Re: Slewing behavior: POTH Hub vs Device Hub #ASCOM #iEXOS-100

Bob Trepiccione
 

Hi Jerry,

It seems that AST is the only one that seems to have this issue that I have found.

Sharpcap, backyard Eos, and Stellarium seem to function normally with both. 

There does appear to be somewhat of a lag between button "push" and mount movement with POTH vs Device Hub.  Device hub seems more responsive.

I am connected via WiFi, but I've tried it with a serial connection and the lag is there regardless of connection method.

So maybe it's just an issue with AST itself,  but ASCOMPAD doesn't function with the device hub either. That may just come with the territory, though.

I came to this conclusion while trying to use an Xbox controller for slewing...got it to work with POTH, no go with device hub.

I've attached a pic of the actual message that AST returns...

Hi Bob,

Thanks for your report... This post is very relevant.  So if I can summarize, it appears that the Device Hub does not work the same as the POTH and is in fact, not operational as the POTH as it triggers an exception in AST. Have you tried it with any other ASCOM client program?

Slewing behavior: POTH Hub vs Device Hub #ASCOM #iEXOS-100

Bob Trepiccione
 

I have ascom 6.5 installed. 

When selecting  the PMC-8 driver directly in Astrophotography Tool the slew controls work as expected.

If I choose Device Hub Telescope, AST can connect, park, unpark, but the slew controls trigger an exception error in AST.

Here's the  interesting part...if I select POTH Hub in AST, all controls work.

This holds true for using ASCOM Pad, as well.
Works with POTH Hub, slew controls do not operate when Device Hub is selected...

Any insight from our ASCOM afficienados?

I think this post is relevant to this forum. If not, ease delete...

Guys you can get the exact version back by using the configuration manager and sending the ESGv! Command.  It will return the full version number which you can bounce off of the version number you thought you loaded.

Re: UPDATED FIRMWARE NOW AVAILABLE #ExploreScientific #FIRMWARE

I'm in the same boat as Brian I'm afraid. Can't tell if the firmware took hold on the iEXOS 100 but it still works so that's good! :-) The ExploreStars iPad app reports 'FW Ver: 2.03' but I have a feeling that's what it said earlier before I upgraded. Really should have taken a screenshot to refer back to :-/


Re: iexos-100 slewing is sticky #iEXOS-100

Wes Mcdonald
 

The 100 has the same motors as does the exos2.  The torque is the same.  It’s ability to handle of balance loads is probably the same.  If anything it will be better at it if the scopes are smaller.

Start with a well balanced tube with representative loads and you should be fine when you change things.  Clearly if you put in a 3 pound Barlow in place of an 8oz small eyepiece things are gonna get a bit crazy.

Re: iexos-100 slewing is sticky #iEXOS-100

Thanks for you suggestion. Now that I have realised that balaance is so critical it is much better behaved. I simply didn't realise that small differences had such a great effect so I am now testing balance much more thoroughly. Fingers crossed that it stays like this.


Re: iexos-100 slewing is sticky #iEXOS-100

You could use a flip mirror diagonal, I think it might solve your balancing issue. What do you think. Luc

Re: iexos-100 slewing is sticky #iEXOS-100

Thanks. Good point, well made. I am beginning to appreciate that. Having read the post, I tried changing the eyepiece and was surprised at the difference it made. As you ay, smaller motors need need more attention because they work within stricter limit.

On 27/07/2020 15:49, Joe Izen wrote:

I ran into the same issue. Balance is a critical issue for the iExos100 that requires a LOT more attention than for my C14 and 127mm refractors on much larger Orion mounts. The problem is that a DSLR+ Flattener or a diagonal plus 2" eyepiece and possibly a barlow is a significant fraction of the weight of the whole telescope.  Changing from visual to photographic mode, or even changing from a high power to low power eyepiece or adding a Barlow upsets the balance. I can do these changes with impunity with a C14 and there is enough extra horsepower in the drive mechanism that I can get by.  I did not appreciate that for a small scope, balance changes are more significant and motors are much weaker.

I ran into the problem when I did a 2star alignment with an eyepiece, and then switched to a camera. I think the only solution for the iExos100 is to do the 2star alignment using the finder scope with the exact photographic optical train in place and the camera pre-focused.  I bought my iExos100 + 80mm F/6 refractor to have a portable rig for solar eclipses.  I worry that the metal cell of my solar filter will be enough weight to upset the balance.  The only solution I can think is to add a Velcro weight on my telescope tube when using the solar filter.

So I pulled the trigger on a Exos 2 pmc8 and cant wait to start taking consistent 5 minute subs. The only issue right now is my DSLR. Its pretty much useless in the summer here as the temps are well over 100 degrees everyday. Trying to image with it would not be good with he heat and a burning sensor. I need a cooled OSC, thats my next big purchase.


Re: RA Axis Issues #EXOS2

Justin Bailo <bailo.justin@...>
 

It looks like the screw above the dial may have played a huge part in this, also I am going to have to guess I had my weight balance way off. I had some cables mounted to the side of the telescope into a hub, and it seems this had changed the entire center of mass to slightly over the left side. I have been able to fix this after taking the entire scope down to the OTA.

Sorry not much time I will update with more later if it for sure fixed

I think it's unusual for a mount to just suddenly decide to start sticking.  I had a sticking problem, but it was right from the start - a ring gear ID tolerance problem that I was able to fix(!).  
 
But for this to come out of the blue is just odd. 

Do take a close look at Mike's cable suggestion.  Also remember that the DEC motor is offside and makes balancing fun.  Also, there's a chrome thumbscrew above the RA setting circles - check that it has not become tightened to the point where it drags on the mount's central axis.  And if that doesn't get you past it, I'd suggest you give Kent (ES Curtomer service) a call.
