has developed a series of telescopes as a result of the often
asked question, “What is the best telescope to use with
a Coronado filter?” While almost all refractors and
most reflecting telescopes can be used with a Coronado filter,
no other telescope has been designed with all its optical
aberrations and coatings optimised at H-Alpha. Most nighttime
telscopes, when used at H-alpha, will not have the image contrast
exhibited by a SolarMax series telescope nor the image quality.
Most broadband coatings, used on such telescopes, will have
reduced effectiveness at this wavelength and telescopes (particularly
reflectors) not specifically designed for Solar viewing, will
exhibit unnecesary scattering and spurious light transmission.
All of the Coronado SolarMax telescopes, even the PST, have
been designed with this one wavelength of light in mind and
will increase contrast and give you a darker background for
viewing and imaging.
“Why buy a telescope that can only look at one object?”
The Sun in H-A is the most dynamic object you will ever see
while pointing a telescope skywards. Constantly changing and
never repeating itself the Sun through a Coronado SolarMax
telescope will hold your attention for a lifetime. Our telescopes
serve to enhance that view for you, your family, and friends.
The telescopes provide an easy and portable set up that is
always ready right out of the box.
The two different series of telescopes are the Personal Solar
Telescope, or PST, and the SolarMax series of which there
are 4 apertures and varying bandpasses. Please read on below
to learn about each one of these unique telescopes. Once you

angstrom H-A systems have long been cost prohibitive for the
amateur. Designs other than the Coronado are difficult to
use because of temperature and F-Ratio requirements. Not only
does the PST have a bandpass of <1.0 angstrom but it is
also thermally stable and requires no more time to operate
than putting in a eyepiece and adjusting the focus.
The PST represents the same technology and quality that goes
into a SolarMax series telescope but with a few unique design
characteristics that allow us to offer it for less than some
premium eyepieces. The PST will show you prominences, active
regions, filaments, as well as other surface details –
at <1.0 angstrom it will not reveal as much surface detail
as the SolarMax series telescope and filters but it certainly
“To be honest I was not expecting too much, bearing
in mind the cost and diminutive nature of the ‘scope,
I finally set up in the late afternoon. Alignment of the ‘scope
is a breeze using the inbuilt sun finder, as I looked through
the eyepiece I could see a red sun with a small sunspot but
no prominences or H-A detail and then decided to try the ‘tuner’,
as I rotated the ring the view changed, prominences popped
into view! With a little further “tweaking” filaments,
faculae, and “orange peel” surface came into view
in incredible detail! Absolutely brilliant…” –
