LDN 1089 with OSC – August 2026

LDN 1089 with OSC: one night in August 2026, 4 h 10 min with the Baader Apo from my garden.

The final image before my trip to Spain. That’s why I only got around to developing it now, in September.

Actually, this was the first image I captured with the Apo using the ToupTek Stellavita. As I mentioned before, I was already having issues with my old system.

I now have a few more ideas for making the Baader Apo setup a little more streamlined.
