Re: Files missing

Typically when files are missing it's because you didn't load the database in the correct directory.   Use the configuration manager to put your files into an SD card and u will be fine.

Files missing

Alberto .
 

Hi,

I tried to use the app explore stars with the Explore Scientific iEXOS-100 PMC-Eight.

I did everything mentioned in the web, but the app doesn't work. It says 'files missing'.

Any help is appreciated.

Cheers.

Just because you can never have too much Great Orion Nebula, here's another!

This was using the live stack in SharpCap (that qualifies as EAA in my book).
A stack of 36 11s subs, so 6.6 minutes total. No darks, bias, or flats.

Scope: AT80, straight
Camera: ASI294MCPro at -5c
Mount: EXOS2 PMC8

Amazingly, I think at least 4 satellites went through the frame during the exposure on 12/30/2019... for a minute I thought I may have been watching a meteor shower, but they just kept on going.

Tracking noises - pulses or continuous tracking?

Pavel
 

Hi,

I was a bit surprised/scared by the "breathing sounds" of my new
iEXOS-100 mount, but according to a video of the moon taken at a great
magnification (see https://wanthalf.saga.cz/media/Moon_tracking.mp4) the
sounds seem to correspond to tracking movements of the mount - it seems
to happen in pulses, "hunting" behind the object. What makes me puzzled
is the fact, that the first iEXOS-100 mount I have hold in my hands did
a *continuous* tracking sound, not in short pulses like this one.

So, I just wonder, what is the standard tracking behaviour of the mount?
I suppose that a continuous slow movement would be more suitable for
astrophotography than such "jumps".(*) Can two mounts behave
differently? Or is there another factor I have not been thinking of?

Best regards,
Pavel

*) Of course, I am well aware of the fact that this mount is not
supposed to support magnifications/focal lengths like this one.

Yes, the support is there, in the INDI driver. Bit the problem is
obviously on the side of the mount, so there is probably no help. I
tested the communication manually and it just does not seem to respond
well. INDI cannot do much about that.

Anyway, I have already asked the audience in the INDI forum, but it does
not seem there are many people following. Nevertheless, I also consider
the wired connection more reliable, so I am quite happy this way. The
only problem is the difficult way to switch to ExploreStars in case
something goes wrong. And there are other things that make me worry -
never know if something is just my mistake or a real problem...

Regards,
Pavel

Pavel,
 
I did a quick search on forum posts and see that wireless PMC8
connection for INDI has been worked on, as well as wired, although
whether that covers both flavors of PMC8 wifi, I wouldn't know.  In any
case, wired would be the more reliable connection.
 
If you do want to get your mount (an iEXOS-100?) working with INDI and
wifi, rather than wired, I'd suggest you open a new post, specifically
asking for help on that.

Re: New to Guiding

Hi,

I tried to establish a wireless connection with INDI drivers without any
success, and it looks like it is a problem of the mount. It probably
receives the commands and works, but the problem is responding. For UDP
control it probably never sends any response at all, and for TCP it is
responding with great delay (if at all) and confuses the INDI driver.
So, wired control seems the only working way.

Best regards,
Pavel

I'm guessing download the PMC Configuration Manager as well? Is it
pretty intuitive?
Thanks again for all the help. I'll probably get the cable and start
there with CdC and get that up and running first.
BTW anybody use the ASIAir Pro...all wireless and self contained?
CS,
Jay

PS...a bit cloudy, bad seeing and transparency tonite..not so good for
the meteor shower.

Re: New to Guiding

 

Jay,
 
You're welcome :-)
 
The Configuration Mgr is indeed useful.  
 
Remember, the cable needs to be an FTDI cable, don't forget to install the drivers for it.  The search tool here will turn up some reccos for you.  The drivers create a virtual COM port for the PMC8 driver to connect to.
 
Do a search here and you will find a few folks using ASIair, or Stellarmate or INDI (all related).  I believe the INDI drivers (linux, I  don't use it yet, but some day...), came together about a year ago, so support should just flow through to those products.  Wireless in the PHD2 control loop is probably not a good idea, but lots of folks doing a remote session into their scope computer running that control loop.  I use TightVNC from my (warm, inside) laptop over the house wifi, into my laptop outside.  More than one way to do it.  :-)

Bob,

Many thanks sir! This will get me pointed in the right direction for sure. I'll try also to download and use CdC. Where can I find POTH and could anyone recommend a good powered usb hub..not sure how many ports to look for.
CS,
Jay
PS..one last thing, can I get this up and running in the house (of course guiding won't work) to work out connections etc??

