    Default Web Cam Choice?



    All--

    I am so stunned by corpusse's incredible Jupiter images that I think I will try my hand at web cam imaging.

    I FORGOT I have this wireless web cam; a Swann Security Night Hawk that I bought for a robotics application and have not used. How can I tell if it is appropriate?

    Preferably, I would start with something that could provide good results if I do my part.

    Thanks!

    You will want something that responds to the exposure settings that the software demands of it.

    The nice thing about the NexImage is that it is actually a CCD chip instead of a CMOS like many webcams, and it can be driven at various exposure durations. I don't know if the camera you've got will work like this.

    You might try taking a look at the capture software, wxAstroCapture, or the AMCap utility that Celestron furnishes with the NexImage.

    I think I'd try the webcam with the wxAstroCapture, and see if you can get long and short exposures with it. If so, then ... why not try it on the Moon??

    Sweet looking Camera

    Minimum Illumination 0 Lux

    That is pretty good, my little webcam has a rateing of 1 lux. The lower the number the more sensitive it is to light. So it may do o.k.

    Remove the lens, and pop on an adapter, or a 35mm film container and see what it can do.

    It is pretty sensitive, but only has 380 lines so the resolution may be poor.

    My recent saturn shots were done with a 640X480 camera (Philips got for about $60 including adapter) and I am not too happy about the resolution.

    Have you looked into using video from your DSLR? Also there are cheap webcams to be had like the HD Microsoft cam at 720p for $60 or so in the USA, that you can use to make very good shots, or just go for the autoguider/imaging solution with Orion Starshoot Autoguider & Planetary Imager.

    Bill have you decided which cam you will be using?
