Ladies and gentlemen The PMC Mount at its best!
I have just started imaging the bubble nebula, the guiding in PHD is below 0.5 RMS!  0.44 RMS to be precise
That is  with a 8 inch 200pds sitting on top of it (1000mm FL) along with guide scope/camera , red dot, laser,,etc..
if there are any doubts what your PMC mount can do , here is the proof.
this is just about 10mins of exposure time!

How bout that mount!
Cheers!

Dave

Hi Michael,

Thanks for sharing your image. I must however point out that this is the PMC-Eight forum. You don't appear to be using a PMC-Eight mount so this thread is not related to this forum.

Kent,
I’m using the new Raspberry Pi4 with 4gbs of ram and I have it booting of off a 120gb SSD drive, with the drive it boots up 5-10x faster than of off the micro sd card. I’m using it with Kstars/EKos for my visual and Astrophotography needs. The system works great because it only needs 5 volts and less then 3 amps to run it, it’s great for a portable set up. I connect through either my IPhone or android tablet thru VNC viewer, the only down fall I see is that sharp cap isn’t available on Linux so I do bust out the laptop to get polar alignment, you could do thru PHD2 but I like sharp cap better, EKos also can plate solve as long as you have an internet connection. But so far I like the setup, it’s light and amazingly pretty powerful for something no bigger than a credit card. I also run the Astroberry version of Linux which is Raspian with astronomy software installed for you, as well as INDI, so no messing around with ASCOM and drivers.

Looking at a new scope atm. But what I don't get is this;

If you buy a big scope and add a field flattner, or reducer what is the benefit of droping focal length? Wouldn't you just buy a smaller scope? I'm 100% sure I have missed something lol! Thanks

Shailendra 

This is a good question

1.  The larger the aperture the more photons you collect per unit time 

2.  The shorter the focal length the larger fov of a fixed pixel size in the imaging camera

3.  The larger the aperture the smaller the diffraction limit of the scope which governs the smallest resolution.  Small aperture of 80mm has about 1.7” resolution limit.  A 127mm has about 1.1”.  A 152mm has .92”.  Some image with a 51mm which as a resolution limit of 2.7”. Note seeing limit is somewhere between 1” and 2” most places, seldom as low as 1”

4.  We want to match the effective pixel size to the overall seeing of the atmosphere.  Also pixel size (in arc seconds) should be matched to your guiding performance.  In general we presume guiding has small errors and thus adjust our imaging train to optimize the pixel size to our atmosphere seeing.  There is no need to sample the image more than twice as good as the seeing allows.  Note I am assuming  we have a scope for which the diffraction limit is about the same or smaller than the atmospheric seeing 

5.  Sooooo.  We use a big aperture to shorten our exposures times.  This  relieves pressure for long guiding performance.  It is also important if you are using narrowband filters to reduce those exposure times.  We use a focal reducer to change the focal length to adjust the image scale of a camera pixel to better match it to the seeing and diffraction limit of the scope.  In practice if you have about a 120mm or larger aperture your diffraction limit is not a concern.  ES 127 is perfect.

6.  If the scope has a long focal length, the pixel scale is small.  This is a waste since your image resolution is limited by the seeing. It also limits your overall field of view unnecessarily.  Thus for long focal length scopes we use focal reducers to optimize both our field of view and pixel scale to seeing limits.

7.  Field flateners don’t do much to the resolution, but rather it corrects distortion at the edges of the lens field of view.  Often flateners are included in the optics of focal reducers.  

So these points address your question and add up to a set of parameters you have at your disposal to tune your image train to achieve your goals. Understand these considerations are relative to imaging deep space objects.  Planetary imaging has a different set of considerations which would make another email.

In general I feel the sweet spot for imaging is about 900 mm fl.  For DSLR cameras this yields pixel scales at about 1”.  There is no reason to go to longer focal lengths.  At 127mm you get enough photons to be able to expose at relatively low gain (iso 320) for 3 or 4 minutes for your subs and take nice images for many many DSO.  If you can get a larger aperture with a focal length in this range (with or without a focal reducer) and it is light enough for your mount then larger is good.  The exos2 ends up being able to handle a wide range of apertures as evidenced by the forum equipment lists.


For visual, aperture is king.  Your eye needs photons.

