Re: Setting up master dark libraries
Thanks Robin. Quote: "It's best however to make sure that the brightness/offset in the darks is *lower* to avoid getting negative results when subtracting. Set the brightness/offset just high enough to ensure that the histogram is not touching the left hand side of the graph. " So from thi...

Re: Setting up master dark libraries
Thank you for the input. I do use the brightness setting as applicable to ZWO cameras (offset or black level in others) to position the curve in the histogram so it begins just to the right of the left edge and this of course varies by the object. I was hoping that I could make up the dark library i...

Re: Setting up master dark libraries
That is my take too from reading the manual but I want to make sure by getting responses from those in the know. I want to make use of my cloudy days (and nights) by setting up a range of darks. I don't want to later find out that the darks are not correct if the color balance and brightness setting...

Setting up master dark libraries
Both of my cameras are cooled so I want to set up master dark libraries for both with Sharpcap 3.0 (what I use to do NRTV and saving of the images). I know the darks should be taken at the same resolution, color space (RAW 16 is what I use), gain, exposure and of course sensor temp as I will use to ...

Re: Artificial light source or natural for sensor analysis?
Thanks for the heads up about the issue of light flicker. I'm going to utilize my deep cycle battery that I use to power the mount and a 12 volt light which will eliminate the flicker issue from the man made light source. It's supposed to be cloudy again tonight so I'll at least be able to do this.

Re: Artificial light source or natural for sensor analysis?
Thanks Robin, keep up the fantastic work. I'm sure most users are as highly grateful as I am. That's one reason I went ahead and upgraded to pro.

LOL, I guess I was really tired when I wroth the first post. I meant to say incandescent light bulb not tungsten.

Artificial light source or natural for sensor analysis?
Just joined the forum and I'm pretty new to AP. In fact, I do what I consider a cross between NRTV and actual AP. I am not opposed to doing longer subs if it can bring out more detail but I don't do any real post processing to saved images, just some color adjustment and contrast/brightness fine tun...
