Extra Reach for Shooting the Moon

Now here’s a novel way to shoot the moon: stack five separate Canon 2x extenders to boost the focal length of your 800mm lens. Supposedly (and surprisingly) this rig actually captured a decent photograph of the moon.

This was done by the folks over at BorrowLenses, who also did the crazy filter stacking thing we featured recently. When you have as much gear as they do at your disposal, you have a wider range of ways to have fun with gear experiments.


Update: Josh from BorrowLenses tells me that with 5 extenders, the moon was actually bigger than the frame and the whole setup was “bending and flexing”:

With 3 extenders the photo turns out a lot better:


Disclosure: BorrowLenses is a sponsor of this blog, but — like last time — we came across this story on Reddit first

    where is the picture!!!!???

    This post would be more effective if you also posted the photo that resulted from this rig.

    I’ll contact them and see if they have one

    What are you talking about?

    You reported: “Supposedly (and surprisingly) this rig actually captured a decent photograph of the moon.”

    Yet, you don’t have a picture, or didn’t even see it for yourself?

  • Jon

    You’re a photogteaser!

    No, sorry. Just came across this picture today on Reddit, and wrote that based on what I was told by them via email. If I had a photograph taken by this setup I wouldn’t have said “supposedly”.

    Will be updating this post with a pic if I receive one.

  • Michael C

    Fair enough, apologies. :)

    This post would also be most effective if Borrow Lenses actually had their own blog to share their photography adventures and there were to be a link on here to there :)

    yea, someone has one. http://bit.ly/9ChZLS

    I don’t get this, it reads as though he was surprised that 5 TEs made the moon bigger than the frame. 800mm itself is fine for capturing the whole moon.

    Doesn’t each extender reduce the sharpness of the picture somewhat?

    I shot with a 300mm and two teleconverters and got great results. There is no way you can reposition a rig like this fast enough between exposures and keep it steady – this has to be a joke.

    So what would be the focal length of this thing? Would it be 8000 mm(800×10)?

    Bit late.  5 extenders would be 800x2x2x2x2x2 or… 32×800.  25600mm

  • Evanhass16

    Also, the 25,600 would be multiplied by 1.3 because of the 1d mk4. So…33,280mm.

  • The Astronomer

    Yeah this has got to be a joke. There is no way you can get as sharp of an image as this shooting at 33,280mm and obtained with 5 2X teleconverters on an 800mm 5.6 lens. You would lose 2 fstops for each teleconverter. Even if you did stack all of them the image would be so dark you would not even be able to tell what you were shooting. Someone is trying to pull wool over everyones eyes.

    Probably be sharper if you track ever so tiny and stabilize in a over kill matter. :-D
