Keith had been struggling to get EOS Movie Recorder to record the live view stream and set exposures correctly on his Canon. The programme has boxes to set shutter speed and ISO but they had no effect on the video. I tried last night and failed too. However, by reading the Canon manual the reason became obvious. By default live view is set to auto-exposure which is sensible but not what we want for the planets. There is a custom function menu setting called exposure simulation - this needs to be set to enable . The exposure/ISO settings will now control the live view pictures and you can get the exposure correct in the video.

The other quirk is that the avi codec used appears to require Registax6 to decode it - IRIS and Registax5 don't seem to like it.

Bill,
I looked up Live View in the index and checked each entry - one was for the exposure simulation mode. On the 40D it is set by Custom Function C,Fn IV-7 but I would expect it to be different on each model.

I tried this a few nights ago, though it gave an excellent field of view I struggled with settings like the gain

Personally I still think you can't beat the web cameras

I choose to image with an 11" SCT Celestron in this decade and do the other things, not because they are easy, but because they are hard......

Hi Dave

Think I have found it for the 600D it's the first option while in Movie Mode "Movie exposure" 2 settings Auto which looks like the default and Manual which is the one I have been looking for . When you select Manual the ISO and shutter speed are displayed but greyed out and by using the camera in the normal was you can change them Works in the office will give it a go next time we have clear skys

I can also choose time of the exposure or numbers of frames you want to capture.

Thanks for your help

Bill

Bill,
I would expect it to be under live view somewhere rather than the movie mode but I don't have a 600D manual.
Regarding Carl's comments. You stick in the mud! It really blows the old webcams away. It uses modern Canon low noise technology, it is USB2 and you also have a widefield view for locating the target. There is no gain to set just the shutter speed and the ISO. I would suggest 800 for the latter as this approximates 1 photon = 1 ADU, sometimes called unity gain.
Came across this DSLR (Sony) image of Saturn:

Hi Dave

I will check it out this evening, this hobby is keeping my brain active :lol:

Still looking for my second scope, it will mainly used for Galaxys and Nebular once I have the camera setting sorted, I also have a Opticstar PX-35C COOLAIR CCD for Planetary, Lunar & Solar imaging
Sensor: 1/4" Sony ICX098BQ CCD Colour
Sensor Resolution: 640(H) x 480(V)
Frame Rate: 30 FPS @ 640x480

What a great pic of Saturn

That' the same Sony CCD as our Philips webcams.

And regarding Carl being "stuck in the mud", I think that's unlikely in his Land Rover (broken down by the roadside maybe, but never stuck in the mud!) ;)

Well thats interesting the ccd is the same. Got mine when I bought the Sky-Watcher Skymax-127 and saved quite a bit.

Look foward to the next sessions on imaging as I can not get my head aroung the dfferent setting

Back to the 600D Ive been unable to fine anything in manual re the liveView setting, I will try a few Google search later

I finally managed some success this evening with my 1000d capturing the feed from the live view as an avi stream. I managed to capture a few thousand frames of jupiter and its moons and then turned to the moon and got another few thousand. It really is a great program, relativley simple (the one mentined by dave earlier in this thread) and works a treat.
however........ trying to load one of the avi files into registax takes forever ! if it manages it at all that is. Maybe its my computer but everything seems so slow ! Not even managed to get to the alignment stage on any yet. Am I supposed to do something to these files before loading them into registax ??
