Re: Astronomical Point
- I want to apologize to the Loch Ness folks for breaking my own rule
about the fulldome mailing list: stick to the topic! And the topic
is fulldome video, not (to be honest) astronomy. I will allow
further posts on this thread till it dies out, but subsequent
astronomical debates will be taken offline.
I feel I do need to defend myself in light(ning) of a few statements.
I'd ended my inappropriate post with:

too, especially among those who claim to have found evidence for it
on Venus. :) But my point (and I stand by it) would be that
lightning as it is almost universally illustrated in planetarium
visuals -- i.e., as big wonkin' bolts -- would not be seen on Venus.
I was jumping to conclusions in suggesting that the lightning
illustrated in the Loch Ness visuals would look like that, but I
addressed my comments to the historical illustration of lightning in
planetariums when I noted that theory and evidence both "should have
kept us from putting lightning over our Venus panoramas years ago."
And in fact, I've argued against depictions of lightning on Venus
long before I arrived at the Rose Center. On DOME-L, as a matter of
fact. (Hmmm. I wonder if I can find those posts...)

ionosphere. At least in terms of lightning-bolt-style lightning.
For those who are interested, we can continue this discussion
offline: Carolyn Petersen has already presented counterarguments in
a private email to me, and I'm sure we could include others on our
