ADM Max HD Alt-Az Guidescope Aiming Device
The Max HD Alt-Az Guidescope Aiming Device by ADM:
This wonderfully useful new device is a highly practical innovation in the field. Allowing you to aim a guidescope or a long telephoto lens separately from the main scope, without the use of the three-point mounting rings, this fascinating contraption makes things a lot easier. It's so useful because often you can find yourself wanting to frame a particular field such as the Virgo Cluster of Galaxies with, for an example, a 300 mm lens- but chances are, you'll have trouble finding a guide star in the exact center of the field.
Now, with a wide angle lens, you could just put it on a ball head, find a guide star in the guidescope, and then aim the camera to frame the field.. But you can't really do that with long, heavy telephotos or short wide field refractors; their too heavy for a ball head. Usually, they would be mounted onto a flat plate with a tripod collar or Vixen dovetail foot that comes with many small refractors. The issue with that is simple; you can't aim them separately from your main scope, which you will most likely be using as a guidescope- and that's where the Max Guider comes in handy. You see, rather than the traditional setup for a mount, this device has a combo Vixen and Losmandy D female dovetail mount for your small refractor. Or, you could mount a lens on a Vixen Dovetail bar. Then the Max Guider allows you to move the scope and aim it in altitude and azimuth. The Max Guider has 20-degrees of movement in Azimuth, and roughly 7-degrees of movement in altitude. The Max Guider can mount onto a Losmandy D-style dovetail plate that would sit on top of the rings that hold your main scope. You can then easily remove it to use other accessories.
To use this device to image with a small piggyback refractor or a telephoto, you would acquire the field you want to shoot, before moving the mount and guidescope to an appropriate guide star nearby. Then adjust the altitude and azimuth on the Max Guider to perfectly frame the field to your satisfaction, and you are good as gold! Likewise, if you wanted to use this same device with a small refractor and a vixen style dovetail foot on top of a larger imaging scope, you would merely acquire the object in the main imaging scope, then move the Max Guider and the guidescope to a convenient guide star. All in all, the Max Guider acts as a far easier and more efficient to use alternative to Three-point rings, serving the same purpose far more efficiently!
