IC4592 The Blue Horsehead

A very pretty object which is close to the Rho Ophiuchi complex. Its fine dust lit up by the bright star which is part of the Nu Scorpii star system (from an APOD). The dust reflects blue light best because the size of the dust grains matches the blue wavelength the best.

It also looks great with a wide field scope or a 200mm lens on a DSLR.
