Re: QHY247C Offset Problem

I use offset of 40 because it is what I use for my QHY224C and QHY168C cameras. I selected 40 using this table: https://www.qhyccd.com/index.php?m=content&c=index&a=show&catid=31&id=199 Now I am seeing their starting Offset is 200 with the QHY247C I did not use that table last night, however, I did ...

QHY247C Offset Problem

Robin, I am helping a friend with his new camera, and we are coming across a problem with the offset. When I set it to 40, the image is gray and the histogram is at 40%. I attached the logs for you. Connecting the camera through ASCOM does not show this problem. Do you know what is happening? Eric

Re: QHY168C Problems-Changing ROI Changes Gain and White Balance

Robin, I downloaded and installed the lastest SDK and Sharpcap and the problem still persists, though not as frequent. I try to not set the cooler to 100% if there is a large temperature difference between ambient and sensor. Rather be safe than sorry, and QHY mentions it in their manuals. The stran...

Re: QHY168C Problems-Changing ROI Changes Gain and White Balance

Robin, When I First turn on the camera I do not want 100% cooling as QHY says it can damage the camera due to temperature shock. So I start at 15% and gradually increase the power and then set the automated temp control. So my concern is camera damage. Also, for framing and focus, it is important th...

Re: QHY168C Problems-Changing ROI Changes Gain and White Balance

Robin,
I am wondering if a local vendor needs to lend you a camera. We've been at this for months, and there is still a problem. I admit it doesn't happen as frequent now, which I don't know is worse.
Again, the camera is cooling at full power but the settings show power of 40 (15%).

Re: QHY168C Problems-Changing ROI Changes Gain and White Balance

I am not moving the ROI around. I just chance the resolution selection. I do that when focusing with the focus assist and bahtinov mask because the frames are large and it slows the laptop down.

Re: QHY168C Problems-Changing ROI Changes Gain and White Balance

Thanks again Robin. I do not know if these problems are related to the SDK or what. It seems we are nearing finding solutions to the problems. Now, when I change the ROI, the cooler goes to max. Seems loading profiles is OK. I hate to bug you with all these problems, it does make it less stressful w...

Re: QHY168C Problems-Changing ROI Changes Gain and White Balance

Robin,
I downloaded the latest SDK, and it seems that the cooler still changes to max after loading a profile. I hear the fan slowing down and the temp drops fast . If I movethe slider a little it fixes it.

Re: QHY168C Problems-Changing ROI Changes Gain and White Balance

Looks like they pushed out a new SDK and fixed incorrect gain setting. Will have to check to see if this fixes things.

Re: QHY168C Problems-Changing ROI Changes Gain and White Balance

Robin, Yes, that is what it looks like, however, when the gain is set to max, the preview images are grayish and noisy. Strangely the setting on SC shows 150. But when I move the slider just a little back and forth, the proper gain is actually being used. It is also clear from the histogram that the...
