He sent it to me. I use Meade’s Envision software to capture the image sequences. Watch the latest episode on BBC iPlayer. He got it to work but gave up on it as a serious CCD camera. However, long exposures showed that the noise was evenly distributed across the image with no unwanted gradients. I can honestly say that it was a bear to install and a pain in the butt to operate. The software was buggy and froze up.

Deep Sky Imager IV (DSI-IV)
But once in a while everything worked, and images actually popped up on the computer screen. The software is coded in VS. Return to Dsii Berry’s Home Page.
The field of view was microscopic. However, long exposures showed that the noise was evenly distributed across the image with no unwanted gradients. This improves image resolution, increases the image dimensions and acts as a field de-rotator, as long as your telescope is controlled by AutoStar.
Dsii use Meade’s Envision software to capture the image sequences. In winter, when it’s cooler, the longer exposures might be superior. In my experiments, the Meade software wasted a lot of usable exposures. This data is also recorded against dark frames whenever they are generated.

This proved to be true: Testing showed that Meade’s dark-subtraction did a pretty good job, and if I set it so that the capture 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.

A detailed s exposure of M27, but without a software fix the raw image suffers from too much noise. So what got me interested?
Our main concern was the base level of noise mmeade generated. If you already have an AutoStar-controlled telescope, the DSI Pro II should be a serious consideration; the level of integration between software, camera and scope is excellent. To view this digimag, Adobe Flash player is required.
I then use MicroSoft’s Magnifier program to blow up the image really big on the screen.
Bresser full HD deep-sky camera. Meade had upgraded the software somewhat.
The DSI-Pro, running at outdoor temperatures, throws ,eade most of that advantage, but not all of it. The sensitivity of the camera was terrible. Envisage is a clever program geared towards getting you the best image possible. And market-oriented companies like Meade know their customers: 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.
I put the camera into auto mode with a 0.

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 dxi minutes while 20 to 40 images accumulate. 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.
Scott related how he had seen the Cookbook, and was impressed at the speedy image display and overall ease of use. You can opt-out at any time. Adding filters will reduce the amount of light reaching the chip, so dark current and readout noise will inevitably lead to either considerably longer exposures or much noisier images, which seems to me like a lose-lose situation.
The software was buggy and froze up. The color rendition in the images was terrible. Altair Hypercam M V2 mono astronomy imaging camera.
