Hi Koen,
I'll jump first I guess. Disclaimer up front:  First forgive me if I am covering anything you already know, and know I'm in my rookie season.  But I'm confident the seasoned vets will jump in should I say something stupid or inaccurate.  I'm probably one of the closest to your skill level having only been doing astrophotography since last Sept.  Like you, I'm not technically savvy.  I'm from Alabama (note the southern accent), an old USAF fighter pilot (think knuckle dragger) and I need pictures (preferably with crayons) with things dumbed down to the lowest level possible. There are quite a few VERY savvy folks on this forum who can speak to our level (as well as a much higher dialect if needed) that will help you get the most out of the mount.

So first, here's a picture of my setup.  
image.png

This is my EXOS2 GT PMC Eight Mount.  The scope is an Explore Scientific ED 80mm Apochromatic (APO) Telescope (~$699 when I bought it).  Great for wide-field shots (Nebulas, starfields, clusters and galaxies).  For planetary, I think you will want something bigger but I'm not there yet having a preference for the wide-field shots.  I have a Celestron 8" SCT thought that I am going to bring on soon.  I heard about the ED80 from Trevor Jones (Youtube channel: Astrobackyard) who recommended it.  By the way, if you haven't discovered him yet, Mr. Jones speaks our language too with a slight Canadian accent :-).  I watch his videos religiously and have learned quite a bit from his tutorials.  Also take a look at Dillon O'Donnell from down under (Youtube channel: Starstuff).  He's easy to understand as well (also accented :-)).  The smaller scope on top is an Orion Starshoot Autoguider and 50mm guide scope combo (~$250ish).  The camera is an astro modified Canon T5i.  I bought it used ($300) and then had it modified by Spencer Camera (~$275) to remove the IR cut filter (that helps bring in the reds of the Nebula/night sky).  You can do the mod yourself (think youtube videos) but I'm unlucky at that kinda thing and didn't wanna ruin my $300 camera investment.  Spencer Camera does mods for NASA so there ya go. Here's the link: (https://www.spencerscamera.com/index.cfm).  Attached to the front end of the T5i is a Field Flattener to round out the stars at the edges of the image field (~$250ish), and there are three extra extensions (maybe ~$15 each) along the image train to get the right focusing length for the ED80.  Also on the mount itself you might notice a rose colored ring (NE corner above the counterweight).  That's an adapter that is holding a QHY Polemaster Polar Alignment Camera (again,  I think around ~$275ish).  Of all the additional/optional things I bought, I found that item to be most useful for me, and the guidescope combo to be indispensable to increasing exposure time and eliminating any elongation of stars in my photos.

Here are a couple more closeup photos for you.

Below is my ad hoc cable setup using a USB Hub velcroed to the PMC eight.  Works like a champ.  The USB hub is connected to a Lenovo Thinkpad (again recommended by Trevor from Amazon for ~$300).  This is where my serial connection (the left most gray/blue USB) from the Thinkpad flows to the PMC eight (big blue connector on the right).  You will be advised to switch to a serial connection from wi-fi to control the scope at some point.  The middle black USB is to my T5i, the gray plug to its right is to my guide scope connection and the other gray USB sticking out the right side is my Polemaster camera setup (long story as to why thenUSB is connected there.  I won't bore you with it).
image.png
Cable Management via a USB Hub.
image.png
Above are the programs I currently run on my laptop.  Cartes du Ciel is my planetarium program, APT controls my camera (and can do quite a lot of other things that I am still learning or will eventually learn, including plate solving), the Polemaster program for polar alignment, PHD2 (which literally stands for Push Here Dummy) for sending minute pulses to the mount to keep the stars from trailing, and ASCOM POTH which in my layman's brain means a translator enabling all the other programs, and parts and pieces talk to each other.  All of these programs, with the exception of the Polemaster Program were free downloads.  BTW, the plate solving available via APT (or whatever program you choose) essentially eliminates the need for having to sync the PMC eight to any stars for slewing.  Again, the way my Alabama brain thinks about it is that you tell the PMC where you are and what the date/time is via your selected planetarium program, then the camera takes a picture through APT, compares what it sees then solves the puzzle.  It then knows precisely where it's at in time and space and where it's pointing and can now be slewed to a target easily.  No syncing required.  I have yet to use plate solving because I'm inherently lazy, have some additional things to download and configure, and have a way around it via a single star sync after a good Polar alignment via Polemaster.  Since getting good at that method, I have yet to have the target not be centered when I slew to it. Of course I am using a widefield telescope so a little error is OK.

All the above said, There are a thousand little nuances/issues I've had to learn/overcome but everyone here is very generous with their time and expertise.  Have fun, be patient, dive in, and let the good folks on this forum help you get it all up and running.  It wasn't all that tough.  The toughest part to me was and still is the tweaking you need to do to get a good/great finished product.

Good luck!

Re: One beginner's guide to getting EXOS2/PMC8 fully operational with ASCOM, Stellarium, SharpCap, ASPS, and ASCOMPAD

 

Hi Wes, 
Making progress, but few questions:
Step 7 in the linked document, when I try to connect the scope through Stellarium via the Telescope control plugin, I just get a “Connecting” status. Is there something I need to do on Poth. Poth Hub is running and I can manually slew the mount using the on-screen  buttons.

Also, do I need ASCOMPAD without a game controller ?

thanks,
Peter

Re: Upgrading my equipment #ASCOM #astrophotography #iEXOS-100 #TECHNICAL

 

Koen,
 
Perhaps it will help you figure out what to do, if we spend a moment on the "why's".
 
You've been told that you need to guide, because the mount's natural periodic error will cause your image to bump around a bit over time, and nobody likes streaky, lumpy stars.  The fix for this is, indeed guiding.  Basically, the guidescope + guide camera + guide software use a guide star as a proxy for the target that your imaging camera is trying to shoot, and in a perfect world, the guiding system sees a change and corrects for it, before the imaging camera notices (and messes up your stars).  
 
As to what guidescope and guide camera are right for you, well, that gets into a longish post.  The right answer will probably depend on the scope and camera you choose for DSO imaging.  More on that if you want it.
 
You will need a mount computer, if you want to guide.  Perhaps a laptop, or a Raspberry Pi, or one of the 'appliance' devices.  You'll run either ASCOM or INDI as platforms, and some mix of client astro-software on it.  Things to ask about and decide on.  Your PMC8 mount is flexible and it is unlikely to pose a limitation.  
 
You probably don't need to guide, if you want to image planets, but you probably will want different scopes for planetary vs Deep Space Objects's.  And perhaps a different camera as well.  The reason for this is that DSO's are usually wide, dim targets usually shot with longer exposures, and planets are tiny, bright targets usually shot with video (lucky imaging).
 
This leads people to use different scopes for DSO vs planetary, as well as different cameras.  Kinda like screwdrivers - one needs to pick the tool that suits the job.  
 
So you probably will want a scope with a wider field of view for your DSO's (and guiding), and something with a much longer focal length (and narrower field-of-view) for planets. 
 
We do have people her that do both here - on iExos100's, and I hope they chip in - but it will probably simplify things if you think of DSO's vs planets as two different problems that likely require different solutions.
 
Coming back to guiding, do figure out what scope you'd want to use for DSO imaging.  Small refractors are popular, but there are other options.  Once you have that sorted out,  this site can help you work out a guide ratio that meets your needs:
 
 
Some say a guide ratio of 1:3 is fine, but I was happier close to 1:2. YMMV.
 
No, none of this has to do with cables - those are things that come after deciding your imaging resolution vs guiding resolution, the software you will guide with, and the device you will run that software on.  Only after that, do you know what your cable needs are, because those things are what you connect your cables to.  :-)
 
Hope this helps...
 
- Bob

Kevin,

If you are standing with the tripod facing north, so the telescope eyepiece is at your belly button and the objective end of the telescope is pointing at at Polaris, the east is on your right, west is on your left.

Regarding the legs, the lower the legs the more solid the tripod. And that solid tripod will help reduce vibration, which will improve the photography.

Hi Jerry..
Does it matter on guiding if the tripod legs are fully extended or not? I have been running my mount with the C8 on top and an Orion 80 mm guide scope with the legs fully extended, do you think I would get better guiding results if I shorten the legs?


Re: EXOS 2 GT Payload Capacity

Kevin Rea <reakevinscott@...>
 

If you are let's say facing the end of the scope, on its mount, which way is east and which way is west?

The polemaster absolutely is great. I use it.  But it does need a view of Polaris and surrounding stars.  

The ioptron iPolar looks to be the same except they perform a plate solve and will get you polar aligned without looking at Polaris.  A friend of mine uses it and it works fantastic also.  Now I believe it is available to be mounted on any telescope mount such as our exos2 mounts, but have not myself done it.  Suggest to research that a bit and add it to your trade space analysis.

The UPLR buttons on PHD only move the mount at the guide rate set in the driver.  They are not meant to skew the mount, they are for manual guiding.   

Here is a short list of thoughts to get you organized 

1.  Get poth up and select the Es pmc8 driver in its setup...you did this
2.  Open stellarium and set it up for telescope control.  This is something you have to read about .  Alex wrote a nice doc on all of this



3.  Stellarium will allow you goto targets and get close 

4.  Once the mount is under your control via stellarium you will have to learn how to polar align it.  This will improve your goto accuracy.

5.  You will have to learn how to level the mount.

6.  You will need to determine the home position to a high degree of accuracy.  You can find a paper on this in the files section of the Mounts subgroup


7.  You may wish to adjust cone error.  A document for that is also in the same directory.

B. Tracking and short exposure imaging < 20 secs
C. Future: PHD2 for auto guiding in the future for longer exposure imaging
 
One of the challenges of such a flexible setup is understanding which components one needs to to succeed. If there is documentation for the next steps, would appreciate the links.

Re: New Purchaser of the EXOS 2 PMC-Eight

 

Welcome!
 
