For the offset, I guess you can take a look here:
for the HCG/LCG gain ratio I don't know, maybe this could help
What I have understood is that the threshold of 900 is the limit where you switch from LCG to HCG. The only advantage is to get back to a full dynamic when switching from first mode to second one. It seems that for cameras like Zwo or QHY this is transparent for user because they switch automatically between the two modes.
After the choice of LCG or HCG is up to the user. Maybe for lucky imaging or use of filters like L-Extreme from Optolong HCG might be better than LCG.
Do you know what is the wrong info that have been given by Risingcam engineers ?
Do you mind if it could be a good idea to have a button "search object" in the astrometry tab that open a search panel with a goto button ?
I don't understand all in this paper, but it seems that there is all explanations for all parameters that are in the control tabs.
I will try to read, re-read it as long as I can't understand all (if I succeed to).
Maybe HDR combine low and high gain to give a better result. Who knows ?
Yes that is what I understand. Those 18db are coherent with a 900 gain.
I don't know about HDR. Maybe it can takes 2 captures one LCG, other in HCG. But this is only a supposition.
Last info from Risingcam
Last news from Risingcam.
Eddie from Risingcam send to me some information on the ATR3CMOS2600KPA camera.
I share it here
There is in controls tab of the Touptek driver panel a button heat that propose 2 options connected or disconnected. Maybe this is the dew heater. But I am not sure.
So the error message about failure getting sensor temperature is still here.
Might be on a timeout while trying to get info from sensor without answer of it. Seems to disappears when doing off/on on cooler button. As if the sensor is not online since we do it.
There is an ongoing discussion on this camera.
I am an owner of this cam. Works fine with INDI apart the issues I mention on the other discussion.
The driver toupdate covers the toupcam and this cam too.
This is the same I sent to Jasem.
You get in touch with Eddie too. A sympathetic contact very listening at Risingcam.
I am in touch with someone from Risingcam.
They gave me some curves to try to fix my hesitations about the gain value. But the choice of the right value is still not really clear to me.
And I don't have many clear nights to check it.
For the error concerning the temperature sensor information. I sent the sdk I received with the camera to Jasem. As it seems more recent than the one used for the INDI current version, I hope it will fix the problem.
The underlying problem is that I am not very confident to the value returned in Ekos. But I might be too careful.
