Wow those are fantastic pictures. What kind of equipment do you need to take those shots?

Hello Dor,
Thank you. Basically you need a telescope or a telephoto lens, and ideally a mount that can track the rotation of the stars and a camera. You can take quite detailed pictures of the moon with a 300mm lens and an SLR camera on fixed tripod, but for faint deepsky objects such as galaxies and nebulae you need long exposures (minutes) so you need a motorised mount that compensates for the Earth's rotation. For small objects you need a lot of magnification, so the tracking of the stars becomes more difficult due to inaccuracies in the drive mechanics. You can spend $$$, just for a high quality mount! It's all very addictive though.
Cheers
Greg
