OK, I feel better.  My images are no worse than yours.  I always wondered
how people get those clear top to bottom images.  Apparently, it's not so
easy.

I think the last image I captured was 15 years ago.  With GOES, I think the
polar orbiters are going obsolete and not being replaced.

Actually the next generation of polar orbiters are due to be launched
starting this year.  More information:

The newest 137 MHz orbiters are using digital image transmission to obtain
about ten times the ground resolution and more channels.
