Re: Couple questions about the EXOS2-GT PMC8 #EXOS2 #ExploreStars

Tony
 

Hi All -

It took a good bit longer than I was hoping for he skies to finally clear up, but I managed to get out for a couple hours last night.  Despite the strong gusts and sporadic cloud cover, I was able to gain some familiarity with  the new mount and scope.

Sharp Cap was a breeze for polar alignment.  I'll never unscrew a polar scope cap again.
Even with a near perfectly level mount, and aligning the index markers, the go-tos were still quite a ways off, even after syncing.
Plate solving was truly life changing.  Close is good enough.  No need for alignment stars.  Worked incredibly well 90% of the time.
Guide wise, even on a bum calibration (too close to the NCP) PHD was guiding between .2 and .5 arc sec so long as there was no wind.  As soon as a gust came, it bumped up to 1.5 to 2 or even more.  Honestly, I normally wouldnt have gone out in such wind, but I was getting desperate with the poor conditions lately.
The mount did crash the OTA into the tripod on one occasion.  I was quick to shut it down.  Really not quite sure why or how it happened.  I did have a couple programs crash on the underpowered laptop, so that might have affected it, but I dont believe POTH ever faltered, which I assume was keeping track of the mounts location.  With more practice, hopefully I can isolate the cause.

Thanks for all the help and suggestions guys, the new setup shows a lot of promise.  Cant wait for some better conditions.

Tim,

 

Here’s a draft document I’ve written.

 

DRAFT      DRAFT      DRAFT      DRAFT      DRAFT      DRAFT      DRAFT      DRAFT      DRAFT      DRAFT     

 

EXOS2GT POLAR FINDER ALIGNMENT PROCESS

This process outlines how to align the illuminated polar finder scope (SKU PFEXOS2) found in the polar axis with the polar axis of the EXOS2GT mount, whether or not the mount comes with the PMC-Eight motion control system.

To get a close polar alignment, the polar finder scope must be aligned with the polar axis.

 

THE PROCESS

This process is easiest to do without a telescope or the counterweights installed. Leave the counterweight shaft attached because it makes a good handle at a certain point.

With the EXOS2GT tripod set up outside, orient the polar axis with a fixed that is as far away as you can see – a telephone pole, a radio antenna on top of a mount, a prominent tree: Miles is better than 500 yards.

Adjust the tripod height so that when the polar axis is lowered to align with the target object the illuminated polar finder eyepiece is in a comfortable viewing position. Usually this is done while seated.

Remove the polar finder scope eyepiece cover and the screw-in port cover. Rotate the declination axis 90 degrees to open the internal viewing port.

Use the azimuth knobs and altitude control to adjust the polar axis until you can see the prominent object you selected in the illuminated polar scope.

The center of the illuminated polar finder scope is marked by a cross. That marks the Celestial Pole.

Make fine adjustment to the azimuth and altitude to get a specific part of the target object lined up with the Celestial Pole mark. Example: The top of a radio tower.

Unlock the Right Ascension and rotate the head around the polar axis – best accomplished by grasping the counterweight shaft. As it turns, watch the movement of the Celestial Pole mark. If it simply rotates and stays on the target object, then the device is perfectly polar aligned. But if it moves away from the target object as the RA is rotate, it is NOT aligned.

When the Celestial Pole mark is rotated until it’s as far away from the starting point as it can get, stop rotating it and lock the RA axis.

Now it’s time to adjust the illuminated polar finder scope. On the scope is a collar with three Allen screws. These screws adjust where the device points.

NOTE: The three-screw system requires tightening one screw and loosening two in order to keep the system tight.

Using the correct Allen wrench, look through the illuminated polar finder then slightly turn a screw – just pick one and start. After determining how that Allen screw affected the illuminated polar finder, try another screw. Through trial and error you will determine which screws need to be turned to move the Celestial Pole toward the target object.

When moving the Celestial Pole marker, only move it half way back to the target object. DO NOT move it all the way back.

With the Celestial Pole mark halfway back, use the azimuth adjustment and altitude adjustment to move the mark the rest of the way back to center it on the target object.

Unlock the RA and spin it around. At the point that it is farthest away from the target object, lock the RA.

Use the Allen screws to move the Celestial Pole marker back HALF WAY back, then finish moving with the azimuth and altitude controls.

Continue this process until the Celestial Pole marker stays in the same place when the RA spins.

The illuminated polar finder is now collimated with the polar axis of the telescope.

Bob,

I also found that I could sit in a chair and sighting through the Polar Scope was not a big issue. I ended up making marks on my driveway that helped get the mount close to the same spot each time I use it, and then started using Sharp Caps Polar Alignment tool. I have not had to site through the PA Scope in three or four months, since starting with Sharp Cap. 

