The Nikon D80 that I shot those photos with has a 10 mp sensor, less than some smart phones, but much better for rocketry because of the lens.

That said, these images are almost 10 years old and my D80 is a dinosaur compared to the 20-25 mp cameras of today, but with good glass, it will hold it's on.

Those are always great pictures!

Quite correct... I guess most people think "more megapixels= better camera" when nothing could be further from the truth. For awhile it's all the camera manufacturers and retailers wanted to talk about-- the most megapixels.

Unless you're blowing a picture up to the size necessary for a billboard or covering the side of a bus, 10 mp is plenty for most applications. The more MP the bigger the file size. I always kept my Fuji Finepix "pro-sumer" camera set to 5 mp, which is fine for most pictures, unless you want to blow them up over poster size, then 8-10 is better. Anyway, a good burst mode IS nice (my Fuji will do 33 pics in 1.3 seconds in burst mode-- guaranteed liftoff pics if the ignitor works); the only thing is that's ALL you'll get, because it's an older camera and the buffer is slow writing the pics to the card, so it takes about 15-20 seconds or so after you release the shutter button before it's ready to shoot ANYTHING again... so usually I can't get any "in-flight" pics after the liftoff to about burnout, and then *maybe* some pics on the way down under chute (hopefully).

I compare having these huge megapixel rating sensors under bad glass to using a camera with large-format film (which was the only way to increase the "pixel count" in the old days) with a dinky button-size lens out of a cheap 110 camera... It just doesn't make sense... Good glass and good format size is the reason all those old Ansel Adams pics still look great nearly 100 years later...
