Product Information


In order for any star tracker to work the way it's designed, polar alignment has to be done in the first place. It is the act of aligning the rotation axis of a star tracker in parallel with Earth's self-spin axis. How do you know when your Move Shoot Move Star Tracker's rotation axis is aligned? Well, the Polar Scope we have here does just that!

Polar Scope A Package

If you only have a MSM Star Tracker, which means you don't have a Pointer, a polar scope mount or a polar scope illuminator, this is the go-to package for you. It includes all the accessories needed to do polar alignment on a MSM Star Tracker:
  • Polar Scope A
  • Universal Mount Combo
  • Fluorescent illuminator 

Polar Scope B Package

Similar to Polar Scope A Package. Included are:
  • Polar Scope B
  • Mount For Polar Scope B (without hot shoe adapter)
  • Fluorescent illuminator 

How to use Fluorescent illuminator?

Please use your headlamp or phone light to shine the light first, the paper inside will absorb the light and then glow in the dark. If you want to test it before going out, please test it in a dark room.

This is the example of the lightened image of polar scope A

    Cnc machined illuminator. horrible design

    This product is definitely a step up from the shitty wire illuminator that came with the scope. However it would have been 20 x better if it was a button. Why would it be a twist mechanism? Only a child with tiny fingers would be able to operate it effectively. In the cold? Forget about it. Really needs to be changed to a button. Seriously. Easy fix. Fix it.

    Polar Scope Illuminator

    Bought the polar Scope Illuminator in the hope the device would illuminate polar field. After a few adjustments the product worked as advertised.

    Easy alignment, could use clearer instructions

    I recently added the polar alignment scope to my Move Shoot Move kit, in order to get a better polar alignment than is possible with the laser. I also bought the 90 degree elbow adapter so that I wouldn't need to crouch awkwardly while getting my alignment right.

    Once I figured out how to mount the polar alignment scope and rotate the reticle to the correct position, polar alignment was simple. Clearer instructions would have been helpful here. With this said, the MSM community is very supportive and helpful, should you have questions.

    I would have loved to know:
    * Should I get version 'A' or 'B' of the kit? I chose A and it worked, but it was not clear which was best for me?
    * How do I properly mount the scope into the mounting bracket? The scope clamps in nicely but I wasn't sure I'd positioned it properly, or pushed it far enough in to the bracket. A picture or two would have helped.
    * How do I rotate the reticle to match my polar alignment app? I figured this out i the end, but it took a bit of guesswork.

    Having said that, once I had this figured out, my resulting alignment was very good - much better than I achieved with the laser.

    One other recommendation - if you have a choice between the 3D printed plastic LED illuminator or a machined metal one, pay extra for metal. It's much more durable, should you accidentally drop the alignment scope (ask me how I know).

    All in all, I highly recommend the polar alignment scope.

    Very good Polar scope

    I bought the polar scxope and its light as a replacement for a previous model. I found myself very well and the light illuminates the reticule very well. I can only recommend the product.

    Great product to make it a complete package

    Polar scope and illuminator are great for completing the package. I’d recommend MSM make their own detailed videos on calibration and the many ways if setting up the MSM system. Relying on user YouTube is okay but things like how tight you can tighten a ball head or the science for using the Z bracket from MSM would be great.

    cloudy skies

    havent seen a blue or black sky since i purchased the polarscope, its our winter here in south australia at the moment. this year i thought id get into astro alittle more seriously and why i bought the MSM tracker. cant wait for the weather to clear in the coming month or so to get out and get some great shots. thanks, terry

    Not so easy...

    At the moment, it is probably one of the most easier and affordable kit to track stars, but it needs patience and hours of practice to get some results. Instructions are only available in English, and it would be easier if they were also in other language like French. Also, online, it could be great to have some pictures and when we select one, we have the process to get a similar result. Thanks.

    Polar scope A

    Easier touse than I thought!! It should come with the 99 degree prism to make it easier to use.
    But a great product!!!
