Stephen Wong replied to the topic 'Slow RPI3 Offline Platesolving' in the forum. 3 months ago

OK. I've located the problem:

1. I did messed up the FOV - Thanks wvreeven
2. EKOS is not passing parameters to solve-field (well at least at "Load & Slew"). I did point the telescope simulator close to the targets, specifies the FOV. And then I've found from the log that the -3, -4, -5 params are not passed - this caused the solver to do a blind solve. In the options I did find the params are correct. Just somehow it's not being sent to the solve-field command. See screen cap. If I run the same command myself at the shell, by adding the -3, -4, -5, the solver is able to get the result in 90 seconds.

Stephen Wong created a new topic ' Slow RPI3 Offline Platesolving' in the forum. 3 months ago

Hi
I was trying to use the offline platesolving (astrometry 0.67) with my Raspberry Pi 3 on ubuntu 16.04. I've found the offline platesolver is very very slow and run into timeout. I used a FITS file captured with my Atik 490EX (with Tak 85ED with 0.67 reducer) and load it with "Load & Slew" to test. See below logs.

If I use the online platesolver that's no problem. I saw from other posts saying a RPI3 usually takes 30-60 secs to solve, if it's offline. But you can see from the log it takes a lot of time on certain steps. Is it normal?

Stephen Wong created a new topic ' Can I specified to the CCD simulator to load my own FITS file?' in the forum. 3 months ago

Assuming I have captured a FITS file on disk. Can I specify the CCD simulator to load the FITS as simulate the image capturing?
What I'm trying to do is to test the offline platesolving in EKOS.
I have very limited time in image capturing session on the field, so I just want to test the offline platesolving, making sure it would work when I'm on the field.

Thanks!

Stephen Wong replied to the topic 'KStars icon missing in my LXDE environment.' in the forum. 10 months ago

I have the same issue
I am using Raspbian and I build the Kstars myself from the pi3.

The icons are critical to me. When I focus using the focus frame, I need to zoom in/out, and enable/disable the star circles. Now the screen shows the "text" on the buttons, but the window is not large enough to display all the text. Meanwhile if it's the icon, it's a small square box which I can see the icons without problems.

yes I saw that button, and able to switch it off. Yet I do this in a separate ubuntu, not raspbian. Anyway issue is resolved. Thank you!

No.
But it turns out I'm suffering from some other problems in the raspbian. I switched to ubuntu and update to the latest version and able to get the zoom working.

Stephen Wong created a new topic ' Unable to zoom-in (further) in the focusing module?' in the forum. 11 months ago

Hi,

I'm using Kstars 2.9.1 in Raspbian. I've found that in the focusing module, I cannot zoom in beyond 100%. e.g. I can't do 120% or 150% in the framing setup.
Is this normal?

Plus I use a Bahtinov mask to focus, which I only need the framing and zoom to work. I do not need the star detection and FWHM. I can see the EKOS always try to detect the stars, and draw circles around them. Can I disable the drawing of such circles?

Stephen Wong replied to the topic 'My Raspberry Pi 3 Setup' in the forum. 12 months ago

Well I'm living in Hong Kong. Me and my friends mostly heads to the dam at the east side which is a protected area that only allows public transport (e.g. taxi) to get in. Private cars are not allowed unless there's a permit. So every time we have to carry like 10-20kg of equipment and get on a taxi and then walk for 800m slope to get to the area. So we have to think of different ways to lower the weight of the equipment. We also have to think of how to set up as quick as possible as we do not have much clear time during the night.

Hi Wim,
May I ask the fastest FPS (say certain resolution like 640x480) you can achieve on the rock64 usb3?
Thanks
