Hi,
I would like to control Meade LS 8-Inch ACF (f/10) Advanced Coma-Free Telescope with Indi Ekos. This telescope is based on Autostar III version.

Anyone knows about this?

Thanks in advance!

Should be, just use the LX200 GPS driver.

Ok thanks Knro for the reply. I am going to buy this telescope as soon as possible. The advantage of single switch alignment attracted me most. If all the options can be controlled by the indi it will be superb for me. Do you know anyone used this scope with Indi or do you guess any issue may raise up?

Regards

Well it uses LX200 command set so I don't see why wouldn't the driver work. Only actual testing can reveal any issues.

Hi! Finally I bought the telescope and today I tried it to run by Kstars/indi, but failed. Please see the attached pictures.
I tried LX200 GPS library.
lsusb output: ST-Ericsson is most probably the telescope. because when I plug out the telescope usb it disappears.

Please would anyone explain me why indi is showing such errors? What can I do now to control the telescope using kstars?

Thanks in advance!

First, check if you have /dev/ttyUSB0 , then as indicated in the FAQ , add your user to the dialout group and restart:
sudo adduser $USER dialout

Hi!
I followed the FAQ but failed to work it out. Dialout user command does work. but ls -l /dev/ttyUSB0 shows: cannot access /dev/ttyUSB0: No such file or directory.
Note that LS8 connects with pc via Print port to USB cable.
Any further suggestion?

I'm not sure if ST-Ericsson is a USB Serial driver. Anyway, we can see what happens if you unplug it, then plug it back, and type
dmesg | tail -n 20

Post the output here.

To me it looks like not recognized USB port. What the bluetooth stuff is doing in the log?
Do you have a serial over BT device? What do you meen by "printer port"?

Hi! I don't have any serial over bluetooth device. I have been using Rpi3. The telescope connects through printer usb connector cable. I have attached a picture of it. This time I have connected a TPlink wifi adapter and the Meade LS8 in USB port. See the results:

From Meade download page they offer PL2302 driver, but then the 0x04CC vendor is ST-Ericsson and the Kernel cdc_acm driver does not recognize it. I think maybe the kernel needs to be patched to support this, but I'm not sure, I'll investigate later.
