Re: QHY168C Camera Exposure Time Not Correct

After further testing, I am finding the "last frame" indicates 0.4 seconds shorter than what the exposure time is set to. For example, if it is set to 10 seconds, the last frame is 9.6 seconds. 20 second exposure will shot the last frame 19.6s etc. at USB traffic 10. When I set usb traffic to 0, tha...

QHY168C Camera Exposure Time Not Correct

I installed the January 2019 update again, and am running my camera with the new drivers I installed. At 1000ms exposures and USB set to 10. I am noticing that the fps is about 1.1 to 1.3 in the bottom left corner. To check if the exposures are not correct, I decided to watched it for 60 seconds and...

QHY168C Doesn't Work, Give Error calling for Wrong Image Resolution

I updated sharpcap to the latest version from my previous January update. Now, my QHY168C camera will not start up after I select it in the pulldown menu. It gives an error, telling me to unplug the camera or try restarting sharpcap. Below the message it read some error and lists a resolution that t...

Sensor Analysis Gain Range and Steps

I recently bought a new camera for astrophotography, and immediately did my sensor analysis. I have noticed that Sharpcap devides the gain range into 6 steps. Yet, someone posted their sensor analysis on cloudynights, and I saw his gain range was divided into 14 steps. Is there a setting where I can...

Sharpcap 3.2 Question

I am curious about the reasoning to keep the live stacking feature as part of the same program, rather then separate it out as a separate program, like DSS live. This would make programming easier I would think, especially the programming for two-monitor viewing could be eliminated. With two program...

Re: What do the red, blue and green sliders technically do?

Thanks Robin, I guess the answer doesn't really matter too much perhaps. When I use the smart brain to determine optimal exposure, I assume it bases it on the color slider settings right? I have mine set to R/G/B = 80/70/130 where I get a good color balance with my QHY224C. When doing the sensor ana...

Re: What do the red, blue and green sliders technically do?

Robin,
I am still a little confused, since the sliders go from 1 to 255, with 128 being center. How does this translate to the 20dB scale?

Re: QHY224C Working Well Now (Phantom Galaxy - M74)

I forgot to mention, I also used a Bahtinov mask, and the focus aid in Sharpcap to get optimal focus.

QHY224C Working Well Now (Phantom Galaxy - M74)

I posted this shot also on another forum, but here I want to emphasize that thanks to the smart brain using the recommended settings, I got my best shot of this faint target to date. Also, I now take darks right after an imaging session and apply a offset of 40, even though it should not make a diff...

Re: Smart Histogram "Read Noise Limit" Setting

Thank you! That was a long read, but it gives me a good feel of how that setting fits into everything. Probably somewhere between 5 and 10% is fine in most cases.
