canon camera - outputhdmi to tv


I wish to output my eos 600d hdmi feed to my tv so we can live view the moon.

I have attached cam to scope and get the live view for 30sec's then it shuts off.

If i rotate my camera selector knob the options all show on the tv as if i'm looking through the viewfinder.

When I select "Video" it says attach a lens.

Is there a way to watch without having to keep hitting the live view button?

I have a 600D but have never tried connecting to a TV.
Mine attached to my scope and made videos o.k.
The "Attach a lens" message does not stop you making a video, if you don't
attach a lens [or scope], it just videos a blur.
LiveView should remain on whether shooting stills or video.
Does the LV shut down after 30secs when connected to just the scope, or
only when connected to the TV as well.
If it does it when only connected to the scope, something is obviously wrong.
I assume that there is plenty of life in your battery. If only when connected to the TV, then I have no idea, maybe somebody else can help you.

Ive had my Canon 600D for 10 years , the last 4 years I’ve used it for Astrophotography, prime focus in Newtonian reflector telescopes
I’ve only connected mine to the TV using a HDMI cable for viewing still pictures and video playback , not live view on an object
I had a quick check on YouTube and the Canon site and the HDMI connection is generally for playback purposes

I use BYEOS software with my 600D for Astro image capture ( including live view ) with my 6” and 8” newtonian reflectors
It uses a micro HDMI to USB cable ( camera to Laptop )
Maybe you could use BYEOS on live view , and then link your laptop to your TV with a Standard HDMI cable to view the “Live View”
Could possibly work ?

Another thing to consider is : does the camera do live view video to tv longer than 60 seconds with just a lens,,? if it does then I cant help, but if it only does 60 secs with lens also, then I would assume the camera card is not fast enough to except the video data at the rate the camera is producing video, if this is the case then you two options,, 1) reduce the video quality settings or purchase a faster reading card ?
