Nikon P900 Question

Recently I tried taking photos of the moon on a clear night. No obstructions, it was away from any trees or buildings. The P900 was set to the moon setting. I had the camera braced against a doorway, so there was no perceptible camera movement. Unfortunately all images came out blurred for some reason. When I pressed the shutter button, it would go into focus, then come out of focus. It did this for 4 separate tries and then I gave up. Anyone using the P900 have this issue? I’ve taken moon shots with it before with success. Any explanation or advice would be appreciated. Thanks.

Since you did this before and I assume using the same focusing method on the camera, I'd go with atmospheric conditions. The sky can look quite good to us, but be very much in motion for photography of astro objects. Mahy now use video to get good images, between mostly bad ones, for stacking. Also, objects low in sky, subject to lot more atmosphere. I just recently tried to shoot jupiter on what was a nice, cloudless, cold night, just got a blurry ball using a small refractor.
If you check astrophotography and "seeing conditions"? you'll find discussions on this, how settled the atmosphere is, cells of air and size, etc.
Finally, just thought of this, if you were shooting over a neighbors AC or heat pump, they can really cause the air between you and the moon is jumped every which way, chimney would do the same. At night, you might not see it, but the camera sure would!

The moon was nearly straight overhead, so nothing from the neighbors. It was just cold. The phenomenon was that it would initially go to focus, then jump out of focus. Hopefully we’ll have another clear night and it won’t be so cold. I’ll give it another go, but with a tripod. I know it can shoot a sharp image. Here’s the last one I did some time ago.

I have Canon SX 60 and 70's. Sometimes they do it when at some pecticular fl? Good luck.

Things are tricky at 2000mm eq.

OK, I do find that pushing the SX cameras beyond a certain point just does not work well. Don't know if that applies in your case. Seems like maybe 900 out of possible 1365? Use the cameras on travel trips which haven't occurred in 22 months, so less than clear on such things.
Good luck;
