Astronomical Scenario
The fabled Equatorial Mount fairy hovers over your head, buzzing about trailing sparklies, and holding two of your favorite mounts, one in each hand: a Vixen GP-DX w/metal pier, and in the other, a GP-DX w/ash wood tripod. In her(or his, for those of you in California) characteristically high- pitched and squeaky voice, she asks... "Which one would you like?" You choose, whereupon it drops from the sky to the ground unscathed, and free of import duties. Which would you prefer, and why? Alan |

I stand guard and stay the course with my DOB mount. O! But you can't motorise a Dobsonian. Alan |

snip Hi Alan, The Vixen pier is extremely stable, but REALLY heavy once assembled, and cumbersome to move around indoors, especially if you care about your furniture. If you could set it up permanently, go for the pier. If you're looking for something that's transportable, take the wood tripod, which is still very much OK. FYI, I have both but I'm mostly using the tripod (still planning for a permanent pier setup sometime in the future). Jeroen. Hello Jeroen, I had sent back a complete Vixen setup, that is, their 4" achromat on the GP mount w/aluminum tripod, and at last I've been notified of its RA dispostion. Astronomics of Norman, Oklahoma charged me only a 5% restocking fee for their trouble, but perhaps only because I had just previously purchased from them a Takahashi FS-102 O.T.A. combined with the intent to exchange the return for just an equatorial mount to complement. I finally decided on the GP-DX w/ash tripod. I think it'll be great. I did consider the pier, but decided that it was not as versatile, though that doesn't mean I won't consider it in the future, of course. Alan |

Astronomical Scenario
You can too! I saw a 8in Dob at the RTMC back in 87 I think it was, where the
guy not only had wheels that drove the mount a full 360degs around, but the bearings had wheels that drove it up and down and all this was controled via an Atari 800XL with his own designed add on hardware and a 1050 Disk drive that held the data for the finding of stars. So don't go around telling anyone a Dob can't have control motors on it, I've seen it first hand. Someplace in my photos I have stashed away I have photos of the set up. -- "In this universe the night was falling,the shadows were lengthening towards an east that would not know another dawn. But elsewhere the stars were still young and the light of morning lingered: and along the path he once had followed, man would one day go again." Arthur C.
