OK, so I found I could start the driver using the webmanager and the cantrol window would pop up with the FCUSB set and the focus module was available. Nice.

Would be even nicer if the driver was given in the EKOS menu.

I meant StellarMate not Stellarium!

I'm running Stellarium remotely from a Mac. Stellarium has the FCSUB driver but I can't select it from the Mac in order to configure Stellarmate. I can run the server on the Mac but it doesn't do any good - not even to provide a selection in the focuser drop-down menu. How can this work?

Thank you Peter,
I just discovered that the FCUSB driver is included in StellarMate but looks like I have different problem. I use Kstars on a Mac and connect remotely to a StellarMate that is connected to the telescope. I see the FCUSB driver selection on the StellarMate but its not available on Kstars on the Mac so I can't select it for remote setup. How do I set this up?

Can you tell me if you now have JMI motofocus and FCUSB and INDI working on a RPi?

Greg Beaton created a new topic ' FCUSB worth getting to motorize focuser?' in the forum. 3 days ago

I'm thinking of motorizing my focuser - Explore Scientific Crayford 2" focuser. It looks like I should get a JMI MFESC3 and replace the controller with Shoestring FCUSB. And the shoestring controller has a driver for INDI

Is that right? Or should I get something else that someone can recommend?

Then I restart the alignment process without touching the telescope but asking it to do it to the east. The telescope returns to its original position... but now it is more out of adjustment than in the beginning....


Yes, this is the same problem I get. I have to park/unpark before each use.

No, I park facing the pole. The PA method definitely needs you facing the pole and within 1 degree for successful plate solving. So last time I polar scope align first and then 1-star align and then park - gave me 5' accuracy according to Ekos, then did Ekos PA and got 9" accuracy. I suppose if you park with DEC =0 then you could move it to 90 and it should be ok. It kind of doesn't make sense that it needs to be in park first as long as its point to Polaris, but a couple people just found they had to do that.

Yes, you need this "EQDIRECT" electronics box inline with the mount - part of the "cable" people speak of. You have to make it yourself or buy custom - I forget where.

See my post above. www.indilib.org/forum/ekos/2820-eqmod-alignment.html#20981


I re-read a few things and yes, EQMOD says they can't guarantee reliable operation with the HC because its undocumented. However, it is documented (in my synscan manual). I'm not sure why they say that and makes me wonder to what interface spec they are working. And I wonder who wrote the INDI EQMOD mount driver and who's interface they are working to.

Ihoujin wrote: It is a good idea to clear the alignment model after the PA procedure because adjusting the ALT AZ bolts will invalidate the model.
That being said I think it is done automatically for you, but in not sure.


Good point. I think it does that at the start. I remember seeing that message. I have to check now. But I don't really do alignments anymore per se. I goto a target after PA and then do a plate solve, slew&sync. This also works great. It automatically retries until its accurately aligned. My targets are dead centre!

TallFurryMan wrote: I have a question about PA as done by Ekos: does the PA procedure sync the mount at the end of the solver step? This might explain why you need to park to somehow reset the adjustments, wouldn't it? I still have to run a successful PA via Ekos myself.

-Eric


I don't believe so. It just leaves the mount rotated after the PA sequence.

I just lost my longer answer so the sort answer is that if you remove the HC you have to replace it with some motor driver electronics. I’d rather keep the manufactures stuff.

Thanks for the suggestion. I tried it last night again and it worked perfectly! I just made sure the mount was tracking and that I start from Park.
