I am still in a playing phase with INDI (but aren't we all?). So I just use INDI to point to an object and have a look. Either visually or if I am lazy by taking an image sitting inside behind my desk. Well, a single image leaves much to be deserved, especially long exposures due to noise.
Wouldn't it be nice to have a live viewer that acts like the cameras used in video astronomy? Taking multiple exposures and stacking them thereby eliminating a lot of the noise. A lot of configurable post processing could be foreseen: Exposure time and amount of frames to be stacked, stretching the dynamic range of the resulting picture by selecting min and max, using different mappings (log, sqrt, ...).

Are there any plans in this direction?

I am currently experimenting with implementing a pure Python INDI camera client. Maybe it can act as a demonstrator for a live viewer.

Well, INDI is just drivers. So here you're talking about Ekos? There is "Live Video" button in Ekos, but it just displays frames as-is. If you'd like to contribute to Ekos to enable such functionality (Live Stacking..etc) that would be a very welcome addition. Ekos is written in Qt & C++.

You are right. I wrongly used the term INDI describing everything from drivers to clients. I also find it confusing that Ekos is described like a seperate program, but is actually a part of Kstars. There is no standalone Ekos as far as I know, isn't there?

I am not much into C++ and Qt, so I will continue experimenting with a Python viewer, but once I get some interesting result, I can still consider porting it to Ekos.

Correct no standalone Ekos, but it is often used to talk about that tools which is _within_ KStars. Good luck with the live viewer!
