La massa mancante (chiamata poi materia oscura) fu proposta per spiegare la mancanza di massa dello spazio in relazione al valore di gravità.
Molto belle queste fotografie. ????
Saluti.

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
