INDI Library v1.7.6 Released. (27 Feb 2019)

First release of 2019 comes with quite a few new drivers across the board along with significant performance improvements to INDI camera and live streaming performance. Many drivers received significant updates to improve performance & stability, while a few were re-written from scratch to be in line with INDI standards. Here are some of the highlights:

Stellarmate - is it better to run on MacBook or on the Pi ?? was created by suvowner

1. So is the best practice to run kstars and ekos on my MacBook or is it best to launch kstars on the pi and control it through the vnc ??

when I tried it running on my MacBook, the focusing seemed pretty slow and a bit unstable, in this case are the image files taken for focussing being transmitted over the wifi to the ekos on the MacBook, if so this it seems it would be a lot slower than having those files go to the pi through usb2.

2. will ekos pull the gps location and time from the gps puck built into my Ioptron Cem-60 ??

3. if I want to do plate solving at a dark site, with unreliable internet and run ekos on the pi and control through vnc do I have to download astrometry files onto the pi, or are they already there ??

4. my cem60 has a built in non powered usb2 hub on the dec saddle, should it work ok to connect a powered usb hub to the pi and then the usb2 hub built into the cem-60 mount to the powered hub ??

5. could I use the polar alignment tool to do the alignment while using the pole master as the alignment camera ???

6. can ekos do dithering without setting up a guide camera and scope ?? since my cem60 is the encoder version when imaging at F/2 with my C8 hyper star and I don't really need any guiding, simplifying and speeding up the setup time, but I still should probably dither.

7. any other tips/tricks or common issues I might need to know ?


thanks

I've tried all - the one you didn't mention is what I find to be best. The PI (not ktars running on it) but the SM server. Then run Kstars/Ekos on OSX and it will connect to the PI (server) remotely! I'm doing this but connecting with windows. (I love OSX but sold out of my Macs for astro gear compatibility).

Yes you could use the pole master camera for alignment tool. Yes you can dither, hub? (I prefer powered) but you'll have to test it and see. I use a powered 3.0 hub on the mount(added).

Tips... don't run kstars on the pi. Run the server. Allow the more powerful computer run Kstars/Ekos. Focus is quite quick, you can do them local or remote and you can save time and data transmit time by checking SUBFRAME

1. Run the INDI server on the Pi and control everything by running kstars/ekos on your mac. The Pi is pretty slow if you try to do everything (kstars, ekos, phd2) on it. If you want to use VNC to remote in to something to run your imaging session, use something more powerful than the Pi.

2. Yes. I have a CEM60 and it gets the coordinates from the mount's GPS. Make sure you set the option "Mount Updates Kstars" in the INDI preferences.

3. The Solver options allow you to download all the index files you'll need for offline solving. It will recommend which files you need based on the FOV of your configured scope.

4. A powered USB hub connected to the Pi is what I am doing. Works great.

5. Just use the Polemaster. No need to use the PA tool.

6. The only dither options I can find are in the Guide module, so it appears dithering only works when you are guiding.

7. Have fun!

They will both do the same job, however, I have my Raspberry Pi sitting on the mount exposed to the weather and the Mac inside monitoring things, when required, sitting inside out of the weather.

It is much cheaper to replace the Pi.

INDI can plate solve locally so no need to have an internet connection.
INDI can also assist with Polar alignment.

I'd have to say that I've found it less frustrating to run as much as I can on my MacBook. The Pi will run longer, since I've got a sizable sealed lead-acid battery for it, the mount, and the camera, but I run into endless gripes with plate solving failing, or the UI failing to respond for 15-20 seconds at a time, and the like. That said, I imaged with a DSLR for a good year using the Pi and remoting into it with VNC, so it certainly can be done.
