DSI III Darks, Envisage vs. Nebulosity

Hello all,
I recently read a few threads concerning the Amp Glow of the DSI III cameras. I have the DSI III Pro and was very aware of the Amp Glow and it did concern me even though the dark frame pretty well eliminated it.

Then Craig from Stark Labs gave a lengthy explanation of the consequences of the Amp Glow and how his program Nebulosity had eliminated it by writing new drivers and program code for the DSI III.

Well, I decided that his program at $45 would be a pretty good deal if it did what he claimed, so I downloaded the free trial software and applied the upgrades. Then I took a couple of identical darks, one with Envisage and one with Nebulosity to compare them.

To my surprise, the Amp Glow was completely gone from the dark and the dark looked quite normal compared to other cameras, where before the dark was strangely lacking hot pixels and was filled with Amp Glow.

I will post each dark frame each taken at 13.5c CCD temperature and 339 seconds exposure time. The first is the Envisage dark frame.

This photo is the Nebulosity dark frame.

You can quickly see that the difference between them is striking. The Envisage dark has the Amp Glow (which increases with exposure time) and the hot pixels are very faint.

The Nebulosity dark on the other hand has the normal hot pixels seen on say an S-Big or other brand of camera.
