About this product

Model:  ae_ps_ra_vf

This useful right-angled eyepiece and adapter makes polar alignment much more comfortable.

The adapter has 30mm internal aperture so fits most Sky-Watcher, Celestron and Orion polar scopes and includes a non-marring brass compression ring for a secure fit without damaging your polar scope. 

The right angled eyepiece is easy to use and focuses with a simple twist. It can also be rotated 360º for the most comfortable viewing position and features a 1x or 2x zoom for precise polar alignment.

Folding rubber eyecup provides comfort and helps keep out stray light. 

Supplied in a soft case. 

Works great with Sky-Watcher Star Adventurers!

No more neck ache

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.

Right Angled Eyepiece for Polar Scopes

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

Received the Right Angled Eyepiece with adaptor, this product is utter garbage.

Firstly, the quality of the items are extremely poor and are typical of cheap Chinese products, in fact the same eyepiece is available on e-bay for half the cost you are charging.
Secondly, the adaptor does not align correctly with the eyepiece, it is off centre and does not give full view of the polar alignment, to correct requires removal of some of the adaptor material.
Thirdly, fitting the adaptor to the eyepiece was extremely tight, this has damaged the eyepiece retaining clip.
I wouldn't put this anywhere near my EQM-35 mount, never again.

Looks pretty much identical to the SkyWatcher unit with one exception, it only has one thumbscrew to its detriment. The unit kept drooping regardless as to how tight you do it up as it is on the side. Had the thumbscrew been on the top this would have pretty much stopped that from happening, or even better, use three thumbscrews like ths SkyWatcher unit, afterall, I expect that is why the SkyWatcher uses three to begin with! Shame really, I don't think it warrants the price either being only around £10 cheaper than the SkyWatcher unit, having said that, I don't think the SkyWatcher price is very good either for what it actually is. I returned mine for these reasons and will wait until the SkyWatcher units become available, whenever thatmight be. So, to sum up, potentially a good product but let down by the lack of thumbscrews and the price which is why I gave it only 3 stars.


I'm sorry you were unhappy with this Andy but, I think you've misunderstood how this works - we only use one thumbscrew against a brass compression ring so that it doesn't marr the polar scope. This is a more expensive option to produce than basic grub screws and should offer a more secure fit without damaging the polar scope as the brass ring tightens around instead.

Looks good but doesn't fit!

This appears to be well made, if rather expensive, but sadly it didn't fit the polar scope in my EQ5 mount, so I had to return it. I measured the internal diameter of the adaptor, and I made it 29.82mm - it would need to be 30mm for my polar scope.

I bought this to use with the skyguider pro to help with polar alignment and avoid crouching and back pain. Unfortunately itís almost impossible to achieve any focus of the retinal. Iíd say the collar is difficult to fit as after the first time the brass banding bends out of groove. Also the 1x is too small and the 2x with the collar you canít achieve focus.


It sounds like this isn't a good match for the iOptron polarscope. We've not experienced this on Sky-Watcher or Celestron polar scopes. Please get in touch if you would like to return this for a refund.

Perfect fit with the Star Adventurer
Thursday, 11 June 2020  | 

Bought this in the hope that it would fit the polarscope of the Skywatcher Star-Adventurer - and it does. Pretty expensive for what it does but cheaper than some alternatives. Whilst not having had the opportunity to try it out with my OTA still awaiting shipment, it is pretty obvious what itís benefits are; particularly at higher latitudes.
