Asiair problems

[email protected]
 

A recent update of my asiair pro left me with a lot of problems, I have resolved most of them but cannot get it to work with my gemini as it used to. Problems are on doing PA, when it rotates the scope it is so slow I think polaris will have emigrated before it arrives, also frequently when I ask it to move either to a target or to home position it says that it cannot do it.?
Any help would be much appreciated

I recall seeing something about this issue.? From what I recall the Gemini-2 is set to Guide or Move during the PA process.? Check the slew speed on the HC and make sure its set correctly.? Sorry; I don't recall what the actual fix was.

Thank you for this input and I will certainly check the next clear night, however one extra point is everything works fine using the hand controller, it just breaks down using the asiair

the issue was that PA process uses center speed, which needs to be increased to 600 so it's not so slow

Barry,
To fix the speed issue on the PA, change the Move speed on the Hand Controller to 500 or more.? Once you get it PA'd, the goto should work fine, but if it doesn't let us know what message you are getting.? One thing on the goto, if you have put in safety limits on your mount and the goto would exceed those limits (say your target is at the meridian or close to zenith), the mount will not respond to the move command.? Regarding going to home after tracking or imaging, I have not figured out that issue as mine does the same thing and I have heard of others having issues.? ?It does try to go home and usually if I tell it to go home twice or after an imaging session it gets close. But as long as you have your safety limits set, I do care if it does go back to home after an imaging session.

Hope this helps, Jim
 

Sorry Jim has it correct. It's changing the move speed

Hi Barry,?

A few questions to help me keep track of this stuff.

What version Gemini are you using, all Gemini 1, Gemini 2 original tallboy or Gemini 2 mini???
What version Gemini 1/2 firmware does the hand controller show??
If using Level 6 Beta firmware what is the date of the L6 firmware and HC firmware??

What version ASIAIR app did you update your ASIAIR Pro to? The last production ASIAIR app release was v2.0 with 10.46 firmware. The current Beta from last week is ASIAIR app v2.1 with 10.71 firmware.?

One of the weirdnesses that happens with ASIAIR app and firmware updates is that the ASIAIR changes and/or forgets some Gemini settings. So it is not unusual for Gemini users to have to check the Gemini settings after doing a full ASIAIR app and ASIAIR firmware update. The one obvious issue is that the MOVE speed is always set to a very low value and you need to set it manually using the HC or web UI via browser. Also if using the L6 Beta you need to confirm that the servo encoder option is set to 4x not 1x.?

Thank you all for your help, I am using gemini 2 which has not been updated for a few years, it is not beta. The asiair app is also not beta and it is using the update issued approx 3 months ago

Hi Barry,

So you likely have the production level 5 firmware and similar HC firmware. It has been a while but AFAIK all you need to do is set the MOVE speed to 500 in the Gemini-2 or so using the web browser or HC and the PA routine will work fine.?

I also had the issue where the ASIAIR could not GO TO an object. I tracked it down to mismatched time and location data. Double check them and see if the issue changes.??

Barry,

The mismatched time and location data also includes epoch. I don't know which update to which device resolved the issue. But with L5 it was always a little bit off when using Gemini-2 to GOTO with the ASIAIR app. Your later ASIAIR app should work okay with L5 or at least well enough once it has plate solved for position. Then just sync between them.?

This doesn't preclude the importance of good polar alignment and building a model with at least two stars on either side of the meridian.? This is still important! As I understand it Gemini-2 must still have a good model for the ASIAIR to use or GOTOs will not be so good and potentially get worse as the number of GOTOs increases.?

Before I changed firmware to L6 Beta there was always a struggle between the ASIAIR and Gemini-2. The ASIAIR app always wanted to use my cell phone's data for time, date and location. I always wanted to set the time.to the correct UTC time and use zone 0 for offset as I have done for many years to avoid the twice a year issue of DST or Standard Time change and getting caught out by the change.

Also there is about a 19 second offset between GPS time which is what cell phones use and UTC which is adjusted in the real world with leap seconds. So GPS is ahead by about 19 seconds so they are always in conflict.?

In the end Igave up trying and just let the ASIAIR push its time and coordinates down to the Gemini-2. There is a button that is labeled refresh when you initialize the ASIAIR app. Use.it to synchronize the app with the Gemini-2 and let the app push the TDL data down to Gemini-2. IRL it matters little because the ASIAIR does a GOTO then centers using a plate solve to validate camera position against the actual sky.?

This is great help, thank you, I will change the setting as soon as we get a clear night?
