    Default video camera to laptop



    Hello to you all out there--anybody able to offer advice on best/easiest whatever means of viewing on laptop via a video camera? Mind you, in this "wettest since records began...." year, it makes you begin to wonder whether decent viewing will ever come round again! Still, hope springs eternal in the human breast, as the optimist wrote, so I shall await those lovely clear, frosty nights.dome.JPG

    You might want to tell us exactly which video camera you will be using. Most require that you get a "video capture device" which is also often somewhat less accurately referred to as a "video grabber". But there are others which are not used that way so we really need to know which video camera is to be used.

    All video cameras will require a frame grabber. If it ain't got NTSC or PAL out, it's really not a vidcam.

    What do I use? There are cheaper solutions, but the best I've found is the Dazzle, which is easy to get on Amazon.

    I'm curious. Would you then not consider the Celestron or ZWO cameras to be video cameras? I will confess to thinking that they are, but I'm really interested in hearing what someone with far more experience and knowledge in that area might think about that.

    Now you've confused it! I assume, then, that a "grabber" is a separate component to the vidcam?

    knowing my ignorance on this are they not glorified Web cams ? if they are then they will need grabbing software such as Astro Capture , which i downloaded last night and it works very well and has a nice long exposure tab as well

    It sort of depends on what kind of camera you are using.

    The dedicated astronomical video cameras typically have an analog output and are not webcam-type and require a video capture device. This means they need some sort of video capture device.

    Webcams are different.

    I think that the Celestron Skyris series may have built-in video capture hardware and thus does not need a separate video capture device. There is another camera which may soon start shipping which may have the video capture hardware sort of built into the system as well but with the option of pulling the analog signal out of it and skipping the video capture hardware.

    There is no governing body that makes definitions for us to use in our hobby. What is and is not a video camera is the subject of debate.

    However, within the video astronomy community, the term video camera typically refers to a camera with an analog video output to either the NTSC or PAL standard.

    There is no reason to use a computer in order to use a video camera with a telescope as they will plug directly into the AVin of a TV, TV monitor, DVD player, CamCorder, etc. A computer is needed if you want to do some imaging, broadcasting, etc. I have a small 7 inch LCD monitor (PAL) on order for my video camera. Very lightweight and portable and fugal power requirements. However, at the moment I use a laptop as my portable DVD player bit the dust.

    Well, so far as using a computer being a need?

    It all depends on how you want to use it. Check out the AstroLive Box: AstroLive Box – Astro Precision Instruments Use the thing to control your mount, your camera, and broadcast the camera output to a tablet while you are inside or outside. A future update will likely allow you to be at a star party and let other people access the imagery from the camera/Astrolive Box on their own computer/tablet/phone while you control the mount and camera from your own computer/tablet/phone.

    Things are getting less clearly defined and more opportunities are arising.

    Oh, and I got my copy of "Astrophotography on the Go" and it looks really good so far! Obviously written by a smart and intelligent author. The editors missed some stuff but it doesn't detract from the overall value. Good book and I'm glad I got it.

    So you plug the webcam into the dazzle and create the video from that?
