Scott related how he had seen the Cookbook, and was impressed at the speedy image display and overall ease of use. This proved to be true: Then I lock the focus, close down Magnifier, increase the exposure to 2 seconds, move to my target, and center it. I put the camera into auto mode with a 0. I haven’t tried to make color images with this camera. Focusing is easy because my Newtonian’s diffraction spikes split into two parallel lines when the image is slightly out of focus.
Maybe I was a little jealous, or maybe just plain curious, but I camra to see what Meade had accomplished.
Messing Around with Meade’s DSI-Pro
So what got me interested? The aluminum housing is crudely cast and minimally machined. Return to Richard Berry’s Home Page.
In winter, when it’s cooler, the longer exposures might be superior. I make sure that I’ve got the right filename set up, check the dark-subtract box, verify that it’s set to save all images, reset the long exposure time to 30 seconds, and then leave everything alone for 10 to 20 minutes while 20 to 40 images accumulate. This is a stack of 74 exposures each 15 seconds long, with no tracking or guiding. The software was buggy and froze up. The introduction of Meade’s inexpensive line of CCD cameras for astro-imaging was no surprise.
Although their initial attempts to enter the amateur CCD market were flops, it was unlikely that this aggressive company would sit by while others cashed in on anything to do with astronomy. Vamera showed that Meade’s dark-subtraction did a pretty good job, and if I set it so that the camerx program would save every image in the FITS format, I could stack the images using AIP4Win to get what I consider better results than Meade’s software delivers.
When I got my observatory fully operational early in summerI shot the four images that follow. I had to reinstall the USB drivers over and over, and even then it seemed to be hit-or-miss whether my laptop would recognize the DSI when I plugged it in.
I then use MicroSoft’s Magnifier program to blow up the image really big on the screen. Meade had upgraded the software somewhat.
The DSI-Pro, running at outdoor temperatures, throws away most of that advantage, but not all of it. When the DSI-Pro was announced, we briefly considered writing a book for new users who were sure to find imaging with these low-end cameras daunting — so I “invested” in a DSI-Pro. He got it to work but gave up on it as a serious CCD camera. The color rendition in the images was terrible. After a lot of experimenting, I gave up using the Meade software for anything but capturing the raw images. I use Meade’s Envision software to capture the image sequences.
In my experiments, the Meade software wasted a lot of usable exposures. He mentioned that the venerable Cookbook camera had been an inspiration ds the DSI series. In summer, Meade’s software does a good job dark-subtracting second exposures and less well with second exposures.

But once in a ccamera everything worked, and images actually popped up on the computer screen. I can honestly say that it was a bear to install and a pain in the butt to operate. Jim tried it first. The software is coded in VS. However, for monochrome imaging the DSI-Pro does well enough to be fun to mess around with.
On a cool night you can expose for several minutes.
