Bob,

I'm doing a write up but you probably don't want to wait.

This is a quick and dirty version of what I did (and assumes you've installed and added your geo, time, telescope, eyepiece parameters, etc.):

1) Installed Kstars - I don't like this program, but it includes the INDI pmc-8 driver you need for your Mac to talk to Stellarium. I don't recommend installing INDI drivers any other way on the Mac, but you can try if you want to remain frustrated
2) Start up the INDI control panel in Kstars and select your mount (EXOS2-GT), then run a local service on port 7624 (this is automatic after you Run the service)
3) Connect to the pmc-8 wifi
4) Connect the INDI control panel in Kstars to the pmc-8 - you have to set up the connection controls from the Configuration menu first (select Ethernet, TCP - the port that is listed is the default - leave it alone)
5) Start up Stellarium
6) Activate the Telescope Plugin in Stellarium and select the Telescopes tab
7) Configure the Telescope Plugin - select Telescope controlled by - INDI/INDIGO radio button
8) Scroll down to INDI settings - you should see localhost 7624 in the Host settings, click Refresh Devices - you should see "ES EXOS2-GT PMC-8" appear in the devices window
9) Click OK and go back to the main Telescope Control window
10) Click Connect - you should now see "Connected" status under "Telescopes Controlled" window for your scope

You're now connected to the PMC-8 with Stellarium on your Mac.

One disclaimer - Stellarium won't solve your alignment issues, but it does help me find things in the sky. Stellarium has a virtual hand controller that you can use to slew your scope to look for things you want to see until you get polar alignment issues sorted. It also has the usual goto features.

Hope this helps.

Do you mind sharing your current PHD settings (assuming you are using PHD).  I tried my 8" SCT about a month ago and had horrible star trails.  I wanna try again but would like a baseline to start with.  Sounds like you have one.

Sorry Dave. I was so overcome with the image I lost ability to type.  Really nice.  Sharp focus to, what with the spider flare and all.  I love to see those things on the bright stars in a nebula picture.  Some see them as an issue, but not me.

 

You do anything special to get .5” guiding?  You guiding ra and dec?

Re: EXOS2 GT

Explore Scientific takes the position that third party software is not something they support.  In the case of ascom they made and support their driver to enable use of the broad spectrum of ascom compliant clients.  Most users in the forum doing astrophotography use this capability and it works very well.  Notably PHD2 for guiding.  Astrophotography programs     from many sources are used to manage imaging and indeed overall site and process automation.

I am unclear where the indi driver came from.  Multiple users employ it, Steven being one.  There are sufficient now on the forum who are willing to assist Mac users.  

I am a Mac person but I threw in the towel for my mount computer and employ windows on a boot camped Mac mini.  My experience with windows on macs is they run Windows better than windows boxes...:). 

In the windows world there are just so many applications, and the ascom group is well developed and the platform very stable.  

One thing I do to make my life better is run the Mac mini from my iMac over RDP.  Works like a charm and the screen resolution is great, plus I can hang out inside while the mount does the freezing.  Mini takes some power though.  For star party use I still have my Dell laptop.  Not sure it is less power tho.

Anyhow that’s kind of the big picture.  Maybe Jerry or others can clarify the ES position on indi.

If you asked me what operating system to start with I would probably recommend you start using the PMC8 systems with ascom on a pc.  This is partly because the huge preponderance  of people seem to use the PC and can help.  But I surely understand the desire to use macs.

Hi all,
I got some decent footage of Jupiter and Saturn last Friday (early in the morning, like 4 AM).
I wanted to share some of the technique and processing steps.

The set-up was:
Scope: Celestron C8 with a 3x Celestron X-Cel barlow (so an effective focal length of 6096 mm; these X-Cel barlows are nice; I get no chromatic aberration through mine... I do get some, but its all from the SCT itself).
Camera: ASI385 (standard, not-pro version)
Mount: EXOS II with PMC 8 (Although you could certainly do this with iEXOS100)

The seeing was pretty good, so I shot 100ms frames (10 fps) in SharpCap for about 50 seconds (gain 200, RAW8 color space).
Of the 500 frames shot in the sequence, this one is the single best frame according to AutoStakkert:

I used AutoStakkert to stack the best 77 frames of video (that's where the quality rating dropped to 80% of the best above) to get this result:

Opened the stack of 77 in Registax 6 to use the Wavelet editor to bring out finer detail to get this result:

And finally, used Polarr to touch up the color, rotate, and crop the image:

Good advice from folks.  As for using the Big Dipper stars...one will be good but please don’t use two.  Alignment calcs need more separation, especially in Ra.  The app generally does a good job of getting things spread out but if you skip through the list and use two or three stars near one another the calcs get ill conditioned.  This can lead to poor performance.

Take a look at those alignment coefficients...you can turn on their display in the iPad in the settings area for Explorestars.  I think the button says show alignment coefficients or some such.  They appear at the bottom of the data displayed on the main screen.

