Hey Everyone! New video published!

https://youtu.be/9_6CWppY22o?is=LHHjwc-n4amoPaNX

Weather can make or break an astrophotography session. In this video, I install the K&F Concept WiFi Weather Station at the AstroAF Observatory and integrate its real-time environmental data directly into my astrophotography workflow.

Kentfaith reached out and asked if I would be interested in checking out something from the K&F Concept catalog. After exploring everything from carbon fiber tripods to an electronic telescope eyepiece that could be really interesting for outreach and star parties, I found their weather station and immediately saw how it could fit into my observatory.

Hey everyone! I had to re-publish my solar mosaic video due to some technical problems with the initial publishing!

https://youtu.be/Wn86TizSfa4

If you’ve ever wanted to create a full-disk solar mosaic, this astrophotography tutorial walks through my complete pre-processing and mosaic workflow using a 13-panel solar dataset.

Beginning with stacked panels from AstroSurface, I’ll demonstrate how I prepare each panel for assembly, maintain a consistent appearance across the entire mosaic, and bring everything together into a seamless full-disk image. Along the way I’ll cover the role each application plays in the workflow, from enhancing fine solar detail in ImPPG, to final contrast adjustments in PixInsight, and ultimately merging and finishing the mosaic in Photoshop.

Cheers!
Doug

Hey everyone! Here's my Hercules Constellation and Surrounding Region image from my latest video of my Fully Automated Widefield rig:
https://youtu.be/Qi5wQOz0AEw?si=9QHAactqTg9HLHDa

This image captures a sweeping view of the Hercules constellation and its surrounding region, placing one of the night sky’s most recognizable constellations into its broader celestial context. Rather than focusing on a single deep-sky object, the widefield perspective reveals the intricate tapestry of stars that defines this area of the sky, while the Great Hercules Globular Cluster (M13) appears as a small but unmistakable beacon nestled within the constellation. The result is a view that emphasizes both the scale of Hercules and the vastness of the stellar landscape that surrounds it.

Hey everyone! New video published!
https://youtu.be/Qi5wQOz0AEw?si=9QHAactqTg9HLHDa

Astrophotography continues to evolve, and one of the projects I’ve been most excited about has been building a fully automated ultra-widefield imaging system around a manual Rokinon 14mm lens.

In this video I walk through the complete build of my new widefield astrophotography rig, from a fully disassembled collection of components to the finished imaging system mounted and ready for the night sky. Along the way we’ll discuss the design decisions behind the build, achieving the correct Canon EF backfocus, custom PA6-CF printed mounting rings, integrating a ZWO Astrophotography ASI533MC Pro cooled astronomy camera, ZWO FD-EOS filter drawer, Astroasis Oasis autofocus system, and preparing the rig for NINA automation.

Cheers!
Doug

Hey Everyone! Here's my final image from my latest video..
Decomposing Medusa Nebula | Looking Deeper At Your Astrophotography Data
https://youtu.be/HFEuOQSLgQg

The Medusa Nebula (Abell 21 / Sharpless 2-274) is an ancient planetary nebula located roughly 1,500 light-years away in the constellation Gemini. Formed from the outer layers of a dying star ~10,000 years ago, its tangled filaments and shell-like structure create one of the most fascinating narrowband targets in the night sky.

Hey Friends! New video published.

https://youtu.be/HFEuOQSLgQg?is=pHGG_DBrSUx-Q58N

Astrophotography is often taught as a sequence of image processing steps:
Do this. Click that. Apply this process.
But real image processing rarely works that way.

Every image presents different challenges, different opportunities, and different decisions. The most valuable part of the process isn’t memorizing a workflow. It’s learning how to interpret the data and make informed choices.

Rather than building an image of the Medusa Nebula from scratch, we’re going to work backwards through the finished result and decompose it into the individual components that shaped the final image.

We’ll examine:
• The contributions of Sulfur, Hydrogen, and Oxygen data
• Why some structures became focal points during processing
• How individual channels reveal different physical features of the nebula
• The importance of testing assumptions rather than forcing a result
• How data-driven decisions influence the final image

Cheers!
Doug

Hey Friends! New video published: Harmonic Drive Mount | From Idea to DIY Manufacturing.

Since the original HarmonicAF V1 prototype videos, this project slowly evolved into something much larger than I originally expected.

What started as a concept for a harmonic drive astrophotography mount gradually turned into a deep dive into design iteration, PA6-CF manufacturing, process control, CNC refinement, material science, and hybrid fabrication workflows. This project also evolved as a result of listening to your feedback and suggestions in comments and Discord and for that I thank you!

This video documents the engineering journey behind HarmonicAF V2 and the manufacturing systems that gradually evolved around the project along the way.

What you build transforms you.
