Mars Opposition & Total Mooneclipse

On July 27 2018 we had a public viewing event at our local observatory. It was a thrilling event, because at the beginning many clouds in southeast blocked the view. But "hope dies last" and the sky cleared more and more. About 1000 people visited our small observatory. Of course we had some portable scopes to offer a view to the moon and the red planet. Before and in between we could offer Venus, Jupiter and Saturn. Mars was not so pretty because at our latitude he is very low and the seeing is bad. However everybody was happy and... Read More...

Donating a minor planet during GAM2017

Yesterday, April 19th 2017, I had the pleasure to organize a very special event during GAM2017. Our local astronomical society (LAG) is running an observatory outpost in the northernwest countryside of Linz. This outpost is situated in the municipal area of Gramastetten. They host us for more than 20 years, so we decided to say officially thankyou to the local municipal and to all people there supporting us, especially our local landlord, an organic farmer who is supporing us in any matters for decades. How should we do this ? What's a convenient gift for this? ...... Right ! Naming... Read More...

Promoting GAM2017 at CEDIC'17 opening

Jerry Bonnell and me promoting Global Astronomy Month 2017 @ opening event of CEDIC'17 The Central European Deepsky Imaging Conference (CEDIC) was introduced in 2009 by the three Austrian hobby-astrophotographers Christoph Kaltseis, Herbert Raab and Wolfgang Leitner. It was the first international astronomical imaging conference throughout Europe and their personal contribution to the International Year of Astronomy 2009. Certainly it was not an accident that the date of the CEDIC encountered with the "100 Hours of Astronomy". Far from it! The organizers also wanted to support this project of the IYA with their conference. Since 2009 the conference takes place... Read More...

Worst lightpollution-attack in Austrian alps - ever!!!

Following some photographic impressions from my Tyrolean-astrofriends attacked by beams of light. A really hard attack to men and wildlife. Wondering events like these ( Festival of Light - Swarovski ) are authorized by the provincial government :-( ca. 500 floodlights ca. 1,000,000 lumens light intensity Hopefully this bad example does not catch on ! Some more picts showing the impact of lightbeams. Best regards Joe Read More...

Like many others in Austria we offered to visitors and walkers in our local town park a look to the Mercury transit on 9th May 2016. We had fine weather and we showed at our local Johannes-Kepler-Observatory the sun in white light and h-alpha light. Even at our outpost outside the city of Linz we had a little observing team showing this event to people of the neighborhood.Many people thought they can look to Mercury using sun eclipse glasses. They have been surprised that Mercury was so small and so they have been happy to see our smallest planet crossing... Read More...

GAM2016 - Global Star Party Event in Linz (AUSTRIA)

Yesterday evening hundreds of visitors could catch a glimpse through our telescopes set up at the main square of Linz ( the hometown of the famous astronomer Johannes Kepler from 1612-1626 ). For most of them it was the first time look through a telescope for their life. Getting in contact by this way we could tell much about astronomy, about AWB and our local astronomical society ( LAG ) and observatory. I am sure we could enthuse many of them with astronomy. The first time sight of Jupiter and his moons and the look at the surface of the... Read More...

Some astonishing details on Aldebaran's occultation by the moon.

On December 23rd 2015 an interesting detail was captured here at our local public observatory (Kepler Sternwarte Linz/Austria). Herbert Raab (chief of our local association) used an DSLR and our 130mm APO to make a video of the occultation. Due to the fact the RedGiant Aldebaran has an angular diameter of 0,02" (arcseconds) - which is equal observing a human hair at the distance of 500 meter !!! - the star did not suddenly disappear. The Moon's speed was about 0,55" per second which is equal ~0,01" between single videoframes - so we could capture the "fading-out" of the star.... Read More...

Different kind of Lunar-eclipse-observing (an attempt to make an indirectly Lunar Eclipse observing)

Due to cloudy weather, there was no chance to make an observation of this year's Super-Moon-eclipse. At first the local weatherforecast in the north of our hometown Linz/AUSTRIA wasn't so bad ....... ........ but when we arrived at our observing location we had following scenery: So what could we do ? Hope dies last and we decided to stay to wait for some holes in the clouds ..... they didn't come :-( In the meantime we used a DSLR, using a 8mm lens and took some pictures showing the cloudy sky during the whole time. So we decided to make... Read More...

One week meeting, listening and talking to people doing astronomy outreach programms everytime and everywhere around the globe. That happened at CAP2013 in Warsaw. Where else someone could feel better the joining spirit of astronomy and of our all ONE SKY ? So this was one of the reasons for me to join CAP first time. Of course, knowing that some AWB-people will join it, was one more reason to fly to Poland - the homecountry of Nicolaus Copernicus. Following some of my personal photographic impressions ...... A nice monument near the center of Warsaw remembering one of the most... Read More...

It isn`t easy to come in contact with Thailand-Astronomers. My first attempt to meet some members of The Thai Astronomical Society in Bangkok failed, even I had some contacts by e-mail there was no opportunity to arrange a meeting during my stay. After my roundtrip to Cambodia I returned again to Thailand to visit northern parts of the country. Here I tried again to come into contact. Again some e-mails awaked my hope. But the same: When I arrived nothing happened :-( So I took matters in my own hand and went up to the highest montain of Thailand, the... Read More...
