0.5 angstrom bandwidth double stack, ie a model of two front filters (standards).
This model includes two front Etalon filters. The image is darker and the surface details are more visible. The double stack especially improves the contrast. If necessary, the second Etalon filter can be removed, giving a telescope bandwidth of 0.7 ånström and a slightly brighter image.
Coronado's redesigned Solarmax III range offers a better 2-speed Crayford focus (rack & pinion), a modular design that allows the solar telescope to be converted to a star telescope as well. As a star telescope the aperture is 70 mm, as a solar telescope due to the filter the aperture is 60 mm. Suitable for beginners and more advanced enthusiasts of sun observation and photography.
The solar telescope is designed to operate at a hydrogen alpha wavelength of 652.8 nanometers. The image is dark red visually. Particularly spectacular images are created with a mono camera that captures various details of the sun’s surface such as sunspots, active areas, and the surface chromosphere. By adjusting the standard, or filter, in front of the telescope, you can fine-tune the appearance of details either in the surface chromosphere or the protuberances of the edges. Protuberances may be very short-lived, unlike sunspots, which can last for days or several weeks. The size and visible movement of protuberance due to its high speed is a memorable experience for someone who has a hard time finding anything similar in our solar system!
The surface of the sun can be intermittent without its major features, especially during the minimum time of solar activity. Unlike white light observations, hydrogen alpha almost always offers something to see. It is also good to get the eye used to detecting dark red light during the day. The
Always remember to attach the front filter and blocking filter when using the star telescope before looking at the sun again with the telescope.
