Sharpless 155 from Telescope Live SPA-2-CCD
From time to time I obtain data sets from remote observatories. One of my favorite providers is Telescope Live with telescopes in e.g. Chile, Australia and Spain. One of the data sets I received, was HSO data from the diffuse nebula Sharpless 155, also known as Cave nebula, located in the constellation Cepheus.
Data calibration and registration and the final processing was done with PixInsight. The result was as follows:
