You can also use your phone and the PS Align Pro app to get your scope reasonably close to pointing at the north star. There is a bracket that you can use to align your mount with this method. I don't recall off-hand how to find the link, but it is in here somewhere. You have to download the design and have it 3D printed, but it works well.

Hi Dino,
     Welcome to the Exos2 family.  If you connected to Ascom, there is a "button" on their control screen which will Park and unpark your mount.  My best advice is to read everything on the PMC8 forum, take your time and have fun.

Hi all,
Finally received my EXOs 2 PMC8 Mount yesterday after waiting since last December.😁
Definitely worrh the wait. Nice solid construction, plenty of counterweights to handle loads, and the a durable box for the controller.
Was able to operate the mount in all its fundamental parameters wirelessly.
But hit my first snag when trying to control using Stellarium. I know this may be a redundant question, but can someone remind me how to Unpark the scope from ASCOM again.
it’s been awhile since I played around in Ascom.
Stellarium connects and shows the ES reticule at Polaris but when I try to slew,  a pop up asks to unpark the scope.

 Thanks 🙏 in advance for any assistance.

You don't really need to see the little dipper. If you can find the big dipper (should be in a position a little higher than the attached image) follow the line from the stars on the end (Marek and Dubhe) to Polaris. Polaris brighter then the stars surrounding it. 

A star app like Stellarium or skysafari also use your phones compass and will get you pretty close. 

Your latitude will also be close to how high Polaris is in the sky. So that will give you a general idea. Adjust your mount to what ever your latitude is and point it north. You will be In the ballpark

Hi Vance

If you Google “finding Polaris” you will find  a series of images like this one:



Polaris is the only bright star you’ll see in that direction from Merak & Dubhe.

Or, if you can work out what direction is north, from a street map of your neighbourhood, just look north. Polaris will be roughly halfway between the northern horizon and the point directly above you (a bit higher if you’re in a northern latitude, lower if you’re further south).

Hi Vance,
   the two bright stars at the right hand side of the big dipper, Merak and Dubhe act as pointers - just extend the line beyond Dubhe until you find a bright star.  That should be Polaris.

Hi Euan,

There are two ways to connect your mount to your guiding system via the universally used PHD2 Guiding software. You can use the legacy ST4 connector on the mount with an ST4 cable to your camera. This is called "On camera" in PHD2. OR, you can eliminate the use of another cable by using the PulseGuiding API in ASCOM by selecting ASCOM in PHD2 for the auto guiding connection. PHD2 makes use of the USB connection you have to your mount already to send pulses to your mount. 

The ASCOM PulseGuide function is the best way to go. No need to use the legacy ST4 connector anymore.

Thanks to this thread I have installed APT, and it seems to be talking to the mount ,stellarium, and my Canon camera. Not been able to try the plate solve as of yet. 

Once this is working and had a few daytime practises I will try this on my next imaging session.

With Sequence Generator Pro, I enter the RA and Dec coordinates of the target.  There are different ways to get these including from Stellarium, Cartes du Ciel, Sky Safari, etc.  I use a tool in SGP called Framing and Mosaic wizard so I can compose my shot ahead of time and get the desired coordinates based on composition.  Most of the time, the RA and Dec of a target aren’t exactly in the center of what your desired frame is.  

When I tell it to plate solve, SGP slews to those coordinates, takes a picture, extracts the stars, “solves” the image to determine where it actually is pointing in the sky, then moves the scope based on the difference it calculated and runs through the process again for a few iterations until it’s within a set number of pixels if the entered RA and Dec coordinates.  It’s actually quite easy to set up, but you have to know the image scale in arc seconds per pixel of resolution.  A Google search will turn up sites that help calculate this.  NINA, ASI Air, and AstroBerry follow similar plate solving procedures.  

Plate solving will change your life as an imager.  I used to spend a gob of time framing, especially on a multi night image.  Now, with a little planning, I can set up a sequence (or imaging plan) with RA and Dec coordinates, the number of frames, camera settings, etc. and go.  

Sequence Generator Pro has a bit learning curve, but once you get your settings in place, it saves a gob of time.  Others will likely say the same thing about NINA.  

Check out Amy Astro’s videos on Sequence Generator Pro and PHD2.  Cuiv the Lazy Geek also has a lot of good stuff on NINA, plate solving, and PHD2.  PHD stands for Push Here Dummy, by the way.

I know this strayed a bit from your original question about guiding, but I hope it was helpful.

Euan, I will give you another option. I use the ASIair Pro. 
I love it’s simplicity and ease of use. It is controlled via an iPad or Android tablet. No laptop or computer. No Ascom or drivers to install / program. Your Canon 1200D appears to be supported. It will Polar Align, find your target, control exposure, guide,(using ZWO guide camera). No 3 star alignment, so ExploreStars is no longer used. You do need to connect it to your iExos 100 via USB serial cable.
I have a similar setup as you, just a Nikon camera. It works great. You will need some photo editing software (I use Affinity Photo) to stack and process the image.
Just another option.

You will want to use something like Nina or Astro photography tool kit. To run your mount.  You can use stellarium to point to a. Object but you need to plate solve. Nina or apt will run this for you. You can import into them targets from stellarium and manage the goto and platesolving

Now you could do something like this;  get your self physically polar aligned.   Use Explorestars without 2-3 to go to a target.  You can find DSO by going to a nearby bright star, centering and synch.  Then do a goto to the DSO.   Now use phd2 and st4 guiding.  Then manage your camera manually.  It’s a good first step that uses more of what you already know.

Make sure Explorestars is in T mode.

You’ll need a computer running autoguiding software.  Some folks like the ZWO ASI Air.  Others like to roll their own similar setup with AstroBerry and a cheap RaspberryPi.  Both run a flavor of Linux and INDI.  ASI Air is a commercial implementation of INDI.  I prefer to use a Windows 10 mini computer and I use PHD2 for auto guiding and Sequence Generator Pro for imaging.  Some folks like to use N.I.N.A.  I’m doing everything in Windows 10, so my setup depends on the ASCOM driver.

When I set up, I don’t use Explore Stars.  I make sure my physical alignment is solid.  That means a good polar alignment.  I also use a level to center my RA and Dec axes in that order.  Then, I plate solve to center my target rather than relying on a multi star alignment.  The multi star alignment is a pointing model and is independent of polar alignment, which determines tracking accuracy.  Get good at polar alignment and your guiding should be uneventful.

Hope this helps!
