Image settings for the RPi HQ camera. #1173
Comments
|
I will try to help as much as I can. Can you post an image from your system so I can see our starting point? |
|
Hi Aaron,
I appreciate your offer to help. Mostly I am using the default image
settings. The only thing I did was to enable stretching and turned on
AWB. For the camera settings, I changed night exposure period to 10.
Everything else is default. I'm not even sure if all the other settings
would matter to the RPi HQ camera.
I switched to your program after using TJs Allsky software for 6 months,
which I mostly liked. I wanted to try yours because I thought you had some
great features like the panorama view. Also I like how you do timelapses
better. However, TJs program did have better explanation for most of the
settings and recommendations for different cameras. I believe that many
users have the RPi HQ, so recommended settings for it and other commonly
used cameras would be helpful.
One other questions while I have you. I want to set up a script to display
the Temperature label. I set the TEMP_JSON env variable but when I run
your sample script, it gives a not defined error. Not sure what I'm doing
wrong.
Anyway, thanks again for the help.
William

I would avoid the AWB setting, especially at night. I does make the colors better, but at the expense of a lot of lost time. The AWB setting causes the camera to take 3-4 exposures in order to find the correct white balance. The colors look better, but if your exposure is 15s, it takes 60-90s to take the 15s exposure. You lose a lot of time on the sky at night. Daytime AWB is not so bad because the exposures are so short. Instead of using AWB, I would enable SCNR Average Neutral to get rid of the green cast. Most of the settings can be applied to the RPi HQ camera. The external temperature script is confusing. The TEMP_JSON file is the output file where the data will be written, so you only define it externally from the script. The following wiki page has an example of how to run the example scripts: https://github.com/aaronwmorris/indi-allsky/wiki/External-Temperature-Sensor It should be noted that the RPi HQ camera has an internal temperature sensor. You may need to upgrade your kernel to be able to read the data. |

Thanks. All good recommendations that I will implement.
As for the TEMP_JSON, I did define the env var with the path to the output
file. I also have a DHT22 in the dome that I read temps from in the
script. When the script tries to write out to the file, I get that error.
I'll keep working at it.

OK. I got the TEMP_JSON figured out and can write out the temp in json
format. Now how do I get indi-allsky to execute the script periodically
and display the temp on the label.

If you define the script in the configuration, it takes over the temperature data from the camera. If you display the temperature in the label, the temperature comes from the script instead of the camera. |

I realize that I must sound completely dense, and I've read through the
wiki many times. But can you explain how you do each of these -
"If you define the script in the configuration" and " If you display the
temperature in the label"
I thought that I was displaying the temp in the label but the label
displays Temp 0.0C and not what is in the TEMP_JSON text file
[image: Capture2.PNG]
If I enter the path to the text file here:
[image: Capture3.PNG]
I get this:
[image: Capture1.PNG]
Sorry for taking your time. If I can understand this, I will stop
bothering you.
Oh, and is there a way to display humidity or dew point. There is no label
variable for that.

No worries. By defining the script in the config, I mean on the Image Tab, in the The temperature field is in the image label by default. It is the line |

I looked multiple times on the Image tab and did not see that field. Then
I searched the code in this file
- /home/uwsd/indi-allsky/indi_allsky/config.py - which appeared to have the
configuration data fields. I finally found that field referenced, which
led me to the Camera tab, and there it was.

[image: Capture5.PNG]
I added the path to the script and now all is good. Now how about humidity
or dewpoint? Is it possible to add those label vars?

By defining the script in the config, I mean on the Image Tab, in the External
Temperature Script setting, putting the path to the external script in
that field. The path needs to be the full path to the script on the
filesystem. The config validation will ensure it can find the script and
execute it properly.
The temperature field is in the image label by default. It is the line Temp
{temp:0.1f}{temp_unit:s} in the image template on the Image Tab. The temp
variable is what will be overridden by the external script.

Sorry, that was my fault, it is the Camera Tab. For some reason, I am not seeing your images, but that is not a big deal. For the Humidity and dewpoint, you should use the The extra text can include all of the formatting, color, and size configuration that you can use the the normal template. |

No worries. It is all good now. Thanks for your help.

For the Humidity and dewpoint, you should use the Extra Image Text File
that is on the Image Tab (I promise) just below the image label template.
This is just extra text included in the image label. You write this text
file using an external program and indi-allsky will read it for every image.
The extra text can include all of the formatting, color, and size
configuration that you can use the the normal template.

It would be nice if someone could post their image settings for the RPi HQ camera. Currently I am using mostly the default settings and it doesn't look too bad, but I think it could look better. I'm overwhelmed by all of the esoteric settings.
