I have noticed that too and I probably should have mentioned it, I like useing 2 shades of yellow/orange but
they have to be fairly close in light transmission for best results. It's not going to be 3D like Avatar but it will add to the experience.

What about splitting a pair of polarizer filters, putting them in with the polarity at 90 degrees?

Another interesting trick is when you want to directly compare 1.25 eyepieces. You just install each right next to each other!

...assuming you have a perfect beamsplitter.

Comparing different eyepieces in binoviewers at he same time would only work is powers were within 10% or both eyes would not merge images. Assuming your eyes can accept that much difference, and the in/out focus is within limits to look through with both eyes. Might be a good way to show different apparent fields of view with at same power (but most individuals probably wouldn't have that type of duplications).

I have tried this technique in the past with a red and blue filter but my red was a bit too dark even on the moon. This caused my brain to favor the much brighter blue. If I had a lighter red the result probably would have been much better. Trying blue and yellow seemed so so.




Noticed Jupiter favored the lighter colors, while the moon favored the darker colors. I have never seen Venus cloud tops, but perhaps I may see something other than phase with light or dark colored filters.

P.S. Televue now has a planet filter, which I have heard keeps red spot red, but makes bands and caps darker brown.
I have used skyglow on Jupiter with great sucess in seeing contrast.

That would only work with 3D movies.
I believe may become polarized coming through the atmosphere if looking near the horizon.

You guys are so silly! I didn't mean to look through them at the same time! I meant use your right eye to look through one, and then use your right eye to look through the other!

That was pretty obvious to most of us. But you'd still have to switch EP positions because beamsplitters aren't necessarily perfect. In my MaxBrights there's a noticeable colour cast difference between the two sides, for example.

I'd cannibalized may filters for various experiments and was left with only blue and light green to try.

No go with that combo for me.
