Has anybody attempted star trails with the E-M1?

    Like the title says, I'm looking for input from anybody who has attempted to stack a series of photographs for star trails using the E-M1. I'm looking for big sky swirls made with lots of images from the E-M1 over a period of hours and stacked with something like DeepSkyStacker. I'd really like to see some examples, if there are any, with some discussions on the settings used.

    Thanks,
    Nate Hahn

    I guess not, so I'll have to start. Here's my first attempt from tonight:

    This was supposed to be a set taken over 30 minutes, but my battery let out 6 minutes in and the spare was at home on the charger. The result is 21 images stacked.

    I used an em-5 for these. I'd love to see more people post these. I was a little afraid the e-m5 wouldn't be able to handle star trails when i bought the camera but it looks like it's doing a good job. Turned off camera noise reduction so i can take photos without have to wait for the camera to apply noise reduction leaving gaps in the star trail, and used an electronic cable release brand is Aputure cost around $25 on ebay from china, $44 on amazon.

    Shot them all in raw, edited them in LR4 (upped contrast and clarity,changed temperature and tint to get sky just right, made other smaller changes), used LR4 to convert them to hi-res jpeg to use in starstax, stacked them with the free program starstax (which is awesome), put saved file back in LR4 for very minor tweaking. upload to flickr, took about an hour to do both photos.

    hope this helps someone, and would love to know how others do their trails

    Nice shots, but the purpose of the thread was to see any attempts with the E-M1, as noted in the title.

    Personally, I've come to the conclusion the E-M1 simply can't perform anywhere near the level I expected it to at night. I had an E-M5 and thought I would be stepping up when I purchased the E-M1 right after it was released, but I should have waited to see the tests and reviews. By day it's an excellent camera that I'm very impressed with, but at night it's been a big noisy leap backwards. As a result my E-M1 will be available in the for sale section soon.

    I am surprised. DPReview said the E-M1 had "slightly lower measured noise than the E-M5." And shooting star trails you can use lower ISOs anyway.

    Regular exposure noise may be negligibly better on the E-M1, but dark noise is measurably worse.

    Yeah, and I think much of this is due to the differences in sensors. I'm super impressed how well the Sony sensor does with long exposure and dark noise.

    Yup, I like what's coming out of the E-M5 and E-M10.

    I think Olympus should be embarrassed over the long exposure performance of the E-M1 and it's Panasonic sensor considering this is supposed to be their flagship model. Also, this isn't just a problem for night photographers. If you try using a 10-stop filter for long daytime exposures (like I've tried with the Hitech 10-stop filter), you run into the same noise problem.

    The link posted by dhazeghi sums it up the noise problem very well.

    Also, the firmware patch we received a couple months ago helped improve things when shooting with dark frame subtraction enabled (called Long Exposure Noise Reduction by Olympus), but even with this enabled on the latest firmware it still gets very noisy if you want to shoot for more than about 30 to 40 seconds at any iso.

    Can someone explain the dark frames for noise subtraction? I understand stacking but not the dark frames.

    Here's one I shot back in March with the E-M1 and the 12-40mm f2.8

    ISO 400
