Planet imaging: camcorder vs webcam/laptop

Planetary imaging is mainly "lucky" imaging thus good shooting condition is the king.
To pursue the best possible sharp/clean and crisp images for stacking, people try to use the imaging devices that have
high frame rate (to "freeze" the seeing), and
less compression (to reduce compression algorithm induced artifacts).
Technically speaking, these well known devices (The Image Source, Lumera, etc.) are really industrial imaging cameras, not consumer webcams.
IMHO, your camcorder meets the first criteria but not the top game in the second part. However, your result still looks great!
BTW, the only consumer grade camcorders that meet the second criteria are the old, long discontinued SD, bulky camcorders using DV25 codec (digital Hi-8 and friends).

Been there, tried that. Ended up (for now) with a DMK21AU618.

BTW, I went into the camcorder menus to see if I could up the framerate, but no dice. Then I noticed it had a highest resolution mode (MXP) that it warns "does not transfer to dvd", but I'll give it a try on registax and see how it looks.
It has a setting for "x v color" that extends the color gamut, but warns that it will only work with compatible HD TVs, anyone ever try that for astro?
