Re: Possible defective unit - SOLVED! #iEXOS-100

Guys

The movement of the steppers is not perceivable in images.  The steps are way to small to be discerned by your camera.  Just so you know when you are actively guiding, where the motor rate is altered at a two or one second rate (one of your many guiding parameters) the mount maintains pointing to 1 arc second or so.   This is smaller than your imaging pixel so that is how you can integrate for 2-5 minutes and not have any smeared images.

If you are imaging with explorestars, not recommended, if you are seeing movement it is because the thing is in P mode.   In that mode the mount only updates it’s position 5 times per second.  It is literally still for most of the time between pulses.  Objects move in camera-discernible amounts in 200ms.  You must image in T mode which is tracking.  In T mode the mount runs at sidereal rate in RA and not at all in DEC.  there is essentially no interval between stepper shaft rotations (ok there is , it is 23micro seconds).  This is 43,000 times per second.  Your mount has inertia and believe me, those tiny nudges 42000 times per second are silky smooth by the time the mount filters them.   

If you are not guiding then your explorestars (it any other control app) basically needs you to have very good polar alignment.  This is where the most error in your images is going to come from with out guiding if you are in T mode.  If you insist on not guiding then you are going to have to learn how to get superb polar alignment.  And then operate explorestars in T mode .  

For bright solar system objects any small difference between sidereal rate and the object won’t mess up your short exposures .   But with poor polar alignment the objects will slowly march across the camera field of view with slight minor rotation between images.  You just have to live with it and post process it out.

Hope this helps your understanding of this mount.  Believe me, if stepper motors were somehow inferior to servos virtually every manufacturer of mounts would not be using them in new designs.  As far as I can see they are superior in almost every way.

Thanks James, the pulses in the movements of the image when doing lunar planetary imaging at magnification is exactly what I am seeing also. 

Is there any way this can be minimized without having to remove it with an additional step in post-processing?

Unlike a constant spin of a servo motor, the stepper motors move in pulses, it is why there is no need for encoders, since the software knows how far the mount moves with each pulse.  At low f ratio you won't see it, but when working at f10-f30 for planetary they are easily seen.  Fortunately stacking software nulls them out and doesn't affect the image at all.

This is not great imagery but it's fun.  Two images of the area around Neptune captured 6 days apart then aligned and made into a gif so you can see the planet moving against the background stars. Each image is eight 60 second subs at ISO 400 through a Takumar 200mm lens at f/4 on a canon t3i.  Neptune in fairly bright at mag 8 so capturing it is fairly easy but finding it in the images was tough.  I wasn't completely sure until I had the second image process and it had clearly moved.

For what it is worth sound even occurs with the PMC-8 G-11 version.
It started with the v14 firmware update that increased the torque of the stepper motors.  Here is a YouTube video that I recorded in August of last year.

You use the same technique that I use to align my scope.  SharpCap makes it super easy.  One thing I did to make sure I put my tripod in the exact same location of my front yard was to put three PVC tubes vertically into my yard at the location of my tripod legs.  I then added some 3D printed parts to cap the PVC pipes and locate the tripod legs exactly.  Now my setup is even quicker.  The details are described here:  https://www.thingiverse.com/thing:4176066   The next best thing would be to have a pier in your yard but that's hard to mow over.   lol.

It is easiest to do this with a digital level (or a smartphone), a small dovetail bart and a compass with a ring for adjusting magnetic deviation (or a smartphone)

Here are images of the steps.


Step 1: Set mount in Park position and level mount base any way you can in both North/south and east/west.
Step 2: Set your dial indicator to zero
Step 3: Set mount to your latitude with digital level or smart phone
Step 4: Level counterweight bar
Step 5: Level the dovetail bar
Step 6: Verify compass heading taking into account "Magnetic Deviation" (Use a compass or smartphone) with an adjustable ring to help with this.
Step 7: Verify resulting dial indication is very close to your latitude

Something similar should work in the Southern Hemisphere.

Re: Recommended Polar Finder that will work with IEXOS-100 PMC-eight

Wade Prunty
 

Let me preface this by saying I am totally not attempting to be condescending here. I had a real hard time with polar alignment on my Celestron CGX when I first got into this, so much so that it almost made walk away from it all.

I think we're blowing this way out of proportion. I get really good polar alignment, goto results and guiding with my iEXOS-100, and this is coming from someone who has never used a polar scope. I start off by eyeballing my mount with Polaris, I just get it as centered as possible over the top of my mount. I then use the bubble level and adjust the tripod legs to make sure the mount is level. Then I make sure the mount head is set to my altitude. With all of that done I then use either the ASIAIR Pro, or something like it (SharpCap), to finely adjust the alt/az knobs to complete the polar alignment. I am polar aligned in under 5 minutes, every night. If you are imaging you should, at the least, be able to connect your camera to a laptop and use SharpCap.

Also, if you don't trust the mount's bubble level, you can adjust your tray on the tripod to be extremely inline for leveling, so that you have somewhere else to use a level on the mount.

Re: Belt tracking issue after adjusting EXOS2 RA drive train.

 

On Thu, Sep 17, 2020 at 10:54 AM, John wrote:
Can I assume that the current tracking of the belt indicates the axles are diverging from each other and that I need to bring the tips closed together?
John,
 
That's pretty much what I worked through on on mine, although in my case it was the small pulley's keeper that it persisted in going towards.   
 
One thing to add, though, is that there appears to be more than one type of belt movement, one significant, and one not.  Mentioning this because you didn't say how the pulley was being driven when you ended up where you are.
 
Case #1: Persistent misalignment, where the belt moves against (in my case, the keeper) quickly and consistently, just with hand turning, and it rubs where it stops.   This produced a very prominent 133s wave on an unguided PHD2 log, and sometimes even a prominent 13s wave (from individual pulley teeth).  These short-period waves did affect my guiding (ie: more error to compensate for), and quieting them down made quite a difference for me.
 
Case #2: Behavior #1 is not present, BUT... If the axis is driven under power in one direction, the belt drifts slowly to one side, and if driven in the other direction under power, it drifts back.  I have no explanation as to why this happens during a directional change, but the lateral drift of the belt does not appear to be forceful, and it doesn't affect my guiding.  I harbor a suspicion that the belt movement might make a difference until it settles, but whatever effect that is, is tiny.
 
Hope this helps...
 
- Bob
