Caption: The Cat's Eye Nebula (NGC 6543)
Green and blue filters were used for the [OIII]5007 emission: two colours were used for a single emission line because of the large dynamical range of the nebula+halo (there is a contrast of 1 million between the faintest and brightest structures detected), and the objective was to display the three different components of the nebula, i.e. inner nebula, first halo with the (in blue) rings, and outer filamentary halo. Red is instead [NII]6583. The image is the deepest ever obtained of NGC 6543.

Caption: Part of Rosette Nebula
Imaged with ALFOSC through the H-alpha filter. The Rosette Nebula is an emission nebula in the constellation Monoceros at a distance of about 4500 light years. It surrounds a cluster of young stars. The filamentary structure of the dark cloud is prominent and the main elephant trunk feature in this image appears twisted like a coaxial cable. In collaboration with Per Carlqvist, the Alfvén Laboratory, a new theory has been developed describing the formation and evolution of twisted filaments.

Caption: M15
Observed with the NOT 1024x1024 CCD camera. The image is composed of 3 individual 10 min exposures through b, v, and y Strömgren filters. The seeing of these images was about 0.5 arcseconds, the field of view is slightly under 3 arcminutes.
