Recently I got into astrophotography. So I'm really interested in trying to get a 1:1 pixel ratio. If you aren't familiar here is an overly dumbed down explanation: when shooting planets you take a video of 2-5 minutes and then take the several thousand shots, then stack several hundred to a few thousand of the best frames, and therefore get a much cleaner image. The problem is that The 7d compresses down to 1080 instead of cropping down to 1080.

A kind "Hello" to all 7D astrophotography fellows!

The only reason (for now) I created an account on this ML forum is your post: I want to give you a "heads up" ... you are not alone!  :)

Being a professional photo journalist, I got my Canon EOS 7D (1st edition) in spring 2010. Over time, newer camera bodies were added and the 7D eked out a shadowy existence in the closet. Having been a visual observer for decades, I only started astrophotography three years ago (2020), but initially wanted to use the cameras and lenses I already had.

Of course I did some research and that's how I found MagicLantern. ML was and is a great help for astrotography with the 7D because it offers very comfortable and flexible settings for long exposure image series in bulb mode. This really inspired me because it allowed me to use a very mobile setup without a lot of additional cables, controls and displays.

When night sky weather allows - which is rarely they case here in the Alps - I love doing deepsky imaging. I also photograph moon phases and sunspots. The longest focal length I have is F=500mm which is way too short to capture planets. It is even too short to capture a highres moon mosaic - which I would like to do.

I get to the point:

In the last few days I've come across indications that it is possible with ML to film the 5x magnifier of the 7D's LiveView, which in my case would correspond to a 5x "Barlow lens": Effective 2500mm focal length!

Unfortunately I can't help analyzing / developing this software feature but rather would need some hints / support what and how to use it with the 7D.

So please count me in as one curiously having this feature in mind.

My 7D with firmware 2.0.3 has ML up and running. How can I add / use this interesting 5x LiveView capture feature? I have no idea ...

Your help is much appreciated!

Clear Skies and thanks to all you bold ML developers,
