Re: IEXOS 100, ASIAIR, SKY SAFARI #iEXOS-100

Hi Wade,

Do you use ASIAIR with iExos for sidereal tracking?

I am having the same setup like yours, iExos with ASI AIR pro.
Goto works without any issues over serial, but there is no tracking even though tracking is enabled on the asi air app on telescope setting.

Let me know.

Thanks,

Hi Harry,

Thanks for responding.

I actually have tried to access the mount through both Android and IPad. I usually use android.
In both platforms, the behavior is same. There is no tracking.

With ref to your ZWO document reference, I had already got the serial port switch done and am successfully connecting to the serial port over a USB cable. I am able to control the mount like a goto mount where I am able to slew to targets without any issues.

But the biggest problem is where there is no sidereal tracking control from the app to mount though tracking is enabled on the app. This is only with ASI AIR. I have tried the mount over serial to a computer and tracking works as it should over POTH.

Thanks,
-vijay

Hi Vijay, I am assuming you are controlling the ASIair with a tablet.If so, iPad or Android? I know when I use my iPad with ExploreStars, I must be careful to not let the iPad ever sleep, or have any other app running in the background. ExploreStars must be the only active app. So probably the same when running the ASIair app. Android seems less fussy. So perhaps its a tablet interface issue.

Secondly, have you seen this document from ZWO (see attachment). Especially the beginning about 
Explore Scientific PMC Eight Application Note PMC-8 AN003. 

Hope this may be helpful.  Harry

Re: Issues with tracking on iExos 100 with Asi Air Pro #iEXOS-100

I came across this thread

https://espmc-eight.groups.io/g/MAIN/topic/iexos100_tracking_issues/34540664?p=,,,20,0,0,0::recentpostdate%2Fsticky,,,20,2,40,34540664

which refers to issues with iExos and asi air.

I confirmed the firmware version on my mount was also ES1A10B2.
I flashed ES1A10B5 which was the latest from the eeprom downloaded through PMC eight config manager. I didn't see any difference atleast on the green light being consistently on just accessing air app. It behaved the same way, when the telescope settings page was accessed, where it became green and went off immediately as soon as one exited the page.

I will try to do some more testing and see how things look with the newer eeprom.

Thanks,
-vijay 


Re: Issues with tracking on iExos 100 with Asi Air Pro #iEXOS-100

Jerry,

What could be the issue then?

I notice the green light coming on when I am on the telescope settings on asi air. I will try to wait and see if it does any tracking in this mode.
As  soon as I move out of the page, the light goes off. I have usually noted that when tracking is happening through other means (POTH or explore stars), the green light is on consistently as long as those applications are tracking.

Thanks,
-vijay

The iEXOS 100 mount firmware does not stop the tracking like the G11 or EXOS2 mounts. There is no "a" version firmware for the iEXOS 100. That is not the issue with your ASIAIR, it is something else.

What is the "a" version and where can I get that?

On PMC eight configuration manager, firmware tab I see a bunch of eeprom listed some referring to the mount type. Is the "a" version one of them?

Thanks for responding.

I believe this is a common condition with the asi air. The solution is to load the “a” version of the firmware into the pmc8. That version tracks continuously without being continuously pinged.  The other version stops when it thinks it is disconnected.  Asi air does not keep that version alive but the “a” version works well.

Issues with tracking on iExos 100 with Asi Air Pro #iEXOS-100

vijaysam@...
 

I have got asi air pro connected to iExos 100 over serial and am able to access the mount through the asi air app. I am able to control the mount as well being able to slew to an object etc.,

The problem I have is sidereal tracking does not seem to work even though the tracking is enabled on the app to track sidereal.

How could I get the mount to track through asi air pro?

I have tried to connect the same mount over serial to a computer and using POTH, I am able to see that tracking works without any issues.

What is it that I am missing in asi air pro where its not tracking proper?

