I assume yours came with autostar suite IP ( processing software ) and Envisage ( capture software )
Assuming the above is correct,
Did you make sure to install the drivers on the supplied disc BEFORE plugging the camera in? Thats has to be done, after the initial driver installation is finished, then plug the DSI in and let the computer recgonize the device ( with the disc in the drive )
As for the image. Even a SLGHTLY out of focus image will appear as white and black specks and or lines. The image clears up the closer to focus. I dont use a hartman mask, I use a 25mm EP to find my target, then start up my drives to track it. Then SLOWLY start to focus the image you will begin to see any brighter stars as fuzzy blobs, keep going untill they are as tight as you want them. Bright stars will typicall show difraction spikes, which I use to make sure I am focused properly. The fine point on the spikes gives you a good idea of being pretty darn close to perfect.
Now, keep the contrast and shadow on auto, selected on the right, and up on the top left click on LIVE. to set YOU exposure time check the box ( near the top left ) and set it to where you want.
Now go over to the top right and click on Save Proc,,,I work with Fits, which IMHO is best. Choose them, IF and only IF you have a post processing tool that can handle it. IP can,,,but if you want to use anything else fits dont play well with a lot of programs. CS2 does with a free plugin called Fits Liberator. And also after selecting Fits. click on " save all uncombined images "
There is a folder on your c:drive/meade images. This is where all your images will be saved ( including darks, which I take either half way through or at the end of a session ). click on start, and it will start taking pictures. Ater the first shot, three tabs will be available where you WERE looking at the image display. Click back on the DSI, so you see the real time image as each exposure clicks off. Stop when you feel you have captured enough. and open up Envisage to dark frame calibrate, 1 star align ( use a central star ) and then do a group median combine.
Any more questions, I will try to help.
