Hi,
I use Canon EOS 6D to take astrophotos. I have always like the Canon's internal temperature sensor at tag E47. Gives the temperature of the camera body in degrees Celsius. With that I can rename my image files and have the temperature as a part of the filename. When calibrating with darks I can get a much better match in temperature.
I do it like this with Irfanview when I rename the filenames:
www.astrofriend.eu/astronomy/tutorials/t...rame-dslr-canon.html
But I have noticed something strange. Earlier I had a Windows astroserver that controlled the camera with APT software. Then I normally got a temperature about 6 degrees higher than the sourounding temperature. Now when I the last 2 year use KStar/Ekos the temperature is about 10 to 16 degrees higher than the sourunding temperature.
Sorry if I ask this question again, but I asked it the Astroberry section and haven't got any answer. I think it's better to asked it here in the Mount section. And I have more information now.
The problem I have is that I'm trying to take photos of the comet C/2022 E3 ZTF and now in January/February it's moving fast. I want to take many longer exposures and need to have the mount track with a Custom Tracking Rate.
First, from the CdC I get the comet's relative speed, but it's in hour and I need arcsec/sec for INDI EQMOD driver.
Tonight I could do some testing of Custom Track rates in Indi EQMOD. Even if I can't get guiding with relative speed when hunting comets it had been good to be able to set Custom Track Rates.
The comet C/2022 E3 ZTF I got (CdC) for the date 2023-01-01 to be =
dRA -0.74arcsec/hour and set Custom RA Track rate to 15.040861444 arcsec/sec
dDEC +2' 10.8"/hour and set Custom DEC Track rate to 0.036333 arcsec/sec
But Indi doesn't accept the DEC Custom Rate and I get these error messages when testing different Custom Rates.
These days I shall take photos of a comet with KSTars/INDI.
Not with relative auto guide, only change the speed of the RA/DEC to matsh the comet.
On this page of EQMOD mount driver there is a button for custom Track.
A couple of days ago I formated my SD card to to do a new instal. I had to start from the beginning agian because I have alltered so much parameters. To my surprize when I did this the labguage of the menus changed back to English, even when I setup the keyboard, time, date to Swedish standard.
Lucky day !

Hi Andrew,
Which Indi driver do mean that I can use and setup for a custom gear ratio ?
I know how to do it in Eqmod but then I must change in the source code and compile, not very practical.

Hi,
A couple of years ago I asked if there was a way to set costom gears ratio in eqmod. It was in this thread:
indilib.org/forum/mounts/5573-eqmod-and-custom-gear-ratio.html
I have not solved that yet. But plan to do it now for my EQ6 mount which operates without the hand terminal.
But before I start this work which I don't fully understand how to do.
Isn't any alternative to eqmod driver I can use instead that can be setup with different gear ratios ?
Or if there is someone that's skill enough to rewrite the eqmod code to have a setup in the menus for costom gears ratio as it is in the Windows version of eqmod ?

Now when I understand a bit better about the problem. It looks that I need to type the command: sudo systemctl restart gpsd often when I start up the Raspberry.
If I want to do it very simple, I want a button on the screen that send this command:
sudo systemctl restart gpsd
To the command window, how I do that ?

I must have done something wrong last time when the date / clock was wrong. Next time I used it and did the recommended restart of GPSD it worked. I hope it will do it all time now.
Thanks for all help !

I have now been out in the dark and use my equipment. It works better now and the GPS coordinates is transfered to EKOS. But still the time isn't corrected.
In the EKOS GPSD it looks like this:
Hi,
Interesting with the script, maybe I don't need it for this particular problem if it not occur more often. But script can solve other things. Are there some examples somewhere to read about what it can be useful for ?
