Are you having trouble with this?
Recently, the telescope's visibility has deteriorated. It looks like the optical axis is off somehow.
The movement of the equatorial mount is strange. It also makes noise and does not enter the field of view when the star is introduced.
There are places where the dome does not rotate. The movement of the slit is also not smooth.
In order to maintain the equipment for a long time, we recommend maintenance at least once every two years.
ーFrom lens cleaning to optical axis adjustmentー
Maintenance is essential for long-term use of equipment.
Dirt and mold adhering to lenses and mirrors deteriorates the surface coating, preventing the telescope from demonstrating its original performance.
The metal parts of the sliding part can also be adjusted and greased to prevent rust and provide a pleasant usability.
Equatorial mount maintenance
-An important frame that supports the telescope-
Perform proper maintenance to maintain introduction accuracy and tracking accuracy.
There are cases where the mechanical drive part does not work properly due to a lump of metal, adhesion of grease, or rust.
The adjustment of the polar axis is also an important point for operation.
Maintenance of the astronomical dome
ーThe symbol of the observatory that protects the telescopeー
Regular maintenance prevents accidents from occurring
Protect your telescope.
The dome has a surprisingly complex structure. Because it is heavy and hard to reach, it is also a place that is difficult to care for. In some cases, the slit suddenly stops working and the telescope is exposed to the rain.
by skilled technique
Confidence of " TOMITA" in technology based on 60 years of experience
The manufacturer does not matter. We maintain any telescope, equatorial mount, or astronomical dome. We do everything in-house instead of outsourcing.
Takahashi Manufacturing Technical Certificate
Our track record and technical capabilities were recognized, and we were the only company in Japan to receive a technical certificate from Takahashi Manufacturing.

Optical system Disassembly and cleaning
Disassemble the optics and clean the optical surfaces.
Wipe away any visible mold or dirt.
Cylinder wiping cleaning
Wipe off the dirt, mold, and dust attached to the inside of the cylinder.
has the effect of suppressing the growth of mold.
Optical axis adjustment Star image inspection
Adjust the optical axis of the optical system.
After adjustment, perform a visual inspection of the star image and an imaging inspection,
Check the optical axis status.
Focus adjustment Grease exchange
Cleans the degraded grease, greases up, and adjusts the rattling so that the focus can be adjusted smoothly.
We also perform maintenance on the attached finder and telescope.
The eyepiece is disassembled, and each optical surface is cleaned and centered for assembly.
Removes dirt and rust from the surface of the lens barrel to keep it looking beautiful.
TelescopeMaintenance BEFORE & AFTER
Equatorial mountmaintenance content
Check and adjust each driving part, such as contact of the worm gear with the worm wheel.
drive unit grease up
Remove the old grease from the parts where metal contacts and operate, and grease up.
Electrical system inspection/adjustment
Check the electrical system, such as the power supply lines to the right ascension and declination motors, for any abnormalities.
Confirmation of fixing screws and bolts
Inspect and adjust the tightness of each part and fixing screws and bolts.
Removes dirt and rust from the surface of the equatorial mount to keep it looking beautiful.
polar axis Inspection and adjustment
Check and adjust the polar axis for any misalignment.
We also accept motor drive modifications.
The system of the equatorial mount is old and automatic introduction and auto-guiding are not possible.
System computers that are old and cannot support the latest drafting software can be solved by replacing the motor drive of the equatorial mount. In addition, high-precision motors improve tracking accuracy and enable wireless communication.
Please leave the replacement of the equatorial mount to us.
astronomical domemaintenance content
Rotating motor inspection
We inspect and adjust the driving condition of the dome rotation motor and the degree of wheel wear.
Open/close motor inspection
Inspect and adjust the drive status of the slit open/close motor and the limit switch for any abnormalities.
Electrical system inspection
Check and adjust the electrical supply lines to each motor.
We inspect, clean, and grease each drive unit.
Confirmation of fixing screws and bolts
Check and adjust the tightness of fixing screws and bolts of each part.
You can also do this.
Stuck motor, replacement of worn wheels. Repair of corrosion and missing parts of the internal steel frame due to rain leaks. We also accept requests for repairs and renovation work necessary to extend the life of the dome, such as refilling areas where the sealing of the exterior sheet metal is broken.
