The extended good conditions I experienced on 3rd April have allowed me to do some more experiments with 3D/stereo pairs.

 

The consensus I'm hearing to date suggests 10-12 minutes is ideal in terms of time separation, but it's always good (and fun) to experiment for yourself.  smile.gif

 

Here I have posted a series of stereo pair images in 2 minute increments of time separation (4, 6, 8, 10 and 12 minutes).

 

I did also create animations so that you can watch and more directly compare the changes in "roundness" that result, but these are too large for CN. If you're interested, you can find them in my Astrobin gallery.

 

I'm interested to hear your thoughts as to which time separation gives the most pleasing result! (I have my own opinion on this, but I'll reserve that for now.)

 

Please note these are all "cross-eyed" pairs ... apologies for those who find far-sighted easier, but it was too much work to produce and animate both types. (Read: I'm too lazy.)

 

Here's the 4 minutes pair (you may want to click for the full sized image):

Hi Darren,

 

My preference is on the lower end (4 minutes, maybe 6). Then again, at 18-inches the cross-eye pair makes my eyes have to cross to where they would to view a sphere at 3-inches away, which would equate to 48˚ or 1.2 hours…

Actually, I prefer the longer gap myself (10/12 min) on my laptop.

 

Just for information, what's the key part of these? Are they just two images separated by a certain time layered next to each other? Or is there something else I'm missing?

Yes, they're two separate images set side by side. In both cases they are de-rotations of 6 image stacks, just centred on different time points.

Hope that makes sense lol.

Interesting experiment! I myself like the 10 and 12 minute versions as they result in more 'depth', but they seem slightly more difficult to focus. It's fascinating that Jupiter rotates so fast that even a few minutes difference can produce stereo images in this way. I like it!

I like the 10 minute rotation version the most.

Hello 

10 minutes for me.

Excellent test.

Clear skies.

Interesting ... on Astrobin, the clear consensus was 8 min. Here, it's 10 min!

What's interesting is that personally I'm torn between the more "natural" looking 8 and slightly rounder 10 min ... maybe 9 min would be perfect for me lol.

I had to switch the images L/R to view them with the "straight ahead" method, and only tried the 8 min version.  It looked great to me.  Very real and natural!

I do not know why but I find that the 10 minutes photos are the best for me, I find them more in focus. thank you
