Thank you very much for sharing your shortcuts! And suggestions/ideas.
I am so not used to connecting monitor/keyboard directly to the RPI. Gotta try this.
Interesting.. I should try that screen! I was planning to add USB WiFi later .
Yeah.. I have a feeling that a laptop might be needed after all. Otherwise it's too cumbersome to operate.
How do you power the laptop for a prolonged time?
I guess, 3-4-5 hours wouldn't be a problem. But what if I need longer? 2-3 nights?
I have a 6000 mAh / 12V battery which feeds a CCD cooler and a USB hub which is connected to and also feeds the RPI - this lasts for a long time.
Another 3500 mAh / 12V battery powers the mount - also lasts for a long time.
Another 3500 mAh / 12V battery powers the dew heater - this one lasts maybe 6-8 hours (that's OK - I don't need it ON all the time).
Laptop... Got some random laptop. It's small - the battery will not last for more than 5-6 hours I think. It's 19.5V.
I guess, I need yet another powerbank for the laptop and I will be all set up for 2-3 nights of shooting.

I am no that familiar with Linux. How do you set keyboard shortcuts there?
As to the 1080P monitor - it looks nice but it limits your distance to the mount/rpi to the length of the HDMI cable, right?

To control it, I have been using a tablet, stylus and a wireless keyboard with trackpad like the Logitech K400 Plus. I try to make good use of keyboard shortcuts, many of which I've customized and labled on my keyboard. Away from the mount I use VNC on my phone to monitor things over WiFi with a more powerful WiFi USB adapter on the Pi for better range.
However I am going to move away from the tablet soon since I no longer rely on the tablet touch screen thanks to the keyboard. Instead I am switching to this portable 1080p display . It can accept non-standard resolutions, and is low power with a nice image, and you may find it on amazon or elsewhere.
All in all everything works well, consumes little power, and doesn't mind the cold. So I have no immediate plans to use a power hungry laptop.
I got used to the dark theme. It's pretty good.
A couple of issues:
-- every time I go to indilib.org/forum.html (after the browser was closed/opened) I have to log in again even though the check-mark "Remember Me" was checked.
-- I don't get notifications when someone posts to topics I am subscribed to (very seldom I do)
-- When I enter some text in Quick Reply and then go to the full Editor the text gets forgotten
-- When I want to attach files there are two drop-down boxes which are impossible to read
KStars/Ekos is so mouse oriented... All controls are so tiny.
I find it next to impossible to operate on a touchscreen tablet (and I have a small 7" Nexus 2013) which is connected to an RPI via VNC.
A laptop is much easier to operate but the battery life is an issue.
How you guys operate KStars/Ekos while away from power outlets?
Please share - thanks!
(I wish there was a tablet friendly version similar to Ekos Live)
great tip - thanks! exactly what I needed instead of Live View

In fact, you can even set this Framing Image to display full screen which is quite helpful for manual focusing but would also be quite useful for your purposes.
I didn't go as high as 800 but tried 560. Again, it works at 8bit.
I'll play some more tonight...
Tonight was clear despite the bad forecast so I gave my setup a try.
Was using a quite recent nightly build of Windows client. Two CCD cameras.
Let me start with the problem first.
-- Live View doesn't work for ZWO ASI1600MC when in 16bit mode. Getting white frames with some noise.
Preview (16bit) works fine. Live View in 8bit works fine.
Secondly, a couple of issues I had before got resolved (or almost resolved)
-- FITS histogram/image look much better now
-- Polar Alignment now works (it wouldn't refresh images before). Now it refreshes but stopps refreshing after about 3 min saying that it was done with the procedure (I didn't double check this one).
(Oh, great! KStars just crashed! I was shooting the Owl Nebula at the moment. It was running for about 4 hours. I did many different things with it. Just crashed while I was writing this post (same PC)).
Tried today with a new nightly build (Windows client). Worked! i.e. it was refreshing.
But after about 3 min it stopped refreshing saying (don't remember exactly) that the sequence was done...
I didn't have enough time to align.
Tried today with real stars. With Windows client. Looks much better!
However, Windows version looks differently from RPI.
In Windows client, when unstretched, image/histogram shows full scale from 0 to 2^16 (for 16bit image) - that is great.
In RPI it's clipped from the right.
How close the builds for windows and Linux in terms of updates are? I think my windows version is just a couple of days newer.
Couldn't test it with stars - shot cloudy sky instead.
Everything was running on RPI with latest nightly updates.
Still think it should show more info to the right
