Hi Robin, I´ve downloaded the latest version of 4.0 beta today and realized that you have allready changed the WB für QHY 268-C to 10 during the sensor analyses. Thanks for the quick response on this issue I have done a measurement of mode #3 Extend Fullwell 2CMSIT (yellow curve) and the result is n...

Ok I will Check ist with Extended Fullwell Mode…. In Highgain mode with gain = 0 the diagram of QHY (blue line) shows a System Gain of 1 e/ADU (unity) and a FWD of 62 ke - my last results with WB=10 at gain=0 were 20% lower - doń`t know if I have to worry about it, but in my opinion the difference i...

Here are my results, I´ve never got a picture like yours with one white peak on the right side ;((( I couldn´t adjust the WB below 10 in each chanel Sensoranalyse QHY 268 C.pdf Afterwards I´ve made a sensor analysis in HG Mode with a WB of 10 in all channels - seeems to be a better result, but I sti...

Thank you for all your efforts and explanations .... in the end we unfortunately still have no clear idea why the QHY measured values of the 268-C ​​in the official diagrams for System Gain and Fulwell deviate so significantly from the sensor analysis in SharpCap, while the values ​​for readout nois...

Hi Robin, I´ve got still the same results, nothing changed (Systemgain and Fullwell are at 50%). I´ve adjusted the WB as you can check in the picture below. The sensor analysis starts automatically with a WB of 15 for each chanel, but with this there is a huge differenz between the the curves of red...

Thanks Robin, just one more question before starting the test at the weekend again. When I have detected these special WB values for R/G/B in overexposure, I have to write them down. That´s important, because after pressing START for the sensor analysis, all values are set back to a standard and equ...

Hi, I´m not really sure if I´ve understood your advice regarding the colour balance right. I tested it with the figures you find attached. With these levels the red, green and blue curve are at the same level. The result was a little higher system gain, but a lower fulwell - but still far away from ...

Thanks Robin, Yes I‘ve checked it also in the modes DSO and Ext. Fullwell Same result , approx. 50% of System Gain and Fullwell data in comparison to the QHY diagramms. But Readout Noise and Dynamic Range are 100% ok I will check and test the colour balance and come back with the results Have a nice...

Hi Robin, can´t wait for it and tested it allready in 4.0 beta - same result, System Gain and Fullwell are about at 50% of the value that QHY delivers on their homepage. See snapshots attached As you are a Top-Partner of QHY , would ypu please adress this issue. It could be very helpful for the user...

Thanks Robin, I will test ist soon

Have a nice weekend
