Solarview 50 Instructions September 04

Care of your Solarview Telescope

It is imperative that your dedicated solar telescope, a precision instrument using a Fabry Perot 'air spaced' etalon is carried and handled with care. Always store and carry the Solarview Telescope in the case supplied. Avoid any knocks or blows. Do not drop the Solarview Telescope, such an impact could separate the optical contacts and may also cause irreparable damage to the etalon optical components

Optics

Clean only when necessary. Do not attempt to wipe dust off optics with a dry cloth. Use a photographic lens puffer to blow away dust specks. Then use a good quality optical lens cleaner with disposable lens tissue. Always replace the protective front and rear caps to the solarview telescope when not in use.

Procedures for Set up and use

Always take care when assembling Solarview telescope filter to main telescope body, prior to use do not over tighten filter.

A 1-¼" eyepiece and mirror star diagonal is required. The diagonal fits into the telescope end tube, which also accepts a CCD 1-¼" adapter. A safe and convenient way to align the sun with the telescope is to use a Tele - Vue Sol Searcher. This device screws into a groove provided on the telescope body. The body has a base with four ¼ - 20 holes for mounting purposes.

Do not look directly at the sun. Align telescope to the sun using an alignment aid such as the Tele-Vue Sol Searcher or use the telescope shadow projected on ground or white card.

With Solarview telescope aligned, focused and sun disc located in the centre of the field of view. The solar filter can now be tuned. The knurled rotary wheel on the side of filter allows the etalon a small degree of adjustable tilt. This tilt is used to fine-tune the filter bandpass and thus image resolution. Only adjust etalon fine tilt to optimise view while actually observing the solar disc. Effect to surface detail and image resolution will be immediately apparent.

Use same procedure for the double filter Solarview telescope, where the two etalons are used in series to enhance contrast. With the individual etalon fine tilt adjustment, remove all etalon back reflection images from the field of view when optimising image. Setting up the double filter system is routine, when familiar with the appropriate knurled rotary wheel positions.

The integral secondary filter at the eyepiece end is adjusted and preset to optimise contrast during final solar testing at the factory and does not require further adjustment.

Under no circumstances should the user remove the front filter unit from the Solarview telescope when is in use and aligned with the sun. The focused image will crack or cause irreparable damage to the secondary blocking filter.

* * WARNING * *

Under no circumstances should the user attempt to alter or remove any part of the Solarview telescope. Attempts to alter or tamper with the instrument will compromise its safety, may result in personal injury and will void guarantee.

If the Solarview telescope is to be used in conjunction with another finder or guide telescope, it is imperative that all optics of such other optical instruments are covered by a lens cap to prevent sunlight entering these instruments and to avoid accidental viewing.
