Hi Kent, all,

I'm also using Raspberry Pi 4 4gb with EKOS + Kstars with my  EXOS-2.
Doing all orchestration with it from polar alignment, plate solving, guiding and picture acquisition plan.
By now all is working really great.

Kind regards
Bogdan

Hi everyone!
 I just purchased the Explorer Scientific EXOS2. I am just waiting on a dovetail to mount my scope. I am new to astronomy and astrophotography and have numerous questions to ask. First I would like to know if you can hookup the PMC8 to my laptop wirelessly without wifi? I'm also having a hard time finding a DB9 cable locally. The other question I have is concerning Explorer Stars program. I have followed all the download instructions, but when I open the program, I t says "data files missing". What am I doing wrong? Thanks in advance!

This is from Groups .io  HaHa.  When you hit subscriptions for that group divert your eyes to the right and read all the stuff there in the panel.  It includes where you set your signature.

You have to set your signature in each  subgroup you subscribe to.  Bummer.

How Do I Set Up A Signature For My Account?

To set a signature for your account, go to the Subscription page for your group (it's the 'Subscription' tab in the left hand sidebar when viewing your group). On the subscription page, look for the 'Use Signature For Web Posting' checkbox and check that. Then you will be able to add a signature. Once complete, click the Save button at the bottom of the page to save your changes.

All,

I was doing some mount RA & DEC axis testing on my EXOS-2 GT and since seeing and transparency were around 3/5, there was a full moon out and in general with Houston's Bortle ~9 skies, I wasn't expecting much, but I ended up a bit surprised on how well it turned out.  I used the Western Veil nebula as a test target and grabbed about 3.5hrs of total exposure (180sec individual lights) over two nights on my unmodified Canon RP and using the Optolong L-eNhance filter, where the average guiding error was ~1 arc-second.

I wasn't planing on doing any AP work with full moon and average seeing, so I guess the moral of the story is that if you don't try, you won't know how good or bad something will turn out.

Regards,

Vince

locked Do you need/want/use the additional safety of the communications watchdog in the PMC-Eight system? #poll-notice #poll

Jerry Hubbell - Explore Scientific VP Engineering
 

The PMC-Eight system delivered with the G11 and EXOS 2 includes a safety feature from the factory that stops the mount motion when the communications loop is broken between the host program (ExploreStars, or ASCOM driver) and the PMC-Eight controller. Do you need, want, or use this feature. It is currently not included on the iEXOS 100 mount from the factory.

Thanks

HI Harry,

The original 9TX version of the firmware delivered only applies to the G11 and EXOS2 (Model 2A circuit assembly - "big board") have the communications watchdog enabled. The 9TXa version has the communications watchdog disabled. When we released the iEXOS 100 I only offered the firmware with the communications watchdog disabled, as most people who owned the model 2A G11/EXOS2 weighed in on it and did not like it. 

It is important to note that the communications watchdog was designed to be an additional safety feature for the PMC-Eight system when using ExploreStars in case the tablet was shutdown, or if the user walked away from the mount with their tablet. When using ExploreStars, the system will pick right back up where it left off when reestablishing communications - it will slew to the current position of the target object even if the mount has been stopped for a while. Everyone needs to understand that this feature was in the context of the primary use-case for ExploreStars was for visual use at the mount, not for astrophotography.

The system will stop also when using the PMC-Eight ASCOM driver if the computer driving the mount goes into "screen saver" mode, or if it is disconnected (serial, or wifi). Most people using a computer to control the mount for astrophotography have their systems set to NOT sleep and any astrophotography session is an active process which maintains communication with the mount to query and obtain real-time position data with the mount via ASCOM. In this case, the communications watchdog being enabled is not an issue typically, and has not been an issue for those using it this way.

So bottom line, since we deliver the iEXOS 100 with the communications watchdog disabled, there has been no request to provide a version with it enabled, as everyone just expects it to keep tracking regardless. It is up to the user to decide how they want to use their mount. The additional detail here is that, as we taut in our literature, the system uses a safe stepper motor drive system that even if the equipment runs into an obstacle there will be no damage to the mount or equipment, it is still a safe system.

I think I will create a poll to see if anyone wants to have the additional safety of the communications watchdog for the iEXOS 100 mount and our mounts going forward.

Thanks

Re: New owner #EXOS2

Wes Mcdonald
 

Welcome aboard TJH!

So we sort of like to know a bit about you, like a name.  If you add a signature section to your profile in groups.io that would help, as we would know what gear you have going forward.

I think you will find the folks here helpful and kind.  Don’t hesitate to ask questions as they come up.  

The search tool will help you research questions.  Most pmc8 questions you will have are not unique to you and will have been covered.  You might just be able to find the answer.  But if you can’t, please ask.  

The mount you bought can do an amazingly good job.  It just requires some patience and effort from you as you begin your journey in this great hobby.

Wes

Hello all,

    I have ave searched for a new owner topic and could not find one so my apologies if this is a duplicate. After much research and thought I bought my first mount exos2gt pmc-8 new from explorer scientific. I am excited to try this mount I really like the load capacity of the mount to give me some growing room. I have been using a Celestron Newtonian and alt/az mount to view. I love the idea of wireless connection and being able to use Stellarium for GoTo, I will do unguided at first with an Olympus em1mkii and lenses up to 500mm until I can purchase a guide camera/scope and ultimately a camera for polar alignment/plate solving.

Question about the communications watchdog disabled "a" version of the firmware #ExploreScientific #FIRMWARE

Harry
 

This is a question for Jerry regarding “B” firmware.

Jerry, I see people changing to the B firmware version to keep their mounts tracking if somehow ExploreStars were to enter a sleep mode. Example,  this conversation in using ASIair.  Last time I upgraded my iExos 100 firmware, I believe there is no B version. That B only applies to other PMC 8 mounts. Is this correct, and therefore the B version “fix” is not necessary for the 100? 
Thank you ,

The iExos is listed in the drop down menu in the Asiair, along with the Exos2-PMC8 and the he G11. I’m assuming it will work fine. 


Wes, most nights I’m imaging in about 20 minutes. Everything fires up and works quickly and I can sit inside and control everything from a tablet. I was able to get Ascom, POTH, etc., set up when I first got the mount but haven’t bothered with any of that since. There is a limitation: only ZWO cameras and DSLRs. If you want to use other stuff, Stellarmate  works well. Same idea but more fiddling around and slightly less reliable. But Stellarmate also connects Exos with SkySafari and that is really cool when doing visual. Point your phone to a part of the sky and it just skews there with one touch.

Hi James, I do not own one either, but I can confirm  that EXOS 100 is in the list of supported mounts of the ASIAIR Pro, so is the EXOS 2 GT  PMC-8. Since the 100 does not use a FTDI cable, it might be easier to connect I would say as you do not need any programming of cable.

The iexos is pretty much identical firmware to the exos2. Should be fine.  Maybe there is an asiair person out there with an iexos to weigh in

You asiair people are starting to make me think maybe that is how to go!  Cool
