Hi Ken. On my computer Envisage had created folders C:\Meade Images and \Darks automatically. I’m running Win XP Home edition.
The only things that I can think of that stop files from being saved:
Your DSI camera (colour) requires some different setting then my (mono) DSI Pro
Your computer has some other program installed on it that prevents Envisage saving files in specified folder.
Your commuter got some sort of hardware problem.
What I would do in your situation is to take ten 1second exposures with default name ( Deep Sky). When you click “Stop” you should see DeepSky1 (or 2,3,4…..) Tab on top of the image in the left corner. If you see Deep Sky1, well it is most likely that other images you took before are not anywhere on your computer. But if you see Deep Sky2 or higher number, your previous images should be somewhere on your computer.
Exit Envisage and use Window Explorer to look in default folder if the Deep Sky1 file is there. If it is not there, in Window Explorer click on “Search” , type Deep Sky1, Local Disc C: and let it search. If nothing is found – it has to be problem with your computer because Envisage is working on others people’s computers.
Well, have look in your Images folder if the Deep Sky5 is there. If it is there try couple more images DeepSky 6, 7 and see if they are saved. If they are saved, all is good and you are on your way to take more of great images.
At least you can see Octans on a clear night - the light pollution is so bad here seeing Octans to use it for polar alignment is a dream...
Stephen, not only can I see Octans easily, I also see the South Pole Star easily thru my Andrews 'Give Away' $10 Binoculars. Makes polar alignment simple.
This is the South Polar Star I use:

Ken it looks like we are going to have some fun sorting this out at snake valley if you dont have it sorted out by then
Martin, I'm not dragging all this gear to camp. You'll have to come down here and help (a whole 2.5k from camp)

Yes, they should if you check Dark Sub box. But, if the CCD temperature differs 5 degrees C from the temperature under which Darks were taken, Envisage will try to find set of Darks taken with temperature in that range. What will happen if it doesn’t find it, I don’t know. I may stop subtracting Darks.
Ken, my previous post about Darks and temperature is wrong. It doesn’t work that way. But I just deleted all my Darks and made new set and they are in Meade Images/Darks directory. Then I took some Lights with Darks subtraction on and yes, they seem to be brighter and noisier. But also really bad hot pixels are ether smaller or disappeared completely. I think that you need to use histogram to see how the image will turn up after processing. I will have to read bit more about this
Yeah, not easy. Just try this. Take pair of Light images with exactly same setting, except one image with Darks subtract and the other one without darks. Then adjust Histogram for the image taken with Darks Sub until all noise disappears. Then adjust the other image Histogram to same values. You will see the one taken without Darks still showing lot of noise.

I'll have to come up some time and enjoy your dark Snake Valley skies!
