Lbn528 and Lbn532, dark nebulae in the constellation Cepheus (one of which is also called the Worm Nebula), are located just below the Dark Shark Nebula.
A difficult subject from my home (SQM 18.8 - 19.4), but the 11 evenings with hours of integration paid off. The last session with the L-Qef filter, lasting about 5 hours from St. Bartelemy, helped a lot, but the final processing gave me a hard time. All things considered, however, I think the result is good... improvable, but good.
PS. In my opinion, this portion of the sky has a lot to show...you just need a lot of patience.
