After trying to be a contortionist looking through the polar scope I decided it was time to do something about it. Brilliant piece of kit, will save my knees and neck when polar aligning. Thanks FLO.

Much as other reviews have said the 90 degree works fine and does the job, It has a click locking mechanism so you can rotate 360 degrees (around the optical axis of the eyepiece) and it will lock into place at or near your preferred angle of viewing. The only limitation for me is that the field of view using the supplied 'Astro Essentials Polar Scope to Right Angled Viewfinder Adapter' even on the 1x (widest) setting is limited to about half the full FOV of the polar scope on my EQ5 mount. Have yet to test it in the field so can't yet say if this is a significant issue. Just worth mentioning as 'your mileage may vary'. A plus, is that the unit also comes with many camera viewfinder adapters (plastic) so one can use it for doing copy stand work or low-level macro shots for example.

Bought this to solve an issue polar aligning my EQ-5 - bending down to see Polaris meant getting into positions I couldn’t hold for long - this works brilliantly! I can get away with hour having to half crouch, and it works a charm when allied with the polar illuminator and the PS Align app. It comes with a plethora of adaptors so can also be used with possibly every dslr available!

I had slight reservations about this product given the mixed reviews (of this and the Skywatcher equivalent) but these have been completely allayed. It works perfectly on my EQ5 and EQ3 polar scopes. Drooping issue mentioned elsewhere appears to me to be related to not putting the adapter fully home on the body of the polarscope. If you try to fix it to the outer focusing ring of the polar scope it definitely droops - this problem disappears when the adapter is pushed all the way home before tightening. "Budget" optics are more than bright enough to facilitate clear views of Polaris and the reticule. All in all really pleased with my purchase.

This piece of kit works just fine. Fits over my polar scope and saves me having the kneel down. So I am very happy with that. Plus the x2 zoom is very useful to spot what actually is happening!

The way this eyepiece fits to your polar scope is it just slips over and you tighten a single screw that in turn tightens a collar. This works fine, but does pull the alignment reticle out of the center of the view. I knew this at time of purchase and wasn't put off. To fix the issue, I have wrapped a few turns of PTFE tape around my polar scope and now the eyepiece fits over snug and only a few turns of the screw is needed to lock it in place. Minor issue solved! (Along with duck tape, PTFE tape solves loads of problems).

It's certainly a useful bit of kit for an old codger like me where bending down to look through a polar alignment scope brings its own particular challenges. It comes with viewfinder brackets that very usefully mean I can also attach this to a number of DSLRs. that plus the 2x magnification switch should prove useful in acheiving sharp focus. The only real drawback I've come up against is that if you leave it attached to your mount indoors in my case an EQ35 then take it out you'll find yourself hammerd by condensation which forms annoyingly throughout the unit so either pre-cool it to outside temperature or just pop it on when needed. Promptly supplied as ever by FLO.

Due to a 'who's buying what' present confusion, I ended up with both this and the Skywatcher equivalent.
Which allowed me to perform a side by side comparison on my SW EQ5Pro.
Firstly, despite what has been written here previously, they both fit snugly and well, with no drooping or any concerns about reattaching to the polar scope.
The only difference being the Skywatcher uses three plastic tipped screws at 120' around the adaptor and the Astro Essentials uses a brass tighten ring with a one screw movement.
Of the two the Astro Essentials is probably the better method, only one screw to tighten and doesn't mark the polar scope.
The quality of both the eyepiece and the adaptor is better in the Skywatcher, the Skywatcher eyepiece is noticably heavier, the quality of the optics looked the same but I was only able to do this in daylight so you may see a difference in the dark.
In conclusion, the Skywatcher is better quality but more expensive but I think the Astro Essentials has a better fixing method and it does the same job.

This has meant I can polar align more accurately without discomfort. Bright image and fits well without issues . Mine does fit securely - I have left it in place as unsure how it would cope with regular removal and re-attachment .

This right angled view finder works perfectly on my Star-Adventurer! Was surprised to find an assortment of pieces to adapt it to various brands of cameras view finders included with it.

What a great piece of equipment. No more kneeling down to align the polar scope on my star adventurer. Easy to fit and take off once alignment is done. Great service from FLO as always. Maybe though they can change the sticker on boxes from may contain clouds/snow to may contain clear skies as actually getting outside to use my telescope and tracker more than once a month would be nice
