B33 - The Horse Head Nebula, 16.02.2002 (22:17 UT) Resolution: 3.14 arcsec/pixel Camera: Vesta 675SC at prime focus with 0.60FR Telescope: 8" F6 Orion Europa Newtonian Result focal ratio: F3.6 Exposure: combining 61x25s (gain 100%), 25xDF Seeing: lim.magnitude for naked eye 4.5, temperature -1°C, very soft fog Famous Horse Head Nebula (B33). Very difficult object for astrophotography. Hard processing had to be done to obtain the picture. The smaller picture, the better view - look here (25% image size):

IC434 - Nebula region, 11.11.2001 (01:06 UT) Resolution: 46.2 arcsec/pixel Camera: Vesta 675SC at photo tripod Objective: 2/50 Flexon Exposure: 30x5s (gain 100%), 25xDF Seeing: lim.magnitude for naked eye 4.5 The region with famous Horse Head Nebula (B33). However, much longer exposure is required for capturing it. Only a small hint of B33 is visible.
