An excellent budget solar telescope that seems to be worth considering.
The best solar telescopes in 2020 are typically small refractor instruments with modest apertures, usually 40mm to 60mm across in diameter. They feature special built-in interference filters to allow direct aiming at the sun while ensuring safety. It can be difficult to make a choice among the varied options on the market. So how do you distinguish the best solar telescopes from the not-so-great ones?
Utilize specially designed optics
A hydrogen alpha filter carries out efficient selective slicing and dicing of all the other colors from sunlight, leaving only a razor-thin slice of red light. This special filter essentially creates an artificial eclipse even when the sun is glaring brightly during your observation session. In fact, hydrogen alpha filters are even better than an actual eclipse in one aspect, as they render solar prominences visible aside from letting you see a variety of other solar phenomena that have remained hidden for ages from human vision. It’s the same with planets, imagine how much science has evolved that now we can look for Saturn rings through our home telescopes.
An H-alpha filter works by weeding out all except the narrow slice of H-alpha light. This is accomplished in a series of steps. First, over the telescope objective is a red glass pre-filter that rejects most of the shorter, bluer wavelengths at the beginning, allowing through only the red light to reach a Fabry-Perot etalon and blocking or dichroic filter located at the end of the telescope where the eyepiece is found. Working together, the filters mesh out unwanted light via destructive interference, which involves the removal of specific wavelengths through multiple reflections. Constructive interference is employed as well, which involves the amplification of the needed wavelength and transmitting it to the eye. The unwanted light is weeded out by the etalon in this manner, with the remaining necessary wavelength transmitted to the blocking filter that eliminates all the others as well, thereby sending just the desired H-alpha segment.
Some of the small, dedicated H-alpha scopes available are set up in a slightly different way, with the etalon, pre filter and blocking filters configured dissimilarly. However, one thing remains unchanged: all quality solar pro telescopes separate the H-alpha line using a combination or filtering and destructive/constructive interference. Smaller scopes also feature temperature-regulated heaters that are utilized for Doppler studies aside from pressure-tuning or a mechanical tilting mechanism to create variations in red light wavelength at diminutive to carry out Doppler studies.
There is greater elimination of off-band light with a narrower filter wavelength, which also results in a higher level of contrast. Those elements are essential for viewing chromosphere details. It is ideal to use filters with a passband of 0.7 to 0.5 angstrom to be able to view exceptional surface prominences and detail. A filter that transmits in the 0.9 to 2 angstrom range can still deliver decent views of prominences. However, disk details will be rather hard to distinguish because of lower contrast due to too much light, for instance.
Offer viewing of a rich variety of solar phenomena
The best value solar telescope allows you to view a spectacular array of solar phenomena that has remained hidden from the human eye for centuries until the introduction of this type of equipment. You’ll be stunned to behold spicules running all the way around the edge of the sun, looking exactly like red fur. Those are jets of hot gas extending between 2000 to 6000 miles high as viewed in profile. It would be spectacular to magnify a small group of those spicules to 100x or greater to see how long they can keep their shapes. Nature has ensured that around 300,000 active spicules stir the chromosphere at any given time.
One of H-alpha’s greatest highlights are the prominences, which are also much larger than spicules. Prominences can be seen along the solar circumference, with small ones frequently dwarfing our planet itself. Prominences are generally categorized as either active or quiescent. Looking like bushes or hedgerows, quiescent prominences are characterized by plenty of internal branching configuration, with some exhibiting structural alterations in just 10 minutes or so. Quiescent prominences or filaments tend to throw themselves slowly higher up in the corona before recollecting and settling back down into the chromosphere. Active prominences are flare-like structures that can be viewed as bright blobs or as sprays or nested loops at the limb. They’re breathtaking because of how they surge and change their shape in real time. Prominences are anchored in the photosphere to the surface of the sun.
Solar telescopes also allow you to see bundles of hot plasma called fibrils, which are confined in magnetic tubes and give the sun a swirly, dark and mottled appearance. Filigree resemble dark mottles and tendrils of glitter running between prominences. They are small, moderately bright points of light that define the chromospheric network. Bright, patch plages are more apparent when viewing the H-alpha sun for the first time. They mark the sites of active sunspot groups and regions. Sunspots have umbrae or dark cores that resemble what can be seen in white light, with the penumbrae branching out into remarkable spicule and fibril whirls. A premium quality solar telescope allows you to view an awesome amount of filament/fibril and plages detail in large groups of sunspots. Flares exhibit a characteristic sudden brightening within a sunspot group, looking like white-hot lava flows in multiple ribbons. Demonstrating raw star power, solar flares change in both intensity and area in real time and can last between a few minutes to hours.
A reliable heat stop and other components
The heat generated by the tightly-focused sunlight is an issue that cheap solar telescopes may not be equipped to handle effectively. A heat stop is an integral part of solar telescope design. This component is designed not only to survive the heat load but also to ensure that it remains cool enough not to roil any additional turbulence inside the dome of the telescope. Air motion due to convection is eliminated thanks to light paths operating in helium or a vacuum.
Telescopes with an aperture of over 1 meter do not allow this set up, as the pressure difference at the vacuum tube entrance window is too large. For this type of scope, there’s active cooling of the dome to reduce the temperature difference between the external and internal air of the instrument. A focuser, built-in solar viewfinder and bandpass fine adjustment controls enable easy use and viewing. The scope should also accommodate a variety of mounting options.
