Hi Keith,

My system has OS Version 20H2 Build 19042.804 and ExploreStars works fine. Windows 10 Professional.
It appears that you are using older builds. It appears that you are using version 1909 with build 18063.

Some very nice galaxy images from you guys
I never seem to have much luck with them! 
I'm Just about to change back to the newt and have another go this year.
I was keeping the 72ED on the PMC to grab Andromeda but I'm not satisfied with any result yet.

Anyway I thought I'd share my last 72ED shots with you guys.

These are all pretty much processed the same as I usually do 
About 3 hours of data re-stacked in sharpcap using the monitor folder Cam
then I use Darktable and Gimp
Filter = LX eXtream  Cam = ASI294 MC PRO

As usual the, PMC mount performed very well :)

These are all small jpegs to save space space on the server!
Cheers!

I believe you missed my point.  I never said I was using ExploreStars on my Windows devices to do imaging.  That clearly was a wrong assumption by you.  I said that since I already use my Windows devices for ASCOM use, I wanted to continue to use my Windows devices for ExploreStars as well (for when I am just out there doing some observing and keeping things very simple.  Simple observing, such as using ExploreStars, is NOT what I would call the user experience when using ASCOM.  ASCOM has its purpose and that purpose is allowing multiple programs to link to one mount, one driver, which is not a simple observing thing like ExploreStars.  So do not direct me toward ASCOM in place of observing with ExploreStars especially considering ExploreStars is one of the primary reasons I purchased the iEXOS-100 over two years ago.  

There is always room for improvement and growth with any app and ExploreStars (on ALL platforms) is not exempt from that.  If you stagnate in the marketplace, you lose.  If the Windows ExploreStars app stagnates, I will naturally prefer to find a mount that is not being put on the back burner in some respect and I will subsequently look to replace my PMC-8 future expansion plans in my own home observatory.  

For what it's worth, using CDC as an example of "very good software" is not furthering your point either.  I despise CDC.  It is a clunky, old program with an absolutely frustrating user interface as well as an unappealing graphical interface.  Again, my comment was not at all directed toward ASCOM use anyway.  I am all set there with better programs.   My comment was directed toward observing with ExploreStars on Windows tablets.

Why do I insist on using Windows tablets?  I use Windows tablets to keep variables to a minimum.  I use Windows desktops/laptops/tablets for ASCOM, therefore I prefer to use Windows tablets for ExploreStars.  I don't use my Windows tablet solely for ExploreStars so I naturally desire compatibility of my tablets for all the data and software that I use on my desktops, laptops and tablets.  It is a matter of consolidating all my computers for more effective communication between those devices.  

One of the things that drew me to this product a couple of years ago was the diversity of the product's future.  My comment was due to disappointment in seeing that diversity waning recently which has been pointed out in this thread.

As far as your recommendation of ASIAir...  again, I was not commenting on the stagnation of Windows development as related to imaging.  It was about observing using Windows tablets using a program I enjoy, ExploreStars.  Also, why on Earth would I now want to start getting involved in such a closed system such as this ZWO-only closed system?  I was drawn to the PMC-8 system because it was an open system available on all operating systems.  As far as ASIAir...   I would rather support Stellarmate for all the points mentioned already.

Unfortunately, this thread is turning me off all the more in sticking with and supporting the PMC-8 system publicly as I have been actively doing for two years.  I believe I am done with this thread now.

To Jerry, thanks for the honest feedback and info.

Patrick

Hi Keith,

It appears that since you just joined the forum recently I am curious if you have even tried to get help with your mount over the past 3 years. How many times have you actually used your PMC-Eight over the past 3 years? That's a long time to "slowly lose interest". 

This forum is not intended to be used to complain about the PMC-Eight system and/or promote other manufacturer's mounts, which your post does. Please see the terms of service for this forum for details..
Is there anything specific we can help you with on your PMC-Eight?

Re: Android and Amazon Fire ExploreStars has been updated #ExploreStars #ExploreScientific

Luke
 

Good morning Jerry and Patrick, 

I agree totally with Jerry that ES  have to move their effort on the Android tablet and other portable platform. As long as you have ASCOM you are all set for windows.  More so now that the soon to be released updated ASCOM driver will have much better specs with improve ease of use. 

Explora stars is better suited to small tablet, quick visual observation,  not for imaging.  There is very good software out there ie "cartes du ciel" only to name one , that works perfectly fine and tracks extremely well using windows base computer.  The use of the ASIAIR, another way to do imaging, is a great match with the PMC8  system. 

My original question was more related to combine the database and software in explora stars for ease of use for newcomers to the platform, I had no intention to criticize the hard work and great support that Explore Scientific offers.

Clear skies to all. 

Luc

Deciding that there is no pressing need for updating the Windows version of ExploreStars is very disappointing to me.  I have no use for Android and I definitely have no use for iPad.  I already use Windows for the serial connection and astrophotography so I have been hoping for continued upgrades and support for the Windows platform for ExploreStars.  Maybe I am in the minority but since I use ASCOM with Windows, I use Windows for ExploreStars too.  

