I built all from latest git sources today. The modified handling of m_DownloadEstimation works for me (as did Max' workaround before). No timeouts after setting small ROIs and resetting to fullframe. :cheer:

Hi,

same happens here. Disconnecting my DSP 2600c in Indi control panel (KSTars and Ekos still running), disconnecting cam from USB, re-connecting USB and connect again in Indi control panel. Driver crashes immediately (KStars/Ekos as well).

I built everything from the latest git sources.

Hi,

I had similar problems with my DSP 2600c Pro (IMX571 sensor) using the ToupTec driver. Timeout failures after setting a subframe (during AF) and switching back to full frame again. For me, AstroMax' solution solved the problem. But at the moment you have to build the driver from Max' GitHub fork by yourself until it will be deployed.

Good point. So the focus routine can collect the needed data from the mount (f#) and camera (px size) sections.

Concerning the CFZ discussion, to determine the microns per motor step one could simply measure the max. drawtube travel and the corresponding step delta and divide those figures. So no need to know the drawtube screw pitch and motor scale.

The linear 1-pass algo (in principle any focus algo) then could have 3 additional (optional) input fields: "Microns per motor step", "Critical focus zone in micron" and "Desired step size in CFZ units". The latter can default to 0.5, but the user can overwrite it (using 1, for instance, or whatever).

The calculated step size would then be "Desired step size in CFZ units" x "CFZ in micron" / "Microns per motor step". Alternatively, the user can ignore those additional input fields and enter the step size manually as it is today.

Thanks for the explanations, and your project sounds really promising, I'm very curious!

Hi John,

I greatly appreciate your approach since I face the same issues with my EAFs. Only "linear" works, but not very reliable in the 2nd pass.

Question about the standard deviation weighting of the fit: The standard deviation will be calculated from all HFR values obtained from the field, correct? The HFR distribution depends (1) on the distribution of the star brightnesses in the field and (2) on local effects (seeing) on individual HFR values. So (1) will be nearly constant for a given focus field, but (2) varies and is a measure for the "quality" of that particular focus frame. Or am I making a mistake here?

Nevertheless, I would be very happy to test your routine!

When I remove the "Desktop Pager" from the taskbar panel it expands over the full screen width as it should. For my multiple desktops I use the desktop switching hot keys (shift-alt-left and -right) instead...

I compiled indi-toupbase witz this additional line of code and it seems to work for my cam as well.

I can now

  1. take a full frame picture
  2. set the ROI to 50x50 and take another pic
  3. reset to full frame again and take a 3rd pic without getting a timeout error

Hi,can you please tell me where you did this change exactly? Was it in indi_toupbase.h

INDI::Timer m_CaptureTimeout;
uint32_t m_CaptureTimeoutCounter {0};
// Download estimation in ms after exposure duration finished.
double m_DownloadEstimation {5000};
where you changed the 5000 ms to 10000 ms?

It makes no difference setting it to 100 % or 1920 pixels. The taskbar is clipped at a bit less than half the screen width .

Hi,

might not be a problem of KStars, but under Raspbian Bullseye 64bit my taskbar is about only half of the screen in width. When I limit the taskbar width to 720 px, it is complete:



When increasing width, it is cut off:


I'm running a screen resolution of 1920x1280 in VNC (with HDMI dummy, but without dummy and 1920x1080 it is the same). Maybe someone came across this problem and found a way to solve it? Didn't find anything on Google, not even a hint...
