Orion in the Cold: A Night with M42 and the DWARF 3

Some targets announce themselves loudly. Others reveal their depth only after you’ve spent enough time with them to stop underestimating them.

The Orion Nebula is often placed in the first category. It’s bright. It’s obvious. It’s familiar. But on this cold winter night, M42 reminded me that familiarity doesn’t make a target simple, it just makes its challenges easier to overlook.

The first session of 2026 and it was planned with Orion in mind. The goal was straightforward: gather clean, stable data and let the nebula speak for itself. What really helped was the device thermal study to figure out how to reach temperature equilibrium to support a clean run with solid data. The filter choice in full moon conditions was obvious. More on all this soon in a separate post.

The first image is straight from the Dwarf 3 with simple “Auto” edit in Stellar Studio. No external stacking or post processing yet, but can’t wait to put the subs through Siril and Photoshop.

The second image was created by removing stars in Stellar Studio and a small edit in Snapseed (Adjust Tool->Click “AI”. Curves Tools->Select A01 preset)

The third image is based on the second. Used the new “Dehaze” feature … dialed it up to +100. Looks divine…