This comes as quite a surprise to me and gives me something to seriously think about for the direction to go in the future.

Hi Patrick,

I think you have mischaracterized the reasoning behind us not updating the Windows version of the ExploreStars application. We understand there may be a pressing need for some customers to have ExploreStars on Windows if they believe that there is no other "better" software available to control the mount, but our customers that think that have to also understand that we are a small company and we have to manage our resources to help out the most customer's. We are very gratified that the ExploreStars application has such a great following. The issue we face is that we have been very effective in developing the PMC-Eight system into a highly flexible system that affords our customers a large number of ways to use the PMC-Eight system. This results in us needing to provide tools for a very diverse set of customers and taxes our resources even more.

We are continuing to move further in that direction today which makes it even more difficult. As you know, our PMC-Eight system is available on on a mid to high range system (depending on your point of view) the G11, and also on the most inexpensive, full featured mount system, the iEXOS 100. There are challenges everywhere when doing this as we have customers who have never used an astronomical mount before to those who have several decades using these types of systems. As I said, we have to manage and prioritize our work to benefit the most customers and unfortunately the Windows ExploreStars application has not been the priority. Those are the facts. Rest assured that we still discuss the need to upgrade the Windows version of ExploreStars, but we are also moving forward to to try and improve the system so that we can make ExploreStars and it's predecessors available on all platforms, not just desktops, and tablets, but on other mobile devices such as the iPhone.

The bottom line is that is is more of a matter of priorities given the resource restrictions we are dealing with, it's not because we don't think it is important, we just think that there are more important tasks which we have to work on which help more of our customers. 

Thanks

It's very straight forward. Just get a serial cable with a FDTI chipset, and reverse the Tx channel. 

You can find more info in the  PMCEightApplication subgroup. No discussions about that here. Jerry won't like it.

locked Re: Guiding questions

Mirko Gude
 

Hi Jaimie,

thanks a lot for your description and remarks. Indeed, the focus of the guiding scope could be better. I will take care about this next time. Sometimes I adjust the guiding scope during daylight, maybe I moved it out of focus and than I forget to focus again during the night. Balance could sometimes also a little bit better. Very often I change something and than I forget to rebalance the scope again.

Best,
Mirko

Hi Mirko,

I'm also fairly new to astrophotography, but I am also using the same software setup as you with the ES PMC-8 iEXOS-100 and included a screenshot below. Your RMS numbers are very high.

The first thing I noticed with your screenshot is the focus on your guidecam - it is very out-of-focus. While the guidecam is more tolerant to being out-of-focus, a 2-second exposure should show pin-point stars.

I guide with Via set to "ES iEXOS-100 PMC-Eight". This uses the USB cable for pulse guiding. I have not tried to use the ST-4 cable at all. It is not a part of my setup.  

The five biggest factors for successful guiding, so far:
1. Balance - ensuring that the scope is balanced in both RA and Dec, using the instructions in the manual.
2. Guidecam Focus - Having pinpoint stars reduces variance between exposures, increases accuracy.
3. Box Size - 16 has worked really well for me
4. Star selection - A star that is bright and stretches to the box size is ideal.
5. Remove Guidescope Flexure - make sure the guidecam is mounted securely to the primary scope. Mine was a little loose, causing maddening issues when the slightest bit of wind hit the scope and wobbled the actual camera.

I hope this helps!

Best, 
Jaimie

Hi,

because I've made some progress in setting up my equipment, I'am now able to spend some time for guiding. At the beginning there was no time for this, there were so many other questions so solve :-)

In the past months I've made some attempts to use guiding to achieve longer exposures. I'am using Indi/EKOS with a Raspberry Pi and EKOS provides a guiding function. First, I had the idea, that guiding will compensate a rough polar alignment, but after some attempts, I think that a good polar alignment is also important for guiding :-)

Very often I get a message like this:
"Guide DEC: Scope count not reach the start point after 21 iterations
Possible mount or backlash problems"

How could I check, If I have a issue with the mount (iEXOS 100 in this case)?

There are also two options to use the guiding camera. EKOS offers "via Camera" or "via ES iXEOS 100" in a menu. I've chosen via ES iEXOS 100, because i was to lazy to search the cable. My second question is, If it makes an important difference If I use this way or If it is better to connect the guiding camera directly with the mount (from Autoguider (ST4) Port camera to Autoguider (ST4) Port mount) ?

Third question is about the guiding rate. EKOS has an option for this and the default ist 0,5. Should I change this? (s. screenshot, it shows also the setting for guiding via, but this is in german). I found in the PMC_Eight_ProgrammersReferenceManual that the sidereal rate is 48. So maybe I should adjust the value to 0.48?

I will also attach a second screenshot, in this case guiding was working for some time. Maybe somebody has a hint what I could improve? 

Thanks and best Regards,
Mirko