Yep, lots of posts here on guiding, but if you're just getting oriented the connections between the dots might not be apparent.
 
The PMC8's ST4 port is best ignored, in favor of What's called ASCOM pulse guiding.  You should use wired connections, for their reliability.  Unless you have a scope computer (laptop?) with a lot of USB ports free, you will probably want to connect mount, cameras, etc. to a POWERED usb hub, not unpowered (reliability again). 
 
I can't speak to Stellarium, as I don't use it (CdC here).  

My physical USB connections for guiding, FWIW, look like this:
Guide camera                                                    -> USB Hub
PMC8 (via FTDI serial-to-USB cable + driver)  -> USB Hub
USB Hub      -> Laptop
 
On the laptop (and leaving out a bunch of stuff not relevant to your question): 
ASCOM POTH w/PMC8 driver (the ASCOM server/hub) is running and connected to the PMC8
PHD2 knows how to connect to POTH for the mount, as part of its initial setup/config.
PHD2 knows how to connect to the guide camera (remember, it's a USB device), as part of its initial setup/config.
When you start PHD2 for guiding, you tell it to connect to POTH and the guide camera, using the config set up earlier.

What do you need plate solver in? What is your image acquisition program? The various plate solvers are : PS2, ASPS, Ansvr local or remote, ASTAP, Astrotortilla with or without Nebulosity, N.I. N.A. <<<NINA is a good one because it is free and you can download ASTAP and the database from hnsky.org<<<ALL FREE. There are others. My unusual camera drove me to investigate plate solvers and then programs that are set up for image acquiring with supported cameras

New to Guiding

Jay Stanley
 

Greetings and happy new year,
Sorry if this is redundant, I did do some searching thru the messages and still don't understand. I'm looking into setting up guiding on my EXEXOS2 PMC Mount and need to know what and how to hook up a guide camers. The PMC has an ST4 port, do I use that and how does that talk to the computer? VIa Wifi? Also wanted to use PHD software or others. I've seen using serial connections etc. Not sure how to do that and you have to remember your talking to an ID10T user :)
I had the scope up and running using Stellarium and Stellarium scope but that's been a while back, I can figure it out again but others seem to prefer CdC. I'd appreciate any help. Weather's been awful in OKC area and most of my AP has been solar or lunar so no guiding needed.
Best to all,
Jay


Re: EXOS2 PMC-Eight #EXOS2

 

Saif,
 
Should be ok for all four reqts you list, although it depends on what you mean by expandable.  Can the mount carry a variety of loads?  Yes.  I'm sort of midrange (102/621mm, about 13.5lbs all-in), and there are folks here with both heavier and lighter, longer and shorter FL's.  Just don't go crazy and try to park a monster on it.  If you mean expandable in the software sense, the PMC8 controller is control-program agnostic, and is not tied to any one. 
 
I can see Polaris, so for me a PA is easy (via Sharpcap), but there are folks here who can't see it and have found alternatives.  If they don't step in on this thread, just do a post like "How do I do a PA when I can't see Polaris?", and folks will likely show up with advice.
 
If you intend to do astrophotography, then think about plate solving.  No need for 2/3-star alignments and a blocked horizon no longer matters.  I do a PA and slew to where Cartes du Ciel thinks my target is.  It will be close, but not necessarily in-frame.  Then I tell Astrotortilla (integrated with BackYard Nikon) to center-and-sync.  It requests a picture, plate solves the picture, does a small slew to correct the mount's position, rinse and repeat a couple of times, and after a couple of minutes, my target is centered and my mount sync'd.  It's magic, and this is just my software stack - there are others that can do this as well.   
 
Your 75-80mm tripod footprint is touch-and-go.  Assuming that the tripod legs are collapsed down for AP, that's awfully close to their spacing (which probably varies a bit between mounts).  Basically the tripod legs are hinged and swing up-and-out until they bump into a stop on the tripod head.  Tightening the threaded rod that ties the mount head and eyepiece holder together creates an outward push against the legs, and holds them tight against that stop.  
 
So...for your small EXOS2 tripod footprint, I would think your options are:
#1- Try it and see. It might work...
#2- Come up with a platform extension for the porch.  You shouldn't need much overhang and this would have the advantage that you could put a safety lip on the edge so the legs can't slide off.
#3- Shim the stops on the tripod head, so the legs hit the stops sooner and the footprint is reduced by the little bit that you you need, to fit in the available space.
 
Maybe there are other ideas, but that's what comes to mind so far...  No idea about the Vixen shaft.
