Fingers crossed ☄️

I’ve been trying unsuccessfully for a week to spot Comet Neowise. Last week I drove around my town trying to find a dark enough area and finally did but the weather didn’t want to cooperate and it was too cloudy. Tomorrow (7/29) is supposed to be a clear & cloudless evening so fingers crossed that I’ll spot it and I’m really hoping this app will help. 🤞🏾🤞🏾 🤞🏾 If not, I hope anyone living in the year 8820 will have better luck.

UPDATE: 7/29
SUCCESS thanks to this app!! I’m so excited. ☄️ I found a pretty dark area near a private airport a few miles from me and opened the app. It worked perfectly and I could definitely see the comet. ☄️ It’s very cool. I could also make out the tail a little bit. Only thing that would make this app superb is if it had a photo taking capability. But, I was able to download an app for binoculars that took photos even tho they came out a bit blurry. I’m a happy camper now. 😁

First your location has to be on I always have mine off. So go out side to get a good GPS signal. Then turn your location on. My Compass app had offloaded to save space so open up your Compass and make sure where it says North is makes sense. Then you can close your Compass go back and open your Comet Neowise app and mine worked fine. Hey man you should let us give you a dollar or two. I looked around for two days for something to tell me where I can find the comet. All these complicated astronomical apps are fine if you use them all the time but I didn’t need all that right now.

Thank You!

I’ve been looking for something help see NEOWISE with my family and came across your simple to use app and although it’s been too cloudy everyday here we are all hoping to get a glimpse. This app does the job perfectly and big thanks to the developer for making it easy and free. With luck my daughter can see it before it goes away for 6000+ years! Can’t say enough about the generosity of this developer. Kudos my friend!