Bob,

I'm doing a write up but you probably don't want to wait.

This is a quick and dirty version of what I did (and assumes you've installed and added your geo, time, telescope, eyepiece parameters, etc.):

1) Installed Kstars - I don't like this program, but it includes the INDI pmc-8 driver you need for your Mac to talk to Stellarium. I don't recommend installing INDI drivers any other way on the Mac, but you can try if you want to remain frustrated
2) Start up the INDI control panel in Kstars and select your mount (EXOS2-GT), then run a local service on port 7624 (this is automatic after you Run the service)
3) Connect to the pmc-8 wifi
4) Connect the INDI control panel in Kstars to the pmc-8 - you have to set up the connection controls from the Configuration menu first (select Ethernet, TCP - the port that is listed is the default - leave it alone)
5) Start up Stellarium
6) Activate the Telescope Plugin in Stellarium and select the Telescopes tab
7) Configure the Telescope Plugin - select Telescope controlled by - INDI/INDIGO radio button
8) Scroll down to INDI settings - you should see localhost 7624 in the Host settings, click Refresh Devices - you should see "ES EXOS2-GT PMC-8" appear in the devices window
9) Click OK and go back to the main Telescope Control window
10) Click Connect - you should now see "Connected" status under "Telescopes Controlled" window for your scope

You're now connected to the PMC-8 with Stellarium on your Mac.

One disclaimer - Stellarium won't solve your alignment issues, but it does help me find things in the sky. Stellarium has a virtual hand controller that you can use to slew your scope to look for things you want to see until you get polar alignment issues sorted. It also has the usual goto features.

Hope this helps.

Hi Bob.

I've been having these types of issues as well, and yes it is frustrating. I've since accepted that amateur astronomy is a process.

A few observations:

1) I thought I was polar aligning well, but after reviewing some notes from others here and also looking online, I found out I wasn't. I'm using the Polar Scope Align app available for iPhone which helps, but read the detailed instructions or you'll still be off. Others here don't even use the polar scope but instead opt for other tools (Polemaster, Sharcap).
2) I had some cone error, but corrected this. I posted a document in the files section of the MOUNTS subgroup that explains this. There is a helpful video referenced as well
3) I found out my mount could not be leveled. One of the legs pulls out longer than the other. ExploreScientific made good on this. Check for this, and use a real level, not the bubble
4) You should be able to get Stellarium to work with this mount. Not sure what platform you have, but it works for Windows users and I just figured out over the weekend how to get it working on my MacBook Pro (if you can get Stellarium working on a Mac you can get it working on anything).

Hope it helps.

I have to say I am frustrated with the exos2-gt mount. While it tracks well once you have the target in the viewfinder, I have to say up to that point it is a manual mount.

To start the alignment I level the scope, do a polar alignment, hit park (and check to see it is lined up with the marks when it stops moving), the hit 'reset alignment'.

1/ After polar aligning WELL on a level mount with good freedom of movement I attempted to do an alignment.
2/ Picking a clear, bright star from the list I hit 'goto' when prompted to use it as the first star.  
3/ I locate and center it (the mount gets me within 5 degrees or so) with a 24 mm eyepiece. THEN I Switch to a crosshair eyepiece and line it up perfectly.  Then I hit enter (I tried sync then enter upon the suggestion of E.S. earlier)
4/ I repeat the process for star 2, or star 2 and 3 as appropriate.

I park the scope again, checking the marks.

Then I ask it to slew to Jupiter, which is clearly visible.  The magic of the mount occurs, and when it stops slewing, it is 90 degrees to the west of Jupiter and angled toward the ground.  I carefully check the clutches to make sure they were tight, and watched the scope move to make sure no cables were caught.

I park the scope, hit reset alignment, and repeat a full 2 and 3 star alignment as above.

Once again, I ask it to slew to Jupiter.  When the scope stops moving, it is pointing to Mars, nearly 90 degrees off Jupiter to the EAST.

Seriously, I'm new to astronomy, am computer literate, and I just want the target in the low power eyepiece after spending twenty min aligning the damn telescope.  What is the problem and why do I have to fight this 700 dollar mount to find the MOON????

I'll keep working with it, but this is ridiculous when you look at it.  I should be able to 

a/ Expect to see my target in the low power scope when I ask the mount to go to it.
b/ I should be able to control the scope with Stellarium without an act of Congress and a visit from the geek squad.

I'm going to add a camera and a guide scope and see if they will make this thing work.

But I have to ask, it is supposed to be this absurd, is this what I can expect from a high quality mount like an exos2-gt?  Is this just pilot error?  Is there a secret handshake to make this thing work?  If so, why isn't it in the manual?  Why does the manual seem to be written for another version of the software (windows and a couple of releases ago).  Why, when I follow the instructions, does it simply not work?

