Are you sure this isn't just a stretched image compared with a non stretched image?

Paul replied to the topic 'Slow RPI3 Offline Platesolving' in the forum. 2 weeks ago

Anon,
I am going to suggest a few things to assist but I am also wondering which Raspberry Pi you have. I suggest 2 or 3 are the only practiacl options, with a fast SD card.
First of all I would bin 2x2 or more and reduce the exposure time ( I use 1 second). The binning produces a significantly smaller file to work on.
Secondly, I would use the Luminance rather than Red filter as this will be much brighter.
Thirdly, have you tried selecting the dark option as this should remove any hot pixels that could be slowing things down.
and finally, tand he most important for me is that you need to have the telescope pointing close to where INDI thinks it is so the search is starting in the right region, otherwise it takes an excessive time and times out.

Thanks for the tip, VNC performance has never been an issue for me but I am always looking at ways to improve things so I will investigate x2go.

Paul replied to the topic 'Bandwidth utilization: indi protocol vs vnc' in the forum. 2 weeks ago

I haven't done a comparison but there is no doubt the bandwith required for VNC is far greater while actually being used.

The problem is that you need to keep your main computer runnning using the INDI protocol whereas I can VNC into my Raspberry Pi and because it is running independently I can close the VNC connection and everything keeps running.

Eric,

The counter reset issue is fixed, however the type still changes back to "light".

Eric,

Thanks for your response, the mount supports it but at least I know it is not a programming problem.

Paul created a new topic ' Tracking rate not changing after slewing to the Moon' in the forum. 1 month ago

I am a couple of weeks behind the bleeding edge because of make issues and running on a Raspberry Pi 3 with a Losmandy Gemini 2 G11.

After slewing to the Moon I was expecting it to change the tracking to Lunar rate but this did not occur.

Is this the expected behaviour?

Version about 2 weeks old.

1. This is because you use the spin arrows and not a digit entry, correct? So you require additional intermediate values? Yes or the ability to configure it for my own use.

2. Isn't this because you are not actually editing the job you want to modify? When you are in edit mode, the "+" button changes to a check, to validate your changes. Please confirm. No, this happens whether I use use the up/down buttons or edit it directly - any value over 900 gets set back to 900. It can be seen in simulated camera as well.

3. I have a differential pushed in review to fix that sort of thing and properly support locale characteristics. But the dust needs to settle first on kstars-bleeding. I am build locally on Raspbian but the latest kstars build is failing.

4. The count reset issue is fixed and tested OK on my side, but the differential might not be merged yet. Stay tuned for this. Will do.

Paul created a new topic ' Capture settings > 900 seconds are not maintained' in the forum. 2 months ago

I have recently started using 1200 second exposures for narrowband.
There are three issues with this...
1) When incrementing the exposure times it jumps from 900 to 3600 seconds - intermediate steps of 1200 and 1800 would be nice and even better if this was configurable.
2) When any value over 900 seconds is set and you go to any other tab and then back to the camera tab it always sets the exposure time back to 900.
3) When logging the exposures at the bottom of the widown it has started displaying the times in an exponential format.

Further, and I am not sure if this is related, when taking exposures which restart when the guiding exceeds a limit, the exposure counter if being randomly reset back to zero. I have only started seeing this happen when using 1200 second exposures.

Why not frame it as you want, run an alignment with "do nothing" to load the co-ordinates and copy the result into a scheduler job.

Paul replied to the topic 'Failure to connect to QSI camera after build' in the forum. 3 months ago

I did that by running rm -rf * in the libindi directory and running cmake, make and make install and the same thing in 3rdparty, twice.
It did not work as the 3rdparty build keeps failing.

Jasem,
I have been build from source for a couple of years with the occasional issue.
I build all 3rdparty.
The problem it now keeps trying to connect to the camera and failing.
I have added another log file.
