TWIN FALLS, Idaho (KMVT/KSVT) —There are a few times in your life that people will encourage you to look at the sun. Well, starting Wednesday, May 29 that’s exactly what the Centennial Observatory will be doing as they break out the solar viewing telescopes. Now, you may be wondering what makes a solar telescope different from a standard telescope. The College of Southern Idaho has three types of solar telescopes that are available to them. The first type is a model called a “folded refractor” it has the unique feature of being the only telescope that you don’t look directly through.

“Your normal telescope you’d think of having as having a lens in the front, a lens on the back. This one has both of those, but in between it has mirrors that allow it to kind of fold up,” Observatory Coordinator at the Centennial Observatory Chris Anderson said. Without the traditional lens to look through the image is instead projected onto a piece of paper set within the telescope and this makes it better for larger groups. “There was a company back East that made these specifically for classrooms and they’ve continued to make them ever since,” Mr. Anderson explained.

The second model they have available to them is a traditional telescope, but adjusted with a specialized filter that is added onto it making it possible to view both the sun and the stars when needed. “We have a white light solar filter in it right now and a white light filter just dims the sun way, way down and lets you see what’s going on, on the surface,” Mr. Anderson explained. As of right now, the sun has been fairly active, but the peak of our current solar cycle is expected to hit within the next year or two and a half years.

The third model that they have at their disposal is also the most advanced, it’s called a “Hydrogen Alpha Telescope”, and it blocks out all color except for a specific shade of red that is emitted from the sun called the “Chromosphere”.

“If you’re used to thinking about what you see during a total solar eclipse. So, this little red thing’s poking out from around the edge of the sun. That’s the chromosphere,” Mr. Anderson explained. When looking through the telescope you see a black dot with a grainy, almost oatmeal-like texture that is the sun, and it’s all thanks to the specialized filters that are built into the telescope itself, but that’s not the only cool thing about it. “It is a computer-controlled telescope. It does track the sun automatically, so I don’t have to work about it keeping up,” Mr. Anderson said.

Now, while the sun is extremely active you may want to get in on sun spots, Chris Anderson implores everyone to come down and visit rather than trying to see the sun on your own.

“If you don’t have the proper equipment, don’t try to look to look at the sun with a telescope. That’s an incredibly dangerous thing to do. What a lot of people don’t realize is that it’s not just about whether you’re feeling discomfort. There are ways to filter the sun down in a way that you don’t feel any discomfort, but you’re still doing damage,” Mr. Anderson said.

Even with powerful welder’s glass unless it is a number 14 glass or dark you can still permanently damage your eyes. It is simply safer to not take the risk, rather visit Centennial Observatory on one of the many solar viewing days that will be open to the public. The sun viewing days are every Wednesday following Memorial Day until Labor Day from 1:30 to 3:30 P.M.
