TELESCOPE BASICS
Telescope Maintenance
The main lens of the telescope is the most important part of the telescope, and all
Spectrum Optical Instruments telescopes have high transmission glass optics for
best performance. Each glass optic is fully coated, It is very important to protect
the coating and prevent any potential damages which can cause significant
decrease of performance. Here are a few maintenance tips you can perform to
ensure your telescope perform at its best for a long time.
• When the telescope is not in use, we recommend putting the dust cover back
onto the OTA to prevent any dust and/or moister build-up on the main optics.
• It is also recommended to cover the back of the OTA with the included plastic
plug to prevent foreign objects entering the OTA body and potentially causing
any damage to the inner coated surface of the OTA and more importantly, the
main optics.
• In case of dust/moisture build-up on the outside of the main optics, you can
remove it with a camel hair brush or pressurized air.
• When using a camel hair brush, make sure there is no foreign object
on the brush before using. Lightly move brush across the optic to
remove the dust/moisture;
• When using a can a pressurized air, spray the air onto the optics at an
angel so that the dust can be blown away from the optic.
• In case of moisture build-up occur on the inside of the OTA, remove the plastic
cover of the back of the OTA, and point the telescope downward to allow to
moisture to evaporate.
• In case of finger print/grease on the optics, it is necessary to remove it with the
correct cloth motion.
• Use any commercial optic cleaning solution with a optics cleaning
cloth/or white tissue with the least amount of debris;
• Apply the cleaning solution onto the cloth/tissue. DO NOT apply the
cleaning solution directly onto the optics;
• Apply the cloth/tissue to the optics with low pressure;
• Move the cloth/tissue from the center of the optics to the outer
portion. DO NOT RUB the optics!
• Repeat until optics is fully cleaned.
