Yuri Beletsky

Yuri Beletsky is a professional astronomer at Carnegie Las Campanas observatory in Chile. His scientific interests encompass young stellar objects and chemistry of interstellar medium using optical and infrared spectroscopy. Besides his professional work, Yuri is an avid astrophotographer. Recently he mostly focuses on nightscape photography and high-resolution panoramic wide-field imaging.


Christian vd Berge (NL)

Christian vd Berge has only started with astrophotography in June 2012, basically when he 'discovered' the amazing results amateur astrophotographers can achieve nowadays with relatively simple (!) equipment and a normal DSLR. He had been interested in cosmology for years already and was active with (wildlife) photography as a hobby as well. Christian started to combine these interest areas by photographing the night sky, DSO's in particular. Having this background in 'regular' daytime photography he focuses a lot on the aesthetics of the resulting images in general and pay particular attention to composition and to 'soft' processing with attention to colour preservation in stars.

Adam Block (USA)

After graduating in Astronomy and Physics at the University of Arizona in 1996, Adam Block created and developed the core public observing programs at the visitor center of Kitt Peak National Observatory for the next 9 years. Through the generosity of Joe Schulman, for providing a telescope, and the foresight of Dr Peter Strittmatter the creation of what is now called the UA Science Mount Lemmon SkyCenter began in 2007. The SkyCenter represents the culmination of Adams efforts to do public outreach and share his passion for astronomy. Adam Block is regarded as a world-renowned astrophotographer. Throughout the years Adam has developed specialized techniques for processing astronomical images. Having honed his craft he now demonstrate these ever-evolving processing ways as part of workshops and tutorials he makes available. In Robert Gendler's recent book, called "Current Concepts in Astronomical Image Processing", Adam explains in one chapter some of the fundamental and innovative steps he uses when processing images. Today images Adam produces are used as references by amateur and professional astronomers alike. In addition to his work at the SkyCenter he also writes a monthly column, called "Cosmic Imaging" for Astronomy Magazine about CCD image processing.

Jerry Bonnell (USA)

Dr. Jerry Bonnell received a Ph.D. in astronomy from the University of Maryland in 1987. He has since enjoyed working on a variety of astrophysical satellite projects at NASA's Goddard Space Flight Center including the Cosmic Background Explorer, the International Ultraviolet Explorer, the Compton Gamma Ray Observatory, and the Fermi Gamma-ray Space Telescope. Author of popular books, reviews, and magazine articles on astronomy and high-energy astrophysics, Dr. Bonnell is also a founding editor and author of the Astronomy Picture of the Day (APOD), begun in 1995.

Justin Kabaus (AT)

Justin Kabaus, born in 1972, lives in Gallneukirchen near Linz and is an active visual observer and astrophotographer. In his day job he is active in the field of event technology. Justin started to be interested in astronomy as a young child and at the age of 15 he got a C8 that was mainly used for visual observation. Using his father's DSLR and intervalometer he started experimenting with time lapse videos. 2010 he decided to combine the two interests and his first astronomic time lapse was shot. Since 2013 he started to improve the procedure of making smooth day to night transitions.


Nicolas Kizilian (FR)

Nicolas Kizilian is a French astrophotographer interested in astronomy from a young age. At the age of 14, he started doing astro imaging on film with a 200mm SCT, which he still uses 25 years later. Over the past few years he has specialized in narrowband CCD astrophotography using a wide range of instruments from 66mm refractors in his backyard to 600mm professional grade observatories. His latest images have been published in multiple magazines and websites, and noticed as they were produced from limited resources.

David Lindemann (CH)

David Lindemann is a Swiss software engineer who founded a computer engineering service company active in the geographic and network information systems. David's career in astronomy started in Oct 2004 with a small 6" Newtonian telescope for visual observing. In 2008 he joined the observatory of Vérossaz, a small village nested at 800 meters at the foot of Swiss Alps. Since 2010, David captures the deep sky objects with various lenses, a modified DSLR and a CCD camera. At present, he is working in his own observatory in his backyard. His work in astrophotography is characterized firstly by the technical and scientific challenges posed by the capture of celestial objects and then, for aesthetic sensibility, philosophical and poetic that allow transform them to beautiful and colorful images. His favorite subjects are mainly emissions nebulae that populate our Milky Way. To capture the beauty of these fascinating objects, David developed his own narrowband imaging techniques including own software like SkySurveyor, which he offers to the astrophotography community for free!


