<p>The <a href="http://nova.astrometry.net/user_images/3099418" rel="noreferrer">first image</a> is of the Cygnus region with north to the left.
It is 73&deg; wide and 55&deg; high, with 65 arcseconds per pixel or 55 pixels per degree.
Bright stars include Deneb (&alpha; Cyg) left of center and Altair (&alpha; Aql) at upper right.</p>

It is 37&deg; wide and 66&deg; high, with 80 arcseconds per pixel or 45 pixels per degree.
The bright object left of center is Saturn, which was at that position around 2019-07-29.</p>

This is *really great*, thank you! fyi I've just asked [How (the heck) does Astronetry.net work?](https://astronomy.stackexchange.com/q/33575/7982)

<p>I'd like to establish the FOV and scale in pixels per degree for these images, so I need to know what part of the sky are these photos of and what are a few of the stars?

<p>I wanted to ask for an estimate of the latitude. I guess that's only possible if we assume the bottom edge is parallel to the horizon.</p>

[Astrometry.net](http://nova.astrometry.net/) successfully plate-solved both images.

The [first image](http://nova.astrometry.net/user_images/3099418) is of the Cygnus region with north to the left.
It is 73° wide and 55° high, with 65 arcseconds per pixel or 55 pixels per degree.
Bright stars include Deneb (α Cyg) left of center and Altair (α Aql) at upper right.

The [second image](http://nova.astrometry.net/user_images/3099463) is of the Sagittarius region with north up.
It is 37° wide and 66° high, with 80 arcseconds per pixel or 45 pixels per degree.
The bright object left of center is Saturn, which was at that position around 2019-07-29.
