CANON-DUAL CAMERA

[Carlesa25]

Hello: I have two telescopes mounted in parallel with a Canon in each one, I use the Dual Camera option and it works perfectly but I would be interested in being able to change the ISO in the second camera, that is to say the same acquisition plan but with two different Isos, from At the moment I have not managed to get it to work, is this option possible?

When you use the dual cameras feature in a master and slave relationship, the slave version uses the master version's capture settings. This guarantees that both instances will be ready to dither at the same time. I do not believe that what you want is currently possible.

Hi, thank you for you answer.

I think it would be an option to consider since normally when two cameras are mounted it is in different equipment and with different characteristics.

It is normal that the acquisition plan is the same in the two Master / Slave cameras but the option to change the ISO (in the slave camera) is important since the response of a GSO RC 6 "and a Refractor 90mm f / 5 is very different and the way to optimize the shot is to play with the ISO of this second camera.

Currently I solve this issue (somewhat handmade) by starting the two cameras independently, the same number of shots and times but different ISO and launched the shots of the two cameras at the same time; the result is good, two simultaneous sets of lights, Wide Field and Narrow Field but with compensated lighting.

I sincerely recommend that you study the proposed option of a different ISO in Master-Slave. Regards.
