T2i Shoots Moon @ 5040mm

here is a quick video of the T2i shooting the moon in it's 6x (standard def) movie mode.

TWO lens setups we're used...
1) Canon 300mm 2.8 + 1.4x + (T2i @ 6x) = 2520mm
2) Canon 300mm 2.8 + 2x + 1.4x + (T2i @ 6x) = 5040mm

Fstops we're between f22-f36 - 1/60th / ISO between 100-800

i probably could have just shot this in HD and brought it into a SD timeline and zoomed up to get the same results but thought id just give it a go to see what i could get.

EDIT/CORRECTION: i reread the T2i owners manual and realized that its supposed to be 7x not 6x magnification. here is the adjusted specs...
1) Canon 300mm 2.8 + 1.4+ (T2i @ 7x) = 2940mm
2) Canon 300mm 2.8 + 2x + 1.4x + (T2i @ 7x) = 5880mm

since the T2i is a 1.6x camera...am i supposed to factor that in on top of the 7x as well?
maybe someone here would know the answer.

Wouldn't it have been awesome if you somehow caught a small meteor crashing into the side making another crater and spewing rocks in zero gravity, wonder how much you could sell that footage for lol but damn nice the craters are awesome

although not as dramatic as your imagination would suggest, if you check out 1:03 of this video there is a very quick swoop of a small black image passing from top to bottom of the moon. my guess is maybe a bird flew into the picture? at this magnification i would think it would have to be pretty far to even show up.

No, you don't need fast, but you do need long. IIRC the moon subtends 1 mm on the film plane for each 100 mm FL. and is surprisingly bright.
A driven equatorial helps too.

Good to know. There's an old Sears 70-300 4.0-5.6 on craigslist that I've been on the fence about. i just might pick it up!

the moon was pretty bright this night i shot it so i stopped down a lot. so yeah, "fast" doesnt seem to be needed although im not sure stopping down as much as i did it the best idea either since diffraction would be a factor.

Zooming in the HD footage in an SD timeline would not give you anywhere near 600%, more like 225% so you did it the right way for maximum magnification.
