    Default ToupTek and ToupSky



    Hello Everyone!
    I'm new here and need a bit of help with my astrophotography. I have a Skywatcher Dobson Telescope N 355/1600 14 inch Skyliner FlexTube BD SynScan DOB GoTo and a ToupTek EXCCD00440KMA mono camera. Does anyone have experiance with this camera and its software (ToupSky)? The problem I am having is that the image is "noisy" and the software doesn't seem to have many options to clean it up. I also don't know how to take a video and save it for processing. My targets are DSOs. I would be very thankful for any help I can get on this matter. I mainly want to take exposures, process them quickly and display the image on a screen for astronomy outreach. Thank You!

    You have one of the "older" CCD cameras. Those CCD sensors are rather noisy and it is not surprising you are having issues.

    I've never used your camera and ToupSky (and you won't find many who have) but ToupSky is not considered by many to be great software. Just about the best for NRTV (Near Real Time Viewing) is probably the SharpCap.

    You'll probably want to do calibration frames (darks, flats, etc.) to help clean things up as much as you can.

    But I'd also make sure you have the latest drivers for your camera.

    I wish you luck!

    Thanks OleCuss for your speedy reply. I am sending my camera back and will get a better one. With my telescope, could you recommend a camera that I
    can use for live astronomy outreach?

    Thanks!

    That is actually a very tough question and I may not be able to do it justice in the limited time frame I've got so I'll apologize in advance.

    The quieter sensors are the newer CMOS types.

    Possibly the sensor with the best SNR currently available to people like you and me is the IMX224 made by Sony. Some very good cameras are made with that sensor.

    I'm not entirely sure, however, which telescope system you are using. I'm guessing it is this one: Sky-Watcher GoTo Collapsible Dobsonian 14″ (356 mm) – Sky-Watcher USA or one which is very similar - but the specifications are just a little different than what you listed for yours.

    But assuming it is that 14" Sky-Watcher I am not so sure I'd want to use the IMX224. With the long focal length of that 14" scope your FOV is going to be tiny which will make it hard to even find your target let alone track it nicely.

    So I'd be thinking of getting something like the ZWO ASI1600 or ASI071 - or the similar cameras from QHY. The bigger sensor means a better FOV although given a focal length of 1500mm the FOV will still be rather small. The SNR will not be as amazing as with the IMX224 cameras, but it is still pretty good.

    You'll want to study up on this stuff for a while before you get a new camera, however. You want to be sure it will do what you want and how you want.

    I'm actually tempted to try out something like the ASI071 with my XX12g this weekend. I think it would work quite well but I've yet to try it.
