This is the same Vixen Dovetail Plate Mounting Block that is originally supplied upon the Vixen Sphinx, GP2, and GPD2 mounts.  It is primarily offered as a replacement for a lost or damaged original dovetail plate mounting block.

However, if you own a Vixen Atlux mount and wish to use the Atlux mount with Vixen's standard #2661 dovetail tube plate or #2576 accessory plate, you will need to purchase this dovetail mounting block as well as Vixen's #8779 base plate for the Atlux mount.

The Vixen Slow Motion Handle attaches to the Great Polaris series mounts for fine manual slow motion control of the right ascension or declination axes.  Two are originally supplied with these mounts, and it is offered here as a replacement for a lost or damaged unit.

This is the same Vixen Counterweight Shaft that is originally supplied upon the Vixen Great Polaris, GP2, and GPD2 series mounts, and is offered as a replacement for your lost or damaged original counterweight shaft.

This Vixen 8.2 lb (3.7 kg) SX Counterweight is used to add stability to German-type equatorial mounts.  While your standard counterweight might be sufficient for observing at 45° of declination, when you're at or near zenith it might be a different story.  The same is true as you add various accessories such as cameras and off axis guiders; these all add to the weight upon the scope's mount, which in turn necessitates additional counterweights.  It is a good idea to have enough counterweights on the mount to handle the scope easily at zenith, and then when you're at more middle declinations you simply move the weights up towards the neck of the mount.

The Vixen STARBOOK-S is a spiffy complement for Vixen GP2, GPD2, and older Great Polaris series equatorial mounts.  It incorporates a "GO-TO" controller with a built-in star chart that quickly indicates where the telescope is pointed upon its 2.6" monochrome LCD screen.  The STARBOOK-S is equipped with upgradeable software containing a 22,000-object database, giving the user a large variety of heavenly bodies to observe that even includes comets!  Through its LAN port and an internet connection, you can always hook up to the Vixen website and add the latest information at any time.

The STARBOOK-S' drop down menu of different categories of celestial objects (stars, planets, Messier objects, NGC objects, etc.) only displays objects that are available to be viewed at the specific time you're observing-eliminating entirely unnecessary frustration produced by other "GO-TO" systems which don't let users know that selected objects are currently below the horizon.  With Vixen's STARBOOK-S, your time's spent viewing, instead of endlessly searching.

Out of the box you'll need 4 "AA" and 8 "D" batteries to operate the Starbook-S.  Though the controller's "AA" batteries yield 8 hours and are easily found in rechargeable format, the "D" batteries for the included motor drive battery box don't give you much more than a night's observing power.  Most users end up using either the #3599 AC adapter or the #8643 Cigarette Lighter Adapter with a Celestron Power Tank instead of the "D" battery box.

The Vixen Optics HAL130-GP is a full size, stable and sturdy aluminum tripod intended for the GP2, GPD2, and all older Vixen Great Polaris series telescope mounts.

The HAL130-GP has height adjustment from 31.9-51.1" (81-130cm) and weighs just over 12 pounds (5.5kg), so it isn't terribly difficult to transport.  If you need additional height to accommodate your blessed stature or the use of a long refractor scope, add the optional #3909 Half Pillar.
