Hi,

Update the recommendation for the best settings by the current version SDK.

Karas said he will later make a Python script that can run sensor analysis under LINUX. It can be used to validate this data set. And get finer discrete values. This data set can now be verified under linux using Pixinsight, and since I'm not a PI expert, if anyone is interested they can follow this tutorial: www.lightvortexastronomy.com/measuring-your-camera-sensor- parameters-automatically-with-pixinsight.html

The current Mode0 recommended settings are as follows.

HFW = On
LCG = On (By threshold AUTO)
LN = On
Gain 177
OFFSET = 700

Reasons Why and How to select：

Slightly less than 1e/ADU to obtain the best sampling, one electron converts one ADU.

Consider a limit capacity of 60ke for 16bit, and a full well of no more than that amount of RMS after deducting the noise component is available.

Consider the loss of dynamic range and keep it above 14.

Consider the noise distribution characteristics, the histogram should be closer to the Gaussian distribution.

Consider pre-addition of voltage to make all histogram values greater than 0.



2023 Jan Toup Ascom Driver （Same file with INDI 3rd）


QHY268M

I recently updated my system and Touptek INDI driver seems to be changed dramatically:
- Now it takes offset between 1 and 31 only
- If does not show parameter for switching between high and low gains
- gain parameter does not switch between low and high gain as it used to be
Looks like now I am supposed to switch between low and high gain using INDI control panel.
Is this expected?
I much prefer the old way of doing things because i was able to switch between low and high gain just by using the gain value.

I've also got the problem with offset being 31 max but I haven't tried gain adjustment yet

Hi everyone
I have the Omegon veTEC571. Connecting using the omegonpro driver, I don't see the offset issue and all the other stuff works too. I wonder if the Omegon and other Touptek re-badged models really do use the same code?
The libraries seem different. Here are the listings built from NOU's scripts for the current stable:

Can anyone confirm?
Cheers and clear skies,

For OpenSUSE tumbleweed using the later release of the RisingCam IMX571 (colour)

ls -l libtoup*
lrwxrwxrwx 1 root root 16 May 23 13:30 libtoupcam.so -> libtoupcam.so.53
lrwxrwxrwx 1 root root 22 May 11 16:20 libtoupcam.so.53 -> libtoupcam.so.53.22376
-rw-r--r-- 1 root root 44642257 May 11 16:18 libtoupcam.so.53.22376

ignore the dates as I was playing around with the RisingCam libs

My offset settings are greyed out completely

with my vetec571M the maximum blacklevel is 31, with my vetec571C 256 is possible (my standard) in the INDI Control panel using the Toupcam driver. With the Omegonpro driver both cameras work with 256. It is still not possible to use the offset setting in the EKOS panel.

CS, Markus

Thanks to the authors for their work! Now it is possible to use all camera functions

I measured the parameters for my ATR3CMOS09000KPA camera, with an imx533 sensor.
It may be useful to others, although it needs to be done for each camera.
1. lownoiceHCG
2. lownoiseLCG
3. normalHCG
4. normalLCG

more than half a year later, the offset bug in EKOS is still not fixed. I can set the offset using the INDI panel (disconnect, reconnect, set offset) but it is an annoyance and the value does not get written into the fits header.

CS, Markus

I have absolutely no issues setting offset from Ekos. It's set correctly in the driver like other cameras. This is Astroshop Omegon but it's using the base Touptek driver.

SORRY Jasem, my fault! just found the error, I had an old version of the toupbase driver in /usr/local/bin and this one got executed. I believe I did this at some point to avoid another error in the official release. Now I make use of the latest driver in /usr/bin and everything is fine.
Again, sorry for the inconvenience.

Hi
Has anyone had chance to test the latest SDK with 3.6.9? Is all well?

lrwxrwxrwx 1 root root 27 feb 1 06:11 libomegonprocam.so.55 -> libomegonprocam.so.55.24239
-rw-r--r-- 1 root root 22161304 feb 1 06:11 libomegonprocam.so.55.24239

TIA,
