The sun is a lot larger than people think. When we see it in the sky, it looks small (as big as our Moon looks, in fact). However, it only looks this small because of how far away it is.

To put that into perspective, if the sun were a balloon blown up to about one foot across, the earth would be the size of a peppercorn. It makes one think, “Well what about the largest planet in our Solar System?” At that scale, Jupiter would be about the size of an unshelled walnut.

The Sun, our source of light and warmth, is a notoriously poor photographic target, due to its extreme brightness and constant emissions of damaging ultraviolet and infrared radiation. However, with the right equipment, the sun can be a challenging and rewarding photographic subject. The sun, like the moon, is above the horizon and in our skies half of the time. However, unlike the moon, when the sun is above the horizon, it is always visible (unless it is cloudy). The moon progresses through different phases as it orbits our planet, from new

If you have an interest in astronomy, chances are that you’ve heard of the upcoming North America Eclipse, in August 2017. And if you have a conventional telescope, you know the problem is these telescopes are all made for nighttime use so, to use them for solar and solar eclipse viewing, you need special filters to protect your instrument and (more importantly) your eyes. Luckily, we here at B&H have you covered, with filters to adapt your telescope for viewing the sun in general, and the solar eclipse, in particular. First Things First

A great deal of mystery and misconception surround the topic of observing the sun and solar eclipses, and while you should absolutely not look directly at the sun without proper protection, we here at B&H have got you covered on how to enjoy viewing the sun and, later this year, the solar eclipse. Read on to see what’s available for you, if you’re interested in investing in a dedicated solar telescope. White Light or Narrow Band? Right out of the gate, you need to decide: White light or Narrow-band (Targeted) viewing? For specifics about
