Coronado SolarMax 40 Solar Telescope

The award winning Coronado SolarMax 40 Ha solar telescope comes standard with a < 0.7 angstrom 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. Enjoy prominences, flares and surface detail visually as well as having the versatility to image the sun this is a superb solar astronomy package.

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 SolarMax 40 telescope a more versatile instrument with remarkable solar images.


BBC Sky at Night Magazine Group Test Winner - "This scope delivered the best overall low-power view of the Sun in this test"

With the SolarMax 40 telescope you will see all of the limb detail of the PST but with enhanced surface features. The SolarMax 40 telescope now comes standard with a BF10 blocking filter 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 filter & T-Max tuner 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 even further.

The SolarMax 40 telescope comes standard with a clamshell mounting ring and hard travel case. Included with this superb Solar telescope package is the Sol Ranger sun finder and a dedicated Coronado Cemax eyepiece.
