Mark Johnston
I have been fascinated by the night sky since I ‘discovered’ Saturn with my 60mm refractor at the age of 10. An APOD-winning astrophotographer, I have been published in Sky & Telescope, Astronomy Magazine, and Space.com. As a NASA Solar System Ambassador, I have conducted thousands of public outreach programs and am a registered cruise ship speaker on astronomy and space science, as well as a Director of the Phoenix Astronomical Society. I frequently post astrophotography images, news, and tutorials on social media. My solar imaging and videos are particularly popular, and I have conducted extensive research on solar cameras and solar image processing techniques.

Mosaic Mastery: Delving Deep with PixInsight's Photometric Tool

Part 1 - Introduction to Data, Creating Master Frames, and Preparing for Combination In the first section of the webinar, Adam will guide you through the data that has been selected, the data management for mosaic processing, and the creation of the master frames. He will then demonstrate what to look out for when preparing your frames for the subsequent processing steps. Part 2 - Colour Calibration, Background Extraction & Mosaic Anatomy After creating the RGB masters, Adam will explain the mosaic anatomy and how the photometric mosaic will process the panels you have generated. He'll also discuss how this method extends beyond the 2x1 mosaic used in this example. Additionally, we'll examine how to deal with the edges of the mosaic, their overlaps, and special considerations for wide field-of-view instruments. Part 3 - Photometric Mosaic Script The photometric mosaic script is an essential tool for creating mosaics. Adam will walk you through all the configuration steps for this script, highlighting any exceptions and alternate processing approaches depending on your data. Part 4 - Gradient Correction, Post-Processing & Summary One challenging aspect of mosaic processing is gradient correction. Adam will demonstrate how, using the Photometric Mosaic script, you can adjust gradient compensation via a graphical interface. He'll also offer post-processing tips for refining your mosaics and provide a summary of all the steps undertaken. Part 5 - Questions and Answers

Deep dive into Telescope Live - Data Management & Planning and Submission of a Mosaic

In this live webinar on the usage of the Telescope Live Platform, Alexander Curry showcased how to improve data management of your data and how to plan and submit mosaics with an Advanced Request. Part1: Data management in astrophotography is an important factor to both speed up your workflow and conserve that all important disk space! With a few tips and tricks for managing your raw & processed data on your hard drive you can make room for many more astrophotos! Part 2: Processing mosaics is a great way to expand the capabilities of your telescope, imaging a larger area of the night sky in a single image. However, setting up and acquiring that data can be half the battle, but in this webinar we will show you how to plan for a mosaic and select the best telescope for the job.

A New Approach to Narrowband Processing of NGC 3293

In this webinar, Nik Szymanek demonstrated a comprehensive post-processing workflow using the NGC 3293 Observation Bundle from Telescope Live. Leveraging the capabilities of multiple tools, including PixInsight, Affinity Photo, and the suite of XTerminator plugins (Blur, Star, and Noise XTerminator by RC Astro) Nik showed participants a unique glimpse into his process that frequently yields remarkable results. The journey begins in PixInsight, where an RGB FITS image is created and subsequently scaled alongside the H-alpha integration. Deconvolution is run using the BlurXTerminator plugin, and after some histogram transformations, the mono and RGB frames are combined into a pseudo 'LRGB' image, an Ha-SHO format that takes advantage of the high signal-to-noise ratio of the H-alpha data, utilizing it as a luminance frame. The stars are then extracted using StarXTerminator in PixInsight, creating a starless and a star-only version of the image. These are then further enhanced in Affinity Photo, using the Tone Mapping tool on the starless layer and color manipulation via Selective Colour. After noise reduction with NoiseXTerminator, the image is further refined with adjustments such as sharpening and scaling.

Generalized Hyperbolic Stretch - An Improved Way to Stretch Your Images in Pixinsight

Generalized Hyperbolic Stretch or GHS is a Pixinsight script designed to give you a new and improved approach to stretching your astrophotography images in Pixinsight. Adam Block will cover installing the script & module, the basics of the interface, the core principles of GHS, and the several use cases for this script. To install GHS, follow the instructions below: 1) From within Pixinsight, go to: Resources > Updates > Manage Repositories 2) In the Manage Update Repositories dialog, click the Add button 3) In the URL box, type the GHS repository information as follows: https://www.ghsastro.co.uk/updates/ 4) In the Add Pixinsight Repository dialog, click the OK button 5) In the Manage Update Repositories dialog, click the OK button
