Magnus Larsson created a new topic ' Slew not finishin' in the forum. 2 hours 34 minutes ago

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. 5 days 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. 6 days 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. 3 weeks 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. 3 weeks 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. 3 weeks 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. 3 weeks 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)

Hi!

OK, so binning might be playing with me here. I normally have binning 1 x 1, have no idea where and why it suddenly should be something else, but I'll check next time it's connected (then the clouds part and I set it all up).
If FOV is something around 43 x 33 with binning 1 x 1, should it not be a clear fraction of this with binning 2 x 2, that is, 21,5 x 16,5? The 17,2 x 12,8 sounds odd, doesn't it? Or there are other things in play here, producing those numbers?

And: when you solve the image, what are your parameters? I just can't make it solve.

Magnus Larsson replied to the topic 'Alignment and plate solving w guide scope problem' in the forum. 4 weeks ago

Hi!
Yes, I seem to have the correct pixel size and resolution in the Indi panel: sensor is 752 x 580, pixel size 8,2 x 8,4 microns.

The aligment tab shows a FOV of 17 x 12 arc minutes, see the attached screenshot. But: I can solve an image on nova.astrometry.net, and that gives me a FOV of 43.3 x 33.4 arcmin. The image I solved there is attached too.
And: I cannot solve this imate with the offline solver in Ekos. I do Load & slew, and a blind solving, but it aborts after 180 seconds. Can you solve it?

Yeah, well, it is set: 500 mm focal length and 70 mm aperture. But how does INDI make that into some 17' FOV? No other settings I should check?

Magnus Larsson created a new topic ' Alignment and plate solving w guide scope problem' in the forum. 1 month ago

Hi!

This is of course a problem on my way to try and use the new PAA, but it's not directly related to that so I post as separate topic.

When trying to use my guide scope in the aligment module, two things happen. When I switch to it, the FOV gets filled in with a quite small number (like 17 x 14', or similar - don't have it connected right now). But the FOV of the guidescope should be more like 45 x 35'. So where does these fgures filled in the FOV come from? And I cannot change them. And I cannot see where in the Indi control panel they would come from.....?

Secondly, and possibly related to this: the solving consistently fails. I use exposure times of 0.5 secs or 1 sec, there seens to be no gain control on it (a Lodestar). Is there anything I can tweak to be able to solve it? When saving an image and uploading to nova.astrometry.net, it solves (after a while).

Magnus Larsson replied to the topic 'Canon 350D suddenly not working?' in the forum. 1 month ago

Yeah I know about the skies....;) Sweden here.

I get the strange errors at times when starting, or if I've had to reboot my Raspberry. If I get errors with the 350D, I normally nowadays turn camera off, reboot the Raspberry, and turn camera back on.

Mine works nicely (for being a 350D) now, so your should work too...strange.

Magnus Larsson replied to the topic 'Canon 350D suddenly not working?' in the forum. 1 month ago

OK, so next idea that I just remembered: I had some problems with power. I run my 360D with an AC-converter. Some failures in this, probably when the shutter opened and the current increases, caused very weird problems for a while. I exchanged all contacts to Andersom Powerpoles, and after that problem disappeared.
