Binning, read noise, and full well capacity

I'm trying to calculate the dynamic range/number of stops for my ASI183MM after a 2x2 binning. My questions are: 1. How do you calculate read noise after binning? 2. Do you simply multiple the full well capacity of a single pixel by the number of pixels being binned. Example: would the full well cap...

EAF and Auto Run

How do you set your EAF to change focus each Auto Run session? I have a refractor and I need to be able to change the focus with each change in the EFW to correct for chromatic aberration.

Clarification on 12-bit to 16-bit conversion and binning

When the software converts the analog signal from a pixel from one of your 12-bit camera and converts into a 12 bit binary number. Let's say the Gain is set at unity and it reads 2000 electrons as a ADU value of 2000 or 0111 1101 0000. Now the ASICAP software converts that into a 16-bit image (.FIT ...

Re: FIT header

Between the time I made this thread and now, I did find a batch FIT editor program. I can give you the link if you like.

FIT header

Is there any way to change the key words or nomenclature in the FIT header or how ASICAP enters information into the FIT header. Like listing the time the observation was made as TIME-OBS or saving the exposure time in seconds rather than microseconds.

ASI183MM-Pro and linearity

According to your site, the full well capacity of the ASI183MM is 15,000 -e per pixel. From what I understand, some manufacturers will list how many electrons can fit in the well before it becomes non-linear as its full-well capacity. From what I read, that's what SBIG does - that their cameras can ...

It did work before and my phone does support 5G.
Hello, let's do more checks:
- can you see the ASIAIR_xxxx WiFi signal in the WLAN list?
- how about the power supply, did you use the original converter and black cable came from ASIAIR?
I am getting power but no WiFi signal light.

ASIAir wifi won't work at all

The wifi on both of my ASIAir don't work. Do you do repairs on them?
