Does the job perfectly on my Star Adventurer 2i polar scope. No more getting down on my knees to polar align. The extra adapters are a very useful addition, and I have used the camera adapter for my Pentax DSLR, and it too works well. As always, excellent service from FLO.

Not bad, it’ll save having a cricked neck and wet knees. Comes with loads of camera viewfinder attachments as well. Does what it is meant to, with no frills.

This makes using my Star Adventurer 2i Pro, my HEQ-5 mount and my Explorer 150P-DS OTA so much easier to use. It saves me from a strained neck or back so allowing more comfortable polar alignment and longer viewingsessions. The 2x magnification means that I shall not need to buy a 9x50 finder scope for the 150P-DS and this device effectively changes my 6x30 to 12x30. I haven't tried the camera view-finder attachments as I my DSLR has a tiltable screen.

As usual, prompt and efficient service from FLO.

Got product super quick, awesome service, thank you

I struggled with the weight and needing to have my tripod fully extended to use my 8 inch newt and ancillaries, and still found it difficult to look through the polar scope. Having a Skywatcher Eq5 pro, I was not able to consider the ioptic polar aligner, which I would have liked, as it was not compatible. I bought this right angle adapter without realising what a game-changer it was! My tripod is unextended, enabling easier loading and a firmer footing, and the image is clear and magnified at a switch. Am delighted, and even got an adapter to use on my Canon 7D!

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).
