Yes... Best resolution & contrast is the day before so there is just enough crater shadowing to provide some depth. If you take off the blue filter for viewing the moon, it looks like every other full moon. :)

Do you have the regular Moon filter ? It makes it much easier to see the moon . Blue filter is very pleasing but it's best used on Jupiter .

QUOTED IMAGE

Very nice image . However the 7D is a 1.6x crop camera so that gives you 1920mm .
600mm X 1.6 crop x 2xII = 1920mm or 600mm x 2xII x 1.6 crop =1920mm . Reguardless how you figure this is what you get mm figures . FF starts with the 5DII . Anything before that is a 1.6x crop (APS-C size) camera .

The 7D, and other crop cameras (1.6x, 1.3x, etc) do not change the focal length. I understand what you're trying to get at though...if you want to fill the frame similarly with a FF camera, then you'd need 1920mm. It's a "FF equivalent" focal length.

If you were to crop the borders of a FF image to the size of a 1.6 crop sensor the image would be the same as the crop's(smaller resolution, but otherwise the same using the same setup (lens, settings, position, etc)). Since cropping a FF image can get you the same image of a 1.6x crop camera, does that mean the focal length changes when you crop? See? It doesn't right?

Sorry, I just wanted to clarify that.

Your camera is a 1.6x crop , not a FullFrame (FF) . That means whatever lens combination you put on your camera you have to multiply by 1.6 to get the correct frame size for your camera . IF your camera was a FullFrame camera there would be no crop factor so that means your original figure would be correct . Read this and you will understand better what i'm talking about :

Yes, I understand that. I'm just saying that it (crop factor) doesn't actually change the focal length of the lens/extender combo you are using. That new focal length you're talking about is what you'd need on a FF camera to fill the frame with the moon without cropping. The focal length doesn't change just because you're using a crop camera.

Technically, you don't "need" to multiply the crop factor if you don't want to. The only reason you would use the crop factor is if you wanted to find out what lens to use on a FF camera (or if you need to convert it to a different crop sensor size) to achieve the same FOV. If you don't have any FF cameras (or any other cameras with different sensor sizes), then that crop factor is meaningless (for you).

You know everyone knows it does not change the physically mechanics of the lens and extender mechanically on the focal length . All accessories are preset and you can not change it . BUT when you attach it to a camera , IF it IS a crop camera to give correct measurements technically you have to multiply the factor of what your camera is to the lens and extenders FL in order to project the correct FL for the image taken . I know exactly what you are sayin and by all means if you do not want to multiply the factor you do not have to but if you do not then since everyone knows it is a crop camera they will know you are not giving correct FL figures for your 7D and it looks like your denying it's a crop camera when in fact it is and there is nothing you can do to prove otherwise . It just shows you don't agree with the crop factor of any camera . Here is another link you can check out and you can search many on the web . Maybe when you find a link backing up your statement then by all means please post it here . Til then i have no other words to say , i'll just keep my thoughts to myself .

In case you missed it... last night was a "Blue Moon"... I took this with my tripod mounted Canon 5D MkIII and Canon 70-200 f/4L IS lens at 200mm f/8 1/30 ISO100. I also used a wireless remote to activate the shutter.

If you don't have any FF cameras (or any other cameras with different sensor sizes), then that crop factor is meaningless (for you).

At the risk of oversimplifying and/or stating the obvious: I think the point they're trying to make is the size of the object photographed will appear bigger on a "crop" camera vs FF when the lenses FL are equal. So if you use an 85mm lens to shoot a picture of a man's head, and he's standing 20' away from you, on a FF his head will take up 25% of the image. If you used a "crop" camera and the same 85mm lens and took the same picture his head would take up 40% of the image giving the appearance (illusion) that you used a longer FL lens. So, in order to get a similar image on a FF camera you'd need to use about a 135mm lens to make your picture look relatively equivalent to the one you took on a "crop" using an 85mm lens. So yes, technically the "crop" camera does not change the FL but the resulting picture it produces gives the impression that it does. In order to discuss photo's and how to replicate them across different formats you need to use the crop factor to help determine what lens you'd need to use to produce an equivalent image.
