IC 1805 Heart Nebula
Photo description / processing
Added almost an hour of hydrogen sulfide during "nautical twilight" with a full Moon.
The goal was to test exactly this equipment setup.
The test was partially successful - in the middle of the session, there was an autofocus failure and a significant portion of the material went to the trash. On the remaining data, both sulfur and hydrogen-beta are visible, despite not the most favorable shooting conditions.

First light of the arrived telescope with a field flattener. Although it's a doublet, I don't see obvious chromatic aberration. It will go under the Askar 103 APO barrel as a second telescope, it has a 0.8 reducer so the same focal length of 560mm. There is no complete darkness yet, I was shooting at dusk.

And I don't plan to specifically, unless one happens to be in the field of view.
