Michael Hamilton created a new topic ' KStars Star map pointing enhancements' in the forum. 18 hours 55 minutes ago

Hi ,

I find using a laptop with a track pad (which is my default in the field) is really difficult to point accurately to objects on the map. Some of this is due to the large X that does not help with accurate pointing. Is it possible to change that X back to a arrow to improve accuracy with pointing? An alternative is a "snap-to" feature to snap the pointer to the most prominent object in the very close vicinity. This would make browsing the map in the field for potential targets easier.

Thanks for a great product

Hi Lunas
I am going to try again tomorrow cos I hate to let these things beat me. I am also hoping that the improved FITS stability in the recently released KStars 3.3 will sort out my problem although it may be different to yours. I hope that you find a solution.

Hi,

I tried to use the polar alignment assistant on the weekend for the first time as I normally use Sharpcap PA. I got through the three solves to the point at which the fits image with the correction vector appears. As this is quite small I toggled to full screen at which point KStars crashed. I was not game to try it again as it just wastes valuable AP time and I had already done a SharpCap PA so I knew that I was OK. I will try again when I have more time but it seemed that toggling to full screen caused the crash. I am using an Odroid XU4 with 4 gig ram so don't think that it is a memory issue.
Cheers

Sorry the system did not like the link so here is the name of the HUB I just mentioned
VOLANS Powered Aluminium 7-Port USB 3.0 Hub VL-HB07

I am using a 7 port USB3 12 volt powered HUB. It is mounted inside a case with 3 of the ports accessible on the outside. It has never given any trouble and works perfectly with linux systems. (Odroid XU4). Used outside in heavy dew many times.

Hi,

I am running a Odroid XU4 in my setup. No problems at all. I have it in one case with dew heater, motor focuser, USB3 hub, and 4 external 12 v outputs and a 2 TB hard drive. I have a voltage regulator stepping down the voltage to 5 volts for the powered hub and the Odroid. It will run off a single input 12 volt supply either mains or battery but use a large battery especially in cold weather. It runs headless using Team Viewer as we had problems with real VNC working reliably with the Odroid (no idea why as its great in RPi)
The only issue with the Odroid is that is produces a lot of heat so a thermostatically controlled fan option on the heat sink is a must. I used the large passive radiating heatsink but in the end had to put an external fan on the case to get the air circulating. Performance is significantly faster than RPi.
Cheers

Michael Hamilton created a new topic ' Astrometry solver problems - solved' in the forum. 4 weeks ago

I have recently had some persistent solver failure and time out issues with my Astrophotography set up. These have been driving me nuts but hopefully I now have them sorted so I thought that I would share some tips. I have KStars /EKOS/INDI running under Ubuntu 18.04 on an Odroid XU4. I use team viewer for headless operation on a windows laptop. Startup KStars , EKOS and INDI on the odroid then use KStars remotely through the home network on my PC inside. In the field (away from my home network) this setup runs through a WiFi extender as a hot spot. I have had some intermittent astrometry solving issues but generally these have been good for the last few weeks. A few things that I have noticed that have been consistent are a failure to solve any image using the offline solver on the odroid or trying the ANSVR server on windows when using 4X binning with the ASI294. I generally find 1Xbinning works best in the field.
Recently I have tried a load and slew to test out the astrometry as the weather has precluded doing testing outside but nothing would work, the solver either failed straight away or ran through all of the astrometry fits and then timed out (even using 500sec time out settings) or failed. ANSVR also ran though and failed (failure to get job ID). Interestingly, trying to use the on-line astrometry solver timed out on upload which has never occurred before.
Yesterday I had a clear night and managed to try all sorts of permutations to get previously saved FITs files to solve.
Most of my saved files are 60 -240 sec duration . After a lot of trial and error I have found the following settings worked really well and now solves quickly (within 20-30 secs using the offline solver on the odroid which also works well remotely under kStars for Windows.
So, in the astrometry.net solver options I ticked WCS, overlay and jpg upload. In the solver options I unticked no fits, ticked resort and no verify and unticked parity. Unticked use scale, ticked auto update, units aw and recalculate FOV before using the solver, downsample X 10 (I tried 8 times which took much longer and X4 timed out so this was important), I also unchecked use position (this appeared important using load and slew, less so for capture and slew).
I also deleted the astrometry FIT files that were not needed for my FOV especially the really big ones as these seem to increase the chances of timeout and are not needed for the majority of user scenarios.
I was really surprised that I needed to use X10 downsampling and removal of the "scale" and "use position" options seemed counter intuitive that this would make things work.
Since using these settings I have not had a problem. Solving is consistent and fast.
I am using NEQ6 mount (EQMod) with ASI294MCPro and ASI120MM as guider with OAG.
I thought that I would post my settings for anyone out there having similar problems using similar gear to try as some of them that seem important in getting things working for me were the last things that I thought would work.
If anyone can explain the logic of why this works so well I would be really interested. Otherwise it is posted for others having similar solving problems to try with no guarantees that it will work for you.
Clear skies everyone!
Mike
Oh and as always many thanks to Jasem and everyone else involved in this tremendous application. Keep up the good work!

Hi Ron,
Go to Configure KStars in the KStars settings menu on the top tool bar
Go to the FITS tab
There are a selection of features there including auto debayer. Uncheck the box and you should be good to go.

Hi,
The EQDir cable is all you need. Straight from serial connector of the mount to USB on your computer. Thats why so many people use it cos its soooo easy.
BTW just a precaution - don't hot swap a serial cable to mount. Always switch off before plugging/unplugging. I blew a board once doing this, you only do it once. It's easy to forget when experimenting with cable/adaptor configurations.

Hi,

OK so I have just tested your setup using a serial to USB adaptor like the Aten. I know that this works as I have used it to update the firmware on a few handboxes (sometimes the chipsets in the cheaper ones do not work). I can also confirm that this setup will not work as a direct connection from mount to RPi, you have to use the handbox. I am not sure of the differences between the EQDir cable and these generic serial to USB but the EQDir is designed specifically for this purpose whereas the others are not.
Maybe others can help in defining the differences but my feeling is that you may be wasting your time trying to get the Aten cable to work when really the answer (certainly in terms of a reliable connection) is the EQDir cable.
Sorry I don't have a better answer.
Good luck
Mike