Hi Bogdan,

thanks. After flashing the FTDI chip the connection from EKOS to EXOS2 works via serial. And surprisingly: I was able to switch back to Wifi with the flashed cable. I used CoolTerm, there is also a version for Raspberry Pi. That’s nice, because so I don’t need an additional cable ;-)

Some notes for people who wants to try the same with a Mac and VirtualBox:  After flashing the FTDI Chip the cable was not recognized from the Virtual machine. Only unplug or reboot did not help, but after reassign the cable in the VirtalBox USB settings and restart, the flashed cable with the changed setting was shown in FT_Prog.


Best Regards, 
Mirko

Regarding the 5 minutes, I managed to do that with a very good PA. Used the PA from ekos tool. Don't forget to download the all the astrometry index files. You need the 64gb on the pi for all the files

Hi Bogdan,

your input is very interesting for me.

Today I’ve made some progress. I updated my EXOS2 to the latest firmware (firmware = 6B09T17AEXOS2) . As a Macuser it was not so easy, but after preparing a Win10 Machine with VirtualBox and the very useful helper tool PMC8_ConnectionManager I got success. 

I’ve used a FT232R USB UART (FTDI Chip) serial cable. After firmware update I switched to serial via terminal on the Raspberry Pi. But than I was not able to connect Kstars/Ekos over serial. With cuteCom on RPi I was not able to switch back to Wifi/TCP.

After this I’ve tried some other options (PMC8_ConnectionManager and P8-Parallax-Serial-Terminal on the virtual Windows machine and CoolTerm on the Mac). It was a little bit confusing, because after ESX! I got never the response ESX1! But never mind, at some point the Wifi connection was back again ☺ So maybe the command works in the background without showin a response.

Which cable do you use for controlling the EXOS2 via RPi4? Is it a normal one or a FTDI Chip cable? 

I found also a thread about flashing the FTDI Chip cable. 

Do you use a flashed cable?

And wow! 5 minutes unguided sounds really good for me. I’ve also made some attempts with QHY Polemaster and RPi4. But at the moment my results are not so good.

Thanks and best regards,
Mirko

Hi all, 

Sorry for the late reply first of all. 
I will reply to the post even people have already provided some answers.

Equipment used.

RASPI 4 with 4GB 64GB storage
Exos2
Main camera Nikon D610/Nikon D3100a
Guiding camera ZWO 120M
GPS module for Location and Time Vk-162 Glonass Navigation Works
Scopes TS420 / William Optics Spacecat

Connection Method
Serial, because reliability and old school using fdti cable.

The story:
I'm mainly a Linux user and also for me was a challenge to switch the mount to serial. You can use the  terminal to connect via serial cable and run the ESX! command to switch to the com mode.
To switch back you will need a normal serial cable not programed fdti serial cable. The issues comes when you want to upgrade the firmware. For that I have an old windows box.
Connectivity to the raspi i do via VNC from laptop because the screen is bigger on the laptop but i monitor all using my tablet. Only the polar alignment and acquisition process start i do it with the laptop.
The PA is working for me only using the guidescope/camera. Via Nikon and main scope I failed.
Good thing is that with EXOS2 and a very good polar alignment I managed to get 5 min unguided at 420 mm . Im quite happy with my choice already recommended the mount to some people.

Bogdan

How do you connect the Raspberry with the PMC8? Wifi or serial? If serial, how do you switch the PMC8 to serial with the Raspberry Pi via command line?

And it is better to connect the Raspberry Pi via VNC and control KStars/Ekos over VNC? Or do you use a second KStar/Ekos installation which is connect with the Raspberry pi? (As I understood it, this is also possible)

If you could say something about this, that would be nice!

I will reply to the post even people have already provided some answers.

Equipment used.

RASPI 4 with 4GB 64GB storage
Exos2
Main camera Nikon D610/Nikon D3100a
Guiding camera ZWO 120M
GPS module for Location and Time Vk-162 Glonass Navigation Works
Scopes TS420 / William Optics Spacecat

Connection Method
Serial, because reliability and old school using fdti cable.

The story:
I'm mainly a Linux user and also for me was a challenge to switch the mount to serial. You can use the  terminal to connect via serial cable and run the ESX! command to switch to the com mode.
To switch back you will need a normal serial cable not programed fdti serial cable. The issues comes when you want to upgrade the firmware. For that I have an old windows box.
Connectivity to the raspi i do via VNC from laptop because the screen is bigger on the laptop but i monitor all using my tablet. Only the polar alignment and acquisition process start i do it with the laptop.
The PA is working for me only using the guidescope/camera. Via Nikon and main scope I failed.
Good thing is that with EXOS2 and a very good polar alignment I managed to get 5 min unguided at 420 mm . Im quite happy with my choice already recommended the mount to some people.

