hello
in night time you can not see the profile of the mountains or buildings in front of your balcony
of course you remember their position but a few degrees error is likely
with plate solving you can get azimut and altitude of your telescope
Sharcap could memorize a series of points P (azimut, altitude) and to plot a line
below this line you get an error message
Stellarium can read the series of points to plot a real landscape
is it feasible ?
Bye

Re: true FOV
Hi Alberto,
You can definitely set up custom horizon altitudes in stellarium - see http://stellarium.sourceforge.net/wiki/ ... ine_Method
If you can align your mount (even fairly roughly) during the day then you can move it using SharpCap and just write down the altitude of the horizon every few degrees across your view - a bit of a manual solution to the problem, but it only needs to be done once.
Aligning during the day can be done by marking tripod points after a night time align and then replacing the mount in the exact same position the next day, or by simply using a compas to point the mount axis north.
cheers,
Robin

Re: true FOV
Alberto,
Try this app, it is great. One week free trial, thereafter $0.99 every month, or purchase outright for $9.99: One mode allows it to use your phone's camera and position sensors. It uses Augmented Reality to superimpose the Moon and Sun and their paths across the sky with timestamps. At the center of the frame is a bulls-eye. It reads off Altitude and Azimuth. So even if you are not interested in the Moon and Sun, you can still use it to map the coordinates of your mountainous landscape. Use it during the day for that.
I have the app installed on my iPhone 12. There may be a version available for Android. You'd have to look it up.
