Meet Me On The Equinox
We live in 195 countries, speak over 7100 languages and practice about 4200 different religions. Truly colorful!
Speaking of, did you know that the traditional Jewish holiday Hanukkah, a holiday lasts eight nights, has been known since ancient times as the “festival of light” for a reason?
The traditional Jewish calendar is luni-solar, which means that days and months are counted according to the phases of the Moon but corrected so that they do not stray from their seasons, more precisely from the seasonal positions of the Sun (two solstices and two equinoxes).
Hanukkah lasts eight days around the New Moon that is closest to the winter solstice (December 21 or 22).
The holiday begins two days after the third quarter before that New Moon.
When the New Moon passes, a long dark night follows again.
But as Hanukkah ends, the nights become brighter and soon, when we pass the winter solstice, the days become longer, and the midday Sun moves higher in the sky.
This is the meaning of Hanukkah and the traditional custom of keeping the light of a candle or lamp on during those days. Hence the name – festival of light!
Dear Santa, telescopes are the coolest!
Perhaps this mini instruction is late because the date is already high and for many Santa Claus has already bought a telescope. Maybe.
However, let’s make some suggestions, just in case.
- High magnification says nothing about the quality of the telescope.
- With telescopes, it is important how much information (light, photons) reaches the eyepiece. The larger the mirror (or the lens of this type of telescope), the more information you get in the eyepiece.
- It is much better to have a sharp image, which is achieved with a lower magnification, than a blurry one with a high magnification.
- Check how the telescope is made, how stable it is, how well each of its elements is made.
- The eyepiece must be easily but firmly placed in its seat, the tripod must easily bear the weight of the telescope.
We will briefly describe what can be seen with a smaller and larger telescope:
Remember: The Sun can only be viewed through special filters or through a solar telescope!
- Binoculars: Larger planets, variable stars, bright comets. About 9 – 10 magnitude.
- Telescope with a diameter of 5 – 6 cm: Details on the Sun, Moon, contours of the planets, solar and lunar eclipses. About 10 magnitude.
- Diameter 8 – 10 cm: Brighter celestial objects, details on planets, moons of Jupiter, about 11 – 12 magnitude.
- Diameter 12 – 15 cm: Thousands of celestial objects, clusters of stars, galaxies. The surface lines of the planets are clearly visible, they collect enough light for photography.
- Diameter greater than 20 cm: Distant celestial objects are no longer just faint spots, but unique objects with increasingly visible details.
