Spare part for Pressure-Tuner of LS50THa H-alpha solar telescopes from LUNT SOLAR SYSTEMS
A rubber O-ring is installed into the Pressure-Tuner of Lunt Solar Systems LS50THa solar telescopes to seal the air-pressure tuning system. Over time, the rubber of this O-ring can age and become porous, whereby the air-pressure can then no longer be maintained. When this happens, the old O-ring can be replaced by this spare part. The replacement is simple and can be done by the user. Installation instructions can be found here under the tab "Manuals" as a PDF for download.
After replacing the O-ring, the piston and cylinder of the Pressure-Tuner can be re-greased with grease available under part number 0558350.
Please note that this spare part can only be used on the Lunt Solar Systems LS50THa H-alpha solar telescopes. If the problem occurs on the larger THa or MT series telescopes, the larger O-rings with part numbers 0558330 or 0558340 must be used there.
- Inner-diameter: 31mm
- Outer-diameter: 39mm
- Cannot be used separately, only as a replacement part on the Pressure-Tuner of the LS50THa telescopes from Lunt Solar Systems.
- It does not matter what blocking filter is at the LS50THa
