Volcanic ash, sunset, moon, venus and mercury

The sunset on April 16th was clearly affected by volcanic ashes in the south of London, UK.
The sunset was unusually hazy and dusty, most likely due to the volcano that erupted in Iceland a few days before and which ash plume disrupted air-traffic over northern Europe. The second picture shows an early Moon in conjunction with Venus and a very dim mercury

I took the picture from the loft of my house, using a canon eos 500d and an 18-200mm tamron lens set at 200mm for the sunset and at 25mm for the conjunction.
