When using our solar filters as directed, it is perfectly safe the observe the Sun. The included blocking filter reflects most of the incoming light and heat harmlessly back out of the front of the telescope.
Do not disassemble the filter, the blocking element is separated from the etalon and the complete assembly must be used together for safe viewing.
Do not power the filter from a computer or cell phone charger as the Quark requires a high current power supply (more than 1.5 Amps) for operation.
Do not leave the telescope unattended unless remote monitoring systems are in place.
Beware of cheap telescopes (often made in China) that have plastic internal baffles, as off center pointing could cast light onto the plastic and melt them. Quality telescopes will have metal baffles that can tolerate heat.
Cautions & Warnings:
There are no user serviceable parts inside the Quark. Do not diassemble the unit. Certain components are under pressure and disassembly can cause permanent damage. All elements are required for proper operation and removal of any internal component will cause a malfunction that could result in unfiltered light which can cause blindness or damage to equipment.
- Solar Observing with a telescope is sensitive to certain risks. Caution and care of the telescope and filter is advised in assembly, use and dismantling at all times.
- Telescope owners must use caution when affixing the filter to the telescope never to point any telescope at the sun without the solar filter safely installed first.
- While observing, owners must take care and caution that all parts of the filter and telescope assembly are properly affixed and that no pieces have been opened, tampered with or removed.
- Owners must also use caution when the telescope is being assembled and dismantled to assure the telescope is never pointing at the sun without the solar filter properly installed.
- Responsible owners will be prudent to inform guest or novice observers of the special nature of the telescope configuration so not to imply that telescopic observing of the sun is safe without proper filtration.
A few very important points that owners and operators must understand:
- DayStar filters are rear-mounted and can be applied to a choice of telescopes if applied properly. If application is incorrect, the filter will not perform as specified.
- DayStar Filters are interference filters. If light reaches a DayStar Filter at an angle, it will cause wavelength wingshift. For our application on a telescope, DayStar owners need F/15 to F/30 light, so we need to alter your telescope’s F/ratio in order to reach F/15 to F/30 where your DayStar will operate correctly. Best performance is at F/27-F/32.
- DayStar filters are temperature sensitive. Changing the temperature will change the wavelength (CWL) that the filter will transmit. Users need to be aware of temperature tuning issues.
