Great review Jeremy! You have deftly described an experience appreciated by those of us who have wandered into this "new" realm of visual observing. Double vision rekindles the excitement of being a "newbie" all over again so vastly different as it is. I enjoyed my first double vision views at a star party and was smitten immediately! I shortly thereafter became the happy owner of a set of Denk II's and D21mm EP's. Beware of the bug, and be sure not to gaze upon any of your favorites with this technology or you too will certainly succumb to "Nirvana"!<br> <br>Monty Shindler
