Our giveaway winner is Nicole from Journey to Excellence…Congrats & thanks for entering!
I’m so excited about our guest post today. Dr. Lisle shares ways your family can see the skies with household & inexpensive equipment. We love stargazing and I’m excited to try some of his ideas. Be sure to check out the upcoming transit of Venus (June 5-6) and how your kids can see it firsthand. The transit is rare and won’t be seen again until 2017!
The recent annular solar eclipse reminds us of just how many celestial wonders can be viewed without the aid of an expensive telescope. The sun (with appropriate filters for safety), the moon, the Milky Way, aurora, meteor showers, the constellations, and several star clusters are all visible with the unaided eye, if you know where and when to look.
These gems can be enjoyed by virtually everyone, without the need for pricy equipment. Stargazing is a wonderful and inexpensive hobby for homeschool families.
With a set of low-cost binoculars, an even larger world of celestial wonders opens up to stargazers. The moon is especially stunning during its first quarter phase, when it is half illuminated on the west side and high in the sky just after sunset. During this phase, the sunlight casts deep shadows along the craters and ridges near the moon’s terminator, revealing its spherical shape.
Binoculars allow homeschooling stargazers to see hundreds of amazing star clusters in the night sky. The Beehive cluster is a favorite during the spring. The Ptolemy and Butterfly clusters lie low in the South in the summer.
Binoculars reveal dozens of blue stars in the Pleiades in our winter sky. Even the Orion Nebula is easily visible with low power binoculars.
The upcoming transit of Venus this June is an event that no family should miss. Venus will cross directly in front of the sun – appearing as a tiny black disk against the bright solar sphere. This event will happen on the evening of June 5th for North America, and on the morning of June 6th for the Eastern Hemisphere.
Transits of Venus are very rare; the next one will not occur until the year 2117.
However, Venus will be very tiny without magnification. Binoculars will provide a much better view; this can be done safely in one of two ways.
First, solar filters which fit over the objective lenses of the binoculars will allow you to look through the binoculars directly. The solar filter must be placed over the (usually larger) lenses that are pointed at the sun.
Second, binoculars can be used without filters using the projection method. Leave the lens caps on one of the two objective lenses (we only need a single image). The binoculars are then pointed at the sun as usual, but instead of looking through them (which would be dangerous without filters) an image is projected on white paper several feet away.
Let your kids focus the binoculars to bring the light into a crisp image. Moving the paper farther away will make the image larger but fainter. Placing a cardboard cut-out around the binoculars will help increase the contrast and make the image easier to see.
