Coronado H-Alpha Solar Telescopes

Coronado 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 optimized at H-Alpha. Most nighttime telescopes, when used at H-alpha, will not have the image contrast exhibited by a Maxscope 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 unnecessary scattering and spurious light transmission. All of the Coronado scopes, 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 filter 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 MaxScope series of which there are 4 apertures and varying band passes. Please read on below to learn about each one of these unique telescopes.

Model: MaxScope 40 Dedicated Solar Telescope

Description :

The MaxScope 40 has the same aperture as the P.S.T. but is distinguished by several key factors. The MaxScope 40 comes standard with a < 0.7angstrom bandpass which results in increased surface detail across the disk. A T-Max attached directly behind the etalon gives you the ability to adjust for Doppler shifted light. Bino-viewers and most imaging equipment will come to focus, sometimes with the use of a Barlow or OCS. These features plus enhanced surface detail make the MaxScope 40 a more versatile instrument with remarkable solar images. For more on the T-Max please go to accessories.

With the MaxScope 40 you will see all of the limb detail of the P.S.T. but with enhanced surface features. The MaxScope 40 comes standard with a BF5 blocking filter but a BF10 version is also available and recommended for use with imaging equipment and bino-viewers. The larger blocking filter allows you to extend the focal length without vignetting but does not enhance detail or lower the bandpass. You can also purchase a second SolarMax 40 / T-Max, along with a small adaptor plate, and attach these to the front in order to lower the bandpass to < 0.5 angstroms. This is called ‘double stacking’ and further enhances surface detail.

The MaxScope 40 comes standard with a clamshell mounting ring (some units have mounting rings) and hard travel case. Optional accessories include CEMAX series eyepieces and Sol Ranger sun finder.

Please be aware that prices in other countries may be higher to reflect the cost of shipping and import duties and taxes. Coronado does not take direct sales on the MaxScope40. However, for those of you with a <0.7 Angstrom Maxscope40 wishing to add an additional SolarMax 40 to further narrow the bandpass, we suggest you contact the factory directly

Specification :

Aperture	40mm
F/L	400mm
F/Ratio	F/10
Bandwidth	<0.7A - <0.5A
Thermal Stability	0.005 A/C
Blocking	Full blocking >105 from EUV to far IR

Model: MaxScope 60 Solar Telescope Package

Description :

For those looking for more aperture we proudly present the MaxScope 60 dedicated H-alpha telescope. Built to our exacting standards the MaxScope 60’s provides the user a telescope with the same lightweight portability of our MaxScope 40 but the extra aperture greatly increases the resolution of detail on the surface and on the limb. With over twice the surface area of the SolarMax 40 the difference is obvious.

The MaxScope 60 comes standard at <0.7 Angstroms with a BF10 and is available with an internal module to lower that to <0.5 Angstroms. A T-Max attached directly behind the etalon gives you the ability to adjust for Doppler shifted light. Bino-viewers and most imaging equipment will come to focus, sometimes with the use of a Barlow or OCS. The advantage of the extra aperture becomes clear each time you view. For more on the T-Max please go to accessories.

Included with every MaxScope 60 are the travel case, 25mm CEMAX eyepiece, and clamshell mounting system. Optional accessories include the Sol Ranger and additional CEMAX eyepieces.

“We had some really fine sunny weather here late last week, and I was able to put the MaxScope 60 (<0.5A) to the test. The ‘scope provides truly wonderful h-alpha views of the sun indeed. I spent a full day and a half just gazing through it visually! The Cemax eyepieces are terrific as well. I see what you mean about the Maxscope O.T.A. and Cemax eyepieces being worthwhile-they truly do provide excellent contrast, and therefore, great detail.” – Tom Stanley

Model: MaxScope 70 Solar Telescope Package

Description :

An astronomy teachers’s best friend, the MaxScope 70 has been designed as a sealed unit with no removable parts other than the eyepiece. Combine this with it ‘s 70mm aperture and you have a dedicated and portable H-Alpha telescope that is ideal for use by both the experienced observer and the most novice. As the MaxScope 70 is sealed no critical parts can be removed and set up is a breeze even for school children. Coronado recommends that all solar viewing be done under adult supervision to ensure safe and effective results.

The MaxScope 70 is in use at universities, high schools, middle schools, and their equivalents around the world. It is actually a version of our first dedicated H-Alpha telescope, Helios I, with technological improvements. All of the telescopes in this line (Helios I, NearStar, MaxScope 70) feature a unique design with an etalon smaller than the actual aperture and positioned towards the rear of the OTA. This enables us to price the 70mm telescope less than the MaxScope 60. This design creates a bandpass of <0.8 angstroms which is slightly higher than the standard for other MaxScope series telescopes.

The MaxScope 70 comes with a 25mm CEMAX eyepiece, clamshell mounting rings, Sol Ranger sun finder, and hard travel case. Optional accessories include the additional CEMAX eyepieces.

“The H-alpha views have been fantastic! This is going to be a great source of inspiration and understanding for the students for years to come. Thank You.” – Karl Von Ahnen.
