Darkening or degradation of the image:
Filters older than 10 years do frequently require service. The most common service requirement is the replacement of 2 optical components which age and darken over time. Those are the 'blocker and trimmer' elements. As these two elements age, they darken and lose contrast concentrically from the outside to the inside. A user will notice the view slowly developing poor contrast towards the outside of the aperture. On a visual inspection of the filter, the red side of the filter will show a dark or mottled, donught shaped ring forming from the outside in. The gold side often evidences as speckles or dots in the same ring pattern from the outside in.
Please DO NOT open your filter yourself and attempt to perform any repairs on your own. There are no user-servicable parts inside; and simply twisting the optical elements in your filter stack can cause irreperable damage to the system.
• Repair service for these two elements is $750.00
Replaced blocker & trimmers are warranted for another 10 years.
This is normal age-related element failure which occurs slowly sometime after 10 years. Climate conditions in which the filter is kept will either accelerate or decelerate the speed in which this darkening occurs. A warm and moist environment will speed this deterioration process. Users should try to store the filter in a dry, room temperture environment. Some users in tropical zones use desicant packets in their storage to protect the filter. There is no precise forcast to how long a filter will function. We have found filters kept in constant operation to still be functioning perfectly after 25 years, while others fail in 12.
110 - 240vac heaters which have been plugged into 12vdc without the proper sine-wave converter will be permanently damaged and will no longer heat.
• Upgrade for heater assemblies to a new, functional Quantum assembly is $750.00 plus shipping
Replaced heaters are warrented for another 10 years.
Clean and Check:
DayStar offers a standard clean-and-check service for filters which may have fallen into disrepair, become dirty or whose settings have been incorrectly set.
• Clean and Check service is $45.00 plus shipping
Turnaround for this service is currently 3 weeks.
DayStar offers an etalon upgrade service, whereas we remove the etalon crystal of your DayStar Filter and replace it with a narrower bandpass or PE / University quality etalon. Those prices are available upon quotation and are subject to availability of desired etalon crystal. For information and pricing on etalon upgrades, please contact Pete Reynolds at firstname.lastname@example.org
User-Damaged / Missing Etalon Restoration:
Unfortuately, users may chose to void their warranty, opening the DayStar out of curiosity. While we advise to NEVER OPEN A DAYSTAR FILTER for risk of damage to the etalon crystal, we occasionally must restore filters damaged by curious users. Pricing and terms for USER-DAMAGED / MISSING ETALON RESTORATION is available here.
Turnaround for this service is variable to the type of damage encountered.
