Canon 6D in Planetary mode



I am unable to control the ISO or shutter speed of my Canon 6D when in Planetary mode. I am using 64 bit Windows 10 and the latest version of BYE. I have had this new camera and BYE for quite some time, but only use regular imaging mode. Had great seeing last night, so I thought I'd try getting a video of Jupiter. It was all washed out, and I couldn't control the exposure. I remember doing this many times back when I had a Canon t5 with no issues.

Use of BYE's Planetary mode has been discussed many times. Here is one example (just search for Jupiter): https://www.otelescope.com/index.php?/topic/1687-planetary-live-view/?hl=jupiter


Did you uncheck Maximum Sensitivity in the settings screen?


Exposure simulation is easy to test while indoors in a semi-dark room with a lens on the camera. No need to waste a clear dark night.


This test will work in F&F or Planetary, since both use LiveView. The only real difference is what BYE does with the images.


Connect to BYE to the camera.

Activate LiveView and get a rough focus.

Set the ISO to something like 800 and the exposure to something like 1/1000 sec. The LiveView image should be dark.

Then start lengthening the exposure in large increments, say by factors of 10 (1/100 then 1/10 then 1 second).


Do you see a change in the LiveView display?


It is worth noting that the rate at which the LiveView images update does not slow down as you lengthen the exposure. In LiveView the Shutter speed acts as an artificial brightness control. You can also control the brightness by increasing the ISO.


A couple of other things...


1) Don't use BULB as the Shutter speed. This disables exposure simulation and you will be unable to control the brightness of the LiveView frames.

2) Don't try to focus on Jupiter. Focus your scope and BYE on a bright star then slew to Jupiter.

3) Always use the 5X zoom feature in BYE's Planetary mode. This gives you the maximum resolution

4) Adjust the shutter and/or ISO so that the resulting image of Jupiter is dark, but light enough to the equatorial bands. You can brighten the final, stacked image in post processing.


I hope this helps
