Cooling_3 image is clear and even

Checked the wether with met office, clouds are exopected to clear for the rest of the night

Finding the star by eye, alighning the tescope, using stllarium found it was Procyon

As it wasn't clear that the star is Procyon, checked with Rigel

Took images of the delta cep with no filter and with filters: red, green, blue and spectroscope. Aimed for 50 000 pixel value - the closest to the maximum possible p.v.

Exposure time was increased as different filters were applied, because different filters obsurb more light.

Cloudy weather led to taking many pictures for blue filter with longer exp time, 16 sec.
