Dwarflab Draco vs $5K Custom Rig: RAW Data Analyzed in PixInsight
Quick summary· AI-generated
Wido Oerlemans performs a detailed technical comparison of RAW files captured with the unreleased Dwarflab Draco (90mm f/3.8 catadioptric with active autoguiding and internal sensor de-rotation) against his custom $5,000 imaging rig featuring an 80mm APO and ASI2600MM Pro camera. The Draco's 5-minute exposure capability and dual-band Hα/OIII filter ($1,399 base model) are designed to eliminate equatorial wedge setup, polar alignment, and complex workflows typical of traditional imaging chains. The analysis examines whether the Draco's internal de-rotation system actually delivers round stars in Alt-Az mode, signal-to-noise performance on deep-sky emission nebulae, and practical usability—key metrics for assessing whether a $1,400–$1,600 smart scope can genuinely compete with multi-thousand-dollar custom rigs at image quality.
Excerpt from Wido's AstroForum
Dwarflab recently released the first RAW images captured with their upcoming Draco Smart Telescope. As someone who spends far too much time obsessing over astrophotography gear, I couldn’t resist doing a deep dive into these files. I wanted to analyze what this scope is actually producing and compare it directly to a stacked image of the exact same object shot with my custom $5,000 astrophotography rig including my 80mm flatfield apochromatic telescope and asi2600MM Pro cooled camera.

If you aren’t familiar with the Draco yet, it’s a compact catadioptric, mirror-based Smart Telescope featuring a 90mm aperture and a 340mm focal length (f/3.8). What makes it particularly interesting for amateur astrophotographers is its tracking design: it aims to track for up to 5-minute exposures in Alt-Az mode using active autoguiding and an internal rotating camera sensor to eliminate field rotation.
Draco’s active autoguiding and internal sensor de-rotation system
In practical terms, the workflow involves placing the Draco on a table or balcony, selecting a target in the mobile Dwarflab app, and letting the scope locate, track, and capture the object automatically with exposures up to 300 seconds. Shooting 5-minute sub-frames allows you to gather a massive amount of light and build a strong signal-to-noise ratio—essential for pulling out faint, wispy structures in deep-sky emission nebulae using its internal 13nm dual-band filter.
Furthermore, the Draco’s internal camera sensor de-rotation system is designed to make setting up in EQ mode (or lugging along an equatorial wedge) completely unnecessary. On paper, the de-rotating sensor continuously counters field rotation during tracking, which should ideally deliver round stars across 300-second exposures directly in its native Alt-Az configuration.
I emphasize “on paper” because the Draco is not officially released just yet. As of early October 2026, Dwarflab’s target launch is still roughly three months away, with first production units slated to ship in early 2027 and only pre-orders available right now. The base model, which includes a dual-band Hα/OIII filter, is priced at $1,399, while the SHO version comes in at $1,599 and adds an SII/OIII dual-band filter. If real-world testing proves it can genuinely compete with a $4,000 to $5,000 custom rig, it represents a substantial shift in accessible astrophotography—especially considering you bypass the typical cable management, polar alignment…
