Hmm, okay. 

 

Does the Device Hub at least show that there is some client connected to it? Should show up in the upper right corner.

I know it’s not checked in the image, but I tried both with and without it checked. I can certainly try again, but it didn’t seem to change the outcome.

 

Thanks

Jerry,

OK. So I connected to my PMC8 module with the DB9 cable. Then I opened ES PMC8 Config Manager and enabled serial mode and disconnected from wifi.


Then I opened the ASCOM Device HUB (replaces POTH in ASCOM 6.5+). Went to setup. Selected the PMC8 ASCOM device. Went into settings and made sure that serial connection was selected.






I was able to move the mount from the HUB console. I then opened PHD2 and connected it to the ASCOM Device as you suggested.



I then brought up the manual guiding control in PHD2 but could not move the mount with the PHD2 controls.



What would you recommend from here?

Thank you

Parag Modi:
Like Jacqui already said, there is an M8 screw in the base of the tripod. Remove this screw and my design attaches to it with an M8x25 mm cylinder head screw. My design has a recess for the head of such a screw. There are some pictures on the thiniverse page I linked to above.
To push the mount left or right, I use two M6x30 mm Nylon knurled-head screws.

I have worked with a 3d printer a lot over the last few years.  Another great material for rigidity and strength are the Nylon filaments.  Once you are able to tune your printer in to their characteristics they are rigid and very strong.  It is also somewhat slippery in that it is very good for gears and does not bind like abs.

Jerry,

OK. I have both a serial (DB9) cable and a serial (ST4) cable I can use. I have not been able to find directions on how to put the PMC8 into serial mode. Also, in serial mode, does that also disable WiFi?

Thanks

Hi jeverson.biz,

Even though the ASCOM driver can be connected via WiFi, we always suggest that it is better and more reliable to connect via a USB serial adapter cable. The configuration is also better if you use the ASCOM POTH to connect to the PMC-Eight driver and then connect PHD2 and any other ASCOM client program to the POTH. The WiFi may be unreliable for you because of local WiFi traffic and/or the channel that the PMC-Eight WiFi connection is using.

In summary, the suggested configuration that provides the best reliability is to use

a) the PMC-Eight in Serial Mode with a Serial DB9 to USB FTDI chip adapter cable, 
b) the POTH to connect to the PMC-Eight driver,
c) your ASCOM Client programs connected to POTH, and
d) the ASCOM connection in PHD2 instead of the "On camera" connection for auto guiding.

Re: PHD2 stopped talking to my mount #EXOS2 #OpenGOTO #pmc-eight #ASCOM

James Everson
 

Jerry,

I have not been able to get either the ASCOM suite or PHD2 to connect via ST4. ASCOM just hangs or crashes when trying to connect via COM port over ST4. I will outline my connections.

Laptop to PMC-Eight: over Wifi
ASCOM suite: over WiFi
PHD2: connects via ASCOM driver over WiFi
Guide camera: connected via USB

ASCOM command from the ASCOM tools work fine over WiFi, ie: I can move the mount with the "manual" remote in the ASCOM suite.
PHD2 says it is connected to the mount and the guide camera without errors. I can see what the guide camera sees in PHD2. However, if I try to calibrate it fails, something about the star not moving enough. If I bring up the "manual" remote in PHD2, mount does not respond to commands.

All this said, the very first time I hooked everything up, it all ran like it is supposed to, but now it won't.

Thanks

 Hi jeverson.biz

How are you connecting the mount to PHD2? Are you using the legacy ST4 cable? If so, I suggest you connect via the ASCOM driver instead of using "On camera" as it may be that your camera's ST4 port output does not match the factory calibration of the PMC-Eight ST4 port.

PHD2 stopped talking to my mount #EXOS2 #OpenGOTO #pmc-eight #ASCOM

James Everson
 

Hello,
 
I have this odd issue that I can't seem to figure out. Here is a list of what I'm working with.
 
Mount: Explore Scientific EXOS II GT (connected over wifi not serial)
Scope: Explore Scientific AR102
Guide Scope: 190mm (focal length)
Guide Camera: ZWO ASI120MM Mini Monochrome
PC: Windows 10 Pro (all drivers and software are at the most recent versions)
Software: PHD2, ASCOM, and APT
 
When I set this up and ran it the very first time, it all worked as expected. The only difference between then and now, is that I the original setup was with my SpaceCat 51 scope. I changed the scope and ran through the wizard again to make a profile for the AR102. After that, I couldn't get PHD2 to complete a calibration. I did some digging and
in one of the articles I found, it suggested to use the manual controls in PHD2 with a high "sec" (5000ms) to see if it could move the mount and it didn't work. However, when I open the manual tool that comes with ASCOM, that moves the mount just fine as does the regular control software for the mount. I have tried uninstalling and re-installing PHD2. I have tried creating new profiles. I have run through the wizard several times. For some reason, PHD2 doesn't seem to want to "talk" via the ASCOM drivers even though it can see them and connect to the mount without errors. I am writing this from a different computer than the one I use for guiding so I cannot upload the logs from here. If you need them, I can get them. Just wondering if anyone has seen (and preferably fixed) this before?
 
