Just got a Pentax ME Super in eBay and two lenses from a friend of mine.
One of the two is a 200mm Shacht prime.
I have also won on eBay, 10 minutes ago, a x3 teleconverter and I was thinking if I add a second TC how good would the results be.
I know that everything will become darker, but it's also true that a full moon is super bright.... And if it's too dark I can also go with higher ASA film.
I considered also that a mirror lens of such focal length would be at least f/8, but would be really difficult to justify to the wife. (aaah!)
I was thinking at another x3, having a 1800mm lens to shoot at the moon should be quite a blast...
I know it may well be a simplistic view, but I wouldn't mind trying... Is it really worth it or am I planning in actual fact to throw in the bin £6?
