Very helpful.

Thanks

So the smartphone compasses are deflected by the Polarie? I thought they worked off GPS so they shouldn't be.

See post on this.

I do find the most accurate method with the Polarie is the polar scope. But as you say you need to set up the tripod so you can kneel behind it. The older polar scope does not have an illluminator. I got a Skywatcher one and its OK but does not really turn off.

Do you find the SW illuminator can be dimmed enough to allow clear view of Polaris? Did you find a US source? Unfortunately postage from GB to USA is expensive for eBay sources.

Yes it does but it does not attach that well to the Vixen Polar scope. The latest version of the Vixen Polar scope has a nice looking illuminator. But I don't want to have to buy another polar scope. Also I see a nice looking illuminator on a Japanese site. But they are hard to deal with, don't speak English well and slow to respond.

That's what I'd expect for this FL.

I saw this wonderful feature on a prototype Toast Techonologies Polar alignment that used GPS and you simply adjusted the mount until a dot was in the centre of a circle it created. I haven't seen that come to market though.

I'd expect a purpose built alignment system can be calibrated for magnetic deflection.
