This works quite easily and is very useful with an equatorial mount. I keep it handy always to check the alignment. Well worthwhile.

An excellent aid to polar alignment. I am a 72-year-old fat man with a bad back and a stiff neck. Kneeling to look thru the polar scope would probably have me reeling in agony for days afterwards so is not an option. The first time I used this device it took me 15 minutes to get an accurate alignment without contorting my body. I reckon with a little practice I can get it below 5 minutes so 12 out of 10 for this product. I don't understand why some people give this device negative reviews, the onscreen instructions seem pretty straight forward to me. BYE THE WAY, get one of the universal adapters so it fits on the underside of the dovetail/losmandy bar and works on any mount. I bought this

ADM Dual DV Series Dovetail Adapter For PoleMaster Mounting £44

Complete waste of money. It’s needs to be plugged into a house socket for it to work.
Doesn’t work from battery power.
Doesn’t work from an extension.
Only works from a plug socket.
So unless you have electric in an observatory, you will need to be able to remove the roof from your house to observe the night sky due to the plug lead not being 60ft long . .
I’ve tried numerous setups and ways to get it to work and every time it freezes........then starts again for 1/2 second then freezes again.
So instead of it taking 3-5 mins for accurate polar alinement it’s takes 7 1/2 hours... oh look it’s morning better pack everything up.
I’m getting in touch with the makers and asking them to refund my money as it has nothing to do with first light optics that QHY made such a useless piece of junk.

First impressions are what count and my first impressions were a little bit underwhelmed.

I finally had a partial clear night and managed to test my new Polemaster with the EQ6.
All in all the build quality is rather nice, with all round quality feel.
Where it let itself down was being out of focus right out of the box despite being allegedly focused to infinity!
No biggie as Polemaster comes with a microscopic Alan key to allow re-focus but where your out in the field in the long grass what ever you do don't drop the Allan key or you'll be going home in tears
The second sad tiding which I think inst really a show stopper because its close enough was the initial alignment circles in the software don't fully encompass all the alignment stars. Some sit on the alignment circle or just outside.
Its close enough to get alignment I think but couldn't tell for sure as I was doing very wide field and couldn't tell how bad drift was. It seemed OK at first glance.
The actual alignment process was a breeze and only took a few minutes once I got the focus sorted.
When I attack narrow field I'll get a better understanding of how accurate the polar alignment is/isn't and may revisit this review.

In summary Id give 4/5 for the hardware and 3/5 for the software.

I live in a light polluted Bortle 6 area and don't have any permanent setup - though I manage OK
It's no exaggeration to say polemaster has revolutionised my setup from fumbling misery to smug delight.
I now perform a very accurate (and enjoyable) polar alignment in about 3 minutes. It's solidly made, and was easily fitted to an HEQ5 in a few minutes.
I worried about it working due to light pollution, but it works perfectly first time, every time.
It is the best non-essential astronomy purchase I have made, though for me, I would now class this as essential kit.
