How to optimize your imaging performance
This lecture will show some important problems concerning astronomical imaging and ways how to deal with them. The main topics are:
- All about tubecurrents
- Seeing and Sampling - the myth of the 2” per pixel rule
- Residual Bulk Images (ghosting) - a problem of almost all full-frame CCD cameras which is not considered and/or recognized by a large number of astrophotographers.
Speaker: Wolfgang Promper
Narrowband image processing workflow
Jukka's lecture includes the latest version of ToneMapping (suitable for broadband (L)RGB-images as well). Main topics of his workflow:
(*) Processing calibrated, stacked and stretched image data by separating high and low signal/noise objects. (*) Processing the actual object, without stars. (*) A method to build a master luminance from narrowband elements. (*) Color combine and fine tune of starless color channels. (*) Star color and size processing as a separated element. (*) Finally combining processed elements back together, with zero data loss, byte to byte accuracy.

Hacienda los Andes, a new astrophotography destination under world class skies
Right next door to the professional observatories of Cerro Tololo, Gemini South, SOAR and the LSST, a new venture is starting operations at 1200m altitude in the chilean Andes. The observatory, installed on a 500 ha hacienda is located in a secluded dark-sky area and will cater to visiting astrophotographers and visual observers alike. Daniel Verschatse, a belgian astrophotographer who has lived in Chile for more than 15 years, presents his quest towards establishing a destination that offers excellent skies, top notch equipment and the comfort of a quality lodge. Jose Joaquin Perez, chilean astrophotographer documents the presentation with his excellent astrophotography and some practical recommendations.
Speaker: Daniel Verschatse & Jose Joaquin Perez
Adaptive Optics: from astronomers to amateurs, where we stay and where we go
We focus on the basic concepts of adaptive optics and how it is implemented on professional telescopes, in particular with reference to the case of the adaptive secondary mirrors of the Large Binocular Telescope. The lecture will then explore the possible use of simplified AO techniques for "high-end" amateur telescopes.
Speaker: Paolo Lazzarini
TWAN-Style astrophotography: Tips & Tricks
Astophotos which include landscapes are always interesting for ordinary people. People feel the importance of saving starry sky when they see pictures of astronomical objects over historical and natural places that they know or heard about, even if they don't know a bit of astronomy. Because of that so many nature photographers and astrophotographers experienced shooting a place at night with their DSLR and wide lenses but why some pictures always looks different to us. More than science and art, there is untold tips & tricks behind TWAN pictures.
Speaker: Mahdi Zamani
Freeware image processing
Astronomy and in particular astrophotography is an expensive hobby/passion. Purpose of this lecture is to show you some of the most effective freeware tools available on the web in order to process our wonderful astrophotos.
Speaker: Nicola Montecchiari
Photography and the discovery of the Universe
When the photographic plate replaced the eye as the astronomical detector of choice 120 years ago, it revolutionised astronomy, much as the invention of the telescope had heralded a new era, 280 years before. It was soon realised that photography could detect radiation from the stars that was invisible, revealing new and exciting phenomena. With this came an understanding of the nature of stars, nebulae and galaxies and for the first time their astonishing colours were revealed. In this profusely illustrated talk I will briefly review the rich history of imaging in astronomy, from Galileo to modern times.
Speaker: David Malin
Lucky Imaging
During the last decade the quality of planetary imaging has seen a dramatic development. Cheap webcams make it possible to produce thousands of pictures in a short time. With freeware programs like Giotto or Registax it is possible to select and add the sharpest pics with fantastic results. This speech shows the possibilities of planetary imaging techniques in the field of deepsky photography.
Speaker: Bernd Gährken
The natural night sky
It is nowadays difficult to find a natural night sky, unpolluted by light or other man-made emissions, especially in the Northern Hemisphere. While the natural, unpolluted night sky is never truly dark, astronomers have long known that its brighness and color varies with time, often quite quickly and for no apparent reason. Now, modern digital cameras can reveal these subtle changes in full color, and they are seen to exhibit a surprising range of hues and textures. In this talk I will describe and illustrate some of the phenomena associated with true darkness and show how even a small amount of light can affect our view of the universe.

First light at Prompt 7 - a joint German-Austrian-American remote telescope project at CTIO in Chile
The lecture is presenting the steps of planning for a semiprofessional setup at a prime site in Chile. It is showing site considerations as well as the importance of existing infrastructure and well balanced cooperation with professional astronomers. Technical features of the setup and the commissioning steps for fully remote operation are explained. First light images are shown together with a comparison of performance with my own Austrian setup. Planned expansions of the remote observatory setup.
Speaker: Johannes Schedler
Comet Photography
Amongst all the wonders of the universe, bright comets are the most impressive celestial phenomena. For 2013 Comet C/2011 L4 (PANSTARRS) and comet C/2012 S1 (ISON) are predicted to be very bright. The question that frequently arises is "How do I photograph a comet which is moving pretty fast". There are several considerations at imaging and processing to discuss.
