Total lunar eclipse of 2011 June 15
On 2011 June 15 a total lunar eclipse took place. This eclipse is with magnitude 1.70 the deepest since 2000 July 16. The weather on that day was not good, cloudy (mostly overcast) with showers. But around sunset it completely cleared up. So we (a fellow amateur astronomer and me) found a nice location in Rheden Netherlands with a completely free horizon in the southeast. My friend used a Vixen 80mm Fluorite with Canon EOS 300 attached to it and I used a 40d with a Tamron 18-250mm and took the pictures with ISO 400, most I used 3-4 sec exposure time @ f/5.6 during totality and down to 1-2 sec f/8 while the Moon left the shadow. As my camera does not support multiple exposures (like my old T90 did), the photos with more 'moons' on it are 'photoshopped' by using one image as base and pasting the 'moons' from the other shots over it, optionally correcting color balance of the 'moon' image.
Th sharpness of the Tamron is not very good at full zoom in (250mm), even stopped down to f/8 the sharpness on the edges is rather poor. So I regret I did not bring my telescope as this provides sharper images.
At the end of the session I made a time exposure of the scene (there was a CFL lamp post 20 meters behind me) hence the brownish light. I took this picture at ISO 3200 and pushed it three stops to ISO 25000 to get a reasonable without too much grain.