I did notice however a couple weeks ago that my Polar Scope had come loose, internally. Had to remove it and tighten things up, which means I need to re-align it. i could easily do that after setting the scope up one evening, but I keep forgetting to do it. Have you done a good alignment of your Polar Scope?

Re: Portable Power and PMC-eight

Jim Norwood
 

Using a 12v battery with an inverter plugged into it is what I run mine with as well. My iEXOS-100 runs off a 12v input, so I use a 12v 5A power supply plugged into the inverter. You should have adequate power with a big battery like that. Just make sure you don't draw it down too much, as that is very bad for lead-acid batteries. I try to never let mine read below 12.0v with no load. That relates to about a 50% drawdown.

Portable Power and PMC-eight

Jeff Snell <Jeffery.snell1@...>
 

Folks,
I'm putting together a portable power pack for my astro gear and I wanna make sure I won't fry the PMC eight (or anything else for that matter).

I've seen a few solutions on the web that involve less money but more elaborate technical solutions for a direct DC to DC power source.

I am looking at a different approach that is a bit more expensive but sounds reasonable.  I want to use a deep cycle marine battery EverStart Maxx-29DC (114aH) and an EverStart Maxx 1500W Power Inverter.  Three AC outlets on the inverter for all my gear (minus camera which I'll leave on battery pack).  I plan to run my laptop (small Lenovo), my PMC-eight, and a USB hub. I did the math on the power burn at 12 hours (2x six-hour imaging sessions) and it looks good with114 aH with some to spare.

This seems simple enough but the devil is in the details. Does it look like I'm gonna fry the PMC-eight with this setup?

Thanks,
Jeff

Why i want to change to alternative power: you know, battery's and nature....
In my opinion this is something where the creators of the iEXOS took a wrong turn and they should have made a build in rechargable battery or something

Re: Mount Startup Position #ASCOM #EXOS2

Wes Mcdonald
 

Nico:

No do not upgrade to the newer ASCOM.  There have been people who have that  reported issues.  Stick with the older version.  It works fine.

If you are at polar home, with the screen as shown, then you are at polar home.  If the arrows are not aligned it is because?  Maybe you were  not to start with?  Or more likely the HOME/PARK thing is confusing you.  Remember the PARK position can be changed, the HOME position is at polar home.  I have not changed my PARK position away from polar home.  Heck, I don't even know how.  

1.  When you say you used POTH "home" what did you do?  POTH only has a PARK button.  If you meant you used PARK then perhaps the PARK position has bee redefined.  If you meant "home please tell me how you did that.

2.  Before you do anything else, try using the APT "PARK" button and see where the mount goes.

Re: Mount Startup Position #ASCOM #EXOS2

Thanks Wes, this is really helpful; I’m going to try reconnecting with Wifi to explore stars and reload the ascom stuff.
The picture was of the numbers after I used the poth setup Home function, but when I did that the arrows got completely unaligned. I am also using a serial cable already.

I will try your suggestion. Do you think it makes a difference if I update to the newer ASCOM version?

Thanks,
Nico

OK, so is the picture you sent how it is now, or how it was?  

The pic  looks good to me.  

1.  Dec is 90.  Correct.
2.  Alt is =Latitude.  Correct
3.  Az is 0.  Correct.
4.  RA is 5:02:49.  Upon start up RA is often incorrect like that.  It is because at polar home slight changes in rotation can make a big numerical change.  Don't let it bother you.  First goto will set things right.  

If your goto sends you to the correct position then you are fine.  

If you have different numbers please send them.  

If things are wrong, here is what I would suggest you do.

1.  Switch the mount back to wifi
2.  Set it up and operate it with exlorestars.  See if the starting position is correct.  If so then you know the mount is proper.
3.  If things are good with explorestars, reload ASCOM platform.  Others have had things just not quite work with their install.  If you want to test before reloading, rin the ASCOM diagnostics.  You need a clean run if theinstall is correct.

Also, if you are running ASCOM via wifi, I would say don't.  Get a cable and run it over serial.  It is so much better.  Odd things can happen over wifi...although in truth I have not used wifi with ASCOM enough to know how robust it all is.  But wifi with explorestars can be wonky.  For astophotography you don't need the extra potential issues.

Re: EXOS2 PMC8 axis movement issue

Wes Mcdonald
 

Chris:

Sometimes things work a bit wonky with wifi.  Sorry this happened to you.

In my fooling around with wifi connected PMC8s there are times when motion is incorrect.  USually this is due to something going amiss with the wifi.


Recovery steps:
1.  Try to park the scope.  Sometimes you discover this works fine.  If so you are usually good to go.
2.  Try using the "restore comms link" button in settings.  It is useful 10% of the time.
3.  Shut down the mount and explorestars.  Put mount back into polar home. Restart mount, reconnect to wifi on your tablet, open explorestars.

