I have a probably very stupid idea for planetary astrophoto. I own a non motorized Celestron CST9.25 and I use a Baader maxbrigth 2 binoviewwer with 2 Televue panopticon 24mm as eyepieces for visual ( and really enjoy it ). I just bought an asi 678 mc camera for astropho. Would using one eyepiece to maintain the planet manually centered and the other one to shout the video with the camera a very bad idea?

   Hmmm,  might be better to shoot the video instead ; )    At least your typos are words, mine are usually unrecognizable mush.

It'll work.  You can use software to stabilize the video afterward.

Not sure on practicality, but there are flip diagonals that might work for you.  Vixen  There may be others..

[D_talley]

The Vixen will not work since the flip mirror will block the light going to the eyepiece.  I have one, they work well getting the planet on the chip but you cant actively use it while imaging. 

 

The OP question, will the binoviewer allow him to have a camera in one hole and a eyepiece in another.  Will the camera have enough focus range to allow the eyepiece to be in focus at the same time. You will need to test it during the day on a far object.

  No problem at all.  Your message was both well written and concise.  Honestly, I just assumed it was a casual typo with no inkling that you might be a non-native speaker. 

   I wish that I knew French as well as you know English.  Heck, I wish I knew English as well as you know English.

Much better phrased than i could, will do some testing indeed.

Will you be able to get your head to the eyepiece with a camera sticking out of the other eyepiece?

[balcon3]

What you really want is a 50/50 beam splitter diagonal that splits the light 50/50 into 2 ports that can be viewed simultaneously. These exist for microscopes but I have not seen one packaged into a telescope diagonal. It would certainly be doable, though, for someone who has the optical and mechanical knowledge.

Will do some testing this weekend and revert

[Etien]

It works!

I sometimes use my binoviewer as a very simple way to compare different eyepieces so it’s not a crazy idea.
