Telescope care: less cleaning, better storage
Cap the optics, let dew dry before sealing the telescope, remove loose dust with air first, and clean coated glass only when contamination affects use. A few dust specks are safer than unnecessary wiping.

Choose the options that fit your setup.
After every observing night
Bring the telescope into a dry, ventilated area with the optical surfaces protected from drips. Allow external condensation to clear before sealing caps and cases.
- Brush dirt from the tripod and mount
- Dry dew before closing a case
- Store with caps fitted once dry
Clean progressively
Start with no contact. Use a manual bulb blower for loose particles. If contamination remains, follow the exact method for your coating and optical design.
- Never use canned compressed air
- Use fresh optical tissue for each pass
- Apply almost no downward pressure
Know when to stop
Do not remove corrector plates or open sealed optical groups for routine cleaning. Fungus, oil films, internal haze, or mechanical damage belongs with the manufacturer or a qualified service shop.
- Internal dirt: service
- Dropped tube: inspect before adjusting
- Unknown coating: check the manual
