    I would like to try to take some photos during tomorrow night's meteor shower with my GX7 if possible. I know I don't have the best kit for this, but I want to try for the fun of it.

    Newbie question about how to get it set to infinity focus. What does the red portion of the Panasonic manual focus meter mean? Is the red portion actually beyond infinity focus? Do I want the focus indicator at the very left edge of this, or where the white and red meet?

    My best lens option is probably my 25mm 1.4 wide open, and I guess it's best to set the WB to sun.

    Should I turn off settings like Highlight Shadow and i.Dynamic, so that the camera doesn't outsmart itself and try to compensate for the blackness of the sky and apparent under exposure?

    Should I use Long Exposure NR, or deal with noise in post processing?

    I.Dynamic (at least in the past) only applied to JPEG, so if shooting RAW, it won't be a problem. I would try and set a custom WB if you have a grey card (or other thing approximately gray). Depending on the average length of shot, and how fast you are shooting may determine whether to use LE NR in camera or not. It essentially doubles your exposure time (once to take a picture, once to Black-screen). If you can get away with doing it in-camera time-wise, it may be one less thing to do in post.

    Panasonic puts red coloring on meters to indicate "danger zones" -- areas where you're going to overexposed or underexposed. In this case it looks like it doesn't think you'll have enough light (too small of an aperture) for the shutter speed. Maybe you can slow the shutter a little.

    I would turn off the extras and develop the RAW files yourself since this is a special situation (very dark sky, long exposure, and meant to be viewed as white spots/streaks against a black background).

    My suggestion for focusing on infinity is that when you setup, manually focus on a bright star then leave it there.

    Yes, I can do that and I think it will work fine. I'd still like to know to know where infinity focus is found on this focus distance meter though.

    Ellsass, I don't think the red can represent what you are suggesting, because it stays the exact same regardless of exposure (even when very overexposed), and it's in the exact same spot on my Panasonic G6 regardless of exposure as well.

    You're right. He's wrong.
    Infinity focus SHOULD be right where the white and red meet. They give that extra space(red), to compensate for any inaccuracy.

    I'm also very interested in photographing the meteor shower. I have a G5 with a very good stable tripod and a remote trigger. My available lenses are listed in my sig line. What would be a good lens to use for getting the best results? Djarum made the suggestion to manually focus on a bright star and leave it at that. Sounds pretty cut and dried. I will be shooting in jpeg format. I know, I know, RAW would probably be be better, but my version of LR won't do RAW.

    Well, the meteor shower didn't turn out to be much at all, and I think the GX7 sensor isn't able to hold up very well to long exposures in darkness.
    But I still had some fun taking pictures, and as always the 25mm 1.4 performed well. The 14-42 PZ, on the other hand, was fairly disappointing for me.
