Re: Drastic drop in FPS

I had a similar problem that turned out to be for a trivial reason. I was using Dropbox and my home network eventually couldn't keep up with the uploads. I now pause the sync to Dropbox when capturing images.

The other night, I used the brain function to calculate optimal exposure near three different targets, and each time it generated exactly the same numbers. Is this typical, that sky glow doesn't vary on the same night (all three objects were in the same sky quadrant). I had previously done the senso...

Sensor analysis values vs. manufacturer specs

I did a sensor analysis on my ZWO ASI385, and it came out very similar to the data at the ZWO website. The differences were <10%. So I have two questions: Are deviations of <10% significant, i.e., will they have a noticeable effect on smart histogram functions? In the absence of doing a sensor analy...