 

Thanks,

-vijay


Re: Explore Scientific EXOS-2 PMC-Eight GOTO Mount illuminated polar alignment + 90 degree polar alignment

Doug Doonan
 

Hi Brian,
 This sounds really neat and it is like what I want to do. Some questions:
Ursa Major is the big dipper, and it is big in the sky. What part of the BD do you use to align with what part of the reticule? The reticule has a bucket shaped arrangement of little circles opposite where Polaris is, at least in my scope. Is that what you align with the bucket in the  BD?
Casseopea (sp) is on the other side of of Polaris from the BD. I don't see how you can use  one OR the other to get a  Polar alignment. If you use the BD the NCP will be to the left of Polaris. If you use CASS the NCP will be on the right side. Only one can be correct, I think.
Great method if I could understand the details.
Comments?
Doug Doonan

Hi Doug, my modus operandi doesn't worry about putting stars in the reticle circles. I eyeball either Ursa Major OR CASS. (either will do). I then rotate the reticle of the PS carefully until the orientation of the real constellation and the reticule constellation are the same. I then physically move the mount and lat adjuster until Polaris appears in the reticule. Additional careful mount adjustment is done until Polaris is positioned in the little gap along the line marked Polaris. I then power up my mount and away I go.
Please note I am using the iEXOS100 PS, yours maybe different.

Hope that helps, Brian

Re: Cygnus Loop #G11

Bill Black
 

Hi Jennifer,
So I took your advice and modeled my optics in Stellarium. It looked like I could get a lot through my 80mm APO and decided I would give that a shot. Then Isaias rolled in and brought all of the water from the Gulf into Georgia for weeks. Finally a break last night and I was able to give it another shot. Here's what I got; had to do quite a bit of stretching in Polarr, given how bright the sky was with the waning full moon.

Mount: EXOS II with PMC 8
Scope: AT 80mm APO with 0.8 reducer/flattener
Camera: ASI294MCPro with baader moon & skyglow filter
Guider: Skywatcher EVOGuide 50mm with ASI385 
Integration: 12 5-minute subs for 1 hour total exposure

Hi Doug, 
To answer your question. It's the larger half of a .965 eyepiece bolt case.  I'm sure you could use something similar to that or maybe a 35mm film case. It was just something that I had on hand.

This was my solution to this same issue. I found that this Nikon 90° viewfinder for a SLR camera works very well. I simply attached a half of a .965 bolt case over the threads from the viewfinder, then just slide it over my polar scope eyepiece. Definitely a improvement over kneeling on the ground.

Comet Neowise near M53 #astrophotography

Mike Leemhuis
 

During yesterdays podcast, Jerry mentioned that Comet Neowise would be near M53 last night and asked people to supply pictures.  I'll attach my attempt from our Bortle 5 skies.   It was very cloudy but we did have about an hour when the clouds mostly parted and I was able to take pictures.  I ended up with 21 - 60 second exposures.  I processed the pictures in Deep Sky Stacker, using the mode to track the comet, then I used the mode to track the background stars.  I'll include both.  I also used Affinity Photo and Lightroom. The comet is obviously much dimmer compared to a few weeks ago and the tail has all but disappeared.  I am wondering though why it now appears to be reddish compared to the bright green color when it had a tail.  Any ideas?

Re: Explore Scientific EXOS-2 PMC-Eight GOTO Mount illuminated polar alignment + 90 degree polar alignment

Hi all,
The Mount Illuminated Polar Alignment scope in the EXOS2 has a reticule showing Polaris, NCP, and four other little circles that are supposed to be star positions. Does anybody know the names or catalogue numbers of the four stars that are supposed to be put into the little circles?

Thx Brian
Yes illuminated polar align scope solved, batteries dead boughtonly new a month ago so....
Getting a few tips on possible solutions, if they don't work, will take the plunge and get a guiding camera. Did not realise at start I would need such deep pockets.
