Headphone Nebula – with UHC filter – March 2026

The first of two objects of the night. In fact, the first attempt at a run using new equipment. StellaVita and SkyEye24AC.

The first real deployment of my new setup.

ToupTek StellaVita astrocomputer and ToupTek SkyEye24AC.

I got myself a ToupTek StellaVita to permanently mount this compact astrocomputer on my Vixen VC200L.
In addition to my SkyEye62AM, I also picked up a SkyEye24AC for the VC200L.

The goal is simple: set up and start imaging! Ideally one or two objects per good night. I’ll explain what drives this approach in more detail in future posts.

What matters most to me: it worked right away – almost eerily so!
