Re: Latitude adjustment problems/difficulties?
Wes Mcdonald
I put an acorn nut on the end of the screw that raises the thing. That seemed to reduce friction quite a bit, but it constrains how low the altitude can be set to. I have mine at 33 degrees and it is fine.
It is a pain, I have to admit. I leave mine set between runs, and have the site marked so that the tripod can go back in the exact same place, so additionally adjustment is minimal for each PA.

Re: ipad doesn't seem to control the pmc-8

Wes Mcdonald
No. It works fine with iPadOS 16.4 in my 6th gen.
Be sure to load firmware .02 or .03. If your iPad is having issues make sure the pmc8 is in udp mode if it is an iexos. Otherwise I have no clue Wes -- Wes, Southport NC EXos2-GT PMC-8, iExos 100 ES ED 127, 10" LX200GPS+wedge, Astro-Tech 8" Newt, ETX-90, 60mm no-name guide scope ~ 260mm FL Polemaster, Orion ST-80 and SAG, ZWO 290MM, D5300 astro modified Nina, Bootcamped Mac Mini control computer, RDP to iMAC 110 amp hour lead acid deep discharge battery for field power Electrical Engineer, Retired

Wes,
So do you think the latest update caused the problem with the iPad? I guess I should have tested before the update. Phil

Re: motor noise and irregular rotation

Found this online.
Im seeing the same wobbly motor rotation on mine. https://stargazerslounge.com/topic/357104-iexos-100-stepper-motor-nonlinearity/ Pointing out to be the chip controlling the motor or the motor itself. Anyone know the company does the servicing for these mounts? Thanks!

Re: Latitude adjustment problems/difficulties?
Gokhan, Not sure what you could do about that - any solution would be constrained a bit by the casting material and mount base itself. But... if bending is a problem, that just says (to me, anyway) that a) the factory handscrew material was a bit soft, b) there was a lot of friction, and c) maybe a bit of over-tightening? The thread below deals with knob replacement, some of us have done that. Have a read. This is a pretty straightforward change - just needs a couple of Metric threaded knobs. Here in the sunny south of Canada, I had to order these online rather than pick them up a a hardware store, so you may need to hunt a bit as well, but not difficult. I did round the ends a bit (that's what Ken't "bald head" refers to), to reduce friction and scraping where they push on the mount. No biggie - slip a nut onto the threads, file the end a bit, remove the nut (cleans up any burrs on the threads). Done. I also put a dab of Superlube on my Alt-Az threads. I do have to remind myself not to overtighten, but other than that, this works well for me. - Bob

Latitude adjustment problems/difficulties?
GKHN SRL
Hey all, first time posting here,
I've had the ES exos 2 pmc8 for a couple years now and i'm rly impressed of what it can do, even with heavy load and high'ish focal lengths but I'm having a hard time with the Polar Alignment, with the Latitude adjustment be more specific . The 2-Knob-system feels very unreliable in my case, even made custom ones since the original ones bent, so I was thinking about upgrading it somehow. Has anyone done anything like that? I'd appreciate any ideas rly, I feel like I'm breaking my fingers adjusting the knobs lol. I've seen the wedge upgrade for the NEQ6 but I was hoping for a simpler solution ( https://www.teleskop-express.de/shop/product_info.php/language/en/info/p7490_Vimech-Wedge-for-Skywatcher-NEQ6-and-Orion-Atlas---more-stability.html ) Greetings from germany Gokhan

motor noise and irregular rotation
Leandro Gonzalez
Opening a new thread as requested.
When selecting tracking ON on the Asiair mount panel the motor vibrates a lot and spins irregularly. It continuously starts and stops. Green light on the mount blinks and doesn't stay on. Does the unit need to be sent over to be serviced? Feel free to move this thread to whatever subgroup or such it shall belong to. Just need to know how to proceed into fixing this. Thanks

Re: Tracking and guiding issues on asiar pro

I just opened the little plastic cover on the RA side that has the motor and the worm wheel.
Looks like the motor spins irregularly and with a lot of vibration. Tried it with no guiding. Just mount tracking. Green lights blinks on and off doesn't stay on. Another lost ight. Is there a service dept where the unit can be sent to be checked?

Re: Tracking and guiding issues on asiar pro

Just wanted to hop in quickly, before you shift the conversations to the Applications sub-group.
I had a similar issue, and found that telling the asiair to flip the meridian would often help (as I think I was always on the opposite side of the meridian to what it was calibrated for when I had the issue). Have you tried this? It's very easy. Just select the "i" with the circle around it in the auto guide screen (shown above). Then flip the meridian by selecting the option. It should also make the auto guide re-calibrate once you start again. -- Mounts: iExos-100 + ST1 Tripod + Az Adj Scopes: WO Zenithstar 71 + 0.8x Flattener/Reducer, Celestron 5SE, Starfield 60mm guidescope Cameras: Canon 60D (non-astro) main cam, ZWO ASI120MM Mini guide Software/Computer: ASIair Pro

My iPad is a 5th gen running 14.6. So I don’t think it uses an M1 chip. I’m not an iPad person but it looked like a good way to control the mount considering the IP address issues with the pc

Re: Tracking and guiding issues on asiar pro
Leandro Gonzalez
Hi all, Vlad, sorry to hear you are having problems too. Last night i did the polar alignment with the asiair and got to be 8” off. The night i had terrible trailing at 30 secs and up i was at 30” off. Not sure if that was what did it but last night i was able to track and guide decently at 60-120 secs. Also, the night i had the intermittent issues with tracking and guiding was under full moon and it was very difficult to get anything. I think its important to rule out that the guiding and the PA is not throwing of tracking. After pa i think its important to get a decent 30-60 secs exposures. My pmc green light keeps blinking while using the asiar. Is that relevant? Thanks all!

Re: Tracking and guiding issues on asiar pro

Hi Vladimir, looking at your guiding screen you are not in focus plus your exposure is too low, should be about 2 seconds and your gain seems high, you have not specified which guide camera you are using? I suggest if you still have the same problem after adjusting you go on to the ASIAIR Pro (AAP) Facebook page and ask for help but get your guide settings right, there's lots of helpful support like on this forum but this seems to be an AAP issue to me.

Re: Tracking and guiding issues on asiar pro
Hi,
toggle quoted messageShow quoted text
I have very same problem with autoguiding on ASIAIR Pro, mount iEXOS100 pmc8 - starts ok then very quickly the graph curves fall apart. Also, when I let it just track (no guiding), after few seconds the mount just “lets go”, doesn’t seem to track anymore. When I am using just mount itself (no ASIAIR) controlled by iPad via ExploreStars app, tracking works ok, andI can do 30” expo with my 154/600mm TS Photon newtonian scope without trailing - but I aim for autoguiding. Please help, Thanks a lot, Vlado   Ing.arch.Vladimír Schmidt,AA www.zvarchitects.sk
