My first attempt with the production version of QHY16200A Monochrome is a 6-panel mosaic composition for IC1396 and its surrounding area, including sh2-129 "Flying Bat Nebula," sh2-135 and sh2-132 in Cepheus. This area has tons of very faint nebulae and stars in the background then it is very interesting, and challenging, to image. Wider imaging area with fine resolution of the KAF16200 sensor enabled to describe the delicate faint star clouds.
