Hi!

I'm new to astrophotography and I just purchased an ASI585MC Pro to start shooting. However, I'm not getting any images on my laptop or ASIair Mini. All I see is a white image, and sometimes another single color, but never a proper image.

    Reduce the exposure time and camera gain. Check the "mean ADU" in your program. If the mean ADU is over 65000, you are overexposing.

    If you are testing in the daytime, use the shortest exposure time that is available to you (usually around 1ms to 32ms). And, with ZWO cameras ("gain" is in 0.1 dB), set the gain to zero.

    Even that can overexpose the camera. If so, you would need some ND filters to play in the daytime.

        zY3sp3Z6 When I set the gain to 0 I obtain that :

        Yep, notice that with low gain and very short exposures, your histogram is all the way to the left. Start increasing exposure time slowly until the histogram peaks at the middle.

        Test it during the daytime first. I know you don't care about daytime, but believe me, do it. It is the only way to get near to correct focus. Otherwise the stars will be spread over too many pixels, and you will never see them. Aim for the largest object you can find during the daytime -- I have even used clouds to focus with.

            w7ay Okay thanks It's work I think
            Maby I have no image because I test the camera without the telescop and without obhectifs

              hi, were you able to get an image? I'm in the same boat, even with the camera connected to the telescope with a flattener and all the extension rings needed to reach 55mm.

                Lilia Could you please take a pic of your connection way? and what is the model of your telescope.
                If you would share some images may be helpful.

                    Tech@ZWO Hi sorry for the late answer actualy I try just to see any image with my camera without my telescop

                        zY3sp3Z6 It is different from DSLR or other cameras, because it has only the sensor, does not have the lens, so the view can not be projected onto the sensor, you also need the telescope for photography.

                            Tech@ZWO Oh okay, that’s why I’m not getting an image then? Thank you very much I will try again this evening then with my telescope

                                zY3sp3Z6 Yes, please feel free to contact us if there is any questions.