Yes, these are good mounts.  We have folks here using PMC8 mounts for everything from Visual, to DSLR AP, as well as AP with everything from small scopes to  Newt's, SCT's, etc..  People control their PMC8's with everything from tablets to laptops to Raspberry Pi's.  Those run everything from ES's 'Explorestars', through ASCOM and INDI in their various permutations.
 
So... the good news is that the mount is flexible and can handle payload, but the flip side of that is that you WILL have some things that you'll have to figure out.  And that's what this forum is for.
 
If it helps you, there are broadly two 'lanes' to consider when planning out how you will control your new mount:
 
1. Visual + short-exposure DSLR AP.  Someone in this lane would typically use a tablet with ES's 'Explorestars' control program to manage the scope via wifi.  They'd probably run the camera with an intervalometer.  They probably will not try to guide.  They might use the polar scope for PA, but people use phone apps and other techniques as well.
 
2. Longer-Exposure AP + occasional Visual.  Someone in this lane might use a Laptop or Raspberry Pi or equivalent appliance as a mount computer, running ASCOM or an INDI-based solution, and compatible planetarium, guiding, and camera-control software.  They'll likely guide, and will likely use a serial-USB connection from the mount computer to the PMC8.  They may access that mount computer remotely.  They'll likely NOT use the polar scope for PA, and will instead use Sharpcap, Polemaster, drift, etc., for the additional precision. 
 
So, you have lots of room to stretch out. :-)
 
Typical exposure times and focal lengths are pretty varied here, as you can see from the posts, and they do depend on whether you guide or not. I'd be lucky to get 30s out of my mount at 621mm unguided, but 180s, 300s, 600s and better are not a problem when I guide.  That took some time, skill-building, and advice-taking, but that's where I ended up, and I have lots of company.  
 
HTH...

What version of ASCOM are you using, and did it pass the ASCOM test?  After installation you should run the ASCOM diagnostic, it needs to pass every test.  sometimes it doesnt.  If it fails uninstall and reinstall ASCOM.  for now use PLatform 6.4, the old one if you can.

Re: New Purchaser of the EXOS 2 PMC-Eight

My thoughts only...I bought the PMC-eight (plus an ES ED80MM APO telescope) back around April last year as my first EQ mount/tele combo with the intention to use it for astrophotography.  I am not tech savvy at all and certainly not in the astronomy world, having only owned a celestron Alt Az go to for visual observing.  I am mobile and the PMC-eight/ED80 combo is working awesome for me (although my battery setup is a heavy booger).  Lot's of good advice and tech support on this forum and at ExploreScientific to aid me on this trip.  The first thing I bought after initially using an unmodified Nikon, was a used canon DSLR T5i and had it astro modified for the photography piece (IR cut removed).  Second most important thing (I should have bought sooner) was a QHY Polemaster polar alignment camera/adapter with the associated program/software.  Extremely easy to polar align now.  The scope that comes with the mount is good too but a lot more work to get close enough for good astro photos and to figure out what the display means and how to use it properly.  I guess I'm just too lazy and the Polemaster only reinforces that behavior :-). That single ~$250 investment was soooooo worth it.  I get very precise PA now and as long as I have all my parameters entered correctly in my planetarium program (CdC), and then sync on a single star, the subsequent slews nail the targets every time.  Next was an autoguider utilizing PHD2 for tracking and a Bahtinov mask for focus improvement.  In between all that, I left the wifi and went to a serial connection from laptop to mount, bought a few misc parts and pieces (filters, extension tubes, a field flattener) for the imaging train as well as the previously mentioned planetarium program (CdC - Cartes du Ciel), downloaded Astro-Photograpy Tool (APT) and used ASCOM POTH Hub for integration.  

It's that simple :-).  OK, not really simple but well worth it.  I am now taking "decent" photos and trying to figure out the processing piece using photoshop.

Not really a "checklist for perfection" some of the professionals on this site will pass but that's my take.  Use the checklist they proffer, ask and follow their advice/guidance, and you will do great with this mount!

Hi everyone,

Guess I'm looking for a bit of assurance on my purchase of the EXOS 2 PMC-Eight yesterday.  It's being discounted anywhere from $100 - $200 and have a few days cancellation window.

My desire is to start with nothing more than a DSLR and lenses ranging from 20mm - 300mm to reduce ISO and extend exposure for AP but future proofed to eventually slap on a modest scope for visual and AP work as my knowledge grows. 

I've been out the picture for decades and parsing through the discussions the digital world of astrophotography is both stunning and frankly a bit intimidating in the myriad choices, a far cry from the film days when I was gas hypersensitizing Kodak Tech Pan 2415 on a LX5 eyeballing 30 minute exposures with an off axis eyepiece!

I'm looking through the discussions and it's not sinking in yet but hopefully you can jump start me.

Is this mount a good first start for my intentions?

What would be the first accessories to consider hardware/software for a newer user related to making PA easier, improve ongoing guiding accuracy, and image enhancement?

Will the included polar finder scope be sufficient?

I plan to go mobile with the equipment.

Thanks!
