iEXOS100 Mount Tested With PMC8 Driver #43716
Hi,

I'd like someone to clarify the iEXOS-100 connection to computer.

In the mount manual there is an image showing miniUSB port. In the indilib Devices/Mounts/Explore Scientific PMC-Eight/Requirements section, there is a statement that says we have to use SPECIAL USB Serial cable and link to the solution incorporationg a FTDI USB<->Serial cable.

What is the purpose of using this SPECIAL USB Serial cable if we already have an USB port in the computer and mount itself?

Clear skies!

I don't think this applies for direct usb connection. The driver documentation should be updated. Were there models before that use serial to usb cables? if yes which ones? maybe we can post photos of the model that requires this FTDI cable mod?

It is pretty obvious which models need a USB->Serial adapter and which accept a mini-USB cable. The iEXOS100 is the only one I know of that takes the mini-USB at the moment but I haven't looked at this for many months perhaps ES changed something.

iEXOS100 Mount Tested With PMC8 Driver #43727
Thanks guys for quick reply.

Let me clarify: I'm in process of decision whether to buy iEXOS-100 and get rid of my EQ3-2 SynScan Goto. I've just bought QHY5L-II-M and QHY miniGuideScope and planning to buy TS71SDQ Quadruplet, the only thing remains is the mount.
For my amateur astrophotography I use INDI server on Ubuntu Server 18.04 on RPi2B+ with WIfi dongle. As a client for INDI server I use macOS 10.15 and Kstars 3.3.6 and like to stick with it, as a macOS-only user (no plans for VM/BootCamp with Wndows).
My hardware setup is: SW 150/750 on EQ3-2 SynScan Goto as EQMod Mount via PC-Direct mode and Canon 700D without IR filter.
I really like the iEXOS-100 mount because of it's light weight (I have to carry my gear IN and OUT everytime coz of robbing neighbourhood) and for belt-driven mechanism.

The thing is: will I be able to use iEXOS-100 the same way I did with EQMod Mount?

All the best!
Patryk

The PMC8 driver has not seen much testing and I would consider it maybe beta at best in stability. The EQMOD driver on the other hand is one of the best developed and maintained drivers. I would look at another EQMOD mount if the functionality and stability of EQMOD is important to you.

And to be honest I don't consider a mount being light a good measure for an imaging mount - you want stability.

Hi Mike,

And to be honest I don't consider a mount being light a good measure for an imaging mount - you want stability.

Yeah, I already know that... BUT I have to consider:
  • my spine injury (doctor said I'm not supposed to lift more than 25kg)
  • neighborhood (guys wandering around at night, stealing things)
  • I'm low on budget and can't afford HEQ5, worth in Poland ~1150$ (it's heavy BTW
I'm trying to find the best solution, and I find iEXOS-100 is the way to go, as the guys from espmc-eight reporting successful 10min exposures.

I think that swapping my old, good EQ3-2 SynScan GoTo for iEXOS-100 is the right choice, as my mount isn't capable of guiding anyway.
What do you think?

I understand the physical side is certainly a big factor.

I only had the mount a couple of nights to check the INDI driver compatibility.

No really experience imaging with it so you'd have to check with owners.

It is a really tiny mount - but if it is all you can move then not much of a choice I suppose.

iEXOS100 Mount Tested With PMC8 Driver #47277
Hi,

I finally managed to make my iEXOS100 work with INDI. However, only serial connection seems to work. For UDP, there is probably no reply from the mount and with TCP there possibly is a reply, but with too great delay. It seems to be a problem of the mount, not INDI.

I also have some problems with the alignment synchronization of the mount. I started at a (virtual) polar position of the scope, but slewing it anywhere else just pointed to meaningless directions, such as below the horizon. The geographical location was set both via the INDI control panel and (I suppose) also Kstars. But both Kstars and SkySafari just turned the telescope to wrong positions (I tried North, South, West and East) as if the sky was tilted for the scope. I do not know about the time - it was correct both in SkySafari and KStars, of course, but maybe not in sync with the mount? I parked the scope again and switched the mount back to UDP and tried the original ExploreStars application and it immediately started pointing in correct directions. I switched the mount back to serial and connected to INDI again and now it seems to have kept the right positioning. But what have I done wrong and what should I expect next time? How to make the mount in sync with INDI or reset its position? I always start in polar position of the scope, but it does not seem to be enough.

Thanks for any advice,
Pavel

Perhaps the mounts needs to be aligned first with the HC before it is connected to INDI? All mounts (except for EQMod) require alignment prior to connection.

Excuse me, what is HC?

According to the driver documentation, it only needs to start in polar position and have location and time set correctly. (In the original vendors application, I only did that and it worked.) The location is being set as I can see from the INDI control panel messages. I cannot see anything about the date and time being set, however. I have no idea how the internal motors are being synchronized to the correct position, but I suppose it is being somehow reset to the polar position when powered on...?

HC = Hand Controller.

Perhaps turn on debug logging and share the logs?
