Deep Sky Images
This section contains very few images because the sky over the New Millennium Observatory is rather bad for galaxies and nebulae imaging.
Moreover the deep-sky photography is not among the key project of the observatory, therefore normally I do not take long exposure of the sky, but the exposure time is optimize to get the highest limiting magnitude with the shortest time exposure, a technique that I currently use in the Valhalla supernova search.
All these pictures have been taken with the 0.36-m telescope of the observatory. Beside each photo there is a short data description.
