newbie alert

Think it's moved on from an idea... You obviously don't follow what's happening...

I've no idea how eqmod works, but ascom tends to stick the boot in every now and then.. I'd bring up the ascom diagnosis, and just make sure the mount is connected in ascom.. then connect as usual in Nina... Best thing is you can do this during the day and not have to wait for nightfall

Software has a dendancy to decide not to work, or other softwares throwing things out..IE like eqmod conflicting with other softwares, and ascom creating havoc

Did you re do the pa? If you had to adjust then that should tell how far out it was..

Take it your using eqmod? Was it unparked in both softwares, not sure which takes priority...can you hear the hum from the steppers? Like it is tracking? Certainly could be pa, certainly drifting in that direction

The locking bolts that bolt down from the top?

Doubt it would change any of the pec( period error correction) With any of the synta mounts those locking nuts are all over tightened , it has the effect of sandwiching up the ring bearing and locking up the axis... Best to have it loose but not to a point that you have play ( up/down) in the axis..once tightened I'd go as far to say the grubscrews need equal tension You can go further and adjust the height of the worm/ ring gear as from factory that's also usually wrong.. but that needs teflon washers and the whole mount dismantled, so while you're doing that you may aswell change the bearings in the worm and it's tension as again that's usually again wrong You can get to fettle and adjust most things but just know that you void your warranty as soon as you start taking it apart.. just depends on how far you want to go

Is it parked? Sometime you need to unpark

I'd recommend as above, and also run a dark library.. PhD should prompt you to do it.. Put the camera on loop and adjust the focus, exposure and gain.. put the slider on the bottom to the right, this is for on-screen viewing... Then run it through the calibration process

Jupiter certainly has enough mass but don't think it has any influence on earth spin... A quick search says there maybe a influence on earths climate from Jupiter and Venus, can't find anything on this affecting it's rotation.. earth has a natural wobble) chandler's effect

I was on the understanding that earth would slow down on its rotation speed..

The 183 has a bigger sensor and smaller pixels so that's where the MP come from... I'd look at bit depth differences to compare

Ok reading further on sounds like you could have a physically moving flat, literally... So the dust that wasn't removed can you see it in the individual light frames, or does it get lighter or darker once offset

If you took the time to read my short message I mentioned a few times that it wasn't a directly about cost.. and the reasons why about Onstep.. it's not my fault you chose either not to read or absorb it or to skirt around it like it wasn't there..

All that to agree on the maxon/Sitech setup🤪🤔🙄

Try about a third of the histogram or adu range If you use Apt or Nina both have a flats tab

Thanks Tony for your reply, no it's not directly cost related answer but like you said yourself steppers and servos have strengths and weaknesses, I could ask you the same thou, are you implying that the nema17 is as equal in quality as the moxan motors? Why wasn't NEMA 17 used on the rover or helicopter on mars? Do you believe that Onstep is either on par or superior to Sitech?.. if so why can't absolute encoders be used with Onstep at this present time, maybe sometime in the future At the moment for Lucus the system that he's using with the mesu has proven to be pretty failsafe... I hope that continues to be the case for him These are the reasons, not a direct cost related answer but as you know, quality components cost that little bit more than cheaper mass produced items The friction driven trident is now being used with NEMA 17 and Onstep, which wasn't the original spec, do you think that was because of anything other than cost.. mark continues to sell encoders for these mounts even thou they can't be used at this present time

Onstep is more the board components... But a few people have gone a stage further and designed and made their own mounts, I've seen friction drives and now a few 3d prints...Inc this one which is the startracker https://onstep.groups.io/g/main/topic/91624985

Vlaiv, are you familiar with Onstep? A few guys on there have 3d print designs, one of which lately done a startracker with a budget of 100 dollers

Does that mean that it doesn't work? I've not read any negatives from mesu owners.. only ever positives... All I was trying to say was in my opinion downgrading the motor's, changing the system to more open source is a step in the wrong direction ..

Isn't that what I said?

The XLT image circle is too small for the APS-C sensor

Thanks, but no they're with the XLT version and 6.3 reducer

The sitech system has been foolproof for the mesu mounts, armed with the maxon steppers and encoders ,as mesu owners say they just work.. no need to dabble or fettle Maxon produce really good motors, so good that they're used on the Rover and helicopter on the Mars mission.. I see using NEMA 17 steppers on a fail-safe system as a backward step, yes they can be used on open source systems but some of those systems don't support using encoders as a example.. not sure on the moxan motors cost wise but NEMA 17 are really cheap (£20 ish for 2) and can be purchased anywhere from steppersonline , Amazon and eBay.. don't think you can buy a moxan from those sources ... The mesu is a quality product, made and setup with quality products and software, can't see cheaper products working on the same level of quality.. The trident did start off spec wise using moxan motors, sitech encoders etc, now the spec has changed to using NEMA 17,Onstep software etc
