I don't have a favourite star, rather a nebula; I'm sure you'll guess, it's the Horsehead Nebula. Although recently I've started seeing the Triffid Nebula; don't tell Horsey! Shhhh :-)
By the way; do you know @clodoweg? You should meet, he takes some really nice astrophotography from his back garden with his telescope and camera. You should meet :-)
