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.

Actually, there's another important advantage: to reduce the read noise. If you look, for example, at the 2600mm graphs, you'll see that at gain 100 the read noise is half that of gain 0.
If you look at the Risingcam's graphs, you'll see that gain 0 is always the best option for both LCG and HCG.

I've made a comparison between the ASI2600MM, QHY268M and RisingCam/Altair IMX571 Mono with the numbers found on their respective official websites and, where values were missing (qhy268m), from the SharpCap sensor analysis found on CN:

To me it's even more clear that the RisingCam camera should always be used at gain 100 (which is gain 0 on other cameras).

Legend:
RC = RisingCam
(number) = Ultra low noise mode, e.g. (2.35)

A couple of other params I don't know how they should be set:

HCG/LCG gain ratio
Offset

Someone has any idea?

For the offset, I guess you can take a look here:
www.qhyccd.com/index.php?m=content&c=ind...show&catid=23&id=226

for the HCG/LCG gain ratio I don't know, maybe this could help

Nice! I must say that their support is really good! Very friendly and fast in answering all questions I asked them! Kudos to them

FYI, I sent the latest firmware to Jasem yesterday, and this morning he pushed it to the repo
If someone has the mono version, now it should work fine.

Hi everyone
Sorry to jump on this thread but I have just bought this camera and it seems to work well.. however on the image settings tab in EKOS it says the image depth is 8 bits per pixel but I am sure that it is a 16 bit chip and I don't see anywhere to change this setting.
I am new to OSC (having only used a Canon DSLR up until now). Am I misunderstanding something here.
Any advice gratefully received.
Thanks
Wayne

For anyone interested I think I have solved it.
The image was set to RGB, when I changed it to RAW it changed to 16 bit

Cheers
Wayne

Hello All fellow RisingCam users.

I am missing a few options for my cam, not sure what is going on but these are the options I have on the controls ? I can't find offset or anything similar to that.

I update Indi on my Raspberry PI. Looks like the driver fail to start.
Does anyone met same issue ?
Hopefully I kept the previous version of Indi.

Up this topic because I still have the problem with the Risingcam IMX571. The cam is not recognized by INDI driver. I use the Touptek driver and the previous version of INDI (before the 2.0.2).
If someone met this problem and found a way to circumvent the problem I would be pleased to know how.
cheers
