嗨朋友們！感謝 MSM 的用戶 Gerry Mulligan，他在 Move Shoot Move Facebook 用户群組里指出 彎腰查看極軸鏡內部分劃板的不便，這個問題對於很多天文攝影老手來說尤其突出。我們團隊在收到這個反饋立刻研究解決方案， 感謝提出這個問題的用戶Gerry。 因為有他的反饋， MSM 才會推出配合極軸鏡使用的直角取景器！
這款直角取景器以更符合人體工學的設計，輔助您查看極軸鏡內部分劃板。安裝後的取景器會與極軸鏡呈 90 度角，這樣您無需彎腰就可查看極軸鏡內部分劃板。同時直角器的目鏡可以旋轉 360 度。
- 1倍 和 2倍 可切換放大倍率
- MSM 極軸鏡 A
- MSM 極軸鏡 B
極軸鏡目鏡直徑介於 27.3mm 和 30.3mm 之間

Right Angle Viewfinder for Polar Scope
The MSM is great if one use it in the way that it was designed for (wide angle astrophotography). You can get outstanding results when used like that.
Pros: Lightweight, compact, easy and fast assembly, user friendly.
Cons: The Laser and Polar Scope need to be calibrated by the costumer (a relatively easy process, but that shouldn't have to be done when you buy something new. It's the only reason why I don't give it 5 stars).
Newbies beware: If you're using a double ball head set up this thing is an absolute nightmare since the view is flipped: up is down, down is up, left is right and right is left. Get a geared tripod head and the polar alignment will be immensely easier once you get the hang of it. I would highly recommend laser aligning to get close then using this as fine tuning. As for the hardware: The polar scope itself is adequate for use on the MSM but the unit that mounts the scope to the rotator is poorly designed as it is only possible to lock the scope down into one of the 3 different diameter bores with one small plastic screw. This can cause minor variations in the mounting angle which can throw the polar alignment off slightly. I was able to overcome this engineering flaw (I'd be willing to bet the engineers were overridden by the accountants that wanted the old one unit will sort of work for all) by making my own mounting bracket in a machine shop using one precision size bore and 3 threaded holes for the locking screws thus improving repeatability. I also made one for my laser pointer. Not everyone has that luxury. The plastic adapter that connects the polar scope to the right angle viewfinder necessarily covers the reticle focus ring so if you are not in focus prior to assembly you have to take the adapter off and focus the reticle. This really isn't much of a problem but it sure would have been nice if that focus ring also had a locking ring to prevent losing focus, maybe I'll make one of those also.
All in all this is an OK product that could be easily improved without much effort on MSM's part: stock mounts with single bores in three sizes. Hopefully they will take heed. I purchased it to eliminate the awkward positions required to align with a polar scope on a setup that is relatively low to the ground which I prefer given the improvement in overall stability in the lowest possible mount position. In that respect it has proven to be helpful.
Very useful so I don’t have to crank my neck to view. I don’t have a egrets neck.
Well made, arrived quickly and makes setup much easier.
The right-angle finder is a great addition to the MSM system. It makes it much more convenient to use the polar scope, and not hurt your back.
Excellent wee bit of kit
Nice accessory for the polar scope. Fits great, helps make the polar scope easier to use.
It help to align even I can see Polaris.
Works well, has plenty of adapters to connect to various camera brands. The adapter to connect the polar scope to the right angle is solid and holds firmly. The right angle itself does feel light but does seem to hold up and holds focus, for its intended purpose I believe it's fine however I would recommend handling with care. Seems fairly priced compared to other competitors.
