I’m generally enjoying very good results from Linear 1-Pass autofocus on various scopes (Newtonian, Maksutov-Cassegrain, and Refractors) using the ZWO EAF. I also have a joystick, set up to use a couple of buttons for focus-in and focus-out steps. The Indi Control Panel step setting is always set to zero when I start Ekos, so the buttons do nothing until I change the step setting from zero. It would be great if this new value should be stored for the next session.

I’ve just installed a fresh image of AstroArch 1.8 and am very impressed - well done Mattia!

Just installed AstroArch 1.8 and I am very impressed! Three features have really elevated this new version for me - installing the image directly on my favourite Samsung 256GB Fit Plus USB stick was great; having a working local HDMI display option as well as WiFi hotspot noVNC remote desktop was super, and finally the speed of the GUI has solved completely the issue which started this post topic - both the virtual handset and joystick give instant manual control of the mount!

The GOOD news - I have had a successful week using KStars 3.6.9 and INDI 2.06 with two very different sets of equipment (powered by a Raspberry Pi 4 and a Raspberry Pi 5) capturing comet 12P/Pons-Brooks!
The issue in the subject line refers to the manual steering of my two mounts, Sky-Watcher AZ-EQ5 and AZGTi, which both use EQMOD drivers. Whether using the virtual hand-controller, or else a Logitech F710 Gamepad joystick, there is a lot of latency (feels like seconds of time) between issuing a command and the resulting action. When capturing a comet, it is easy to steer automatically to centre the head of the comet in the FoV, but inevitably you may want to offset this point in the camera frame to capture more of the comet's tail, or to include another DSO such as in the case last week M101. Fine adjustments in position were difficult and imprecise due to the apparent hesitancy in the manual control. Am I overlooking a polling frequency setting somewhere?

Should I expect to be able to control the focus of a Canon 55-250mm zoom lens mounted on a Canon EOS 600D camera body, and connected to KStars 3.6.9 running on a Raspberry Pi 4 4GB, by remote control from the computer? It's some years since I last used a DSLR with KStars, but I am trying to build a lightweight system with an AZGTi and a ZWO miniguidescope with ASI120MC, the latter mainly for polar alignment. Exposure control and image downloading is working well, but I am not convinced that the controls are changing focus. Are there any special boxes I need to tick to get focusing to move under software control, and how should the physical MF/AF switch be set on the lens? Thanks for any help you can offer!

A question for Nou or other software experts: Does the script have to be run on the device which it will be used on? I have used Nou's script to build KStars 3.6.9 on Raspberry Pi OS 64bit Bookworm on both a Raspberry Pi 5 (8GB) and a Raspberry Pi 4 (4GB). I was surprised to find that the two images do not seem to be interchangable, although I have found that the RPi 4 one does run also on an RPi 4 (8GB) as I expected. Any explanations? Thanks.
