6" Eagle Adjustable Folding Pier (EAGLE6)

For use with the Mach1GTO German Equatorial Mount as well as the Astro-Physics 400, 600 and 600E Series Mounts produced previously.

The new Astro-Physics 6" Eagle Adjustable Folding Pier is a versatile work-of-art as well as a totally practical tool for the advanced imager. The one piece assembly sets up quickly in the field and allows adjustment of pier height, leveling of the mount, and eases the process of polar alignment.

The practical height range of the pier is 24" to 36". Adjustment is made by moving the center column tube up or down within the two inner ring assemblies and by moving the legs in toward the center. Adding the optional 8" extension piece that attaches to the top of the pier gives a total practical height of up to 44".


The 6" Eagle, folded and ready to go!

Versatility and Flexibility!

The 6" Eagle is a breeze to set up and adjust. The included carrying strap makes transport to and from your dark site easy. Large comfortable hand knobs make the whole process tool-free!

To set up or adjust, simply loosen the 3 Leg Adjustment Knobs to spread the legs apart or fold them in. Move the legs in and out from the 6" Eagle's center column to fine tune the pier's height and to level the assembly if the ground is uneven. Then, re-tighten the knobs. The 6" Eagle's feet articulate to adjust to the terrain.

To change the center column position, remove the 6 Pier Column Height Adjustment Knobs and simply slide the center column up or down to the desired position. Attachment points are in 4" increments. Re-insert the knobs, tighten and you're done. The 6" Eagle can be adjusted as follows:

  • Your mounting will have an additional 30 degrees of azimuth adjustment in the Pier Adapter Slots. This will greatly speed up rough polar alignment!
  • Pier leg uneven ground adjustment range: 4" over a 36" distance, or 6.5 degrees of slope (while maintaining a minimum distance of 18" from the center of the pier to each foot)
  • Pier leg maximum extension range: 48" diameter circle (maximum stability - see illustration below)
  • Pier leg minimum recomended extension range: 36" diameter circle (minimum stability - see illustration below)
  • Pier height min: 24"
  • Pier height max: 36" (with legs brought in to 36" diameter circle)
  • Pier height max with 6" Eagle extension (sold separately): 44"
  • Pier measurements folded: 12" diameter x 32" length
  • Pier weight: 28 lbs. (12.7 kg)

Accessories for your 6" Eagle Adjustable Folding Pier - COMING SOON!
Of course, this brilliant package wouldn't be complete without the little extras that allow you to customize the 6" Eagle for your own special needs and circumstances. We won't leave you out in the dark (OK, actually we will!!) when it comes to accessories either. We should have our accessory package ready for sale some time in late January or early February, 2007. In characteristic Astro-Physics fashion, we have tried to make the accessories as versatile as possible. They will not only fit on your new 6" Eagle, but they will also fit on the Adjustable Wood Tripod (AWT000), the Lightweight Adjustable Aluminum Tripod (SDS400) and some sizes of the 6" Portable Piers. The first member of the accessory line is available below: the 6" Eagle's 8" Pier Extension:

8" Extension for 6" Eagle Pier (EAGLE6E8)

This beautifully machined extension for your 6" Eagle Adjustable Folding Pier provides an additional 8 inches in height to your versatile pier. Each extension is made from a single piece of thick walled aluminum with an overall length of 8 15/16". The extension is extremely rigid and will not compromise the stability of the 6" Eagle Adjustable Folding Pier.

The richly black anodized extension features 3 slots at the top for attaching the pier adapter of the Mach1GTO or of the 400, 600 or 600E series mounts. By including drilled and tapped holes every 60 degrees around the extension's base, the extension allows positioning of all 3 mountings with one of the pier's legs pointing toward or away from your respective pole according to your personal preference.


With the 6" Eagle Pier Extension, it is possible to achieve a pier height of 44 inches with the legs brought in to a 36" circle footprint. The picture at right shows the pier set at 40" with the legs set wide.

Note: A second extension can be added, but we recommend that you only do so with the legs fully extended to their 48" circle footprint (net gain is 4"), and that you not balance a large (especially a long) instrument on top.

Dimensions: 8 15/16" overall length; 8" extension length; 6 3/16" diameter.
Weight: 3 lbs. (1.4 kg)