Giovanni "Johnny" Paglioli (IT)

Giovanni Paglioli, born in 1967, was very young when his father woke him up for assisting the first landing of man on the moon... Since then he began to develop the passion for astronomy. Johnny's title of study are various, from art to audio engineering (that is now his actual main job). Since the 80's he has started doing astrophotography and, in the beginning of the 90's Johnny has founded a company that worked for television and film industry in the digital environment. His competences about digital imaging evolved (He worked as a 3D artist, digital compositing and director of photography). Johnny has had a long collaboration with Officina Stellare team. All these competences drive Johnny to experiment digital image manipulation techniques that he now includes in his workflow for astro imaging.

Vicent has also successful experience in forensics, successfully working as an image processing specialist for the Spanish National Police department.


Wolfgang Promper (AT)

Wolfgang was born in Australia, where he got his first small telescope at the age of 5. He was introduced to the night sky by his father. In the 1970s he relocated to Austria with his parents and when comet Kohoutek showed up, he got a 114mm reflector. Fascinated by the beauty of our nightsky Wolfgang started with chemical astrophotography in the early 1990s and with CCD imaging around year 2000. He is now working mainly with a remote observatory in Namibia and with his local observatory, located 20 km to the east of Vienna. Wolfgang's fantastic colourful images showing his unique processing style are renowned wordwide and were published internationally. His main interests are image processing and all the technical parts of modern astrophotography.

Evangelos Souglakos (GR)

Evangelos Souglakos lives in Athens, Greece and works as an IT systems engineer. Since his early student years he had a passion and an inclination for physics and astronomy. The thought of buying a telescope and a camera came at 2005 when Evangelos began to discover that amateur astronomy has made great strides due to technological development. About a decade ago, photographs of celestial targets, which for years it seemed unrealistic to capture with amateur equipment, suddenly began to fill websites. The thought of framing deep sky objects in a picture with his equipment was enough for him to deal with deep sky astrophotography. A lot of telescope types, CCD cameras and other equipment have now passed from his hands during this decade. His observations usually take place in his country house which is situated in a 'dark sky' location in southern Greece.

Sara Wager (UK/ES)

Sara Wager is a UK expat living in Spain. She began astro imaging in 2010 with fairly basic equipment and quickly realised that this was an area she really loved and wanted to explore. Today she has a garden observatory and uses a couple of telescope-combinations to capture her targets. Her true favourite is narrowband imaging. She had two APODs, one EAPOD and three times an AAPOD2. Further she won several competitions and had numerous published images. She loves the creativity and freedom that she feels narrowband allows and is always experimenting with different image processing techniques.

Astro Paradises - Dark Sky Places

Capturing dramatic views of the night sky with the landscape can be very challenger. Sometimes, because the sky is not dark enough or the beauty is not so well visible at first sight, but we need to find it and express it in an attractive way. Some images can be planned with time, but other ones are totally unexpected, when suddenly the nature show us a rare phenomenon in the sky that we were not expecting to find. Astrophotography of Landscape is a mix between science, beauty and art, letting us reaching more people in many different ways. In this lecture we will make a short travel across some of the best skies on earth, what I called "Astro Paradises", some are the base of the largest and most advanced telescopes working on Earth, and others are like the latest "protected pearls" in Europe, places where the people can handle daily with modernity without filling the sky with light pollution, closing the dark window that allow us to visual access the beauty of our Universe. You will notice that the quality of the sky makes the difference! With the right choice of lens and camera, sometimes, we only need a quarter of a minute to fully reach a magnificent result!

Speaker: Miguel Claro


10 tips for better stars in your (DSLR) astrophotos

The stars in an image can really make or brake your astrophotos. Too often we ignore them and they end up being over processed and a major distraction instead of a beautiful, subtle and colourful element in our pictures. In this session we will take a look at 10 ways to improve both our image acquisition process and post processing in PixInsight in order to get subtle and colourful stars.

Speaker: Christian vd Berge

Speaker: Yuri Beletsky


Beauty: Ancient Echoes in Astrophotography

Is beauty merely in the eye of the beholder? Why is astrophotography so cross-culturally captivating? By examining the kinds of things deemed beautiful, greater insight can be gleaned into the current trends in processing styles and how you can use this information in your own work.

Speaker: Adam Block


Struggling with the SNR. A walkthrough of techniques to reduce the noise from your captured data.

