I gave it away along  with a lot of stuff I put  out in front of my place when selling it last fall, including that book.
I can kind of appreciate the why of this.  I found it similarly not used so much. It’s not chock o block full of info, but some of the charts for simpler to find objects and basics on identifying stuff in the sky was def useful as a beginner. And even after gaining some proficiency I would bring just that out on some nights witha. Red flashlight and use it’s charts to find stuff. And /or doing that, using that book, with someone new to the night sky, it’s perfect for that.  But it didn’t get a ton of use at my house when i owned it. It taught be some important basics on how to identify things in the sky, field of view and scale of constellations  and relationship to each other, etc.. in an easy to digest way for a beginner.  But didn’t take long to outgrow it.  I gave it away along  with a lot of stuff I put  out in front of my place when selling it last fall, including that book. It went fast , hopefully someone is actually using it. It’s sort of like charts for beginners. I found  it pretty intuitive and truly educational for what it is.
