How to force Telescope Simulator to always track #40433
Quick background: I don't have a go-to mount but I use KStars/Ekos to visualize where the scope is pointing after a plate solve using Telescope Simulator.

The telescope simulator's icon (bull's eye with cross hairs) syncs after a plate solve but then immediately starts drifting eastward. To stop it I have to click on KStar's menu: Pointing -> Engage Tracking. The annoying thing is I have to Engage Tracking quite a lot. I tried INDI control panel settings but found nothing there that had any effect. There could be some setting in KStars that I am unaware of.

So this was just a minor annoyance until recently when I began doing photometry where AIRMASS (in the FITS header) is important.

I just discovered that when Ekos captures a frame it writes these keywords in the FITS header: OBJCTRA, OBJCTDEC, RA, DEC, and AIRMASS. The problem is that the values are coming from the Telescope Simulator, not the last Plate Solve! That means that if I don't engage tracking in KStars and then start a 10 frame capture sequence, the position of the object changes with each new frame.

Is there a way to permanently turn on tracking?

Thank you.

When you start Ekos with the simulators simply go to the Mount tab and enable tracking there.

I'll take a look at it again. Last night I am 99.9% positive I did that but still the simulator was very eager to switch off tracking after a plate solve.

Perhaps it is the type of plate solve I do: "Sync".

I would have been very surprised if you hadn’t done that. FWIW, when a sync is done, the mount is informed at which coordinates it is pointing and it continues tracking.

You know, I was just thinking, I tried to engage tracking from INDI control panel. Tonight I will try from the Ekos mount tab.

Yep, that was it, the Mount tab in Ekos. Saves me a lot of work repairing FITS headers!

Thanks.

Great! I'm glad you found the reason for tracking switching off all the time.
