Best at what it does

The MSM is the cornerstone of my lightweight wide field setup. As it transforms an ordinary camera/tripod setup into an astrophotography setup.
Really enjoy the MSM

Mathew Taylor (Phoenix, US)
Wedge for precise polar alignment

As is typical of all MSM products, this wedge is crafted of high quality materials and precisely machined. The altitide adjustment is very precise and easy to use. The azimuth adjustment is some what more limited. It allows precise positioning withis a somewhat narrow range - but you may need a tripod that allows column rotation or a small rotation table if you cannot position your tripod close enough to north to be within this limited range of adjustment. The altitudde lockdown clamp works - but the spring holding the screw may interfere with tightening. And the clamp level may need to be rotated to avoid physical confilcts with your other equipment. Overall a very well made high quality wedge. RECOMMENDED

amzing product

Great Tracker for my 50mm

Very easy to setup and polar align using the laser. I use it for my astromodified camera to capture wide field star fields at 50mm. The portable weight of it makes it easy to just keep it mounted on my tripod and quickly carry it out for some snapshots.

Another thing I use it for is livestacking. I point it at an area of the sky that I want to see, and watch the stars start to pop out on my phone. I use a third party device to connect to my camera and show the livestacking.

Nicely Built!

Well constructed and precise device.

Koutilya PNVR (College Park, US)
Polar Alignment got more precise!!

I was having trouble mounting the camera setup + MSM tracker on a ball head to do polar alignment. By the time I visually align the entire setup and tighten the ball head, the setup goes out of alignment. It gets extremely frustrating having to do this step over and over again in the field. This wedge completely changed my experience into a pleasant one. Such a precise polar alignment made possible an exposure time that reached close to 3 min for a 35mm lens without obtaining star trials in the image. I am very impressed with the comfort and results it brought me on the field. I highly recommend it!!
