I just bought a new computer and I installed the latest version. In a few days there will be the next LTS and I guess I will update / reinstall. I will try with a virtual machine to see if that is just a matter of libraries in kubuntu 21.10.

Thanks for your reply and best regards!

I am trying to install pyindi-client. Although the installation looks fine (there are several details to improve in the pyindi-client tutorial) when I try to import the library it fails with the following message:

ImportError                               Traceback (most recent call last)
Input In [1], in <cell line: 1>()
----> 1 import PyIndi

     14 else:

     17 try:

Any hint on how to solve it? It is a fresh system in which I have installed kubuntu 21.10 and the latest indi libraries.

Thanks for your attention.


Dear everyone.

I'm having some trouble with and old QHY5 that I would like to use as an all-sky camera. I have been able to connect it through INDI both using Ekos and even with some python scripting. However I have a problem: If I do an exposure of X seconds the download time is X + e, being e a slow delay (which is understandable). For example, if I set an exposure of 10 seconds, the exposure counter takes the 10 seconds of the exposure and then about 11 seconds in which the image is supposedly downloading.

I have seen in other forums that this happened with other QHY cameras:


I have tested it connecting the camera in a raspberry pi (and the client in other computer) and connecting the camera in the same computer (therefore it is not a problem of the network connection). Using different software (for example PHD2 under linux) the camera takes the exposures with almost no delay. From what I have read it may be an error of the camera skipping the first frame when it is connected or something like that (and maybe the INDI driver reconnects to the camera each time that an exposure must be taken?).

Anyone has any similar problem? I know it is an old camera but I really would like it to use it. Any hints?

Thank you for your attention
