With visual I mean observations/detection/tracking in the visual
wavelength range, i.e. roughly 200 nm to 1000 nm. CCD's, telescopic, it's
all on-topic, as long as the observed photons are in the visual wavelength
range. Neighboring wavelength bands (such as IR) are marginally on-topic.
The further one goes away from that band, the more off-topic it becomes.

Yes, I'm aware there is no 'logical basis' for excluding other
wavelengths. However, this is what SeeSat-L was founded for and with which
most subscribers are satisfied. The usenet-group voted on in Spring has a
charter that is also very restrictive (no radio observing) and got
overwhelming support.

As this meta-discussion is off-topic, I would ask everyone not to reply
to this message, instead reply on UseSat-L@lists.satellite.eu.org (to
subscribe send a message with the word "subscribe" in the SUBJECT to
UseSat-L-request@lists.satellite.eu.org) which was started for exactly
this type of discussion
