I have never heard of a digital angle finder without batteries.
Is it solar powered? Nice classic C8
I have a very nice analog angle gauge that requires no batteries. It works just fine. Cost $5
But I do prefer the digital type. One cost $11, one $26 and one $33. I like to have several because I loan them to friends to try the system. They try it, they like it, get their own and return mine so I can loan it out again.
The batteries are small so I keep spare ones in the box. Same battery that I use for the RDFs.
Why do people use degrees azimuth instead of 24 hours, which many catalogs use?
Converting degrees from the north star to degrees above the ground also sounds like it needs some math before one leaves. A very interesting math problem indeed.
You have taken something simple and easy and tried to make it hard. Clearly you don't understand the process.
You just read the AltAz degrees off of Stellarium or SkEye or some other readily available app. So very easy. Works day or night. Unaffected by light pollution. Just use the AltAz coordinates to go right to the target. Works great!
I never use paper charts. I have them, but they gather dust.
No need to memorize the sky or understand RA/DEC. No need to memorize constellations or struggle because light pollution robs you of stars to hop by. Just go right to the target. Sweep a little left or right and there it is.
Oh, I am learning the sky as I go, but my lack of depth of memorization has not held me back one bit.
