Hello,
lurking in the forum's topics I found that many of you are using an App in the Apple phones to create horizon data to feed to Ekos. I find it really useful so I'd like to do it too to have my backyard horizon well traced. Could you suggest some way to do it using tools commonly found in normal houses? (maybe a compass, at top) ?

Thanks

Luca

My suggestion is to set up your telescope, have the mount coordinates accurate (maybe do a few plate solves during the night on a few targets spread out over the sky) and then leave the telescope parked until daylight.
Then use the hand-controller to trace the outline of your horizon, using the view through the telescope. Write down the Alt & Az coordinates that you then can input as Artificial Horizon.

The advantage is that you get the exact horizon that your telescope sees.

I used my Android phone and two apps, Compass to get headings (azimuths) and MultiClinometer to get angle above the horizon.

We have high dew points here, and I didn't want to leave my scope outside as suggested above.
