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.

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

Ancient Echoes of a Forgotten Sky

In this talk given by Adam Block, he will discuss how we portray astrophotography images and how our choices of field of view, resolution, and color affect how we process and publish our astronomical images. Adam will also discuss the theory of natural beauty, how we interpret beauty in both landscape and astrophotography, and where these preferences come from.
