No image when connected to telescope

[Dennis_from_Hampshire]

When I connect Backyard EOS to my telescope I unable to take pictures.  When I put a lens on the camera Backyard EOS works perfectly.  Is this normal behavior or do I perhaps have a corrupted file?

Thanks.  Dennis

Did you hit the connect button in the upper left corner of the BYE user interface?

Looks like you did not.

Regards,

The camera is a Canon EOS Ra, designed for low-noise astrophtograpy.

This picture was taken when the camera was disconnected. The camera is connected when taking pictures through the telescope (doesn't work) or with a lens attached (works fine).

You should take a few hours and go through all your camera settings.  Knowing the limitation of your camera, and what it can do, will help eventually.

Your camera has a setting to allow (or not) taking pictures without a lens.... please enable this feature using the camera settings, and you should be fine.

There may be a setting in the camera that is preventing it from taking a picture without a lens. This needs to be disabled.

I have additional suggestions...Upgrade and Simplify.

Upgrade to 3.2.2. There is no charge and it fixes issues that you may encounter with the older version.

Simplify by saving RAW only to the PC, instead of RAW+JPG to both the PC and the Camera.

Once you get it working with those settings you can try to complicate things by choosing other options.

Also, I would suggest only using BULB for exposures longer than 30 seconds. Use Tv values for exposures that are 30 seconds and shorter.

Finally, you may find that shooting with a high ISO will give you excessive noise. Try 800 or 400 unless you are in Frame & Focus.
