Return to Richard Berry’s Home Page. Bresser full HD deep-sky camera. 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. Stargazing breaks in the UK. Let me finish off by saying this; who needs lro spend thousands of dollars on an imager with cooling when there is a perfect all around imager on the market for the beginner or advanced imaging person at a truly great price??
Envisage is a clever program geared towards getting you the best image possible. He sent it to me. When dark subtracting the software not only uses the exposure length but also uses the temperature of the exposure giving you the best dark frame subtraction possible.

How does the CCD Temperature dsii work? Jim tried it first. For most processes, these applications should still work correctly unless they are calling any specific functions that may have changed.
I think Meade Can market their equipment with out my help. You can also specify the tolerance of the temperature differential of the dark frame subtract from exact temperature to 1,2 3,4 C tolerances. 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.
Meade had upgraded the software somewhat. 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. Then I lock the focus, close down Magnifier, increase the exposure to 2 seconds, move to my target, and center it.
Adding filters will reduce the amount meeade 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.

Since no squaring of the pixels is performed, the resultant images are still x pixels. However, long exposures showed that the noise was evenly distributed across the image with no unwanted gradients.
However, for monochrome imaging the DSI-Pro does well enough to be fun to mess around with. No, the cameras are cooled via thermal convection in the same manner as previous DSI’s.

If possible, USB 2. Let me first start off by saying thanks Meade for allowing me the honor of helping out with the new imager. For me one word; WoW!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I then use MicroSoft’s Magnifier program to blow up the image really big on the screen. I make sure that I’ve got the right filename set up, check the dark-subtract box, verify that it’s set to iii 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 summer, Meade’s software does a good job dark-subtracting second exposures meace less well with second exposures. When taking dark frames, the software now saves each dark frame with not only the exposure time selected, but also the temperature of the camera at the time of the exposure.
This improves image resolution, increases the image dimensions and acts ki a field de-rotator, as long as your telescope is controlled by AutoStar.
