Teleskop service 8″ Boren simon power newtonian, Skywatcher NEQ6 pro mount,Atik 383L+ camera, motorised filter wheel and Astronomik filters.

Open star cluster in the constellation Taurus.

Good naked eye object that looks great even from my light polluted back garden.

The blue colour is caused by the star light reflecting on dust more in the blue spectrum rather than red. The same effect as the blue sky here on earth.

Used a Photoshop layer mask with an unstretched image so the stars where not too bright and obscuring the faint nebulosity.

RGB image with 3 hours and 0 minutes of data. 24 x Red, 24 x Green, 24 x Blue 2.5 minute exposures.
