    I have been thinking of really testing the E-M10.
    Got a used one and did the try out last night.

    I think it is promising, did some mistake, I ran out of battering wile doing my dark frames.

    I shot NGC7000 (North America nebula) to see how the red would come out before the modification.
    This is 21 exposure of 300sec at ISO 1600 with a Explore Scientific 102mm ED triplet with a 0.8x focal reducer and an Astronomik light pollution filter ... 6 dark frames, 10 flat frames and 100 BIAS frames all process in Pixinsight.

    It not pretty, I didn't do all the best practices, it is more a test...

    Next step is to modify the camera to full spectrum and see...

    I call bullshit, because that picture is beautiful. :)

    21 x 5 min? So total time was 105 min?

    @RenaudVL@RenaudVL - I don't always check every forum, and because of that I tend to miss out on stuff like this. What an awesome picture. I have now watched the entire Astrophotography forum to make sure I don't miss out on these kinds of threads.

    Great work, and please continue to post.

    I can't see an image or a link to his gallery,
    but I did read that paragraph of arcane mystery and understood it not at all.

    repost piccie?

    Thanks every one,
    I have abandoned my plan of modifying the EM10 for lack of support from Olympus Capture.
    I need that feature to really test it in my observatory. I will do more test with my O-MD E-M5 II.
    It would to be long to explain in detail on why I need remote capture, lets just say that for achieving best result I need to do dithering (moving the telescope by a few pixel between each exposures) and since no real astronomy software support Olympus it leaves me with the no options for now.
    Of coarse these camera can achieve great result but this same target wit a modify Canon looks like this...
    Taken with the exact same telescope, you will notice also the smaller sensor crop the field of view quite a bit...

    Can dithering be achieved with the hires mode on the E-M5 II?
    (Instead of moving the scope?)

    Also, doesn't the earth move fast enough if you wait a few secs between exposures?
