Small overall dimensions

With the same M-zero standard version smart and compact design, the M-zero obs comes with very small overall dimensions (72 x 64 x 60 cm), in this way it is possible to place the full equipment in a very small observatory.

The M-zero obs comes already provided with the HQ stepper motors, as well as the M-zero HQ, to achieve the best performance possible in tracking.

The well known M-zero reliability and versatility allow to equip on the mount many different setup, double telescope setup included.

No Meridian Flip

The M-zero obs, as well as the M-zero standard version and the M-uno, allow the very helpful No Meridian flip feature.
Two main configuration: one telescope setup, double telescope setup

Among the many setup possible with the M-zero obs, there are two main configuration: the one telescope setup and the double telescope setup. The first one is more suggested for those who wish to use the mount inside an observatory, the second is suggested as a portable setup.

One telescope setup (better for small observatory)

This configurations is suitable for a small customized observatory, the StarGo board can be assembled on the bottom side of the DEC arm, in this way it can be also considered as an "extra counterweight". In this way, with small refractor, the mount can be also balanced without any counterweight. The telescope can track all night long, without the need of the Meridian Flip, without any collision risk.

Double telescope setup (optimized for portable/stable backyard configuration)

The double telescope configuration has been optimized for the portable setup or a stable backyard configuration
In this way it will be possible to fully use the second telescope.
Thanks to the high quality materials (anodised aluminium and stainless steel), the mount can be left outside for long time, by using a simple cover, to prevent rain/humidity/weather damage.
In this way it will be possible to have several sessions and, thanks to the PARK/UNPARK StarGo GoTo System feature.
With this configuration the StarGo board can be assembled directly on the pier, in this way any second telescope collision risk will be prevented.

Optional Motorized Polar Alignment

The optional Motorized Polar Alignment allow a full remote control, in this way, once the setup has been done, it will be possible to perform an accurate remote Polar Alignment.

NOTE: Motorized Polar Alignment are optional and must be purchased separately.
