Against moisture in the telescope: Fits every 2 "eyepiece extract!
The telescope dryer is used to eliminate and prevent moisture in telescopes. It protects your system permanently while preventing the ingress of dirt. A permanently dry system provides no breeding ground for the development of lens fungus.
The situation: You spend one night outdoors and dew settles on all surfaces. All your equipment gets wet. In Newtonian systems, this humidity even reaches the inside of the telescope.
But not only by dew wet it gets wet. Temperature fluctuations alone create moisture inside telescopes. Even supposedly closed systems such as refractors, SCs or RCs are by no means protected against the formation of moisture inside!
The manufacturers give little help with drying. For venting and drying the tube in Newton telescopes, the dust protection is usually removed at the telescope opening. For RCs and SCs, the dust cover on the focuser is removed and the devices are set down with the correction plate for ventilation.
All this makes little sense, because:
- By opening the dust cover dirt particles of all kinds, eg dust, pollen and insects, can penetrate unhindered. That applies to all systems!
- By placing an RC or SC with the correction plate facing down, water stains may remain on the plate.
- It always remains a certain residual moisture in the device.
- Mechanical components such as the focuser can become sluggish due to dirt and rust.
All this usually results in the equipment having to be completely disassembled and cleaned. In part, the bearings of the focuser must be renewed. Especially with RCs and SCs a big and expensive effort.
Even worse is oxidation or infestation with lens fungus on optical surfaces. Many expensive devices fell victim to these problems.
The solution: Simply replace the dust cover of the focuser with the noctutec® telescope dryer.
Inside the dryer are silicate balls , which absorb the moisture. Protection prevents particles of desiccant from entering your telescope. If the silicate balls are saturated, they change their color from orange to green. You can open the dryer and dry the balls. This works in the oven at 50 ° C. You can also put the balls in a ceramic bowl on the heater. If the silicate is dry, the indicator assumes its original color. The dryer is now fit again.
The noctutec® telescope dryer should not be missing on any telescope!
