Does it happen when a telescope and counterweights are on the mount?

Or when there's nothing on the mount?

And, by stutter, does it make a sound when it's doing it?

Hello, I recently purchased the IEXOS-100 and being new to computer mounts in general .
my issue is the RA motor just stutters at every speed but 8 or 9 on the explore stars app. Is there an easy fix for this or is the motor a Lemon?
using explorestars on an I pad and the app is fine.

Just to add, should I be updating the software for Explore Stars? The tablet that I use is dedicated to the PMC-Eight and is not connected to the Internet at all. I thought that this could have been an issue.

This is not as spectacular as a lot of what i'm seeing here but i'm pleased to have done it.  M81 and M82 through my Takumar 200mm lens stopped down to f/5.6.  Combination of 8-out-of-10 one minute exposures at 800 ISO.  Stacked and stretched in Deepskystacker and cropped to about 1/4 of the original.  My focus wasn't perfect and i probably over-processed but i like the look of it.

Thanks all! At least it happened right before I was getting ready to pack it in for the night.

I'll keep this in mind. It looks like a clear night tonight, so I'll be giving it another go :)

Hi Brian,

Wes is correct.  This is a feature/bug in the virtual joystick control used in the Windows version of ExploreStars.  The remedy whenever the mount is moving in a way that you don't want is to just press any of the UDLR buttons, it will stop immediately. I used this "bug" during development to drive the motors continuously at maximum rate for hours (not installed on the mount) to see how much the motors and circuit board would heat up. A good way to do stress testing.

I believe what you experienced was a stuck right arrow key press.  This happens on my android tablet and is caused by your finger simultaneously touching the right arrow and the edge of the screen display.  For some reason this locks the right arrow.  The arrows are not locking normally and are active only while your finger is on them.  So anytime you remove your finger from an arrow and the mount does not stop slewing something is wrong.

The cure is to tap the button again, any of the arrows.

I have not experienced this with the iPad, and have not heard of it occurring with one.  But it might have.  

This little odd behavior has been occasionally reported in the forum but it would be very hard to find it in the messages.  

Sorry it ruined your nice evening.  But next time if the mount does not stop moving when you take away your finger from an arrow key just tap one again and all will be well.

If you are not using android please tell us.

Odd software behavior of Explore Store App #ExploreStars

Bryan
 

Hi All,

I was observing M3 last night after two star tracking and it was superb. It was close to midnight and it was right overhead. The scope was tracking the cluster just fine and I was really enjoying the show. I noticed it wasn't quite centered, so I adjusted to the right on the control pad - using a touchscreen device - selecting "3" and the scope moved without stopping until it reached the horizon. There wasn't much I could do to stop it. Even though it was pointing at the horizon, it was indicating that is was still tracking M3.

Does anyone have any idea why this could have happened? While it was slewing, I checked the wifi connection and it was still connected to the PCM Eight. This is a Windows 10 tablet using a version of Explore Stars that 's about a year old. Any thoughts?

Thank you Jerry for your dedication and the sacrifice of your free time in supporting this forum. It must be difficult considering there will always be new comers to the astronomy hobby and therefore many of the same questions over and over which I am sure is a challenge to moderate.

 

Thank you again,

Subject: [Special] [ESPMC-Eight] Further Explanation About A Recently Locked Thread #ExploreScientific

 

Dear Members,

The recent thread entitled “Camera shutter control w/ iEXOS 100” asked a question about whether the PMC-Eight iEXOS 100 mount system could be used to control a DSLR in taking pictures. There were several responses suggesting that an intervalometer is typically used to perform the desired functions. We do get suggestions asking why we don’t provide a feature like company X, or company Y, and suggesting that we should add this specific feature which was the context of this question. Rest assured we evaluate every customer suggestion and make decisions about whether to include it in our future products, we just won’t always say that about a specific suggestion. To be clear, the PMC-Eight is a “precision motion controller” that is dedicated to controlling the mount and is just one component of an overall mount goto navigation system.

 

Since the forum was created to support our customers and prospective customers in answering their questions about the PMC-Eight control system, I felt that this particular thread had fully answered the question about how best to perform DSLR shutter control. I decided to lock the thread because it was not PMC-Eight related at that point, and suggest more information could be obtained by going to another DSLR related forum, i.e. CloudyNights.

 

For those new to the forum, here is a little history. Even though I am the VP Engineering for Explore Scientific, I started this forum almost 3 years ago and managed it as it grew from a handful of members to almost 400 members today. New members do not know the history of how I personally support our PMC-Eight customers 7 days a week, day or night (sometimes) to maximize their success using our products. We are a small company so every one of our employees wear multiple hats including me.  In the past year I have appointed 4 moderators to the forum and very much appreciate them taking the load off of me to answer the most common questions new members have. I still try to do my part to answer questions on the forum and have overall authority as to how it is moderated.

 

Some of my customer support is done off-hours and are overtime hours I spend outside my normal work activities working on improving existing products and on new product development. I am available to customers most anytime, and I will break off what I am doing during the day to handle a problem that Kent typically brings to my attention.  I enjoy supporting our customers and have made a lot of friends over the years.

 

So I hope this clarifies why I locked the DSLR thread, and my continued support of our customers.

 

Thanks for being a member of the PMC-Eight Forum and I look forward to helping you become successful in your endeavors.

The cameras all have built-in interval timers. You can only do a sequence with shutter speeds to 30 seconds. You can't automate a bulb sequence with those; either built-in, or accessory.

I'll check out those software applications.

 Thanks. Haven't had to look at accessory interval timers for many years. I read about the Vello one linked earlier and didn't think it did, but may have misread. Will look into some of these for Nikon and see what's available.

Thanks. I'll have to look into remotes like that again. In the past, you weren't able to sequence Bulb exposures even with an external interval timer.

I use Astrophotography Tool on Windows and I'm trying to learn Sequence Generator Pro.  I have tried NINA...not successfully

You can do longer than 30 second exposures with an intervalometer like a Shutter Boss.   https://www.bhphotovideo.com/c/product/840096-REG/Vello_rc_c1ii_Shutterboss_Version_II_Timer.html

Robert,

You can get a cheap intervalometer if your camera has the suitable port. I have one that cost about $10 and it works well. D800  Z6

If you want to get into full control with a computer, newer Nikons and Canons are well supported in most astroimaging software. Something like BackyardNikon or NINA on a PC or laptop should suit your needs. I use NINA with my Canon and it is great. It's a very powerful sequencing software that also happens to be free and open-sourced. It is well supported by a very active development group.

Other models aren't well supported but people have found work-arounds.

I'm considering buying an iExos-100 PMC Eight setup. Have done a forum search and didn't find an answer.

Products from iOptron and Sky Watcher include the ability to manage the shutter of a DSLR for longer (>30 sec) exposures. The ES product does not.

What are users of the iExos-100 doing to control the shutter automatically for Bulb exposures?

Thank you.
