It really takes quite some time, patience and effort to learn these things and thank you for stopping by and reading my post. The camera I use is a NIkon D90, for the lens when taking pictures of the sky I use the Nikon AF-S DX Nikkor 18-105mm f/3.5-5.6G ED VR and for close ups I use the Nikon AF-S DX Nikkor 55-200mm 1:4-5.6G ED
