It seems that the second link would be quite useful. So we're back t the game ;-)

There's really bad news on this driver. Adafruit provides only python library for this board and no c++ library is available that can be used directly. As the result a driver for this board needs to use low level PCA9685 driver (which basically means writing everything from scratch) or bind python library into c++ code (which reuses the library but still requires lots of coding).
In summary, for now a stepper focuser build on Adafruit Motor HAT can only work outside of INDI, controlled with python scripts released by a vendor. Integration with INDI will be possible if c++ library is available for the device.

I think stretching should be just fine. It's all about resource intensive raw to fits format while plate solving or focusing which require fits format.
I'm glad it works for you. Clear skies!

1. For desktop mode you can use standard Ubuntu Mate functions to change language, region etc... (System Settings / Language Support). There's no language setting for web interface.
2. No need for swap file for PHD2 or Ekos. Swap file is not recommended on RPi3 at all due to it tears down you microSD very quickly. However with only 1GB of RAM imaging with DSLR might result in not enough memory in RPi3 (convering raw files to fits takes lots of RAM). The solution would be a swap file. But you have been warned ;-)
3. There must be some kind of issue outside boundaries of astroberry server. Have you recently done rpi-update? If no, try it first and let me know if the problem persists. I might add CCDCeil in the next upgrade
4. I will add Linguider in the next upgrade
5. PHD2 is from PPA and will be updated with standard system updates.

You're welcome!

Version 1.0.3 of Astroberry Server is available! No need to download full system image. Just run astroberry-update and then astroberry-upgrade on the last stable download (1.0.1).

Additions and updates:
- Planetary Imager updated to version 0.6.97
- Skychart / Cartes du Ciel added (no additional catalogs installed)
- INDI Web Manager added and integrated with noVNC
- Nginx reverse proxy added for noVNC ( astroberry.local/desktop/ ) and INDI Web Manager ( astroberry.local/webmanager/ )
- Welcome page added ( astroberry.local )

Fixes:
- wlanconf-gui updated to display available networks

NOTE: You should not upgrade if you customized your system. In such case you need to wait for the next full release (1.1.0)

Thanks

GPSD returns offset based on the timezone configured in your operating system (the one your GPS is connected to). Anyway INDI is not using offset information at all and your mount driver uses UTC time. The offset is used by KStars to set your skymap view properly. You can sync your time both ways - device to KStars or KStars to device (see KStars configuration). You can also disable syncing and that's probably a fix for your issue. Why would GPSD return other offset than your operating system? I have no idea, because as Jochym said it uses standard system libraries. No custom magic whatsoever

Hi Rob

I'm glad you like it. Such appreciation words make great fuel for my development engine ;-)
I'm aware of MQTT, but never used it. It should be pretty much easy to translate INDI information for publishing over MQTT. As I understand it's all about publishing info which is already in portable XML format. I'm not clear how it might be used though... I understand how it's used for IoT but here I'm not sure. INDI as a publisher or as a subscriber or both. What are possible use cases and scenarios? Could you share some ideas on architecture you imagine?

I assume that there are many ways to approach this. For example in astroberry focuser I assume that focuser always stars from 0 (maximum inward). As the result it must be parked from whatever position to 0 at the end of a session. Another thing is making sure that it does not exceed maximum steps allowable for a device, which is device dependent. I have used various focusers and I noticed that they rarely travel more than 20000 steps. So in astroberry I hardcoded this value as a maximum. In reality focus point never reaches this value. At the first use of a focuser I manually push it to mechanical maximum outward and remember the value or save it in focuser preset.
All of the above applies for absolute position focuser, for repetitive focus position for each session. If you don't care about absolute position and move a focuser manually close to focus point and then use stepper motor to get precise focus you just need a relative focuser which can travel both ways. However the latter approach makes it hardly possible to define min/max for focuser travel... because you don't really know your starting position. In such the case only min/max hardware sensor can help. None of focusers I know is equipped with such a sensor. This loops me back to approach no 1.

I have just added system upgrade script which lets you upgrade without need to download full system image. Just start terminal window and run astroberry-update and astroberry-upgrade. It will upgrade your system to the latest release of Astroberry Server. See Changelog for details.
