Cheers Ernie.
Minolta to Olympus adapters are quite expensive. What I do in a situation like that is strip the teleconverter down and mount the lens assembly inside either the T-mount or inside a macro tube. That's one reason why I tend to stick to Pentax teleconverters as the adapters are really cheap and the teleconverters are very common compared to other makes.

Yes Paul I discovered that, but I have made up an adapter for the olympus side, just waiting for one to go from Minolta to T2, then I can try it , weather permitting that is.
I did try the two Barlows today, but the wind was fighting against me and it won as you can see from the image, even at Iso 800 the speed was only 1/30s, hence it's a bit soft. But I think it will work ok. Had a bird or two having a look at the berries, but they are still not quite ripe, but when they are I should have plenty of subject matter.
At one stage you where using extention tubes, but you seem to have gone away from that, was there a particular reason for it.
I am going to try your idea of taking the lens unit fron it's mount, and putting it into the barrel, I am planning a method of doing this at the moment, I am wanting to make evering thing more compact, and reducing some of the weight hanging of the back of the scope.
Last year I had some extended 1.25 barrels made, lookint to have the same in 2" Ernie
