All I want is the barlow lens itself so that I can screw it into a diagonal. Looking for a total of three.
As with the previous request for 25mm plossls, I want to provide a functional way of using a diagonal with the Galileoscope kits I hope to make up with young interested astronomers.
The photos show the type of barlow - where I can unscrew the barlow lens itself and screw it into the diagonal.
In fact, you can keep the rest of the barlow as a little 1.25" extension tube
Again, for the cost of postage? or a few dollars if you want.
