It's been a good two years since I posted here. I'm ashamed to  admit I forgot I created the blog. That's not to say I have abandoned the DSI-II. For some reason I no longer remember I stopped posting. Time to give it a renewed try. For the near future posts will catch up on past activities.

Meade no longer produces the DSI-II. There was a DSI-III which has been discontinued along with the full DSI line. In fact I was "lucky" to grab mine for a substantial discount as Meade was closing out the IIs. I put lucky in quotes because the DSI-II is a mixed blessing. It was cheap $290. It does work as you can see from the earlier images.

With its automatic dark frame subtraction it is easy to use. On the other hand the product is really poorly documented and the software interface is poorly designed. Meade left it to an enthusiast to create a video tutorial that is not done under the dark but none the less is more informative than the included documentation. The documentation does little to explain how to use the various settings or what many of them mean. This has been a recent pattern with Meade. The documentation for its Autostar

Whoever coded the software interface did not account for varying screen resolution. Thus the user must futz around with screen resolution settings on a high resolution laptop just to get a usable screen. The lack of temperature regulation is another source of frustration on nights when temperatures constantly change. One is forced to keep generating new sets of dark frames as the device cools along with the night air. A few users have modded their DSI-II with Peltier cooling. I'm not yet brave enough to try that.
