I update my desktop MINT 21.1, with Kstars V3.6.7. First, why on the Jasem's Ekosphere site, are there no more announcements of new versions, with added or modified functions?
I launch Kstars to try it in simulation mode. I can't even take a picture in simulation mode! When I connect a webcam same punishment.
I add, I have big problems with autofocus. No way to use it. Some times the focus is good, in agreement with a Bahtinov. The next time it is nonsense, the focus is successfull, according to Ekos, but the stars are football ballons ! I do tries and tries, with Kstars V3.6.6, on the sky during two weeks in vain. I am going to try focus with another software in order to see if the issue comes from Kstars ou my device, a DIY focuseur with MyfocuserPro2 driver.
OK. And now it is difficult to back previous version.
Except the last release, I cannot compile other version. And it is very long.
Why indi and kstars deb of a one or two previous version are not kept on the server? It would be eayer to install.
I am trying to use the scheduler in simulation mode from yesterday. It is catastrophic !!!
I set up M31 at 22h, it is on the est side.
I set up a sequence with 2 minutes exposition and 3 captures in SHO and repeat twice.
I set up slewing, focus, alignment and guiding.
Once the pla launched:
OK for rotation to the objet.
If I delete the focus option.
I I delete the alignment option.
The guiding goes in preview mode round and round.
So I click on Guide. Calibration and guiding OK
No capture because the mount wants to flip the meridian !!!!!!! M31 at this time is on the Est !
I am afraid because I am going to go in south of France for 2 astronomy weeks with huge use of scheduler.
I am OK with the calculation difficulties but the size of the frame, even designed by me. It is little less than 100x100.
Thanks for your answer.I am not a programmer so the link you gave was not very accurate for me. I understand it may be some problems with the calculation. But your result is very very different from Iris, Siril and Pix. Are we standing an answer from Jasem ?
I try to draw a frame on a preview by shift clic but no result ???
after using this new feature, some remarks:
- the way the square must be set on the image is not very convenient. It's best to draw the frame on the image at the desired location and size. As all the other software do: Pix, Siril, Iris
- the results of statistic, particulary sigma, of the draw is very different from the three others software: Iris, Pix, Siril as you can see on the joined images. Why ?
Thank for your answer.
an another issue with the Build filter offset. It don't keep the parameters #run and the filter reference if modified. Each time you launch this process, the #run value is 5 and the one initially marked with a star is always selected.
I am going on testing the Focus module, the Build Filter Offsets. I start at position 5000.
For the Red filter, the results are curious, from 5400 to 8005 !
For the green, as usual, the focus is around the initial pos, 8005 and also curious. On the run 4, the process fail. The Stop button is no longer active. So I can close the Build Filter windows or the Filter setting windows.
MAP is the right focus in french (Mise Au Point).
The initial step size I use the one calculated by the Focus Advisor.
The third issue is that the focus is always close to the initial position choosed:
Initial Pos Focus Iteration
5000 4994 13
9000 8995 14
Except the first focus process, all the others need 3 iteration before reaching the focus. All the tries are made with same parameters (step size=5, hyperbola). Just the initial position changes.
Initial step size=5
Try with initial step size= 20 => fail
Try with initial step size=25, hyperbola:
4000 4119 10
8000 8050 11
2000 fail regression curve R2=0.631256 limit R2=0.8
5000 5090 29
9000 fail regression .....
Try with step size=25, parabola.
Initial Pos Focus Iteration
9000 9008 10
2000 1984 10
8000 8038 10
4000 4014 10
5000 5053 10
The curve is still very flat. And the initial HFR is very low, less than 1.
I am exploring the new Focus tab parameters. I use it, in simulation mode, because the weather is very bad at this time. The form of the V curve seems curious: a straight line or quasi.
The setup is F/D=6.5, aperture=80, 1 step=7.9 microns. The focuser needs 10000 tick in order to travel the 79mm of the focuser.
Into the Settings tab, if you check sub-frame, this setup is not memorized. The next focus will start with the full field option.
I can do tries from 12 to 19 of august with , I hope, a better weather.
No. I read it. Intesting but it doesn't answer right well, it is not the same device.
And more, we have to manage 3 cameras:
- astrometry on a finder.
As you know Lhires III is a spectroscope. The question is : can we manage this device with Kstars ?
- guiding on a slot (or a split I don't know the right word)
- focus on a ray positive or negative (clear with dark background or vice versa)
Thank you for your answer. I understand your reasonning.
When the conditions are better, I don't change the exposure time, but the total exposure, meaning more captures. And primaly, I check the 3 sigma rules in order to determine the minimum time exposure.
If I setup filter bandwidth=8 nm, the exposure time is 20 minutes ! And more, if I increase the SQM, the exposure increase also ! Curious no ?
F/D=6.5, ASI183MM, gain=120
On my old laptop Toshiba Portege R930, the two USB port may be disable into the BIOS and run as USB2.
In order to use a QHY294C, I set up the USB3 mode. The camera is recognized with lsusb. When I lauch Ekos, I have to setup optical trains. The telescope are created into the database. But when I want to create a new train, back to the desktop after a few seconds.
I join the log. I don't know who's to blame, the laptop or Ekos.
