Lunar Eclipse Wednesday Night
http://sunearth.gsfc.nasa.gov/eclipse/eclipse.html
Looks like we are supposed to have clear skies. Eclipse starts around 6:43 Calgary time, becomes full 8:01. For those who haven't seen one before, be sure to be watching it as it becomes full. Quite a sight and no special glasses required.

Are we allowed to loot during this period?

Of course! Everybody knows that when theres an Eclipse there are no laws and looting in particular is encouraged.
If everyone loots everyone else then everybody should come out even except for the experienced and efficient looters, the come out on top.

Now that's a great idea, I haven't used my new digital SLR hardly at all (not that I'm a resident photographer), good thing to try it out on.

During the last eclipse, I took out an old-school film SLR and shot about 20 shots at various partial and total phases. I don't have any good scans, so no attachments, but I'll tell you of my experiences anyhow so you can make better guestimates of your own shooting. I used ISO 400 slide film (Fuji Superia I believe) in badly light-polluted skies. You can adjust my values for whatever you're using.
General info:
-270 mm focal length gives reasonably good-sized image of the moon with some detail readily visible. You'll see maria and brighter areas easily, but likely not any detail of craters, etc.. If you can't do at least 200 mm or greater, I wouldn't expect anything other than vague dark and light areas...focus on framing and colour instead. All numbers given below based on using 270 mm focal length.
-For eclipsed phases, you'll need longer exposures...stability is critical. A little bit of "mirror slap" is evidently not too critical, but any jiggling of the remote release cable will blur everything you get. Therefore, do two things: first, get the most stable base you can, and second, use the "hat trick" ... block the lens with something, and then use that something (the hat) as a manual "shutter" once the camera has stabilized from triggering the release. If you have mirror lock-up, all the better.
During Partial Phases (nearly full):
-@ f/16, 1/500 (or shorter) will give some surface detail on illuminated portion. Any longer exposure tends to wash out detail
-with less than 25% eclipse, I never managed to get any detail in the eclipsed portion because the illuminated portion completely washed it out. Maybe you could find some detail with digital post-processing, though.
Partial Phases (>50% covered)
-@ f/8, 1/250 to 1/500 exposures gave good detail of illuminated portion
-@ f/5.6, 1 second gave good exposure of eclipsed portion
-@ f/5.6, 4 seconds over-exposed entire moon
Totality
-My best shot was f/5.6, 4 seconds about 10 minutes after totality
-f/5.6, 2 seconds was OK, but a little dark. OK if you want to digitally post-process
-f/5.6, 10 seconds looked pretty good, but sky motion starts to become a concern
For fun, I tried a 60-second exposure. In 1 minute, the sky rotates about one half of the moon's diameter, yielding a very blurred result unless you're tracking the sky. The result was very bright, but the short answer is, don't bother!
Again, these are just numbers from a single experience...those with DSLRs will have immediate feedback, but maybe the above information will provide some additional input (above and beyond your 2.5" LCD screen). I'll try with a DSLR tomorrow and post results if it's at all clear.

As I see it, the problem is that it's during a Flames game. Will anyone remember to go out and look?

If only there was a poster on this board with a penchant for picture taking, that also happened to live in an area with significantly less light pollution than us city slickers.

When I see a lunar eclipse, like the one I went to last year in Hawaii, I think 'Oh no! Is the moon eating the sun?' I don't know. Because I'm a caveman -- that's the way I think."

Norm!

I'm going to take credit for this and try to frighten my neighbours into paying me vast sums of money to turn off my "moon blocking shield"
It was developed by Dr Parsons over at MIT, I like to call it the "Alan Parson's" Project.

Just don't interfere with my moon base; my moon base is divided into two units, Moon Unit Alpha and Moon Unit Zappa. ...

Thanks for the helpful post. I'll be out with a tripod and a 200mm telephoto. Would like a longer lens but then with the digital crop factor it comes to 300mm so it should be decent enough.

That is commanded by Capt Koening, who gets it on with the freaky shape-shifting chick.

This may have been mentioned already, but apparently we should also be able to see a dying spy satellite(USA 193) for roughly two minutes, as its lit by the sun at around 7:08-7:10pm.
What's cool too is the U.S. has plans of blowing it up with a missile over the Pacific Ocean, so two hours later we may be able to see pieces of it as it burns up entering the atmosphere.
Here's more about it: http://www.canada.com/edmontonjourna...6fb71d&k=83587
