October 03, 2003. A "different" Andromeda. It is a mosaic of 2 series, one 6x20sec near the core and one 20x30sec in the "rings". I forgot to shoot dark frames, so a few hot pixels can be seen, but still the amount of structure in the galaxy is rather interesting. The foreground stars are Milky Way stars. I used my C8 with Vesta SC3 b/w and a 0.6x Mogg adapter.

All images below were shot with my old Vesta 675K SC1 camera (uncooled).

M31, The Andromeda galaxy, 26. October 2002. My first galaxy ever. Due to the size of the galaxy, I used an SLR lens mounted piggyback on the mount. Camera: Vesta 675K SC1.
