Will, The Sony sensor may not behave identically to the Kodak but the light frame was showing edge glow, which makes me think the dark should too, or it will not get removed. Of course we may be

I loaded up your earlier dark frame in TheSkyX FITS viewer, the attached image shows how to set TheSky's fits viewer for a reasonable display when capturing images. For my QSI683, 583 and 532 cameras

Zack, understood and good news. I will be raising that temp - this was a litmus test to make sure that the cooling was actually working. What is a good general rule for cooling? It gets really hot

You are now showing -24.7c and the dark is looking as expected for a 6120. All is well. The FITS header is still showing that your setpoint is -40c which you need to make sure it is set to something

I looked at the image after the STF Autostretch (Ctrl-A) Looks like approx 5 vertical bands and about 100 hot or warm pixels plus noise and a lighter band at the extreme top.

Thanks, William. I don't have Google Drive set up like that yet but will. Good info in the cooling. I have a 683WS with mechanical shutter and 6120WSG with mechanical shutter. And the dew cap is

Zack, when I go into TSX like just now tonight, this is what I've been seeing. Ambient is 20.55°C in the observatory.? This is the camera status that is displayed after about 3 minutes and taking

Kevin, As stated before, the stretched view of the image in TSX is not to be judged, as it will look bad. You need to properly look at the file to make a judgment about the sensor. In Pixinsight

Hi Paul. Just a FYI, the QSI 6120 has a Sony sensor and doesn't have the same edge glow and bias pattern that the Kodak KAF8300 shows. Will.

OK, please help me learn. I've been shooting film and digital for years but this is a whole new game for me. I never got serious with my used ST2000XM years ago. I was in South Carolina and was still

Kevin. For the temperature of the camera at exposure time the dark frame looks ok to me. A couple of points, the fan control in the QSI driver setup has user options, set to "Quiet" mode the cooling

Kevin, I am not seeing the edge glow that I normally see in a dark. (I use a QSI 583 and 683) and this makes me suspicious that it has been altered. Also, the temperature of the CCD is recorded as

If your ambient temp is 30c, that means you would only be able to get to a set point of -10c reliably, just something to note. Again, your FITS header is reporting that the CCD temp is +13.5. That is

It was 26°C outside and over 30°C in the dome, so cooling was working. Why isn't it dark? Thanks. Kevin

In the future, you just need to adjust sharing settings so that "anyone with link" can download/edit your file on google drive. Google drive will also send out emails that you approve request to allow

I tried to find a site, Will, but had no luck at the time. Try this: https://filebin.net/gb2bikm8bb5r25h1 It expires in 6 days. Thanks, Kevin

Hi Kevin. You need to post a link to your dark frame that is publicly shareable. The link you provided is a private link that requires the user to log-in to an existing GoogleDrive account, or

OK, took two darks tonight, both at -40°C below ambient, which was about -18°C.? Here is one of
