This is the result of the "first light"-frames after the replacement of the 2"-RCC1-corrector/QSI-combination by the 3"-Paracorr and the Moravian G3-16200.
For this image all nebulae (and the RBI-flash-artefacts) were subtracted from the RGB-image. Using Starnet++ starless versions were created from the Hα- and O3-stacks and the resulting image was integrated into the RGB-data.
