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. The radius of the sun is 690 million meters—109 times the size of the Earth. 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.

Join Marc Silber at the B&H Event Space for a dynamic seminar that covers the basics from his new book Advancing Your Photography -- the definitive handbook that will take you through the entire process of becoming an accomplished photographer. From teaching you the basics to exploring the stages of the cycle of photography, Silber makes it clear and easy for you to master the art form.
When Galileo first championed Heliocentrism during the scientific revolution of the seventeenth century humanity strived to know exactly what the sun is
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
As preparations for the upcoming North American Solar Eclipse gain momentum, Meade Instruments now offers a broad line of white-light solar and eclipse-viewing optics called the EclipseView series. Consisting of a variety of devices, this new batch of products is designed to give users a wide range of options for observing our closest star. The entire EclipseView line features ISO-certified film filters that block 99.999% of the intense light from the sun,
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
