The Iris nebula (NGC 7023) and the dust clouds of Cepheus

The Iris nebula (NGC 7023) and the dust clouds of Cepheus

This is 1h58m (236x30s) of frames into the Cepheus constellation with the Iris nebula at centre frame. The shots were captured through a Sigma 105mm f1.4 at f1.4 on an unguided iOptron Skyguider Pro using a Canon Ra at iso 640. The lights were calibrated with bias and flats, and stacked/processed in Pixinsight.
