Dobsonian Kits Rescue/Upgrade Kits for Dob's. Many moderately priced telescopes have very good optics and are a very good buy for the money. What they lack is mechanical integrity, smoothness and fine machining work that would make these scopes a lot more expensive: Astronomy Shoppe to the rescue!! We have several kits from focus upgrades to collimation, and these kits will work on the following telescopes : Meade LightBridge, Celestron StarHopper, Synta Skywatcher, Orion SkyQuest, Hardin DeepSky, DBA DSO, Zhummel Some of these instruments will benefit from minimum upgrades while others will benefit from a complete "KIT". Collimation Screws and Kits A Word about Collimation : Proper collimation only requires 3 screws. The so-called locking screws available on commercially made scopes should be placed next to the collimation screws if they are to be considered locking screws for the collimation knobs. Screws placed 60 degrees apart rather than 120 degrees apart will not act as a locking screw, but rather another collimation screw that will adversely affect proper collimation. These so called locking screws are in fact really support screws, and should be used as such and NOT relied upon as any sort of adjustment. Using these screws as an adjustment may in fact warp the primary mirror cell. Our "collimation kits" make it possible to use only 3 screws for proper and perfect collimation causing less strain to the primary mirror cell, our springs are stainless steel precision ground so they are perpendicular to the mirror for even support. The locking screws should only be used as a strain relief for the primary mirror cell.

Collimation Springs (Stainless Steel) 22lbs load each spring) These work great and carry a heavier load than what is currently available anywhere else.

Special Notes
Hummel Dobbs are a very good value for the money; we do not carry them, but do support these telescopes with all of our upgrade kits. Since they are a new company, some of the hardware sizes vary; therefore, if you are ordering a collimation kit for a Zhummel scope, email me to verify which size primary screws to send. tcostanzo@astronomy-shoppe.com Focus Upgrade Kits GSO Crayford Focuser "Upgrade adapter " and "Upgrade focuser kits " for Orion Telescopes superior to original and OEM upgrades.
