Magnus Larsson replied to the topic 'Do it yourself focuser: which one?' in the forum. 13 hours 30 minutes ago

Hi!

I use the same - the Arduino ASCOM Focuser Pro DIY, version 1 (the one working with INDI). THere has been som issues with the code, and Robert actually adviced me to use an older version of the Arduino software to compile the code. Ask him directly (via the forum or direct email) - he's very keen on assisting, in my experience!
I'm actually building my second of the same model right now, to a second scope.

Hi!

The fits image:

Yes, LX200Gemini driver.

And yes, the "slew complete" settings are at play here. Based on your advice two days ago, I set it to 11, and that worked nicely. Howevr, yesterday, imaging M81, it didn't work. I had to increase it to 20 or even more to be able to complete a slew. I don't have the logfile, though.

(I hope the driver information answers your question about the command set?)

Hi!

Good to hear that it is not just me...:) So how do you cope with it? My main problem with it is that it is that I cannot depend on the scheduler to slew to a specific object and center on it. This situation demands manual intervention...right?

Magnus Larsson created a new topic ' Alignment mystery' in the forum. 4 weeks ago

Hi!

Tonight, I hade a strange problem with the alignment module - first time ever. I was trying to center M81, and repeatedy ordered the mount to slew to it, and the capture, solve and slew to target. However, repeatedy it ended with M81 low in the field. I tried using WCS, clicking on the galaxy core, saying yes to slewing to those coordinates. And still, M81 in the lower part of the image. Finally, I manually, with the handcontrol of the mount, centred M81. And then, doing a capture and sync, and the click on "Show objects in image" I get the green square indicating M81. In the lower part of the image, NOT where it actually is. See attached screendump. Any ideas as to what is going on here? Any settings beeing off, or what might this be?

Magnus Larsson replied to the topic 'Meridian flip still working for people?' in the forum. 4 weeks ago

Hi!

I'm not sure whether I am connecting to the topic or not - I have a Losmandy G-11, so no EQMOD here. But I have problems with meridian flip.

My situation: I've set the safety limit to 5 degrees past the meridian. According to the people who know more about this mount than me, issuing a Goto within 2.5 degrees of the safety limit should cause the mount to flip. According to my manual tests - using the handcontrol, not Ekos - this seems to be correct.

Now I tested this bu trackng a star across the meridian, with 60 sec exposures. I've set the HA to 02, so as to make it happen within the zone of between 2.5 and 5 degrees past the meridian. It tracks, approaches the limits, and then, at 185 degrees, it seems to issue a meridian flip command - according to the capture model. However, I cannot see anything in the Indi panel for the mount. Issuing a manual Goto (with the Handcontrol, not Ekos) to the star it is already pointing to, initiates a Meridian flip.

It seems to me that no Goto command was issued - or what is happening here? Log files attached - Kstars log, mount log, and CCD log.

Hi!

This is something of a return issue - I've had something similar a few months ago. What happens is that I slew to a target, but there seems to be no "slew finshed" signal. THis means I cannot capture, and the align process waits forever. In reality, the slew is completed long ago, but Ekos keeps waiting. It's a Losmandy G-11, Gemini 1. Any idea what is going on here? Mount log attached.

Hi!

Check these threads;

indilib.org/forum/mounts/1979-mount-meridian-flip.html

indilib.org/forum/mounts/1978-no-meridia...-losmandy-mount.html

Does that help? I'm adjusting my safety limits to make the mount flip, still not really satisfied though. What mount are you using?

Magnus Larsson created a new topic ' Guiding wit PHD2 but fits viewer displays guide image?' in the forum. 1 month ago

Hi!

I regularly use PHD2 for guiding, and it works nicely together with Ekos. However, recently the guide image pops up in the Fits viewer, despite using PHD2. This is quite annoying as I cannot close it, because it pops up again on next image download. THis is new behavior the last few weeks. Is there some setting that I might need to change, or what is happening?

Magnus Larsson created a new topic ' Polynomial solution in focus module' in the forum. 1 month ago

Hi!

I just recently noted that I now can choose a polynomical solution, versus an iterative solution in the focus module. I guess this is new, because I haven't seen it before.

So I just wanted to say that this is a great improvement for me!! It works magic. Not only is the focusing more reliable with this (less false solutions, less failures) but it is also far quicker. Now I get focus with 8-9-10 iterations, whereas it sometimes needes 20+ before. This gives a very significant increase in the balance between imaging time - focusing time.

So THANKS!! Wonderful work!!

Hi!
I choose "Losmandy mount" in the setup., That is the LX200gemini-driver, I believe.

Update:

I've learned that the Losmandy G-11 does not flip at the meridian, but at a "GOTO-limit", defaulted at 2.5 degrees earlier than western safety limit. So by setting the hour angle smartly, I can make the scope flip. Or I can adjust the limits and make the scope filp at the meridian.

Magnus Larsson replied to the topic 'Autofocus in Ekos' in the forum. 2 months ago

Hi!

This triggered my curiosity. I'm interested in reducing the unnecessary traffic between the Indi-server (raspberry) and Ekos client (laptop). So what does it mean when you are storing sequence data on the indi server? Do you save the captured subs there, or which data? I'd be interested in not having to download frames to the EKOS client when focusing, but to do the whole processing at the Indi server, so as to reduce download time.

Magnus Larsson replied to the topic 'Mount meridian flip' in the forum. 2 months ago

Hi!

I'm not really sure what you mean. I do a meridian flip with my Losmandy G-11, manually executed with the hand control. Then the RA/DEC coordinates in EKOS changes. RA goes "around the clock" and when flip is finished, it is back to where we started. Same with Dec - it changes somewhat and then lands on the same coordinates.

Magnus Larsson replied to the topic 'No meridian flip with Losmandy mount' in the forum. 2 months ago

Hi!

OK. No, mount does not seemt to flip when I do that - but I do it from Kstars right now. I select a star, allow it to track across the meridian, then tell it to slew to same star again - no meridian flip. I've not tested with handcontrol on the mount, due to all the "Bright stars" being too far away from the meridian right now. I'll test that too, in a while.

Also: when I try to slew to a star that HAS crossed the meridian, the mount does not flip - unles the star is too far west, then it flips. Maybe this has to do with the limits set in the mount?

This is strange, because the mount did flip before - but it is several months since I did that.

Magnus Larsson created a new topic ' No meridian flip with Losmandy mount' in the forum. 2 months ago

Hi!

I just ran into the interesting situation where the mount shoud do a meridian flip, Ekos reports that a flip is initiatied and then completed, but the mount does not move. No flip accomplished, despite Ekos saying so. What's going on here? I don't know if this is a new or an old issue - haven't tried meridian flips for several months.

Kstars log and indi log for the mount is attacked for a sequence when a flip was reported (but not done).

Hrm. Odd. I use default settings, and tje jpg-file I posted here, and it aborts after 180 secs. Du you know which index is used to solve it? (maybe I don't have the correct ones)
