Hi!
I got an issue tonight with my guiding in Ekos (version Kstars/Ekos 3.5.2 on Stellarmate) via PHD2, after meridien flip.

Just after the (successfull) flip PHD did a (successfull) calibration and started guiding, and Ekos started the next exposure. But after a few seconds, it received a "setlling failed" error from PHD2 and stopped the exposure. I restarted it manually, it worked. The strange thing is that from then PHD2 was still guiding OK, Ekos was still showing the live guiding curves as usual, but it didn't displayed the guiding progress bar anymore in Analyze window, and didn't sent anymore dithering commands after that:

 


(Sorry for my french :-D)

Unfortunatly I didn't have log to file enabled in Ekos at this moment :-/ But I copy pasted the console logs in order to keep tracking of this issue.

These are the lasts lines displayed in Guiding console. After that it didn't display any new line before I stoped the session 30 minutes later (bad weather invasion...).

What could have caused this?

Well, I like to be able to control my picture directly from my living room PC via a TeamViewer connection on my RPI/Stellarmate :-) On my light setup with SA I use the RPI and Ekos/KStar only for that, plus the target pointing using astrometry to manually approach my target and framing. I also tried the polar alignement tool but it didn't goes very well so I prefer to polar align visually.

But when I will use it on travel I will definitivly not use my RPI at all, only an intervallometer or the SNAP port of SA.

Thanks! Okay maybe... However I'm not sure this delay comes from the link between camera and Pi, as if I go on Indi control pannel of DSLR and check "Upload local" instead of "Upload client" it takes much less time (about 5 secondes). But this setting is always overwritten by Ekos for the next picture.

It is indeed not a problem when I shoot on my "big" setup (APO+AZEQ6), on which I autoguide and take long exposures + dithering after each frame. But it becomes a problem with my light/portable setup (lense+SA), on which I dont autoguide, dont dither, and take short exposures (1 minutes / 1 minutes and half max).

> Does it make a different if you uncheck FITS Viewer (Tools --> Configure KStars --> FITS)

Just tried: no, it only makes that FITS viewer doesn't open after Downloading process, but the process still lasts 16/17 sec tonight.

> How large is the sensor?

Its a 650D, I guess same size than 600D. I will try with "Fits viewer" unchecked.

Last night it did it again but with a (little) less time than than the other day: more 16/17 secondes than 20 secondes as the other night. These variation let me think of a network variation... That's why I wonder if in client mode the data transit via network (thus, dependant on network perf) even when all is in local. Is it possible? BTW I checked my setup profile configuration in Ekos: it is indeed in "local" mode.

Hi,

I run Indi+Kstar/Ekos on Stellarmate within a RPI. I run everything locally on the RPI itself, I dont use a remote client. I use a Canon DSLR for shooting.

After each exposure in a sequence, there is a "Download" phasis that takes a while (15 / 20 sec). Such amount of time seems odd: are the data transfered via network altough all is supposed to be local?!?

When I go on Indi control pannel for my DSLR and check "Upload local" instead of "Upload client" in Option tab, the picture is saved directly on the local directory defined in "Upload settings / Dir". It takes much, much less time: only a few seconds (like 5) !! But Ekos doesn't display the picture. However I prefer that because 10 seconds more on each expesure can result in a significative amount of additional intgration time at the end of night..

But there is a problem: when I check this "Upload local" in Indi Control Panl the setting is automatically set back to "Upload client" when the next exposure begins... So I cannot set it permanently.

Is there a stable way to make this "Download" step last only 5 seconds instead of 15/20 ??

Thanks!

My bad I read this too late, I tried several time with a message... Sorry!

You should add a pannel that say this once the message is submitted :-)
