Coronado Safety Warnings
As with all of our solar viewing products the P.S.T.
built with safety as the top priority. This instrument was tested
and sealed at our facilities as a complete, safe, and working
unit. Do not attempt to disassemble the P.S.T.
. Doing so will
void your warranty and may compromise your safety.
Coronado is obsessed with safety and you should be too.
Details of our safety specifications can be found at
www.coronadofilters.com. Never use a solar filter unless the
manufacturer is able to provide such information. Before each
use make sure the P.S.T.
does not appear damaged in any
way – if you have any questions please contact
Coronado or your dealer.
Cleaning the P.S.T
™should be done with a fine
camel hair brush to remove any dirt from the
objective. High quality lens cleaner and a soft
cloth can also be used on the objective and the
body itself. Take care of the P.S.T.™ as you would
any high quality optical instrument and the views
will last a lifetime.
What You Will See With
The Coronado Personal Solar Telescope™.
The narrowband filter whithin the P.S.T.™ isolates
a specific bandwidth of light called Hydrogen
Alpha. This allows one to view the Sun’s
Chromosphere. The image of the Sun will be a
deep red across the entire disk. Be aware that it
can take time to ‘train’ one’s eye for H-Alpha
viewing. This instrument was designed for single
eyepiece visual use only. Coronado will not
guarantee the performance of aftermarket
products, including eyepieces, other than those
built by Coronado for the P.S.T.™.
Prominences – H-Alpha emissions projecting
beyond the limb of the Sun, consisting of complex
clouds or streamers of gas above or in the
Filaments – Prominences seen against the face
of the Sun, appearing as long narrow dark
streamers or diffuse complex dark areas in
H-Alpha light. Filaments often mark areas of
Active Region - A localized, transient volume of
the solar atmosphere in which plages, Sunspots,
and flares may be observed. Active regions are the
result of enhanced magnetic fields and appear
darker than the surrounding areas with a roughly
Plage – patchy H-Alpha brightening on the solar
disk, usually found in or near active regions, which
can last for several days. Plage is irregular in
shape and variable in brightness, marking areas of
nearly vertical emerging or reconnecting magnetic
Sunspots – Moderate to large spots usually
consist of a darker central region (umbra) and a
lighter halo consisting of many short fine fibrils
Flares - A sudden eruption of energy in the solar
atmosphere lasting minutes to hours, from which
radiation and particles are emitted.
Personal Solar Telescope
Manual ALTitude Azmimuth
Coronado has built a small, rugged, and portable
Alt-azimuth mount, M.A.L.T.A.™, to be used with
the P.S.T.™. The threads on the bottom of the
P.S.T.™ will accept any standard ¼ 20 pitch
photographic or astronomy mounting accessories.
To use the M.A.L.T.A.™ attach it to the P.S.T.™
using the two screws included with the M.A.L.T.A..
Then secure the mount head to the base using the
tension screw going thru the top down into the
base. The individual legs then thread into their
holes. By loosening the tension screw one can
adjust the azimuth or horizontal axis, retighten the
tension screw to freeze that axis. The silver
tension screw on the mount head will adjust the
altitude or vertical axis when loosened and hold
the P.S.T.™ firm when tightened down. See the
section on Sol Ranger™ for precise alignment.
Sol Ranger ™
The P.S.T.™ has been designed with an internal
Sol Ranger™ Sun spotting device. There is a
small pinhole on the front face of the P.S.T.™ body
and a small opaque window on the top, near the
eyepiece holder. When properly aligned on the
Sun the pinhole will let in light that will be projected
onto the opaque glass in the form of a small
harmless ball. It is NOT necessary to put your eye
up to the opaque glass. Best alignment will be
found when this ball of light is near center but it is
not always dead center. Adding a SM40/T-Max™
will obstruct the Sol Ranger™.