Regards
Bogdan

Hi Bogdan,

that’s very interesting, maybe you can describe some details? After some attempts with "Mac OS only“ I’ve bought a Raspberry Pi (Model 4) and it looks very promising.

How do you connect the Raspberry with the PMC8? Wifi or serial? If serial, how do you switch the PMC8 to serial with the Raspberry Pi via command line?

And it is better to connect the Raspberry Pi via VNC and control KStars/Ekos over VNC? Or do you use a second KStar/Ekos installation which is connect with the Raspberry pi? (As I understood it, this is also possible)

If you could say something about this, that would be nice!

Best regards, 
Mirko

Hi Kent, all,

I'm also using Raspberry Pi 4 4gb with EKOS + Kstars with my  EXOS-2.
Doing all orchestration with it from polar alignment, plate solving, guiding and picture acquisition plan.
By now all is working really great.

Kind regards
Bogdan

I also made a DIY hand controller from an Arduino, a thumb joystick and
a small LCD display, usable to adjust the telescope, slew speed,
park/unpark, aso.
I added also a database of sky objects to select and go to from the
controller. Maybe not as fancy as just using SkySafari on a phone
screen, but a bit more fun for people who like customization and DIY
projects.

Hi Pavel,

thanks for your answer. I’ve checked minicom, but then the I found „cuteCom“ which has a GUI and for only one command it’s easier than minicom. With my IEXOS 100 it works.

Best Regards,
Mirko

(Not sure anyone answered here)
Just use a serial terminal on your RPi commandline (screen, minicom or
similar) to enter the command to your USB/serial port.

Hi Vince,

sorry, that was a little bit unclear written by me.

I used nc (netcat) via terminal and I could change to serial mode with
„ESX!“. But after this, the wifi connection is lost and I don’t know how
to switch back using the RPi4.

Regards,
Mirko

Hi Mike,

I am glad you are getting good results with your serial connection. When you go back to the WiFi connection you may want to use the channel selection dongle included with your PMC-Eight to change the WiFi channel on the PMC-Eight. Your local WiFi environment may be interfering with your connection making it drop out. 

Thanks for your kind words, we very much appreciate it.

Jerry,

This is wonderful news.  I have had connection issues with the PMC-Eight wifi since purchasing the Exos-2 a month ago.  I will wait for a bit to try what is on the PDF because with the connx issues in wifi to use the Explorestars app, it forced me to begin to learn APT, plate solving software, connx with Stellarium, and using them all with the Poth Hub and Sharpcap using the serial port.  I am thrilled by the results I have had over serial. Stable rock solid.  It amazes me that when you make a setting change in one program, for instance "Park", it registers in everything connected to the Poth Hub.  Blows my mind, lol.

For one, I truly appreciate your continued support in the forum.  I believe that ES has a terrific product in the Exos-2.  It is my first EQ goto mount and I am enjoying it very much. 

With appreciation,

Mike Forbes

CAUTION: The following information is provided for information only, use at your own risk.
Explore Scientific supports the OpenGOTO Community in making the most use of their PMC-Eight system including making certain modifications to, and maintaining their systems without voiding the warranty. Restoring the system back to the original settings by Explore Scientific may incur additional costs (repair and shipping).


This is a repost of a procedure developed by Karl and submitted to the WikiSubmissions subgroup detailing how to configure your G11 or EXOS 2 (Model 2A-06B) PMC-Eight controller to connect to your existing WiFi Internet router. This has been requested several times over the past 3 years. I took the message thread started by Karl on this and turned it into a pdf document (attached) for easy download.

Here are links to a couple of documents which have supplemental information including the PMC-Eight Programmer's Reference and the Microchip Wifly Command Reference Manual

http://02d3287.netsolhost.com/pmc-eight/PMC_Eight_ProgrammersReferenceManual_Release2_2019_March_07.pdf

http://ww1.microchip.com/downloads/en/DeviceDoc/50002230B.pdf

I must warn you again that you perform this modification to the PMC-Eight at your own risk.
I will be creating an enhancement feature request to Chris Moses' PMC-Eight Configuration Manager to include a function to restore the Microchip RN-131 module back to the Explore Scientific settings. This will take some time to research and implement so in the meantime you do this modification at your own risk. The PMC-Eight Programmer's Reference contains the procedure to restore the RN-131 to the Explore Scientific settings so it is possible to do this yourself, but takes a certain level of technical skill and knowledge.

I want to assure everyone that we will always be here to help you in making  changes to your PMC-Eight control system to ensure you have continued use of your PMC-Eight system.as originally delivered to you.

Thanks for your continued support.
