    Its not super dark here on the crystal coast so I have a lot of light in the area, but here are some shots from tonight.

    Any advise to improve my photo's would be appreciated.

    All were shot with the PEN-F & 17mm 1.8

    f/1.8, 20 sec., ISO-800
    P8096695.JPG

    This is in the upper left portion of the above shot. Strange light source.

    f/1.8, 15 sec., ISO-1250

    Used a 4 stop ND filter for this shot.

    f/1.8, 30 sec., ISO-3200

    Damn UFOs always photobomb the night shots.

    Your strange light source is almost certainly a satellite. Catching the reflection of the sun off the solar panels.

    Try shortening your shutter speeds. Even that 20sec shot is too long as it's elongating the stars making it more blurry than it should be.

    Very nice images of the core of our galaxy! The teapot shape of Sagittarius is easy to see, as is the stinger of Scorpius and the open star clusters M6 and M7 near the stinger.

    Is the trick of "dividing by 500" reliable? You take 500 and divide by the focal lenght (let's say you shoot with a 25mm, 500/25 = 20), which will give you the maximum number of seconds you can shoot before you get trails (in this case 20 seconds).

    Should be, but make sure you divide by 2 for the Micro 4/3rds equivalent. I.e. a 25mm in M4/3 would only be a 10s exposure.

    I was using the 17mm 1.8 and using the rule of 500 would have been a 30 sec. exposure and that would have given me longer star trails.

    Im looking at the Laowa 7.5mm f2 lens for these shots and the exposure would be much longer..

    I see the shots of our milky way others post and wish I could bo as well, but just seem to fall short...

    Thanks for the replys...

    Due to the crop factor of Micro 4/3, you would be looking at more like 14sec exposure in the rule of 500.

    One thing that most of the better milky way shots have that you don't here, is combining multiple photos together to increase the information provided. And then if you use dark frames, you can remove almost all the noise.

    Here's a good guide on how to do it (as well as use their free software). Keep at it.

    OP, those are some excellent results for the back yard night sky photography. You did a great job, I don't think there is much more you can do to improve them. They are good. Getting any type of stars in those conditions is difficult with challenging light pollution.

    Nevertheless, since you've got the techniques down, and the skills to process, consider planning a road trip to some remote area where you live. One that has a dark night sky. And use the star finder aps to plan for optimal time to capture the Milky way core on the horizon.

    Also consider mutlishot panorama for your horizon galaxy shot. Using a 50% overlap and 4 to 6 shots at 12mm will get you more resolution, ability to push NR one more stop, and more clarity and color in areas where there is light and detail.

    This is a 3 row, 21 shot panorama, in a dark night sky area of the Mojave Desert. Shot with a APSC. However I just switched to MFT camera this summer, I'm looking forward to using it next year during the galaxy season (Mar, Apr) to test it out in these conditions. Because there is no light, I used a low powered LED lamp to light up the foreground rocks. My goal is to get the same level of results with MFT as I did APSC. How bad is light pollution? That glow on the left is from Las Vegas about 80 miles away.
