Nikon P1000, a real planetary camera or a gimmick ?

Nikon released this superzoom (yes, 125x Optical, not digital!) and it has a virtual FL of 24-3000mm equivalent. But it has a small 1/2.3" (4.5x6mm) sensor which is a crop factor of 6, so actually it is 4-500 real mm range and at 500mm it is f/8 so its objective diameter is 60mm when fully zoomed in.
It shows even the Moon image covering, and when I calculate (it is 16MP: 4608 x 3456 pixels), so one pixel is 1.3 micron wide, no better than a phone cam.

IMHO, this is, just like a phone cam, nice when enough light, and maybe filming Jupiter and postprocessing with Autostakkert might show some results, but the Jupiter image at 500mm is only 0.1mm = about 70 pixels wide, but at 1/30 second it might be too dim.

Holding a phone cam behind an eyepiece of a telescope with decent aperture and more magnification and Autostakking the video will have a better result.

not really a gimmick but very much a tripod camera as trying to focus on anything hand held at 3000mm is impractical. However with raw and a travel tracking mount it could be a good travel/budget solution, I use an FZ1000 for same reason on my vixen. Be aware though small tracking mounts have poor tracking with long focal lengths, I think polarie is about 200mm and my testing confirmed I couldnt push passed that with star trails, so check specs of tracker first. Maybe its a camera for high rise apartment bedroom peepers?

Diameter of the lens is proportional to resolution. So if it's only 60mm, then the images it produces will only be as good as a 60mm refractor. I wouldn't call a 60mm refractor a planetary telescope.
