Forming Sunspot in CaII K, White and Solar Continuum

A combination of white light (ND3.8), Solar Continuum and CaIIK Line. The forming sunspot is clearly visible on all three pictures.

The Andromeda Galaxy M31 was photographed. Total exposure time was 3hours and 32minutes. All together I made 253 pictures taken with setting of 30s and 60s exposure time and different ISO setting.

Setting : Nikon D7500 and TLAPO80/480 f/6. Camera control with DigiCamControl for exposure time >30s. Raw data converted to DNG and stacking using DeepSkyStacker. Final editing using CS4.
