User Manual for Android version of ExploreStars? #ExploreStars #Android #VIDEO

Paul Mogg
 

Hi there, is there a user manual available that is specific to the Android version of ExploreStars? I'm a beginner to astronomy equipment so I need exact instructions as to how these things work, and so far have only been able to find instructions for the Windows version, instructions for installing the Android version, but no user manual for the Android version, which has a lot of differences to the Windows version, e.g. star alignment, new "ENTER" and "OBS" buttons, different functionality on the "SYNC" button. How do you you capture a location?. I know you can work these things out by trial and error, but frankly you shouldn't have to guess and waste your time doing that. Thank you.

Thanks Wes, I have the FTDI chipset and everything else works fine. I’m sure I will find a workaround I just thought I may have a fault. However it’s a computer isn’t it🤔


Re: #FIRMWARE #FIRMWARE

Thanks Jennifer I will give that a try.😊

Roy:

I assume you attempted to update the FW using the Configuration Manager Tool.  Another way to update is manually via Command Prompt.  There are instructions located in the PMC-8 Application Note (AN001).

I had the same problem.  Unfortunately I do not believe there is a cure, just a work around.  

1.  There was a suspicion that it had to do with the ftdi or lack of an ftdi chip set.  I had the failure with both I believe .  But I might be remembering it wrong.  If you are using a non ftdi usb-serial adapter then get one with the ftdi chipset.  If you are an iexos it already has it in there, so look at the next point.

2.  What worked for me was to change the pc being used to load the code.  Not ideal I know.  I couldn’t get it to work using my windows 10 tablet.   It did work in a bootcamp Mac air, and it works fine on my Dell laptop.

Sorry man, that’s all I can tell you.   Find another computer.

Hi All. I am having issues uploading the latest firmware. I have full control of the mount via serial but the response from the PMC manager keeps coming back 'Checksum Error on Com5'
Is this a laptop issue or a PMC8 issue. Here is the log from the PMC manager for each of the uploads.

Any ideas?

Re: Polar alignment and Sharpcap.

Wes Mcdonald
 

Bill:

1.  If you are polar aligned by sharpcap, you have gotten your RA axis parallel with the axis of the earth.  That is step one.
2.  If you are polar aligned, there is in principle no reason to do a 2-3 star alignment. Clear the alignment results in Explorestars and use the mount raw.
3.  If your mount is truly level, especially now east-west tilt, that is step two
4.  If you have cone error, meaning your telescope is not parallel with the RA axis, best to visualize when you are at polar home, your goto accuracy will be poor to the extent you have cone error.  It is best to calibrate out cone error if you need very accurate gotos.  This is done per a video from the Astronomy Shed (https://www.youtube.com/watch?v=WatdQlPp22Y).  This is step three.
5.  If your polar home position is not correct, then your gotos will be off.  You should establish the true polar home position.  I have a paper in the Files section of the Mounts subgroup that shows you how to find polar home.  It does a pretty good job I think, although some have reported variable results.  This procedure answers your question about where the weight bar should be at polar home.  The arrows are close, but may be off for your specific mount and setup.  Note the correct polar home is affected by the level, so establish a way to repeat your level every time.  This is step four.  Note you must restart the PMC8 with the mount at polar home after you do your sharpcap alignment to ensure the PMC8 has the correct north celestial pole ( NCP) reference.
6.  After you do your first goto and center the object you should SYNC your mount.  This will remove most if not all of the RA home error you might have, but DEC disturbances caused by residual cone and level are not removed completely except near the location of the SYNC.  Thus if you are having trouble getting deep space objects in the eyepiece, do a goto to a nearby star, center it using your red dot finder and eyepiece, and SYNC.  Then do a goto to the DSO you want to see.  It will be near about dead center.

The issue Wolfgang mentioned is that if you run the 2-3 star alignment in Explorestars and center the incorrect star, you are not going to get a good result.  All it takes is one bad star and the result is bogus.

The 2-3 star alignment is useful in that it removes RA home error, corrects for level errors, and will also correct for polar alignment error.  It does not do cone error or DEC home error correction however.  

If you have a good polar alignment but your goto is poor, you can still track objects very well, once you find them and center them in the eyepiece.  

I tried to address all of your points. Hope this helps.  2-3 star alignment just takes practice and you do need to get proper set up with respect to DEC home and cone error.

Wes.

Hi Bill,
same happend by me with the Polfinder.
After thinking about this i am now shure i take a wrong star for the PA.

Re: Polar alignment and Sharpcap.

There are 2 sets of little arrows. Are you aligning them for both RA and DEC?


Polar alignment and Sharpcap.

Bill Kinnair <kinnawill@...>
 

Hello everyone, I'm wondering if I could get some help, sort of ripping my hair out a little.
 
I have the EXOS2 PMC-8 and last night I used Sharpcap to Polar align, I set the mount up as usual and adjusted until Sharpcap said excellent Polar alignment.
 
So my next step was to do a 3 star alignment using Explorer Stars, so when I asked the mount to slew to the first star it was way off even in the finder scope, is that normal? So I used the controls to get the star in my FOV and centred it, it was the same for the next two stars way off. so I did the same.
 
I finished the 3 star alignment and when I asked the mount to find an object the object was not centred it was bottom right of the quick photo I took.
 
I've made sure all the information is correct by setting my Longitude and Latitude and also made sure my time is correct, the mount is balanced and level and pointing North. I think I'm doing something wrong somewhere.
 
Also may I ask should my counterweight bar be parallel with the mounts front leg? I have two little arrows on the mount that should be pointing at each other when in the home position but when they are the counterweight bar is pointing to the right quite a fair bit.
 
It's all quite confusing.     
 
Thanks in advance Bill

i sent you a email Salvo. if you could respond that way we can resolve this issue. 

do you have any guiding logs at all that will help me better determine what's going on.

even my mount has PEC as well and with guiding you can over come the pec within the mount.

Hi Jerry! That honor!!. I am new to this system and the truth has been a bit complex for me. I tell you that when I start POTH and connect my mount, even so, I cannot connect the other ASCOM applications, I leave screenshots of my screen to see where I am wrong, excuse my bad English, I hope to make myself understood ...

Hi axlzerox7 (Please see this message: https://espmc-eight.groups.io/g/MAIN/message/3828 )

You need to use the ASCOM program POTH to connect to the PMC-Eight first, and then connect all your ASCOM client programs to the POTH. If you have installed ASCOM Platform 6.5 you will need to reinstall it and select POTH during the install to make it available on your system. The POTH acts as a "dispatcher" for the PMC-Eight ASCOM driver to all the various clients you wish to connect to.

Ive been meaning to add a few images to this thread.   This is my first season really getting into AP.  Ive been battling some guiding issues, coma corrector spacing and even some camera tilt problems, so these images are from from perfect.  I plan to revisit them all again next year once everything is dialed in, and my post processing skills improve.

OTA: Explore Scientific 208mm f/3.9 Newt
Mount: Explore Scientific EXOS2-GT PMC-Eight
Imaging: Canon 77D Stock
Guidescope: Svbony 60mm f/4
Guidecam: Meade LPI-G mono

All images were taken from Bortle class 6 areas, about 25 miles outside of NYC.  Too many images to give detailed specs, but all were in the 30  to 90 minutes integration range.  Emission nebulas were typically captured with a UHC filter, while reflection nebulas and galaxies were taken with a moon/skyglow filter, or without any filter, depending on the conditions.
