How can i tell Vega from Deneb and fix my backyard telescope alignment?

I was trying to calibrate my new 8-inch reflector last night using a star I was sure was Vega, but my goto alignment kept failing. I realized I might have actually been looking at Deneb the whole time, and now I’m second-guessing my basic ability to tell these bright summer stars apart from my moderately light-polluted backyard.

I’ve done this more than once. I was sure Vega was the anchor star, but the glow from streetlights kept turning the sky to mush and the star drifted around the field of view. It’s amazing how easy it is to misread a backyard sky when the lights won’t quit.

Last weekend I tried a quick alignment and spent ages chasing a moving reticle. If you’re wrong, the goto spins and you end up looping the sky instead of pointing at the target.

Maybe the real problem isn’t the mount or the camera, but the reference itself. In a bright yard a bright star can look right and still be wrong because of glare, perspective, or a longer than convenient focal length. I kept telling myself to trust the star chart, but it didn’t settle anything.

Do you keep a simple sky map handy to sanity check what you’re actually aiming at when it’s all washed out by lights?
