Focusing is easy because my Newtonian’s diffraction spikes split into two parallel lines when the image is slightly out of focus. To view this digimag, Adobe Flash player is required. This data is also recorded against dark frames whenever they are generated. Altair Hypercam M V2 mono astronomy imaging camera. You can download it here. 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.

The introduction of Meade’s inexpensive line of CCD cameras for astro-imaging was no surprise. So what got me interested? This data is also recorded against dark frames whenever they are generated.
Envisage is a clever program geared towards getting you the best image possible. A detailed s exposure of M27, but without a software fix the raw image suffers from too much noise.
Messing Around with Meade’s DSI-Pro
However, for monochrome imaging meaed DSI-Pro does well enough to be fun to mess around with. Maybe I was a little jealous, or maybe just plain curious, but I had to see what Meade had accomplished. The DSI-Pro, running at outdoor temperatures, throws away most of that advantage, but not all of it. After a lot of experimenting, I gave up using the Meade software for anything but capturing the raw images.
Altair Hypercam M V2 mono astronomy imaging camera. Post-stack processing with these images was minimal; I used the Brightness Scaling Tool with Sigmoid scaling, and touched up the final contrast before exporting the images you see here.
I set it for 2x resampling and let AIP4Win stack the image series. Find out where to buy your equipment with our Retailer Guide.
This review appeared in the January issue of Sky at Night Magazine. 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.
Deep Sky Imager (DSI) IV / Telescopes, Solar Telescopes, Binoculars, Spotting Scopes
Bresser full HD deep-sky camera. And market-oriented companies like Meade know their customers: I can honestly say that it was a bear to install and a pain in the butt to operate. Then I lock the focus, close down Magnifier, increase the exposure to 2 seconds, move to my target, and center it. Return to Richard Berry’s Home Page.
He mentioned that the venerable Cookbook camera had been an inspiration for the DSI series. The color rendition in the images was terrible. A sensor inside the camera takes the temperature of the chip and displays the data on your computer screen. When I got my observatory fully operational early in summerI shot the four images that follow.
Meade Deep Sky Imager Fan – for all Meade DSI models
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. I use Meade’s Envision software to capture the image sequences. Scott related how he had seen the Cookbook, and was impressed at the speedy image display and overall ease of use.
The field of view was microscopic. But once in a while everything worked, and images actually popped up on the computer screen. To view this digimag, Adobe Flash player is required. In my experiments, the Meade software wasted a lot of usable exposures.
Deep Sky Imager IV (DSI-IV)
In summer, Meade’s software does a good job dark-subtracting second exposures and less well with second exposures. This improves image resolution, increases the image dimensions and acts as a field de-rotator, as long as your telescope is controlled by AutoStar. Meade had upgraded the software somewhat.
