    Favourite eea camera?

    Knowing that feeling Louise, I'm in the same boat as you,,, up the Clyde without a paddle lol, I'm four flights up and to try and get comprehensive kit out , with the poor weather were having,, is soul destroying,, Cooling on any camera is beneficial,, I modded Samsung scb2000 camera's and done a lot of testing years back and the amount of dropped frames was astonishing on non cooled mode to nearly none on cooling mod,, and that was only keeping the camera at ambient temperature..

    Total novice to this, but..

    Definitely go usb camera and laptop,, given what you would like,, this is the way you should look to go, Sensor's on the modern camera's are bigger and better than what was available during our time using analogue,, I don't think the analogue route would suit your needs or impress you,, zwo have probably the widest range of cameras available and there back up is good as well. And there are lots of folk using zwo camera's and tons of great information available, via forums, websites and Facebook pages.

    To dabble with analogue camera's,, I would check eBay out for a cheap scb2000,, I've bought one as low as £25,, but can easily still get to nearly £100. Bit of diy,, remove factory fitted ir filter,, fit a c to a 1.25 adapter,, and 12v power supply and your good to go,, if you like what you see then,, you could add a usb video Grabber and save images to a pc.. Very rarely do we hear of folk going back to analogue but it's good to hear,, video astronomy with latest kit and techniques are ,, just about,, astrophotography at times,, I just do what makes me happy and cross between both,,

    Good thing about video astronomy is you can go from diy to as expensive as you can afford,,also there are various techniques in doing it as well. The equipment and techniques are dependent on what you want to see. Going back a few years analogue was the weapon of choice and cctv cameras were adapted for astronomy use,, watec 902h camera's,, very sensitive,, used extensively for meteor capture,, one of the main work horses was and still used is the Samsung scb2000, it has a 1/3 sensor and integration to 512 ( exposure),, powered by 12v dc and by removing the factory fitted ir filter made a great video camera for astronomy, the Av feed could be put to a monitor or TV for live/ near live viewing,, the use of a usb video Grabber allowed the image to be recorded to a computer, the ln300 became more popular ,it was smaller and had double the integration 1024 this was the first camera in the revolution cameras range put together by mike at oc telescopes,, ken James ( dragonman) was a tester for the revolution cameras and has a few utube videos on them. Along came usb cameras and mallincam made some of the first to add to the highly successful mallincam analogue camera's like the exterminator and extreme,, Zwo has joined the many camera suppliers and do an extensive range,, Altair astro and many more, zwo has released the asi air that may be of interest,, it is a stand alone concept that can transmit images from its usb 3 camera's to tablets ect. Dslr camera's with live view can be used,, tethered to a laptop and using backyard eos or Nikon,, and stacking ect done via astrotoaster software,, A camfi WiFi control unit can wirelessly transmit live images from a dslr to a smartphone,tablet or pc. Hopefully some information may be relevant. Davy

    Comet 21p

    Nice capture
  9. Howie has done a few videos on the subject .
  10. Nothing wrong with using dslr camera's for video astronomy, there are folk using this approach on the other forums, cloudy nights and video astronomy forum and it doesn't create any problems with folk using dedicated video astronomy camera's, Dslr, with astrotoaster incorporating dss is a great way to go,, especially if you have one already,, As mentioned the forum is quiet,, mainly due to a lot of bad weather that seems worldwide to astronomers just now,so why spend money on a camera that may gather dust for a while,, Think we all have kit we need to sweep the cobweb's off just now. Even canon utilities used alongside astrotoaster is a good combo,, Howie from Australia has a put videos up on utube how to use it. Unfortunately he is leaving the hobby due to a back injury,, the numbers are dwindling but if we all keep helping each other great things can be achieved. Davy
  11. If you have a canon or Nikon DSLR with live view,, you could try this,, http://www.cam-fi.com/en/index.html

    EAA and live streaming

    Know how you feel,, most times I've went on ,, it's dead as a door nail,, only seen a few uninteresting tests during daylight hours. VAF had tried to get broadcasting via a third party in a joint venture,, but two years in,, it just wasn't going to happen,, which was unfortunate. I still believe the way forward is with Joe's nsn,, but it would need a few UK guy's to jump start it this side of the pond, to make it more UK friendly. Nsn CA is still going strong but more oriented towards mallincam users but still allow non mallincam users to broadcast I'm shure.

    Advice before my trip

    Hi Ben, I got the focal reducer/flatner for the reason s you state,, getting a better corrected flatter image, give me a slightly wider fov and gives a slightly faster scope as well,, ideal for wide field video astronom. I was using the high-tech astronomy usb focuser on my stock focuser but removed it for a while,, was putting it back on and had a seized shaft in the bearing,, I gave it a few taps with plastic hammer after soaking in wd40 oil, but it damaged the bearing and still didn't release,, the bearing isn't a full bearing,, only three balls,, not ideal. I replaced it with the ovl upgrade focuser and couldn't be happier,, like night and day comparison to stock focuser,, but had it not been damaged I probably wouldn't have changed it,, I never expected it to be so good.. Been a bit wary of fitting the hitecastro dc focuser as I haven't seen any posts of the skywatcher electric focuser being fitted to one so far. The hitecastro dc focuser is brilliant operated from the laptop, does a great job
