Altair Hypercam M V2 mono astronomy imaging camera. A sensor inside the camera takes the temperature of the chip and displays the data on your computer screen. In winter, when it’s cooler, the longer exposures might be superior. Although this works well and the DSI exhibits fairly low heat-induced noise, it still produces noisy raw pre-processed images. He mentioned that the venerable Cookbook camera had been an inspiration for the DSI series. I use Meade’s Envision software to capture the image sequences.

The field of view was microscopic. I then use MicroSoft’s Magnifier program to blow up the image really big on the screen.

Stargazing breaks in the UK. A detailed s exposure of M27, but without a software fix the raw image suffers from too much noise.

This proved to be meadee Bresser full HD deep-sky camera. The aluminum housing is crudely cast and minimally machined. The color rendition in the images was terrible.
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. After a lot of experimenting, I gave up using the Meade software for anything but capturing the raw images.
Watch the latest episode on BBC iPlayer. This data is also recorded against dark frames whenever they are generated. 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.
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 dsk the FITS format, I could stack the images using AIP4Win to get what I consider better results than Meade’s software delivers.
Deep Sky Imager (DSI) IV
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. To view this digimag, Dso Flash player is required.
The Ring Nebula picture was taken in the fall of from my half-completed observatory. 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. In my experiments, the Meade software wasted a lot of usable exposures.
Messing Around with Meade’s DSI-Pro
Our main concern was the base level of noise it generated. 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.
Cookies perform functions like recognising you each time you visit and delivering advertising messages that are relevant to you. This is a stack of 74 exposures each 15 seconds long, with no tracking or guiding.
Return to Richard Berry’s Home Page. The introduction of Meade’s inexpensive line of CCD cameras for astro-imaging was no surprise. 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.
He got it to work but gave up on it as a serious CCD camera. Meade had upgraded the software somewhat. This review appeared in the January issue of Sky at Night Magazine.
Scott related how he had seen the Cookbook, and was impressed at the speedy image display and overall ease of use. Find out where to buy your equipment with our Retailer Guide. Focusing is easy because my Newtonian’s diffraction spikes split into two parallel lines when the image is slightly out of focus.
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.
