Altair Astro TMS Universal Mount


Recommended Posts

I'll comeback and add some pictures to this, because the it is a thing of functional beauty!  I thought I'd just record some initial thoughts.  Oddly this is one of those bits you'd think would be hard to get excited about, after all it's just a mounting device...

My EQ is of the vintage that had only the Vixen style puck.  Having just acquired a new scope with a Losmandy bar I needed come up with a method of dealing with both styles of dovetail. 

 

Out of the box you find a precision machined lump of metal - it has that polished and precise style that comes with CNC fashioned equipment.  It has considerable bulk and is pleasantly weighty. I won't call it heavy.  The Altair logo is etched into it in a very cool way.

I needed a new puck to mount it. Again this has the same fit and finish. It screws to the bottom of the mounting plate with 4 screws.

Fitting is easy, undo 3 grub screws on the mount, pop it in place and replace the grub screws. Take care so it's lined up properly.

 

Operationally it works very well, scope can be tilted in rather than slid in. I think this is important as it feels like the scope is a lot more supported.

 

The bolts are smooth and tighten securely. They can sometimes snag if you tighten or loosen one side faster than the other, but this is just a practice thing

 

All in all it does what it should do. I feel much more secure with my kit attached to it than I did the original puck.  It's also massively improved the look of my mount, which brings no practical benefit, but still make me happy.

I probably have the same vintage of EQ6 as yours. Mine was bought in 2006, and has served me well, but the old girl needs a makeover. I upgraded the mount last year with the EQ6 belt mod, which made a great improvement in guiding, and reduce noise while slewing. Soon I will be replacing the RA worm mount with an upgraded version from Rowan Astronomy. It's called the EQ6 & NEQ6 Zero Backlash Worm Mount. I have heard good reports about it halving the RMS in PHD2, and is a cheaper option than spending £2 or 3000 on a new mount. My guiding is not that bad considering, on a good night around 0.5-0.6 RMS, but any improvement is a big bonus for me.
