My rig setup was a Lunt LS60T-Ha telescope and the new TIS DMK 51AU02.AS in prime focus. I can capture a full disc with the 500mm Lunt in a single AVI file.

On May 12th, 2012 members of our astronomical association gathered to share their experiences about astrophotography topics. Before others arrived, I managed to capture some images using the observatory's 200/2470 D&G refractor and the excellent DMK 41AU02.AS camera, with a Herschel wedge and Baader Continuum filter. The sky was a bit hazy but the image was very steady, I was suprised to see the small details.

On May 10th, 2012 students at Hopewell Middle School in a suburb of Atlanta, GA witnessed and imaged the largest sunspot anyone has seen in years in Active Region 11476. We were able to capture this highly detailed image of the Umbra, Penumbra, granulation and surrounding "pores" or newly forming spots as they broiled with magnetic activity. The spot is now aimed squarely at Earth as spaceweather forecasters around the world try to determine what may happen next. We used an Explore Scientific 127mm APO refractor and a Lunt Solar Wedge with a DMK 41AU02.AS camera to image the region.

Thank you to all who participated!

This is my Solar Ha refractor telescope, it’s a PST Stage Two modified Lyra Optics 4″ f/11 refractor telescope using DMK 41AU02.AS and DMK 21AU04.AS usb cameras for the imaging, more information is at http://www.photosbykev.com/wordpress/2011/11/29/pst-modifications/.

One from the morning of the 11th Febuary 2012. F20 with the F10 C11 SCT/DBK 21AU618.AS (YUY2 + unspecified codec) 2400/8000 stacked in Autostakkert processing in Registax 6 & Paint.net

The image was taken by Alfred Tan in Singapore on April 26 2012 at 10:00 am with a DMK 41AU02.AS camera on a Borg 76mm achromat fitted with a Solarscope SF50mm H-Alpha Single etalon filter. 1,800 selected frames from a 2 minute video were aligned and stacked in Registax 6 and colours added in Photoshop CS3. The DMK camera has not failed to amaze the local astronomy community with clear solar disk details and sharp prominences on the limbs. It is one of my most-used imaging camera and a worthwhile investment.

Beneath the huge prominence is Sunspot 1459 and further after the two filaments is Sunspot 1465. There was excitement on April 25 2012 because Sunspot 1465 has developed a "beta-gamma-delta" magnetic field that harbors energy for X-class solar flares.

Mars on the 17th of April 2012. F10 C11/DBK 21AU618.AS @ F42. 2500/20,000 stacked.. Relatively poor seeing however Autostakkert did a fabulous job in sorting the good and the best frames.

Saturn on the 8th April 2012. F10 C11/DBK 21AU618.AS618 @ F30. 4000/10,000 stacked. Very good seeing.

Dear amateur astronomers,

The ATT is Europe's biggest exhibition especially for amateur astronomers. You will find state-of-the-art telescopes and accessories as well as used and homemade instruments. Here you meet manufacturers and experienced amateur astronomers from all over Europe to share your thoughts with. Furthermore the ATT offers a platform for public presentation of observatories and astronomy clubs. In short, this is the place to be for anyone who is interested in astronomy. You will get plenty of ideas and inspirations for your hobby. Come and find out for yourself, and we are looking forward to meeting you at the ATT in Essen, Germany.

Our new website has been online since the beginning of 2010. Here you will find up-to-date information and all kind of interesting things about the ATT event. Following the upcoming ATT, we will publish photos and reports of the event on this site.

Your ATT Team of the Walter-Hohmann-Observatory

At the ATT in Essen (Germany), you will find the The Imaging Source Astronomy Cameras by all the official resellers who expose there: Astroshop.de, Baader Planetarium KG, GANYMEDES (NL), Intercon Spacetec GmbH, Lichtenknecker Optics N.V. (B), Neumann Gerd jr., Optische Instrumente, Teleskop-Service Ransburg GmbH and Teleskop & Sternwarte Zentrum (A).
