DIY side by side (by side) piggy back mount new
      #2492653 - 06/30/08 11:39 PM

I had this idea concerning the amount of time spent on an exposure, and how it would be efficient to take 2 pictures at the same time with 2 cameras. The weight would be a huge factor, so I came up with a way to do it with a guide scope and prime lenses.
One side I will just have the camera mounted in a static position, and the other is on a ball head. It seems balanced now, and the Orion guidescope can move front to back if need be, and the dove tail is long enough to come into play as well.

Now, only if the clouds and rain would go away, I would love to try this out on the Summer Milky Way.



The long lens on the Yashica is a 200mm f/4, and the Oly lens is a 24mm f/2.8 Sigma that got great reviews.

I love the set up. Nice mounting job - solid and made yourself. I was going to do the exact same thing with my 35mm cameras - but the medium format Pentax changed all that. The wood has natural damping qualities. You probably could work the shutter on one camera without causing any vibrations to the other.

If it became an issue, you could always cover the lens of the other camera for a minute, then uncover to resume the exposure. The EQ6 should have no problem carrying this load what so ever. To make for better balancing and less vibration on the weight shaft I used 2 weights up high, instead of 1 at the end of the shaft.

Let us know how it works out. I think it's a great idea.
