Unfortunately I can confirm that the Raspberry Pi version crashes as well since a couple of days.

Guido Muesch replied to the topic 'Kstars + additional CCD viewer' in the forum. 9 months ago

Thanks. Also interesting, but I would like to stick to my pure Python client.
Currently experimenting with Kivy it could potentially run under Windows and Android as well.

Guido Muesch replied to the topic 'Video Astronomy like viewer (Live Stacking)' in the forum. 9 months ago

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.

Guido Muesch created a new topic ' Video Astronomy like viewer (Live Stacking)' in the forum. 9 months ago

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.

Guido Muesch created a new topic ' Kstars + additional CCD viewer' in the forum. 9 months ago

Hi All,

I am experiementing with implementing a standalone viewer for INDI cameras outside of Kstars. As Python is my preferred language I based my work on DCD , because I prefer not to use a C binding.

I still run Kstars to control the CCD settings. So, whenever my viewer requests an image it will also be displayed in Kstars FITS viewer. Am I doing it wrong? Could that be prevented?
BTW, I get a similar issue when switching to the Guide tab in Kstars/Ekos, where I often use the "loop" feature to focus my cameras (when streaming is unavailable or prone to crashes). When switching to the "INDI control panel" and taking an image it will still end up in the Guide tab and not in a seperate FITS viewer.

I assume it is a design flaw of INDI that a client cannot register and deregister for a specific BLOB source. If I am not mistaken, a client receives all BLOBs when it does an "enableBlob". Well, ok, the client could filter and decide if it is currently expecting an image from that source or not.

Guido Muesch replied to the topic 'libindi_3rdparty package for Arch Linux?' in the forum. 9 months ago

Hi avilqu,

I am experiencing the same issue and unfortunately cannot offer a solution, sorry. I also installed the few additionally needed 3rd party drivers manually.

I see the main issue with the INDI 3rdparty drivers that they, as a whole, have a lot of dependencies to other packages, 3rd party libraries, etc. So as a big monolithic package it is easy to fail if a single of those dependency cannot be resolved.

Wouldn't it be better to split the 3rdparty drivers into seperate subpackages? E.g. by vendor? Nobody would need them all at the same time.

I am currently experimenting with a CCD driver (old QHY5 and SSAG), which can be build outside the INDI and 3rdparty source tree with only minmal changes (actually only having its own copy of a few scripts from cmake_modules). So it should be possible.

Cheers
Guido

Thanks Jasem,

I was looking for a way outside the INDI library, e.g. using indi_getprop or pygtkindiclient. But with your hint I learned to look at the bitmask of *.DRIVER_INFO.DRIVER_INTERFACE. Great!

Guido Muesch created a new topic ' List of CCD devices from indiserver?' in the forum. 9 months ago

Hi All,

I am experimenting with an INDI client accessing CCD devices.
How would I get a list of CCD devices? Is there a naming convention (device name ending in "CCD") that I could search for?
OK, once connected, I could search for certain properties.

Guido Muesch replied to the topic 'V4L2 CCD and stacking?' in the forum. 2 years ago

OK, found it myself.

The stacking code is protected by "#ifdef WITH_V4L2_EXPERIMENTS", which is nowhere defined. It was introduced Mar 7, 2015 by geehalel. Any reason why? Stability issues?

This would have been interesting for Webcams that do not support longer exposure times.

Guido Muesch created a new topic ' V4L2 CCD and stacking?' in the forum. 2 years ago

Hi All,

I do not find the stacking option for V4L2 CCD as described in http://indilib.org/devices/ccds/web-cameras.html .
I am using a Philips ToUCam (without long exposure mod).
I am missing this "linearization" or anything related to stacking in the "Capture Options" tab of the INDI Control Panel nor on the "CCD & Filter Wheel" tab of Ekos.

This is my first post here, so something about me: I started with astronomy roughly two years ago and also did some astrophotography with an Olympus E-PL 6 attached to a Skywatcher Heritage 130/650 and a Bresser Mak 127/1900. Using an NEQ3 Mount, exposure is roughly limited to 30s, due to wormgear errors. Therefore I upgraded to Synscan and try to get INDI running on a RasPi 3 because I hope guiding would solve some of my issues.

Cheers
Guido
