I took the front lenses out to clean them and i think i put them back in the wrong order.Image is now blurry and will not come into focus.Need help putting it back properly.I need to know the lense configuration on a jason model311 constellation astronomical telescope F=700mm D60mmhow many combinations could there be, like 5?
just build and try until moon is in focus.I need to know the lense configuration on a jason model311 constellation astronomical telescope F=700mm D60mmWrite to Bushnell customer service either by mail or from their web site.
Be sure to give approximate age of scope, model, serial number and country of manufacture.
Another technique is to mark each lens element on one side of the edge with a felt tip marker.
If you have 3 elements, there are only sixteen combinations.
Be sure to make a chart showing what you have tried.
Use a far away object (a mile or further) for focus testing after each reassembly
