How bright is that star? Magnitude explained

posted in: Astronomy | 0

Understanding Magnitude How bright is that star? is actually a very good question and one I am asked many times on our courses and when we have visitors outside here at Astrofarm gazing at our night sky. To answer, the first thing we need to establish is “compared to what?” This may be another star or a planet.  Then we need to look at the scale on which star brightness is measured. This scale is called the “Magnitude Scale” and is … Read More

A beginner’s guide to magnification with telescopes

posted in: Astronomy | 0

What magnification is that? When showing people objects through a telescope for the first time, be it the Moon, a planet or another celestial body, one of the most asked questions is “What magnification is that”. It is important that we as astronomers know not only the answer, but also know how to describe the value of the answer. Like all of my blogs I am going to keep this simple and not try and baffle anyone with long explanations and … Read More

My astro journey in 2016 A new adventure My astro Journey 2016 should perhaps be called my astro-photography journey as I seem to have embraced this side of astronomy since moving to France. I am very fortunate, I know, to enjoy such wonderful dark skies and a micro-climate giving as many sunshine hours as the South of France. Having spent the previous 8 years in the North West of England, I was more used to grabbing a couple of hours … Read More

Solstice Special

posted in: Astronomy | 0

Solstice What is a solstice? The word solstice comes from the Latin word for sun (sol) and the word meaning to ‘stand still’ because it appears that the Sun stops and changes direction. Since we can remember we have looked at the Sun, Moon and stars and watched these celestial bodies move across the sky. We have observed, documented and calculated these movements. Some have even built monuments to help predict positions and time, such as Stonehenge in England, the … Read More

Review of Altair Astro ED80 Used at Astrofarm Astronomy Centre Since we moved to France and set up the CEM60 in the observatory, I have only had one telescope on the mount, the Altair Astro ED80. I will be writing this review as a lay person who is using equipment for both Digital SLR and CCD cameras with narrowband filters. Therefore; there will be no long drawn out mathematical formulas and I will not be writing about the technical aspects … Read More

Review of IOptron CEM60 mount Recently installed at Astrofarm Astronomy Centre Last night I managed to spend some time getting to grips with the IOptron CEM60 mount. If like me, all you have been used to up to now is standard hand controllers then the CEM60’s display will seem a little daunting to begin with. This is, however, only until you read the user manual, something I never used to do, and then it becomes a wealth of information from … Read More
