Speakers (in alphabetical order) Link

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. Dr. Bonnell lives with his wife (an art historian) and two sons in Greenbelt, MD, USA.

Miguel has been a lecturer in two presentations of TEDx and is the author of the astronomy and photography book Astrofotografia - Imagens á luz das estrelas in Portuguese and the new photo art book "Dark Sky Alqueva - O Destino das Estrelas / A Star Destination". His images have travelled the world and have been published in many different media outlets, from the written press to TV stations, including some of the most prestigious international magazines and web pages such as NASA's Astronomy Picture of the Day.

Oliver Czernetz (AT)

Olivers interest in Astronomy raised back in 2011 at the age of 31. Although being a late bloomer, he was hooked from the very first moment, and pretty soon he found himself gazing at the Moon with a 3" refractor. Wondering how he could share this amazing view with friends and family, he started taking pictures through the eyepiece with a smartphone, and now, three scopes and a lots of trial and error later, he is imaging the deep sky with a 130/719 Tripplet Apo from his hometown Leibnitz in the southern area of Austria. Also searching for possibilities to improve his processing skills, he started to assemble images from the Digitized Sky Survey or the Hubble Legacy Archive, mainly for training purposes and to overcome the bad weather season. But like astrophotography itself, working with professional data also became a passion for Oliver soon, and has finally been rewarded with features as "Astronomy Picture of the Day" (APOD) in April 2014, March 2016 and May 2016.

David Martínez Delgado (ES)

Dr. David Martínez-Delgado (Spain, 1970) is the principal investigator of the Stellar Tidal Stream Survey at Astronomisches Rechen-Institut of University of Heidelberg, in collaboration with a team of high class astrophotographers from different countries. For the last decade, he has focused his attention on the tidal destruction of dwarf galaxies in the halos of the Milky Way and other nearby spiral galaxies. Dr. Martínez-Delgado has published more than 80 refereed papers in professional scientific journals and magazines and has given invited presentations at several international conferences. Dr. Martínez-Delgado is an expert observer and has participated in a large number of observation campaigns at the Roque de los Muchachos (La Palma), Calar Alto (Spain), Las Campanas (Chile), La Silla (Chile), VLT (Chile) and Paranal (Chile) observatories and with the Hubble Space Telescope.


Stefan Heutz (DE)

Stefan is a well known amateur astrophotographer from northern Germany and a fellow of the Royal Astronomical Society. He is one of Germanys most respected pioneer in ccd imaging, and many of his astronomical renditions have been addressed as a reference class for the equipment he uses. He cooperates with Wolfgang Ries, an Austrian amateur astrophotographer who manually shaped a 18" newtonian which they utilize together now.

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.

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 Peris (ES)

With an astrophotography career of nearly 20 years long, Vicent Peris (Valencia, Spain, 1980) has been working for the last 9 years at the Astronomical Observatory of the University of Valencia and at Calar Alto Observatory. His works have been published and awarded by some of the most reputed publications worldwide, such as APOD, Scientific American, National Geographic, Bad Astronomy Blog, and Sterne und Weltraum. 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 astrophotography aprox. 20 years ago. Nowadays his equipment is located in Spain and is used for remote imaging. Wolfgangs 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.

ID Lecture

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

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

Galaxy formation projects for astrophotographers

Dr. David Martínez-Delgado is well known for his scientific work on galaxy formation and evolution in collaboration with well-known amateur astrophotographers. In this presentation David will give an overview over his current projects with robotic amateur telescopes and telephoto lens, including: i) the Stellar Tidal Stream Survey; ii)the Dwarf Galaxy Survey with Amateur Telescopes (DGSAT); iii) the search for ultra-diffuse galaxies, maybe the darkest kind of galaxies ever detected so far. He will discuss the comparison of these observations and the predictions from the Cold Dark Matter theory together with their impact in this research topic.

Speaker: David Martínez Delgado

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

Compositing of different scale images for astrophotography

How to get good results using different scale digital images. Choosing the right images to compose. Different methods for alignment. Using Photoshop for the compositing. Different blending modes for an aimed result in Photoshop.

Speaker: Giovanni (Johnny) Paglioli

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.

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

How to get the most out of your "cheap" equipment

This lecture will focus on the good practice to achieve great images when you have little time and a tight budget: Choose the right equipment, how to spend more time acquiring images and less time setting up your gear, acquiring your sub-frames efficiently, practical tips for image processing.

Speaker: Nicolas Kizilian

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

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.

ID Workshop

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.

Composing Deep and Detailed Images from Professional and Amateur Data Sources

Ever wondered how professional astronomical images are made, and what it takes to create such beautiful, deep views on your own? Olivers workshop will cover all the way, starting with a general overview on the topic, showing preliminaries, advantages and possibilities of working with professional scientific data. While having a closer look at astronomical archives and portals like the Digitized Sky Survey or the Hubble Legacy Archive, we will learn how to mine them, how the data is organized and how to choose objects of interest with appropriate data sets available. The right set of tools for data registration, reduction and preparation will also be an important topic to discuss, as well as strategies and techniques on image assembling. Having our data sets ready, we will move our focus on combining the images as well as the processing workflow itself. We will learn how to create so called hybrid images, unique constructions assembled from various sources like Hubble or large ground based scopes, and we will even include your own amateur data as well! To top it off, Oliver's workshop will also offer a lot of processing tips like color mapping or star handling.

Speaker: Oliver Czernetz
