Pleiades open cluster
Pleiades open cluster: On a clear sky, it is visible to the naked eye from the Northern Hemisphere as a bunch of individual points of stars and dust.

The general method I follow for deep sky objects is to take shots of not more than 1 min exposure each and then stack them using Deep Sky Stacker software. Then I process the stacked image using Astronomy Tools plugin of Photoshop or Lightroom. But the exposure times and other setting vary according to the object I select. The setup I use for most of the objects is 3 inch aperture/400mm focal length refractor and DSLR at prime focus. These two images have been taken using Celestron 11 inch Cassegrain reflector at 2800mm focal length.
