DWARFLAB Draco: Reverse Engineering a Rumored Telescope From Six Independent Clues
A telescope named Draco showed up inside the DWARFLAB app with no announcement. On its own, that would be a curiosity. Lined up against a patent, a wide-angle spec, and a trade show teaser, it starts to look like an engineering trail worth following.

DWARF 3 Squid Nebula (Ou4): Why the Duo-Band Filter Can’t Detect It
I had 21.5 hours of data on the Squid Nebula and a decision to make: keep shooting it, or give up and point the scope somewhere else. Ou4 is one of the faintest things an amateur telescope can attempt. It is nicknamed the Squid Nebula for its long, ghostly, tentacle-like lobes. I couldn’t tell from…

Seventeen hours on the Squid Nebula (OU4) and the blue I wanted to see
The giant squid (the deep sea creature, not the squid nebula) spent most of a century as the animal everyone knew was down there and almost nobody could photograph. There were beaks cut from sperm whale stomachs, severed arms hauled up in nets, the occasional carcass rolled onto a beach, every bit of it proof…

One Bad Dark Frame Almost Ruined My M13 Hercules Cluster
At 4:22 in the morning my phone showed me something I couldn’t explain in my M13 Hercules Cluster image. 561 frames of M13, the Hercules cluster, nearly at zenith, 9.74 GB of data collected while I slept. The Great Hercules Cluster is half a million stars packed into a sphere 145 light-years across, sitting 25,000…

Maximize Sharpness with DWARF 3 Techniques
What You Will Learn In this post I cover why DWARF 3 deep-sky images can look soft when zoomed in, what the telescope’s optics and image scale actually mean for resolution, how atmosphere, focus, tracking, and stacking each contribute to sharpness, how processing choices can either reveal or damage the data, and what practical steps…

I Pointed an iPhone 17 Pro at the Moon Through a NexStar 8SE. Here Is What Came Back.
Most people assume that serious lunar or moon photography requires a dedicated astronomy camera, a laptop running capture software, and a workflow that takes more time to set up than the session itself. I made that same assumption for a long time. Then one evening I walked outside with my Celestron NexStar 8SE, clipped my…

Star Trails with the Dwarf 3: First Test of Star Trail Mode (720 × 30s)
DwarfLab recently added a dedicated Star Trail Mode to the Dwarf 3 app. This is my first test of it. 720 frames at 30 seconds each, six hours total, stacked in real time by the app with no post-session processing required.
