many popular Dobsonian Telescopes currently available on the market today including Apertura(tm), Astro-Tech, GSO, and Zhumell, as well as some brands no longer available including DBA Astronomy and Hardin Optical. Some parts MAY also work with other brands such as Meade, Celestron, Skywatcher, etc. but you should determine whether they will fit your scope before ordering. Contact us if you have any questions.

 

The upgrades and tweaks available on this page are intended to be ordered separately and installed by the customer on their own Dobsonian telescope. All of these items are also included as part of the optional Tweaker's Dream(tm) Package for Apertura(tm) Dobsonians (with factory installation included as part of that package). If you wish to order the full Tweaker's Dream(tm) Package with your Apertura(tm) Dobsonian, please check that option on the Telescope page when placing your order and do NOT order these parts separately.

 

Prices for Upgrades and Tweaks INCLUDE postage in the Continental U.S.!
