Set the calculated FOV and you will be fine. Otherwise astrometry does blind solving. This takes lots of time

This totally incorrect.
As I already stated in this thread EQ6 TTL voltage is 5V not 3.3V! I do own it and I do use it, really, with 5V TTL USB-serial converter. It's ! EQ8 uses 3.3V (you own it right? what cable/converter do you use? is it 5V?) BUT it accepts 5V on RX input. This means it DOES NOT transmits 5V TTL levels on TX output. No level shifters are required for any mount as far as you use proper FTDI converter /cable - 3.3V OR 5V. If you use a converter/cable which does not much your mount's TTL levels you HAVE TO use level shifters. But why would you use such a converter/cable?
Please let's keep it clear and transparent. Otherwise ppl will ruin their mounts with inaccurate information on voltages.

No need for apologies whatsoever 
It's all about security of our hardware, because using inappropriate signaling voltage might be destructive for mounts' controller board.
For clarification and making sure that we are on the safe side I have just reviewed tech specs of Skywatcher mounts. The conclusion is:
- EQ6(Pro) and (H)EQ5 - expect to see a minimum 4V active high signal, lower signaling voltages will not work - use TTL-232R-5V cable/converter for these mounts
- AZEQ6GT, EQ8 - have a 5V tolerant 3.3V signaling interface, so both 3.3V and 5V active high signal will work - use either TTL-232R-5V or TTL-232R-3V3 cable/converter for these mounts
Take a look at example cables and converters using FTDI chip here:
www.ftdichip.com/Products/Cables/USBTTLSerial.htm
I personally love ready to use USB cable with build-in converter like the one on the image below. You just need to finish it up with a plug matching your mount.

What do you mean by that? You're supposed to set FOV manually. It is EKOS that calculates exact FOV based on you camera and telescope. I believe that this is the origin of you problems related to plate solving.AradoSKYindi wrote: In EKOS, I used 180’ x 180’ as my FOV.
Your camera settings will be read from the camera, so no need to configure anything. Your telescope settings (apperture and focal length) need to be set either in EKOS (mount tab) or INDI panel (options in mount tab).
After you set it up correctly take a look at FOV displayed in the EKOS Align tab (the one you use for plate solving). Verify the value using FOV calculator e.g. astronomy.tools/calculators/field_of_view/
If the values differ significantly you're not configuring your setup correctly.

Call it whatever you like. Skywatcher interface is technically UART TTL, which is serial interface.
Just take a look at this link
eq-mod.sourceforge.net/eqdirect2.htm
You can connect it directly to another serial device and that's all you can do. You cannot connect it to USB. If you want to connect it to USB you need serial to USB converter, which supports UART TTL voltage level.
I don't thing the TTL voltage level varies between Skywatcher mounts. At least you're wrong regarding EQ6, which I use personally. It is TTL 5V. The same for EQ5 and EQ8.
The only difference is the plug on the mounts that is different - either RJ11/45 or DB9.
Could you give me a specific case of other TTL voltages and plugs other than mentioned above. Sources supporting these would be just great.

Rob, great work! I'm really impressed with your scripts. Incredible amount of work put into it and lot's of research to build it up and fix the issues.
I have just gone through all the 17 pages of this thread and now I'm much closer to releasing Astroberry 2.0 with Raspberry Pi 4 support.
... for those of you that don't like it - your mileage may vary - there's plenty of other solutions for you to choose.

This is correct. You just need to connect the mount directly with Rpi. Any USB-serial converter will do. Just make sure it is 5V compatible.

You don't need GPS to set your location. The primary functionality to handle it is located in KStars/Settings/Geographic.
However if you want to use your GPS you need to remember to set it up correctly in KStars/Settings/Configure KStars/INDI - look at Time and Location section and select GPS updates KStars.
BTW. these has nothing to do with Astroberry per se, it's very normal and that's how KStars/Ekos work.
Clear skies!
