21 January

A spectacular night to observe the stars, with some auroral activity to the south, Jupiter and Mars and plenty of deep sky objects. A bright meteor is blazing the sky above our observatory.

 A fabulous night of observing with great conditions and some very special deep sky objects to look at.

Seeing

Seeing measures the steadiness of the atmosphere.

 

Amateur astronomers use the Antoniadi scale for seeing conditions.

Eugène Antoniadi was a Greek astronomer, who lived from 1870 to 1944, famous for creating the first map of Mercury and supporting through his observations the fact that the famous canals on Mars were an optical illusion. A crater on the Moon, one on Mars and a dorsum on Mercury were named in his honour.

His seeing scale is used even today by amateur astronomers:

The scale is a five-point system, with 1 being the best seeing conditions and 5 being the worst. The actual definitions are as follows:

  1. (I.) Perfect seeing, without a quiver.
  2. (II.) Slight quivering of the image with moments of calm lasting several seconds.
  3. (III.) Moderate seeing with larger air tremors that blur the image.
  4. (IV.) Poor seeing, constant troublesome undulations of the image.
  5. (V.) Very bad seeing, hardly stable enough to allow a rough sketch to be made.

Note that the scale is usually indicated by use of a Roman numeral or an ordinary number.

Transparency of the sky

Transparency measures the clarity of the atmosphere.

 

It is affected by dust, smoke, and humidity, which .end to reflect light pollution back towards the observer increasing the brigthtness of the background sky. In addition, it is affected by clouds. 

Darkness

Darkness measures the effect of light pollution on the objects we observe in the night sky. 

The Bortle Scale was invented by  John E. Bortle who published it in the February 2001 edition of Sky & Telescope magazine to help amateur astronomers evaluate the darkness of an observing site, and secondarily, to compare the darkness of observing sites.

What's with all the red light in the photos

We use only red light to preserve our night vision during a Star Safari. Our camera is also very sensitive to red light and combined with all the red lights that we use to illuminate the paths for safety, turns everthing into the fabulous red you see when we take long exposure photos. In reality these are fairy lights and red light torches.

Tonight was very exciting as we saw a glimpse of aurora to the South, so we took our camera and got some pretty colours onto the southern part of the sky. Stargazing from our place at Star Safari in Wairarapa is a treat because the sky is very dark, and with our telescopes, one can see really dim objects. We even looked at a quasar once – not in the summer sky though – so you’ll probably need to come back 🙂 for it.

Jupiter had all its moons on one side, which was spectacular as they lined up.

We looked at Tarantula Nebula, 47 Tucana, The Traffic Light, Black Arrow Cluster, Orion’s nebula, Pleiades, M41, and even M1 was visible.

All you have to do is count the number of stars on your street on a moonless night and report it online. We can show you how.

A Moon Garden for you

I grew up in an enchanted garden where the sky descended upon the world every night, bringing ripe heavenly summer fragrances, as the stars were watching from above. There was no border to separate the sky from the Earth. To simply to create that magic, is the only reason you need to have a Moon Garden.