If I can't figure it out in a week, I'm just going to send it back and buy a different model that works with stellarium and doesn't have me up half the night trying to align it when I should be using it to explore the universe.

Hi Bob, 
That last part "I park the scope again..." is an unnecessary step and I suspect may be where your problem arises.
If you loosened the clutches at that point (or any point) after the alignment routine, then the alignment will be lost.
Try just slewing directly to Jupiter after you finish the alignment and hopefully it will hit it :)

Stellarium will not natively operate the mount.  You must go through ascom or indi.  Ascom is for pc only.  

Stellarium 19.3 will connect through ascom ok it seems.  Earlier versions needed a piece of bridge software call stellarium scope.  It was mostly ok.

Dave,

Do you mind sharing your current PHD settings (assuming you are using PHD).  I tried my 8" SCT about a month ago and had horrible star trails.  I wanna try again but would like a baseline to start with.  Sounds like you have one.

definitely use a dark frame on your guide camera and get stars as small as poss on there as well.   Yes  I Am guiding both Ra and Dec, total error 90% of the time below 0.5 unless the wind blows my tube!

 

I’m with you, I like diffraction spikes,  good enough for Hubble, good enough for me 😊

Sorry Dave. I was so overcome with the image I lost ability to type.  Really nice.  Sharp focus to, what with the spider flare and all.  I love to see those things on the bright stars in a nebula picture.  Some see them as an issue, but not me.

 

You do anything special to get .5” guiding?  You guiding ra and dec?

Re: EXOS2 GT

Hi Bob.

I've been having these types of issues as well, and yes it is frustrating. I've since accepted that amateur astronomy is a process.

A few observations:

1) I thought I was polar aligning well, but after reviewing some notes from others here and also looking online, I found out I wasn't. I'm using the Polar Scope Align app available for iPhone which helps, but read the detailed instructions or you'll still be off. Others here don't even use the polar scope but instead opt for other tools (Polemaster, Sharcap).
2) I had some cone error, but corrected this. I posted a document in the files section of the MOUNTS subgroup that explains this. There is a helpful video referenced as well
3) I found out my mount could not be leveled. One of the legs pulls out longer than the other. ExploreScientific made good on this. Check for this, and use a real level, not the bubble
4) You should be able to get Stellarium to work with this mount. Not sure what platform you have, but it works for Windows users and I just figured out over the weekend how to get it working on my MacBook Pro (if you can get Stellarium working on a Mac you can get it working on anything).

Hope it helps.

Steve

I have to say I am frustrated with the exos2-gt mount. While it tracks well once you have the target in the viewfinder, I have to say up to that point it is a manual mount.

To start the alignment I level the scope, do a polar alignment, hit park (and check to see it is lined up with the marks when it stops moving), the hit 'reset alignment'.

1/ After polar aligning WELL on a level mount with good freedom of movement I attempted to do an alignment.
2/ Picking a clear, bright star from the list I hit 'goto' when prompted to use it as the first star.  
3/ I locate and center it (the mount gets me within 5 degrees or so) with a 24 mm eyepiece. THEN I Switch to a crosshair eyepiece and line it up perfectly.  Then I hit enter (I tried sync then enter upon the suggestion of E.S. earlier)
4/ I repeat the process for star 2, or star 2 and 3 as appropriate.

I park the scope again, checking the marks.

Then I ask it to slew to Jupiter, which is clearly visible.  The magic of the mount occurs, and when it stops slewing, it is 90 degrees to the west of Jupiter and angled toward the ground.  I carefully check the clutches to make sure they were tight, and watched the scope move to make sure no cables were caught.

I park the scope, hit reset alignment, and repeat a full 2 and 3 star alignment as above.

Once again, I ask it to slew to Jupiter.  When the scope stops moving, it is pointing to Mars, nearly 90 degrees off Jupiter to the EAST.

Seriously, I'm new to astronomy, am computer literate, and I just want the target in the low power eyepiece after spending twenty min aligning the damn telescope.  What is the problem and why do I have to fight this 700 dollar mount to find the MOON????

I'll keep working with it, but this is ridiculous when you look at it.  I should be able to 

a/ Expect to see my target in the low power scope when I ask the mount to go to it.
b/ I should be able to control the scope with Stellarium without an act of Congress and a visit from the geek squad.

I'm going to add a camera and a guide scope and see if they will make this thing work.

But I have to ask, it is supposed to be this absurd, is this what I can expect from a high quality mount like an exos2-gt?  Is this just pilot error?  Is there a secret handshake to make this thing work?  If so, why isn't it in the manual?  Why does the manual seem to be written for another version of the software (windows and a couple of releases ago).  Why, when I follow the instructions, does it simply not work?

If I can't figure it out in a week, I'm just going to send it back and buy a different model that works with stellarium and doesn't have me up half the night trying to align it when I should be using it to explore the universe.

Bob
