SVBONYSV225 Alt-Azimuth Mount, CNC Hollow Aluminum Structure, Telescope Alt-Azimuth Mount with Fine Adjustment Shift, Variable Speed Gear, Black

Excelente cabeza de montura AZ. Firme y estable y fácil de utilizar. Lo utilizo con un tubo de 102 mm y distancia focal de 1,000 mm. Lo utilizo con un tripié Skywatcher.

Smooth with no slop or play cant believe how the built quality is unreal thanks Svbony 90mm and 102mm

Robust product. I even mounted my 21 lb Newtonian and it was very stable, though I plan to use it mostly with my refractors.

I am very impressed and happy with all the Svbony products I have purchased. This mount is no exception. I wish I would have bought it when it first came out.Having owned several manual altitude/azimuth mounts (i.e., ES, Universal, iOptron, Vixen Porta I & II, and mini Porta), this mount is ideal if you want a lightweight, portable mount that can handle up to 10 kg.Likes include quality versus price point-$160 +10% off—a great bargain. The mount head is easy to store and transport.The design is well-made, and the casting and finish are perfect. The mount head is painted off-white, and the paint is thick and smooth, and the slow-motion controls are buttery smooth with minimal backlash. The ability to lock both the altitude and azimuth axes is a plus. It will handle a 4-inch refractor (<f/7.5), 4-inch MAKs, and 5-inch SCTs if under 10 kg, I would limit it to no more than 7 kg.Dislikes: Excessive play in the azimuth bearing on my sample. The telescope wobbled when rotating in azimuth. It was partially mitigated by locking the azimuth and using the slow-motion controls. However, this is not acceptable. I removed the base plate and cinched up the 10 mm locknut on the azimuth, removing 95% of the play. From this experience, I learned that the mount is entirely serviceable. You must provide a tripod with a 3/8-16 treaded mount base. A weak tripod is the leading cause of instability.The lock and safety knobs on the altitude dove plate are poor. There is no need for two safety knobs when only one is needed. There is not enough room to optimally locate all three knobs. To make matters worse, the safety knobs on each end of the plate are taller than the large center lock knob, making it difficult to finger access the center knob. Also, the female threads on the dove plate are sloppy, causing the screws to wiggle when tightening. They do function, however.One last minor complaint is the altitude fiducial scale reads from 0 to 360 degrees, making it hard to set the mount in altitude (assuming you wish to locate objects using alt-azimuth angles). The altitude scale. should be measured from +\- 0 to 90 degrees.In summary, I look forward to spending more time with this mount. I highly recommend it.

Great Product!!!Some assembly required - the base needs to be reversed due to how the item is packed.Best to consult You Tube for instructional assembly videos.
