1st attempt at the Moon (28th Oct 2015) using a Canon D700 & Tamron 70-200mm f/2.8
The magnification with this lens is rather poor for astrophotography. Here is the full frame at 200mm:
The image stabilisation really helps to focus the object and get a clear image. Due to the poor magnification the fine detail resolution is unfortunately limited by the number of pixels. The aperature on this lens is huge (f/2.8) so the ISO settings were quite low (200-400) when taking the first images. Higher than 800 on this camera starts to get very grainy.
