Owners will beneift from getting to know the use and function of each of these two

adjustment knobs. The crayford style focuser will behave differently with the weight

of an eyepiece and diagonal / or camera than it does without added weight on the

telescope. Use caution when adding or removing heavy accessories in the drawtube.

Wing

Shift: If you are interested in exploring wing shift for experiments or variaiton in

view, the SolaREDi Odyssey offers +/- 0.5Å range of red / blue wing shift with the use

of the tuning knob.

Clockwise will tune the filter towards the red wing and

Counterclockwise turning will tune the telescope towards the blue wing.

Filtration and safety:

The optical solar filter stack is mounted at the rear, eyepiece end

of the SolaREDi Odyssey telescope. Alone, it provides off-band rejection density

greater than 6.0 from X-ray to beyond 2 microns. This means that it is safe to look

directly into the rear of a properly assembled SolaREDi Odyssey telescope without an

eyepiece. The SolaREDi Odyssey telescope requires no additional blocking filters or

special diagonals or eyepieces and unless it

is disassembled with tools, the telescope

cannot be rendered unsafe.

Should any

element of the filter age or degrade, that

degradation would cause a darkening of

the image and not an unsafe filtration.

- SLR, DSLR, CCD and webcam cameras

may be mounted in the 2" focuser using a

standard 2" to T-Thread camera adapter

and appropriate T-ring to camera adapter.

35mm film cameras or most DSLR's will

show full disk. Monochrome cameras are preferred over color models, for their

greater resolution and sensitivity at H-alpha.

We recommend the Moonglow Technologies Interference Eliminator with DSLR

cameras to eliminate 'Newtons Ring' interference patterns.

- Bino-Viewers can be used with the SolaREDi telescope. Barlows or negative lenses

are not necessary, as the focus travel of the telescope has already been increased by

the application of a TeleVue powermate.

- DayStar recommends 30-5 5 5mm Plossl eyepieces.

Note about digital imaging:

Hydrogen Alpha is a very narrow or monochromatic

wavelength of light. Many cameras which use a color CCD chip have sensors for blue,

green and red. The pixel sensors which are sensitive to blue and green have no data

in Halpha, so a color CCD chip will give 1/4 of the resolution that a monochrome chip

of the same size does. Also be aware that image processing algorithms often aver-

age pixels, which reduces image quality in addition to reduced resolution. While

color CCD imaging such as DSLR is convenient and accessible to the public, it includes

a number of unavoidable inherent limitations.

Fortunately, short exposures mean imagers can sort from

hundreds of frames over a span of time to select from superi-

or seeing cells which occur regularly. High speed imaging

and sorting from hundreds of frames greatly reduces the

need for stacking.

• The Best Digital imaging success in Hydrogen Alpha comes with a MONO-

CHROME SENSOR.

• Digital imagers should consider a way to tilt their chip through adapters or con-

figuration.

• Digital imagers should consider high speed imaging to image-sort for superior

seeing cells.

Care and cleaning:

While not in use, we recommend that users store the SolaREDi

alpha telescope with its end caps on, in the provided heavy duty re-sealable plastic

bag with dessicant dehydrating packets; in a climate controlled environment. The

SolaREDi telescope optical filter life expectancy is extended up to 2-3 times by cli-

mate controlled storage.

Do not touch the internal, red optical elements of the SolaREDi filter assembly.

While the exterior glass surface coatings are durable, they are easily scratched. A

few specks of dust will have no effect on the quality of the image, and may be gen-

tly blown off with a squeeze bulb. Do NOT use compressed air cans to blow dust

off any optical surfaces. Small amounts of residual 'film' will not affect visual per-

formance. Fingerprints, smudges and smears must be cleaned off. Preferred

cleaning method is to return the SolaREDi to the DayStar Filters laboratory for

proper factory cleaning. Do not unscrew, open or separate your SolaREDi filter

assembly. The optical elements are held under pressure by design and will

become damaged if opened. Opening the optical filter assembly will void your

warranty. The safest cleaning method is to moisten a very soft, lint-free tissue,

cloth or "Q-tip" with a pure acetone, methanol, or Isopropyl Alcohol (reagent

grade) and gently whisk away the stain. Do not apply solutions directly to the glass

surface. Stroke from the center of the aperture outward only. After each cleaning

stroke, use a fresh applicator. The fewer strokes, the better!

The tube and other parts are powder-coated for durability and can be polished

with any non-abrasive car wax. Red anodized surfaces can be cleaned with

Windex.