Thanks

1) If you can get a clear shot of Polaris, use an app to see where it's located around the NCP. Then I shine a green laser through the provided "alignment" hole, get Polaris pretty much located where it should be according to the app. Then I actually run a 2 star alignment, and I've gotten pretty crisp 90sec subs. 
2) 30 secs would be VERY reasonable, 1 min, possibly 90 secs.. If, on the other hand you get it REALLY good, then 2-4 mins especially if you're guiding (I am not, yet. Total noob) 
3) No idea. I know my limits, software programming is WAY outside of those limits. 
4) I'd assume so, I haven't tried it. 
5) Again, I'd assume so. To echo others, what target?
6) I know of no discounts. (I got my iExos 100 on telescopes.net (Woodland Hills) and they are still showing some in stock. )


Re: #iEXOS-100 #iEXOS-100

Hi Parag,

I started using my dslr and 300 zoom lens with my iExos 100 a couple of years ago. Here are some thoughts.

Will you be using a 7 inch or better iPad or Android tablet with the ExploreStars app to control it?

Do you have access to a Windows computer for occasional firmware updates?

Realize that the ExploreStars app was intended for visual use. However, it can be used for astrophotography.

Polar alignment is important. The better alignment, the better results. The app PS Align Pro, and an inexpensive red dot finder (Rigel) will help. I’ve found a 2 star alignment works just fine. Balancing also very important.

Exposures: I can get 30 seconds reliably. With a good PA, 45-60 seconds maybe. I did a shot of M31 at 79 seconds, and I was happy with the results. Yes, at longer exposures there may be a little star trailing. You have to judge your tolerance. Remember, this should be a fun hobby.

Planets, No. They are so small, even at 300mm. Moon, yes. 

Stacking, another big variable. I’ve done 10-50. Yes, more are better, but?

At its price point, I think its a great product! With “go to” its better than any sky tracker, and can grow with your hobby.

FYI, I now have an ASIair Pro, and ZWO guide camera, with a 80mm scope. Yes, these are nice, BUT not required now. Maybe for your future enjoyment. With the Pro, 5 minute exposures, PA a snap. Scope not necessary.

There are so many great people on these forums for help and guidance.

Harry

Re: #iEXOS-100 #iEXOS-100

Dear Parag - a few pointers.  

'I have been getting started in AP with my DSLR.  So far I have been doing landscape (Milky Way) on a tripod without tracking by using image stacking approach.  I would now like to start imaging closer DSO (M31 etc) using my DSLR and 18-300 mm lens.  I have seen YouTube videos showing how that can be done without tracking, but I don't want to go about processing 600-1000 images for single object.  I'm interested in acquiring a low entry point tracker specifically iExos-100.  Can the community help me with a few questions to help me narrow down my choice?'

 

1) I see a lot of posts on challenges with polar alignment on this model.  Does a rough polar alignment followed by three star alignment a good way to get long exposures without investing in additional hardware at this time?

I would not try to use long exposures - there are problems apart from tracking - for example, if imaging the Orion nebula exposures of longer than about 15 seconds will 'blow out' the central region of the nebula. The same is true for the centre of the Andromeda Galaxy.  Image attached is of the Sword of Orion taken with 50, 15 second exposures.   I think 30 second or 1 minute exposures would be fine.  Only 60 frames needed at 1 minute for a 1 hour exposure.  Sequator will align and stack these quite quickly.  (See article in Digest mentioned below.)

2) With the above mentioned alignment, what are some realistic exposure times on an APS-C DSLR and 300mm zoom?

I had no problem  with 30 second exposures without star alignment having aligned on the NCP reasonably accurately.   It is good for the image to move across the sensor during the period of the exposure to remove the effects of hot pixels and 'Color Mottling'.  Just keep the exposures short enough so that star trailing is not a problem. 

3) The description says Open source software, but I'm unclear on exactly what portion of software is truly open source.  Is there an IDE and source code available to "tweak" the software?

Out of my league - though I have taught computer programming at University!

4) Is it possible to do planetary photography with long exposures?

No, long exposures are not needed.  BUT, if you have a Canon camera, you can use the free 'EOS Movie Record' program to use it as a webcam and do 'lucky imaging'  to greatly remove the effects of the atmosphere.  See the article in my Astronomy Digest (www.ianmorison.com - note a single 'r')  on imaging the Moon   -  'Using Deconvolution Sharpening on Lunar images captured with a Canon DSLR and EOS Movie Record'  

5) Is it possible to do time lapses?

I do  not see why not.  I think that you will need an intervalometer  ~ $20 on Amazon to automatically take the frames.  But I wonder what objects. ?   

6) Does Explore Scientific offer discounts for first time buyers?

Not that I know of.

I have put up a first 'review' of the  iExos-100  in the digest  which will be added to as I am able to use it more - only a couple of clear nights since I acquired it.  I had no real need to buy one but felt it 'deserved' to be bought as I really liked the concept and engineering.  It is really for use for astrophotography with a couple of short focal length refractors  but, given additional counter weights can support, for example, a Celestron C6 Schmidt-Cassegrain.

There are many other articles in the Digest that could help you on your way.  Let's hope the  iExos-100 is available again soon.

I do hope that this might help.

Cheers,

Ian
