Maybe this is already a feature of KStars/EKOS but an easy to use framing tool as part of planning targets would be nice. I currently use telescopius.com/ to do my framing. I'll filter and pick a target then get the FOV framing based on my equipment details. I can then drag the FOV frame around to get the best framing. Then I usually add the RA/Dec of the center point as a custom object to KStars to use for my session. Be nice if this could be done quickly inside KStars/EKOS.

Tunafish replied to the topic 'PA routine with RPI4' in the forum. 4 months ago

I suspect that everything on the RPI4 is slower than on the MBAir. I use a QHYCCD QHY5-III-178C for my guide camera and use it do PA on my RPI4 4GB with Astroberry. You have Update PA Error checked which can be very compute intensive so the recommendation I have seen is to use 2x2 binning to reduce the image size. Looks like your camera may be 9M pixels while mine is 6M pixels. I use 2x2 binning with the Update PA Error checked at a 0.5 second refresh and it is usable. Not amazing but usable.

I found that KStars continued to crash for me if the summary screen preview was enabled. i believe it still needs to do same image processing as the FITS viewer to display in the manager window so continues to eat memory over the night.

Looking forward to hearing how enabling the 64bit kernel works since KStars will continue be a 32bit application unless rebuilt as a 64bit one.

I know you said you had the latest version of Kstars/EKOS/INDI but there was an issue with KStars 3.5.2 where the Fitsviewer would run out of memory and crash KStars after a while. I have the latest Astroberry which is still at 3.5.2 and I know that if I leave FITS viewing on while doing acquisition then KStars will randomly crash at some point in the night. I have seen this directly on occasion where a debayering  error pops up and then KStars crashes. INDI keeps running in the background.

This was supposedly fixed in 3.5.3 ( Fitsviewer crashes when imaging with Altair Hypercam 183c - Kstars 3.5.2 ) so if you do have 3.53. then this should not be the issue. If you're on 3.5.2 then turn off the FITS viewer during acquisition and give it a try.

I've always used Win32 Disk Imager but assuming Balena Etcher is quite similar and creates a single partition that is only the size of the original 32GB SD card then you can use the raspi-config tool to expand the filesystem out to the full size of the new SD card.

Personally, I've kept my boot SD card on the smaller side at 16GB. I use a USB3 500GB SSD for the mass storage. I use symbolic links from the astroberry home directory to the SSD for large sets of files like the plate solving files and my actual imaging. This lets me make and save backup images of the SD card to my PC. It particularly comes in handy when Astroberry/KStars/Ekos is updated and you go to do a night of imaging and find out the update broke something. If you have a backup either in an image file or on a spare SD card you can quickly roll back without losing a night trying to figure out what broke.

You can do this with your 128GB SD card too. Backup/Restore is just slower and the cards are a little more expensive.

One way to work around this (at least for the cool down, I haven't tried to create a sequence queue for warm up) is to create a capture sequence queue that steps down through the temperatures and then does a capture at that temperature. So, for going from 20C to -10C I have a saved capture sequence queue with 7 individual sequences with a 5 minute single capture in each. First is a capture at 20C with force temperature selection at 20C. Then one at 15C etc.. down to -10C last capture only needs to be short like 1 sec. I just saved the sequence queue to a file and load it at the start of a session an reuse it. You can delete off the front or back of the queue if you want to change the range, say go 15C to -5C instead.

This way the camera is stepped down 5 degrees at a time and sits at each temperature for 5 minutes taking an image. I tag the images with a file name like 'Cool-down' so I can delete them later.

I found I had a lot of problems getting my neo-6m to work when using Kstars. Ultimately for me it turned out to be a USB3 interference issue. As soon as I had my USB3 QHYCCD camera connected through a USB powered hub the GPS would never lock. Not sure if you have an RPI4 and this issue but if you do you could try extending the serial cable so the GPS is a couple of meters away. If you're not using USB3 for any thing then you can probably ignore this comment.

Not sure if this is helpful but you can use the Toolbar Settings in KStars to add Park and Unpark buttons to the main toolbar. I didn't see Home as an option though. They can then be clicked from any Ekos tab.
 



Having said that, although I like the new Polar alignment tool it would be great if you could select an option to automatically return it to the starting position once you click stop or done. Whther that is parked or somewhere else.
