Hi!

Yes, it doesni't this far seem to affect the quality of the images. These were as saturated as I could get them - 10 sec exposure in broad daylight, just because I wanted to see the maximum since it seemd strange.

But it is strange isn't it, that it is around 3650 in the fits, but 4092 in the cr2? At least that is the values I get in PixInsight. And it used to be 4096 in fits as well, a few months ago, with this camera (as far as I've seen).

So I'm wondering if something strange is happening in the transformation to fits format.

Hi!

I'm trying to take flats with a Canon EOS 1000D through Ekos/INDI. Image settings is to use fits, not compressed, download to my client. The setup is a R-Pi by the mount and a laptop indoors.

However, when I get the images they have a maximum of 3653 rather than the 4096 that I would expect (given 12-bit capacity). Anyone knows what is happening here?

When downloading as native/CR2, it seems that I get something like 4092.

A fits and a cr2-file is available in a dropbox-folder here: www.dropbox.com/sh/fs744ujp8oed79d/AACfn...E98N8km8Tv2dUBa?dl=0

Hi!

I was referring to "Use pulse guide" in Indi control panel, Mount tab.

Hi!
Nope, I do not have Non-Guide Dither Pulse checked. Should I? What does this do?

Hi!

It looks like this problem has disappeared. It might be something to do with the pulse guide setting in Indi (what does this do?), that I've been toggling on and off and now it is on and it works (although I tried with it on before as well.....hrm). Or it's something with update of the drivers.

Anyway: now it seems to work with pulse guide through PHD2 with my Gemini 2. Maybe I can even take my first image tonight, after 6 weeks of constant trouble :)

Hi!

Interesting. You are using Gemini 2 as well? My setup is a R-Pi with Ubuntu Mate, where the indiserver runs. THen Ekos on a linux laptop indoors.

I have posted at the PHD2 forum, and after having discussed there, they concluded that it probably is not PHD2 related. It works nicely in windows with ASCOM, and OK with Ekos/INdi using ST4 - with the exact same balance and pointing to the exact same spot in the sky. I switch from pulse (wild swings) to On-camera in PHD2, and it calms down. So I figure it must be Indi-related.

So very interesting if you do not experience this. What happens when you switch from pulse guiding to ST4/on-camera? And could you perhaps post your precise Indi settings for the guide cam?

What more could I check and try....?

Hi!

No, I'm talking about swings in RA while guiding - up to 15" in swings,, killing every possibility of imaging, and seemingly triggered by pulses i DEC - when not guiding in DEC, it is smooth. And this is only when using pulse commandes, using ST4-cable works OK. See my previously posted guidelogs for a visual illustration.

Hi!

Any hope of any progress on this? Tried tonight and still same problem: wild swings in RA when mount connected through Indi, much calmer when "on-camera" But guiding quality not as good as it used to be with connection throgu Indi.

Hi!

A slight update: ST4 works, but my experience now, is that it does not work as nicely as I first said. I cannot get guding below 1", even though I previously, with Gemini 1, hade 0,6-0,7" as standard. And the experience among many Losmandy users seems to be that performance is better with pulse. However, I am going to explore this further next week (travelling this week). And if we could get the pulse guiding to work, that would be wonderful!

Hi again!

And now I can confirm that using the ST4-cable instead seems to work nicely. No swings at all, good guiding behavior.

Hi!
So, after a few days of clouds, here is a log with mount driver data as well. Same behavior - wild swings in RA when guiding also in Dec. I have turned Dec on and off a few times - each time I turn it off, RA calms down, each time I turn it on, it goes wild again. Attached is both INDI, Ekos and PHD2 logs.

Hi!

Ah, sorry for not having mount logging. Will supply as soon as I can (next star visible).

I use pulse guiding, no ST4-cable, just the USB cable. I use a Lodestar. Indiserver installed on a R-Pi sitting by the telescope.

I'm not sure which settings I should look at. Camera settings were the same in Win as in Linux. Exposure 1s to 2 secs, Hysterisis and Resist switch algoritms. I have not tried PHD2 in Linux without PHD2, though. But I did try internal guider in Ekos without PHD2, same behavior - and that indicates to me that this is not PHD2 related. Right?

Phomer60: what settings should I check? There are a lot.... Since it works for you (with gemini 2, right, and the Losmandy Gemini driver?), it should be some kind of setting here. Basically, I did not change anything switching from the Gemini 1 to Gemini 2. It worked nicely with Gemini 1. Anything that should be changed doing that switch?

Hi!

I just upgraded my Losmandy G11 to a Gemini 2 (from Gemini 1) and immediatly ran into a weird problem with guiding. Everything else seems fine so far, but guiding is totally off.

What happens is that I get wild swings in RA when guiding. But only when Dec is also guiding. I have attached guidelogs from PHD2 used with Ekos. There is a calibration sequence, then immediately guiding with the wild swings. Then I turn of DEC guiding (set to "off") and RA calms down. Then I turn on DEC and the wild swings starts again.

I log files from Ekos as well.

Then I stopped Indi and switched to Internal Guider. Same behavior, wild swings in RA. Should be in log file as well.

This does NOT happen in windows. I tried using ASCOM and PHD2, and there it seems to work nicely. I can supply log files for this as well from PHD2, but not here now as to avoid confusion.

Any ideas on what goes on here? Any setting in my system, or something with the driver?

Hi!
No idea what changed. Jasem did some magic with the code for the driver... :)

How to do it: the instructions for compiling fron Git is here: indilib.org/forum/general/210-howto-buil...st-libindi-ekos.html

But I guess it will be in the PPA by tomorrow or the day after that. So just upgrade as usual (sudo apt-get update && sudo apt-get dist-upgrade).

Hi!

With Jasem's assistance, I compiled the gphoto-driver from GitHub and ran a long series of focusing, without any of the errors! Hopefully, this issue is solved then.

Hi!

Good to hear that more are experiencing the same issue (well, good in one way, not another....). As I understand it:
1. The RAM vs SD-card issue is unrelated to the focus module problem with the "fast shot" and the error msg "Gphoto is already exposing. Can not abort" and stalling there - nothing more happens. These seems to be two entirely different issues. Right?
2. The "save to client" vs "save to local" is only relevant when you run Indi on one machine and Ekos on another. If you use a laptop running both, then connecting to it via VNC, it should be irrelevant. If you use a R-Pi running Indi-server, but not Ekos, and Ekos on a different computer - then this is relevant. Focus module ALWAYS use "client" because Ekos needs the images to be able to focus. Right?

So, Cakemaker, I can see that you have an exposure AFTER your "Gphoto is already exposing. Can not abort". Does that mean the process was not stalled? Or did you press Autofocus or Capture again? And what kind of camera do you have?

Hi!

I have something that sound precisely the same. Here is a log file where the focuser fails to identify stars, instead focusing on noise. And a fits image here:

Hi!

Here's a screenshot from the focus module, connected to the 1000D and focusing.
