asi-common was removed from source tree yesterday. It is replaces by libasi which is required by indi-asi.

Looks like the package is available in launchpad list (indi-aok 0.8~201910240508~ubuntu16.04.1) but not in a pool directory of the repository.

If it relates to all ATIK CCDs (we know of the 3 mentioned) this would mean it's atik library problem, not the driver itself.

This is really strange.
Sony ICX694 sensor according to datasheet is 2750x2200 active pixels (2758x2208 effective pixels).
Sony ICX694 sensor according to datasheet is 1360x1024 active pixels (1392x1040 effective pixels).

Has anybody noticed any change in resolution of FITS files from ATIK CCDs?

I use ATIK 460EX, it's resolution according to specs is 2749 x 2199px.
I have just noticed that until ~ 4th of September the FITS files have been 2750x2200px (+1x +1y) and after update in the second week of September the resolution changed to 2749 x 2199px.
Apparently the resolution change comes from the update.
The version after update is indi-atik 2.4~201909051842~ubuntu16.04.1
I run ubuntu mate 16.04.1 on Raspberry Pi.

The problem is that the resolution change results in critical problems in calibrating light frames because darks, flats, bias from you library etc have different resolution.

Can anybody confirm this issue?

PS. Similar topic has been already discussed in this thread .

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.
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.
