LRGB galaxy processing with SIRIL and Affinity Photo
In this tutorial series, Telescope Live co-founder Alex Curry guides you through the process of LRGB galaxy processing. Utilizing the free post-processing software Siril for the foundational work and Affinity Photo for advanced retouching, this three-part guide is ideal for beginners looking to harness the full potential of these tools.
Part 1 & 2: Foundation with Siril
- Start with an introduction to the dataset and the processing objectives.
- Learn to set up and stack data in Siril, laying the groundwork for a high-quality image.
- Advance into Siril’s post-processing features: color calibration, star subtraction in L and RGB images, luminance integration, saturation tweaks, and detail enhancement through denoising and sharpening.
- These two parts culminate in a complete, refined image using solely Siril, making it accessible for those preferring or limited to free software.
Part 3: Enhanced Finishing with Affinity Photo
- For those seeking to elevate their image further, this part shifts to Affinity Photo.
- Focus on advanced retouching techniques, including revisiting Siril’s output for final touches.
- Topics include luminance integration, intricate color work, saturation balance, sharp image sharpening, star overlay, and effective noise reduction.
Alex’s expert guidance ensures a thorough learning experience, from building a solid foundation with Siril to applying the finishing professional touches with Affinity Photo.
Faster PixelMath with Consolidated Icons in PixInsight
Staying organized is crucial in image processing, especially with your saved icons and processes in PixInsight. Accumulating a plethora of PixelMath expressions is common, but Warren Keller from Masters of PixInsight shares a technique to streamline this into a single icon, thereby accelerating your processing workflow.
Revealing Hidden Details with HDRMT in PixInsight
HDRMultiscaleTransform is a process that uses wavelets to compress mid to large scales, uncovering small details that might be concealed during a histogram transformation. The recent addition of the "To intensity" option has revolutionized this process. This option works in the HSI color space, preserving hue, saturation, and intensity, and integrates a modification to HDRMT by Russel Croman - ColourCorrected HDRMT. Warren Keller from Masters of PixInsight will guide you through the HDRMT process, including the new "To intensity" option. He will also compare it with the CCHDRMT script and demonstrate how HDRMT can be used to reveal hidden details in your images.
The future of exoplanets and how the public can get involved
Join us in a fascinating journey towards understanding the mysteries of worlds beyond Earth, a venture that captivates not just the scientific community but every curious mind. This tutorial, based on our insightful astronomy webinar, delves into the current state of exoplanet research and the exciting future that lies ahead in space exploration.
At the heart of this exploration is the European Space Agency's Ariel space mission, scheduled for launch in 2029. Ariel stands out as the pioneering mission dedicated to analyzing the chemical composition of a wide array of exoplanets, orbiting diverse star types. Its primary aim is to comprehensively study a significant and varied sample of exoplanets to answer pressing questions about their composition, the formation of planets and planetary systems, and the evolution of planets and their atmospheres over time.
Ariel's ambitious plan involves observing around 1000 transiting exoplanets. To optimize this survey, precise knowledge of the expected transit times of these planets is crucial, presenting a unique opportunity for collaboration across the astronomical community. This is where the ExoClock project comes into play. Developed by Anastasia Kokori and Angelos Tsiaras (the two guests of this webinar), ExoClock is an integrated, open project that focuses on monitoring the ephemerides of Ariel’s target planets.
The project is a call to arms for all - professional and amateur astronomers, as well as enthusiastic members of the public. By participating, you can contribute directly to the success of this groundbreaking mission. This tutorial offers an in-depth look at the Ariel mission, its objectives, and how you can be a part of this monumental step in exoplanetary research.