The presentation is focused on the techniques someone has to use to deal with photo processing challenges and reduce any type of noise from his published image. From capturing the data, pre-processing and eventually dealing with advanced algorithms, the purpose is always to extract the faint details, sharp and enhance the image without bringing the noise to the surface.

Speaker: Evangelos Souglakos


The devil hides in the dark - Challenges of deep LRGB images

Creating deep colour images is a challange. Gradients, artifacts from dust spots in the optical path, clipped highlights and background noise are the first major obstacles on our way to create a deep view. Preserving vivid but natural colours in the LRGB image also requires appropriate techniques. This lecture will deal with a couple of common issues on our way to a well-looking deep LRGB image. We'll discuss frequent problems with flatfields not perfectly matching our lights and see how we can work around that. Increasing contrast in our raw images will be the next topic. We will describe different ways to push the maximum out of the data and identify common problems with that including in particular how to keep background noise under control. Finally, we will talk about creating colour data from L, R, G and B raw images, particularly focussing on preserving a natural look in the image. This lecture will not discuss a complete workflow but rather focus on the mentioned topics. All operations shown will be made with custom software such as Adobe Photoshop CS6, CCDStack and MSB Astroart.

Speaker: Stefan Heutz


APOD on the World Wide Web

After over 20 years of editing Astronomy Picture of the Day (APOD), a website older than Google, Jerry Bonnell is still awed by the way art and science come together in astronomical images. During its history, APOD has been an ardent supporter of the astroimaging community, showcasing images from amateur observatories and night sky photography from planet Earth along side those produced by space-based observatories and robotic spaceships. Jerry will discuss recent APOD trends and submissions with an eye toward those from the amateur community.

Speaker: Jerry Bonnell


Narrowband - From scope to screen

From Planning, data capture and processing - Three essential parts of narrowband imaging success. How to turn a black screen into an image to be proud of and avoiding some pitfalls along the way. Sara's lecture will include many useful Photoshop image processing techniques.

Speaker: Sara Wager

ID Workshop

Consistent image acquisition and processing

Wolfgang Promper will give an overview of his way of image acquisition and image processing. He will start with topics like evaluation of the sky quality as well as analysis of image data quality. The speaker will show image processing steps for maximizing the output without overdoing it. A main goal in Wolfgang's workflow are consistent results.

Speaker: Wolfgang Promper


Composing advanced LRGB images in false colors and creating wide-field mosaics

David Lindemann shows in this workshop his unique method of creating wide-field narrowband mosaics. He will give a deep insight in his freeware software SkySurveyor, a stand-alone tool, which offers all necessary steps for conducting such a demanding mosaic project: From mosaic planning including the usage of multi-bandwith background images from skysurveys like Digitized Sky Survey (Color), Hydrogen Alpha Full Sky Map, Wise All Sky (Infrared) and many others to automated capturing of images for each tile including telescope slewing, guide-star selection, filter wheel movements and image capturing. David will demonstrate also his advanced LRGB composition method for imaging in false color. This is an empiric method that allows to give an aesthetic feeling to narrowband astronomical images by giving them a lot of structural details and very pleasing color schemes.

Speaker: David Lindemann


The holy grail of time lapse photography

After a short introduction how to shoot astronomic time lapse videos, Justion will explain his way to master the "holy grail" of time lapse photography: a smooth day to night transition. He will give a deep insight in his workflow and how to use software tools like Adobe After Effects, Lightroom and LRTimelapse for your image processing. Additionally, planning of time lapse videos and tips regarding the right choice of equipment are treated.

Speaker: Justin Kabaus


Gradient correction in PixInsight

Residual gradients are one of the most common problems in astronomical imaging. In this workshop, the author will present an overview of the techniques and tools implemented in PixInsight to overcome this problem and will talk about his personal approach to these techniques. The workshop will be focused on the use of the new DynamicBackground tool, which has new functionalities and improved algorithms to yield a more accurate gradient correction.

Speaker: Vicent Peris


Problems are soluble

At times it may appear that there is no way forward when processing an image due to problems with the data. At other times it may be that the image you see on the screen is very different from what you see in your mind's eye and there seemingly isn't a tool that does the job for you. This workshop will highlight the idea that most problems can be solved by thinking about the problem differently and using tools in unexpected ways. Adam will demonstrate a handful of examples that will both inspire and inform you about creative processing methods.

Speaker: Adam Block
