How do I use the Starlight Instruments Desiccant Packs?
Simply place one or more packets inside any sealed container where you store your astronomy equipment. This includes telescope cases, eyepiece vaults, accessory boxes, and dry cabinets. The packets will begin absorbing ambient moisture immediately.
What kind of equipment should I protect with these desiccant packs?
These packs are ideal for protecting any moisture-sensitive gear. This includes:
-
Telescope Optics: SCTs, refractors, and reflectors stored in cases.
-
Eyepieces and Barlows: Especially multi-element designs susceptible to internal fungus.
-
Astrophotography Cameras: Protects sensors and electronics from corrosion.
-
Filters and Accessories: Prevents degradation of delicate coatings.
How do I know when to replace a Starlight Instruments desiccant pack?
The desiccant packs are self-indicating. The beads inside will be blue when they are fresh and actively absorbing moisture. When the beads turn pink, the pack is fully saturated and can no longer absorb moisture. At that point, you should discard it and replace it with a new one.
Can these desiccant packs prevent fungus growth on my telescope lenses?
Yes. Lens fungus thrives in dark, humid environments. By keeping the air inside your sealed telescope case dry, these desiccant packs create an environment that is hostile to fungus, significantly reducing the risk of it forming on your optical surfaces.
Are the Starlight Instruments desiccant packs reusable?
No, these packs are designed for single use. The manufacturer's description indicates that they "need replaced" when they turn pink. They are not designed to be recharged or baked dry. Once saturated, they should be discarded.
How many desiccant packs should I use in my large 11" SCT telescope case?
For a large case like one for an 11" SCT, it is recommended to start with two or three packs distributed inside the case. Check them periodically, especially after returning from a dewy night of observing. If they turn pink quickly, you may need to add more packs or ensure your case has a tight seal.
