Saturn is in opposition tonight: it  glides above the horizon around sunset and will be over 18-arc-seconds in diameter for a few weeks. At about magnitude 0.0, it will pair well with the full moon that accompanies it across the sky this evening.

Jupiter Opposition & Mercury Tangles with Uranus!

Jupiter will rise at sunset on May 9th. At magnitude -2.5 it will be an unmistakable sight: the brightest celestial object on the eastern horizon. It will also be closest to the Earth for the year.
 
A few days later, Mercury and Uranus draw nearer before sunrise. Mercury will be brilliant on the horizon, but northern observers will be challenged in finding Uranus in the gathering twilight.

Countdown: Total Solar Eclipse of August 21, 2017

Tele Vue President David Nagler exiting our building with all his eclipse observing gear in hand.

The media frenzy is growing as the first total solar eclipse to cross the North American continent in decades is closing in on us.

Our Tele Vue President David Nagler likes to travel light. So he built his eclipse observing kit around the Tele Vue TV-60 and Tele Vue Tele-Pod mount. In fact, he’s shown in the image here with not one but two complete telescope setups with a selection of eyepieces and solar viewers. Here’s a complete list of what he is carrying:

Saturn will be visible all night in the sky on the 15th as it rises when the sun sets (hence it is opposite the sun). Now is a good time to revisit an essay I wrote a while back about this visually appealing planet.

It’s Saturnday

I’ve found that first-time views of Saturn through a telescope typically elicit gasps of delight followed by inquisitive questioning.

Saturn’s startling beauty can open the door to wonders and knowledge about the universe that can inspire a love and appreciation of all the arts, sciences, and history.

Understanding something of the vastness and nature of the universe and our unique position as the only species possessing such knowledge suggests we commit to fostering the best in us: love, kindness, respect for learning and for all the amazing life-forms we’re so fortunate to share on this wonderful planet.

So let’s use Saturn as a means to enrich our future and help preserve our earthly paradise.

Spread the word to change Saturday to Saturnday through all media and contacts, in every social venue, to start dialogues that can open the minds and hearts of our earthling friends.  Caring for our precious planet and it’s lucky inhabitants, will make future generations proud of our time here.

Saturnday can change the world with your help !

Tonight Jupiter is closest to the earth and rises as the sun sets — the planet is in opposition. This will place it in the sky all night long. As the nights warm up into the spring, you’ll enjoy great views of this gas giant planet. Some of the best planetary images are made at opportunities like this.

2017 WSP with Prototype Image Intensifier!

Tim and Spencer Vent with Al Nagler.

What a pleasure to have long-time customers come over to our booth to say “hello” to “Uncle Al”. Tim and Spencer Vent came to WSP from Helena, AR. A special thanks to my friend Mal Speer who helps me set-up and demonstrate our products. Kermitis was parked on Tim Peters’ (DiscMount) van to greet visitors looking through our scopes.

Countdown: Annular Solar Eclipse Feb. 26, 2017

After the penumbral eclipse of the new moon on February 11th, we have an Annular Solar Eclipse just a half-lunar-cycle later. Unlike the lunar eclipse, this one will need proper filtering to observe naked eye or through scopes. The eclipse is annular because only the central part of the sun is obscured, leaving a thin ring (annulus) of light around the edge. This happens because the moon’s orbit brings it closer and further from the earth — so its angular size from earth can vary from 29.4-arc-minutes to 33.5-arc-minutes. The size of the sun hardly varies from 32-arc-minutes due to the small eccentricity of the earth’s orbit. Thus, the moon can appear to be bigger or smaller than the sun according to the circumstances. Continue reading “Countdown: Annular Solar Eclipse Feb. 26, 2017”

Penumbral Lunar Eclipse – Feb. 11, 2017

Some phase of this lunar eclipse is visible from most of the planet. All phases are visible in the region from the eastern parts of North and South America to Europe, Africa, and western Asia. The eclipse is “penumbral” because the moon misses the deepest part of the Earth’s shadows — the “umbra”. This also means it’s easy to miss the initial and later stages as the darkening is not as dramatic and it will lack the color-cast of an eclipse that includes passage through the umbra.
