Combined Beginner and Intensive
PixInsight Workshops
By Vicent Peris
6 – 12 and 16 – 22 May 2016, Tucson, Arizona, USA
These workshops will give amateur and professional astrophotographers alike a chance to work with Vicent Peris, a member of the PixInsight Development Team, and learn directly from him the techniques and tools he has developed on the PixInsight Platform.
The workshops will take place at the Tanque Verde Ranch in Tucson, Arizona, USA, from May 6 to 12 and May 16 to 22. Starting on May 6th, the first workshop will be a combined beginner/intensive like the one we offered in 2015. This combined workshop will offer the user a more flexible opportunity to learn image processing. On the weekend an introductory workshop to PixInsight and the basic image processing techniques will be offered for up to 40 people. Following this workshop, a 4-day intensive workshop will review more advanced techniques in a fully personalized learning experience for up to 12 people.
In order to fulfill the high demand of the last year, we are also offering a second intensive workshop on the following week, from May 16 to 22.

The workshops will take place at the Tanque Verde Ranch in Tucson, Arizona, USA, during the following dates:
- May 6 to 8 – Beginner Workshop

Workshop Methodology
This workshop has been designed with a special focus on the active participation of the attendees. Each registered participant will be provided with a personal account on PixInsight's Endor file server, where he or she will be able to upload raw data that will be worked out during the workshop. In this way the participants will have the opportunity to apply and understand the concepts and techniques described in the context of their particular imaging conditions.
The full processing example will be based on the uploaded data, so it is strongly recommended to upload full data sets. The participants will be able to upload their data until May 15th. Participants should accept the use of their data exclusively in the workshop by the other attendees. Selection of the most appropriate data sets for the workshop is up to the teacher.
Attendees should bring their own laptop computers. A valid commercial or trial PixInsight license will be necessary.
Two Workshops in a Single Event
The idea behind the organization of this event is versatility. The weekend workshop should work for all the people looking for an introduction to PixInsight and an in-depth review of the basic image processing techniques.
People looking for a more extensive learning experience can register into the full workshops. For the first intensive workshop, the weekend will give the required knowledge basis to keep learning during the following days.
What to Expect from the Weekend Workshop
This workshop will introduce you to the PixInsight platform and the basic image processing techniques applied to astrophotography. You'll get benefit of this workshop even if you have very little experience in PixInsight because we'll start from scratch on the software usage on Friday afternoon.
Perhaps the weekend program seems very basic for this workshop, but we'll do an in-depth review of the LRGB and dynamic range compression techniques at a slow pace. They are the most widely used techniques in astrophotography and therefore it's of extreme importance to understand them including the minor details. We'll talk about image linearity and delinearization techniques. And we'll work with some important tools in PixInsight under different scenarios, like DBE, BackgroundNeutralization, ColorCalibration or HDRMT. We'll also review the basic masking techniques as well as some basic narrowband information.
On Sunday we'll work together on a full processing example, starting from the image inspection and preprocessing stages to the processed image.
What to Expect from the Intensive Workshops
People staying in the intensive workshop will learn additional techniques for narrowband imaging as well as an additional full example.
The most interesting part of this workshops is when everyone works with his/her own images. This way, people learn how to apply the recently learnt techniques to their own photos. Vicent will guide everyone in the particular processing steps to achieve an optimal result. At the end of each image processing session all the results as well as possible alternative processing steps are discussed with the whole group.
Workshop Documentation
USB Thumb Drive
A thumb drive with all the images, projects and process icons will be provided to all the participants.
Workflow Charts
Each participant will be given a full set of PixInsight workflow charts describing the techniques reviewed during the weekend. Covering the main concepts in a visual style, these charts will help you to carry out your own work at home.
Participants of the intensive workshop will have additional workflow charts describing the techniques reviewed from Monday to Wednesday.
Intensive PixInsight Manual
Each person attending the intensive workshop will be provided with a workshop manual. This manual will have detailed articles on start to finish examples. The manual is delivered as a PDF document.
Workshop Program — Beginner/Intensive
Learning to Navigate the PixInsight Platform
An introduction to the PixInsight platform and its graphical user interface.
LRGB Composition Techniques
We'll review the most basic image processing techniques for astrophotography. It's strongly recommended that participants watch Vicent's videotutorials about color calibration and LRGB techniques prior to attending the workshop.
Dynamic Range Management Techniques
PixInsight has a highly automated workflow for the dynamic range management of the image. We'll review the use of HDRComposition and HDRMultiscaleTransform tools as well as basic masking techniques for local contrast enhancement.
The Hubble's Palette
Building a Hubble's palette composite in PixInsight is extremely easy. We'll review an effective workflow composed of only four steps that gives a good tonal representation in these narrowband images.
Start-to-Finish Processing Example
Based on users' data sets, the teacher will build an start to finish example. This example begins with all the image inspection an preprocessing steps and goes through all the processing steps to the finished image.

About Vicent Peris
With more than a 15-year career as an astrophotographer, Vicent Peris (Valencia, Spain, 1980) has been working for the last 7 years at the Astronomical Observatory of the University of Valencia (OAUV). He is now leading the world-renowned astrophotographic programs at Calar Alto Observatory (CAHA) with the 3.5 meter and 1.23 meter Zeiss telescopes, the latter in collaboration with the Documentary School of Astrophotography (DSA), applying innovative image processing techniques and software tools. This is the first astrophotography project in the world with access to the observational time of professional telescopes.
You can see some of the published images of the Calar Alto project on the Gallery section of PixInsight's website, as well as some of Vicent's articles about his image processing techniques on the Processing Examples section.
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 is also the official astrophotographer of the ALHAMBRA Survey, a deep cosmological survey conducted by an international scientific collaboration, acquired from Calar Alto Observatory using the 3.5 meter Zeiss telescope. This survey is the first in the world to use a new instrumental technique known as photometric redshifts, in which low-resolution spectra for each object in an image are obtained by using a large, 23 narrow-filter set covering the 3500 – 9500 angstrom light band. You can see some image samples at Vicent's website.
Vicent has also successful experience in forensics and is currently working as an image processing specialist for the Spanish National Police department since two years.
