Hello Joe and welcome to APUG. The View II is a great camera, espescialy if it has the Grafloc back on it. Anyway, any lens that you could mount and focus can be used. For time exposure with slow film, you could just uncap and cap the lens for exposures. Regarding the lens you have, try focusing it like if you were to use a magnifing glass to start a fire. You could measure the distance of the glass to the image when focusing on the sun and would know the bellows draw needed to focus at infinity.

You could also check it indoors by focusing an image of say a lamp at one end of the room onto a wall and see how far away the film would have to be.

It may be to large for the format but that is just a wild guess. Good Luck.
