Wonderful New Mount from Synta
Updated 31st January 2013

Fig 1.) A superb telescope (the Synta  190mm MAKSUTOV-NEWTONIAN riding on a sleek new multi-purpose heavy duty mount from Synta .


Fig 2.): The new AZEQ6 GT goto mount from Synta is set up for equatorial use. While it also can be used as an heavy duty dual telescope mount it boasts many new and well thought out features. AstroShop have worked closely with Synta for a long time, with product development (particularly for use in the southern hemisphere) and is proud to provide this first hand / first look at what maybe the only mount you'll ever need. In fact during our testing the manual was still being written.

Arriving in two large cartons (one for the tripod and counterweights and the other containing the mount head, controller, pucks etc) this system is packed very securely for shipping with foam lined inner carton and an outer carton. The new mount head casting looks fantastic in classic white powder coat finish, large clamping knobs and highly polished and chrome fixtures. Opening the side panel reveals the new belt drive system on both axis.

Fig 3.) The main panel. Note the new two pin, screw on polarised power connector, and SNAP camera control connector. The hand control interface is now like the HEQ5 mounts sporting RJ45 connector rather than the old 9-pin RS-232 connector.

Fig 4.) RA clamping lever (black handle) sits back where the polar scope is fitted. Nice chunky elevation bolt lever makes for easy adjustment.

Fig 5.)
Solid chrome elevation lever noted at rear and just behind it the R.A clamp lever. At the top of the counterweight shaft is the three pronged dec clamp. Seen here branded as Sky-Watcher, it is also available branded as Saxon.

Fig 6.) Side plate removed reveals the new belt driven encoder drive motors that yield a quieter, smoother and more accurate slewing motion.


As an Equatorial mount
While there is a great deal I need to test yet including side by side telescope operation in ALT-AZ use, for initial testing I set up the mount in equatorial mode and placed the mount in rough polar aligned position. Adjusting the latitude elevation was a breeze using the solid silky smooth lever seen at the rear of the mount head (fig 4) above.  After balancing the scope and applying power, the SynScan V3 (fitted with product specific V3.31 firmware) did not give the usual initialisation beep EQ6 users are familiar with. It first prompts for the mode you wish to use. From the choice of EQ or ALT-AZ, after selecting equatorial, it then gives that nice comforting beep. Setting up is the same for date, time, location, daylight savings and number of alignment stars you wish to align to. I selected a simple two star align using Achernar and Altair. The first thing that really impressed was the smooth sound of the motors when slewing at full speed. A little like a muffled dentists drill - not offensive by any means due to the new belt driven steppers with encoder and was about as audible as a HEQ5 yet completely different sounding to the gears in motion of classic NEQ6. While I am on the subject, after an alignment is completed, one can manually move the mount to another position in the sky and clamp off each axis again without losing alignment.

Selecting a few  common favourites from the Synscan tour selections, it was off to M6 then the colourful double Alberio. Both fell perfectly in the centre of the 22mm eyepiece. Later I was off to M7 for a check and then across to NGC104 (47 Tuc) globular cluster. I left it for 30 minutes and came back to the eyepiece to find this magnificent cluster still centred nicely in the eyepiece. I decided to then try the lovely Pavo globular cluster (NGC6752) and it too fell nicely into the centre of the FOV. Off to one of the wandering worlds, Uranus this time. It wasn't centred but I could see it within the field of the eyepiece. As the clouds started building up, I quickly shot over to M8 now a bit low in the west but centred in the view.

As an Alt-Azimuth mount

Fig 7.) So easy to convert to ALT-AZ configuration for one or two telescopes within 5 minutes. Use counterweights on the extendable declination shaft for balancing a single heavy scope or simply add another scope and extend for best balance of the system.

Another great advantage of mounting your optical tube or tubes on this type of mount is that you can use a CCD camera fitted at the back of your telescope and point overhead without the worry of it banging into the base like of conventional old fork alt-az configurations like Celestron CPC and Meade etc...). Setup is easy just like the "go to" collapsible Sky-Watcher Newtonians. Simply set the mount level and facing north, power up and select ALT-AZ mode from the start up menu in the hand controller. After setting your location, time, date and Daylight savings (yes/no) options as usual, the user is presented with one or two star alignment options. I always prefer 2 stars (recommended). You must manually slew the mount to the first star chosen from the star selection options setting up as follows:

1) With the control panel of mount facing to you, the telescope should be installed on your right hand side.
2) When the telescope is levelled (ALT= 0 degree), the telescope should point forward with the control panel of the mount still facing to you.
3) To align the first (or the brightest) alignment star in AZ mode, always rotate the mount in azimuth (the RA axis) first to the right in the direction of the alignment star and then rotate the altitude (declination axis) upwards to point to the star. The telescope should not rotate or flip beyond 90 degrees overhead (zenith) to point to the first star otherwise it will cause problems when slewing to the second alignment star.

Once the first star is centred, and then selecting the 2nd alignment star, the mount will slew itself to or very near to that star (close enough as seen in the finder scope). Once you do a manual centre in the finder scope cross hairs and then at the eyepiece, simply press enter and you're ready to tour the night sky.

When objects are not perfectly centred, the ALT-AZ mode also allows the user to re-centre on the target after manual re-centring is done with direction keys by simply holding down the ESC key for improved accuracy (just like in equatorial mode use). The extra mounting head puck provided with the unit for side by side telescope use has fine altitude adjust lever screws for helping with on-axis alignment with the main scope. And of course when it comes to sharing the load between a heavier primary scope with a much lighter smaller one on the opposite side, one can simply extend the declination shaft in or out to suit.

**Latest testing reveals some inaccuracies in selected target centring using ALT-AZ configuration after doing a 2 star alignment but we have reported this and future firmware updates for the SynScan controller will no doubt sort the issue.

***UPDATE 12th December 2012 - As anticipated, feedback and quick development response has led to the required updates. See link at the bottom of this article.