It is possible that your were binding, but if so you would have heard a racket like a coffee grinder.  No noise = no bind.

It is possible one of the pulleys on the motor or worm shaft needs to be tightened up.  There are grub screws that clamp the pulley to the shafts.  You can reach the screws through the access window in the motor housing I recall, at least for the large pulley.  

Robert Hoskins has written a Hypertune document that describes how to access all the bits and pieces and adjust things like worm/wheel mesh.  It is in the files section of the Mounts subgroup.  If you think things bound up you can make adjustments.  As Patrick noted it is not difficult.  

On an unrelated point.  Once you do an excellent polar alignment it is not really necessary to do a 2-3 star alignment.  This might save you some time if you have to recover after a wifi foul up.

Re: EXOS2 PMC8 axis movement issue

Koen M.
 

I had sort of a similar problem last night with my iEXOS 100.
I setted it up as usual, but when aligning it when i wanted to do one of the axis'es (cant remember which one anymore either :p ) was working with a big delay.
If i told it to go to where i wanted it to go it took a minute or longer before it did what it had to do.
When i finally got it aligned and it was tracking, apparently it didn't track because i have startrails :(


Re: EXOS2 PMC8 axis movement issue

Patrick Maher
 

Power supply problems is the first thing to check after all else that you have already checked.  If using a battery of some sort, a low battery will often cause one axis to drop out first.  

The next possibility is that there is one (or more) spots where your axis is binding and therefore requires some adjusting.  When adjusting for correct tension you really should/need to rotate through the entire range of motion in case there are any of these tight spots of binding.  It is pretty easy to accomplish with the right tools (various allen wrenches...  preferably t-handle types to make the job even easier.  I believe this is explained in detail in another thread and I believe there might be a document in the files section explaining how to do this.  Others more knowledgeable will probably chime in here.

Also worth mentioning is that a mount needing some adjusting is normal so, at some point, you will need to know how to do this adjustment no matter which mount you are using.  Anything mechanical needs periodic adjusting and maintenance.  A telescope mount is no different.

EXOS2 PMC8 axis movement issue

Chris
 

Hi, I had an odd thing happen last night. I've got a EXOS2 PMC8 connected via wifi.

Using ExploreStars for the moment as I only got it 2 weeks or so ago, the last few nights have been perfectly successful imo, polar aligned using sharpcap to 00,00,13, 3 star alignment and 2.5min subs with no trailing.

So last night I thought I'd get up early and try Jupiter. The mount has been in place all day with a reflective cover over it to stop it getting too hot.

The issue was when I was doing the star alignment with each movement set to 9 on ES, one axis moved as expected and the other barely at all (like it was set to movement 0.5 if that was possible) (it was 4am so I can't remember which axis was playing up) You could hear the a slight motor sound but it didn't sound like it normally does.

Both clutches were firmly done up, no wires binding, nothing clashing on the mount, connections checked.  The RA and DEC values on ES were moving whilst slewing but the mount was only moving in one axis.

I may try the serial, but like I mentioned, it's worked perfectly up until last night and I quite like not having another wire, that was one of the attractions to the PMC8.

I did a full restart a couple of times and it sorted itself out, but it ate into the very short viewing time I had so don't really want that to happen again! I've got about 30min of viewing on Jupiter at the moment when it goes between 2 trees!

Any ideas what to check through or was that an anomalous glitch?


Re: Mount Startup Position #ASCOM #EXOS2

nico bers
 

Hi Jerry and Wes,
I changed the park set so now I looked and the dec and ra are both zero in the profile explorer for Ascom. I tried following what Wes said for the order but I think the Ascom Software might be messed up or something else because when I turn on the mount already in polar home and connect it to my laptop, poth thinks the ra and dec and alt az are the same as in one of my first notes with incorrect numbers. From my understanding, I think the mount should assume when it is turned on that it is at Dec 90 and Az 0 and Alt at my latitude as shown in the picture below, but for me it doesn’t and instead it says it is at the strange coordinates I attached a picture of in a prior response. 
What do you think I can do and what do you think is wrong? 
Thanks,
Nico

Your DEC and RA Park Position values are bad if you want PARK to be the same as HOME. HOME is always defined as the North Celestial Pole and is defined as RA motor 0x000000 and DEC motor 0x000000 (zero). PARK is the user defined motor position that you want your mount to be at when you turn on the PMC-Eight. This can be totally different for example if you are "parking" your mount to lay low under a roll-off roof observatory. The thing about a user defined PARK position is that the clutches cannot be loosened or you lose that position. It does not match the index marks on the mount. The HOME position is where the index marks should be close to, they are not perfect though.
