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. However, for monochrome imaging the DSI-Pro does well enough to be fun to mess around with. So what got me interested? In my experiments, the Meade software wasted a lot of usable exposures. Meade had upgraded the software somewhat.

A sensor inside the camera takes the temperature of the chip and displays the data on your computer screen.
This proved to be true: I haven’t tried to make color images with this camera. And market-oriented companies like Meade know their customers: You can opt-out at any time. Meade had upgraded the software somewhat. This improves image resolution, increases the image dimensions and acts as a field de-rotator, as long as your telescope is controlled by AutoStar.
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.
Stargazing breaks in the UK. 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.
Altair Hypercam M V2 mono astronomy imaging camera. The introduction of Meade’s inexpensive line of CCD cameras for astro-imaging was no surprise. Focusing is easy because my Newtonian’s diffraction spikes split into two parallel lines when the image is slightly out of focus. He got it to work but gave up on it as a serious CCD camera. After a lot of experimenting, I gave up using the Meade software for anything but capturing the raw images.
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. Adding filters will reduce the amount of light reaching the chip, so dark current and readout noise will inevitably lead to either dwi longer exposures or much noisier images, which seems to me like dsj lose-lose situation.
The DSI-Pro, running at outdoor temperatures, throws away most of that advantage, but not all of it.
Deep Sky Imager (DSI) IV
Scott related how he had seen the Cookbook, and was impressed mrade the speedy image display and overall ease of use. Our main concern was the base level of noise it generated. AutoStar Suite has everything you need to plan, capture and process your images. Jim tried it first.

You can download it here. When I got my observatory fully operational early in summerI shot the four images that follow.
In my experiments, the Meade software wasted a lot of usable exposures. Cookies perform functions like recognising you each time you visit and delivering advertising messages that are relevant to you. Watch the latest episode on BBC iPlayer. The software is coded in VS. I set it for 2x resampling and let AIP4Win stack the image series. 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.
I use Meade’s Envision software to capture the image sequences. The color rendition in the images was terrible. This is a stack of 74 exposures each 15 seconds long, with no tracking or guiding. I put the camera into auto mode with a 0. 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.
The software was buggy and froze up.
