This is an example of what we are seeing with high magnification on the iEXOS-100.  The "wobble" seen in in RA and times perfectly with the pulses heard from the control board.  When looking at the drive gear with the belt removed you can also see the gear stop and start in rhythm with the sound and it matches what is seen in the video.  Watching the video i count 16 cycles in 25 seconds.  I don't have anything but a webcam on the laptop so I am not sure I can get a video of the drive gear movement but I will try.

I have tried using the object tracking feature in SharpCap but it always fails in the RA calibration step and I wonder if it is because of this movement.

Ian

Welcome to the group!  There are lots of folks here that will help you get up and going.  Also you will find lots of information in the links that are on the web site.  Additionally just about every topic has been discussed and you might be able to find information through search of the forum.

The password should be PMC-Eight

Please give us the windows version and build you are using.  Also tell us what you are doing in the PC, Explorestars or ASCOM serial.

Suggest you start with explorestars.  

Regards
Wes

Windows 10 will not connect to my PMC-8 1856

Ian Morison
 

Hi Explore Scientific
   I have done exactly as your 'work around' states to connect to my new mount but it says that it cannot connect to the network - though it knows that it is there and accepts the password that I had to guess of pcm-1846.   Having done so, it would not connect any other networks as one would have expected.

Can anybody please help me?   I once designed computers and taught programming at University so I hope that I am not computer illiterate.

I would be really most grateful.

I wish to review it for my Astronomy Digest (www.ianmorison.com)  (note only a single 'r'') and include it in a fourth book for Cambridge University Press  (search Morison in Amazon) and am totally stumped.

Regards,

Ian Morison

Rule number 8 in the terms of service will be different for the PMC-Eight Application Subgroup and will now state:

The discussion SHALL NOT BE LIMITED TO describing the how and why of the setup, configuration, and any other requirements needed to properly get the third-party product to work effectively with the PMC-Eight system.

I will be amending the terms of service to include this statement in Rule number 8.

I will be adding every member of the PMC-Eight MAIN group to the new PMC-Eight Application Subgroup,
YOU WILL HAVE TO OPT-OUT OF THE SUBGROUP if you do not want to be a member. You can also set your email preferences under the Subscription menu item at the top of the left hand menu. 

Also, since this is a new Subgroup, you will have to copy your signature from the MAIN group settings to the new Subgroup settings. If you do not have a signature already set, please set one up, it helps everyone understand what equipment you have during your discussions.

Again, as always, I want to thank everyone for your support of Explore Scientific and the PMC-Eight system. We are moving forward and you can look forward to new and interesting products from us in the future.

Thank you, and Clear Skies!!

Of course, for general information the Internet and other forums remain a valuable source for information, but this subgroup will be where application-specific and relevant information will be able to be shared among us all for our common mount and controller hardware.

Look for an announcement soon from Jerry.

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

Wes Mcdonald
 

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.

Wes

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.
