Telescope Upgrades

Match the Upgrade to the Problem

• Image shifts or slips when focusing: A dual-speed focuser or a motor focus kit.
• Collimation needs tools: Bob's Knobs thumbscrews replace factory screws on SCTs and Newtonian primaries.
• Dew on the corrector or lens: A dew shield first, then a heater and controller.
• Boiling views after setup: A cooling fan helps Newtonian and Dobsonian mirrors reach outside temperature faster.
• Tube moves on its own: A Dobsonian brake or better altitude bearing tension.

Telescope Upgrades: Frequently Asked Questions

What is the most useful first upgrade?

It depends on the telescope. For SCTs, a dew shield and collimation knobs. For Dobsonians, a cooling fan and a good finder. For refractors used for imaging, a stronger focuser.

Will an upgrade void my warranty?

Bolt-on upgrades generally do not. Modifying optics or drilling the tube can. Ask us if you are unsure.
