Angelo Franck replied to the topic 'Dithering while guiding?' in the forum. yesterday

Hi guys! I am guiding in Kstars v. 3.5.2, but in the guiding menu I only see the option "Non-guide dither Dither pulse". IHave I to activate this in order to dither while the mount is guiding?
I ask it because I do not notice any message advertising me about the dither in progress between the exposures...

Regards,

Frank

Hi everyone! 
I am working on a project for photometric analysis performed with amateur telescopes and I am developing a python code to do it. 
I proudly use Ekos to perform my observations and for this reason I hope someone of the developers could help me for the issue I am going to introduce you. 
At some step I have to overplot a grid of coordinates to the analysed image I acquired and solved with ekos. 
Could you suggest me some recipe to convert the parameters related to the coordinates stored in the keywords of the fits file of each image in order to reconstruct the coordinate grid for the image? 
Have you some paper to suggest me? 
Thank you in advance.

Hi!
As far as it concerns the initialization of the devices, to be honest I did not try to connect one device at time. I will try asap. Thanks for your suggestion. I surely will update you about.

Hi guys!

I have a question about the session I run in Ekos.
When I start a session for acquiring data I always experience problems in connecting my equipment at the beginning (clicking on the play button in Ekos), especially with the Eqmod of my mount. Everytime, I am forced to restart my Mac and reopen Ekos to successfully load my equipment.

In addition, during the data acquisition, I experience problems in the system that sometimes does not respond to my inputs, as it is busy during this process.
For completeness, I attach the log file I produced during my last run, hoping this is sufficient to understand the origin of these problems.

Have you idea in which way I can solve these problems?

Thank you in advance,

Franck

Ok, great! Thank you for the link.
Accordingly to the local weather I am going to produce one asap to post it here :-)

Thank you again for your support!

Hi Jim, thank you for your reply!

I did not know this method. I have to absolutely try this.
I think this solution could solve some issues I experienced on loading the equipment on Ekos.
Indeed, sometimes I am not able to connect all the devices when I start Ekos. Several times I had to restart my Mac before loading all the devices in a row when I start the Ekos module.
Have you ever experienced this problem?

Thank you again,

F.

Hi wvreeven!
Thank you for your reply.

1. To be honest the reason because I am worried about the switch from 16 to 8 bit is due to the fact that the FOV of the guiding camera suddenly becomes dark with little white stars. In few words I see a considerably contrasted image as a consequence of the change of the read-out dynamics. Is it a way to performa a stretch in the preview enclosed into the guide module?

2. How can I obtain the debug logs? Is there a way to recover the log of the last session I performed?

Thank you again.

Hi guys, I am just wandering if I am missing some steps to configure the guide in Ekos…

My Kstars/Ekos installation is on Mac OS 10.14.6 and I use a ZWO ASI 1600 imaging camera and ASI 120 MC-S as guiding camera. 
The guiding camera is powered via the imaging camera through an USB cable. The mount is directly connected to my Mac via EqMod cable opportunely configured in Ekos. Just to be sure that everything is ok I attach a screenshot showing the configuration of my devices in Ekos with the opportune drivers. 
I had several problems in the guide. The problem I experienced are the following:

1 - During the guiding process, the modality of acquisition of the guide camera automatically switches from 16 bit to 8 bit. I obtain the following message that report this problem:

2020-10-16T20:57:30: [INFO] Switching to 8-bit video.


2 - I am not able to guide precisely. I initially obtain a drift plot that is almost stable (residuals around 1.5 arcsec) for few minutes. After some minutes, however, the plot starts to be highly unstable with drifts of also 10 arcsec. Unfortunately I have not an image to show you for this case…

I checked several times the balance of my equipment, then I would exclude this kind of problems.

Just a little note (I don’t know if this could contribute in part to these problems)…
All my USB outputs cables (that of the imaging camera, Eqmod, focuser.. ) are connected to an USB 3.0 HUB, that is powered directly from my external battery and connected to my Mac with an USB 3.0 cable. 

How can I solve these problems? 
I thank you very much for your suggestion and comments. 
Regards, 

Frank

Thank you for your answer, hades!!
It sounds veery good! :D
In the Kstars manual I also noticed that in the filter icon on the top of the capture module there is also the possibility to check the filters for which I want to refocus every time.
It's great!!
Thank you again!

Hi guys!
Once I've understood the kind of electronic focuser I should mount to my Celestron C8 (I ordered a Pegasus Astro focuser with a stepper motor), I would like to better understand how this device will work with Ekos.

In particular, I would like to understand if there is the possibility to focus during a sequence at certain changes of the external temperature (via the provided external temperature probe), or if the focusing procedure (without probe) is automatically performed during the sequence at each shot.
In addition, is there the possibility to focus at the end of each process performed with a certain filter?

Substantially, I would like to understand how can I set the focusing frequency or conditions in Ekos.

Are there some references online? I tried to look for these info, but without success...
Regards,

Frank

Thank you for your answer. But before buying a device, I was wandering if it is possible with ekos to focus every time I change a filter or in a very limit case before every frame..

I forgot to post the web page with all the listed focusers:
