Super Takumar 200/4: 2x 2x teleconverters

This is taken at f5.6 and with 2 2x Vivitar teleconverters on the lens. The extra reach is nice ( I think that makes the lens a 1200mm equivalent)

Pentax crop of 1.5 x 200 x2 x2 .

 Unfortunately the adding of the extra glass makes the moon not as crisp as i would have liked :(

ISO 1600 F5.6 1/400th of a second
