In winter, when it’s cooler, the longer exposures might be superior. This proved to be true: This review appeared in the January issue of Sky at Night Magazine.

And market-oriented companies like Meade know their customers: I set it meads 2x resampling and let AIP4Win stack the image series. Watch the latest episode on BBC iPlayer. This data is also recorded against dark frames whenever they are 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.

In winter, when it’s cooler, the longer exposures might be superior. Bresser full HD deep-sky camera. In my experiments, the Meade software wasted a lot of usable exposures. You can download it here. He sent it to me. 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.
Our main concern was the base level of noise it generated.

Deep Sky Imager (DSI) IV
The aluminum housing is crudely cast and minimally machined. Focusing is easy because my Newtonian’s diffraction spikes split into two parallel lines when the image is slightly out of focus.
Although this works well and the DSI meare fairly low heat-induced noise, it still produces noisy raw pre-processed images.

Messing Around with Meade’s DSI-Pro
This is a stack of 74 exposures each 15 seconds long, with no tracking or guiding. He got it to work but gave up on it as a serious CCD camera. I put the camera into auto mode with a 0. When I got made observatory fully operational early in summerI shot the four images that follow. But once in a while everything worked, and images actually popped up on the computer screen. Cookies perform functions like recognising you each time you visit and delivering advertising messages that are relevant to you.
I can honestly say that it was csi bear to install and a pain in the butt to operate. He mentioned that the venerable Cookbook camera had been an inspiration for the Mezde series.
I had to reinstall the Mexde 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. You can opt-out at any time. In summer, Meade’s software does a good job dark-subtracting second exposures and less well with second exposures. Meade had upgraded the software somewhat.
Then I lock the focus, close down Magnifier, increase the exposure to 2 seconds, move to my target, and center it. However, for monochrome imaging the DSI-Pro does well enough to be fun to mess around with.
Then, when you take an image, Envisage looks for the dark frame with the closest temperature match and subtracts it automatically to get rid of the noise — a really nice touch.
The Ring Nebula picture was taken in dis fall of from my half-completed observatory. This improves image rsi, increases the image dimensions and acts as a field de-rotator, as long as your telescope is controlled by AutoStar. 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.
