I have a couple of questions regarding the new features of the Explore Star App (Android):

1)      New button to display objects near where the telescope is pointed (OBS button)

Question:  Does this mean, when you are doing a star alignment and you hit the OBS button, the app will organize the available stars you are able to see in that specific area automatically?

 

Where the FOV is set in Settings:

Question:  Is the FOV button in settings depicted as “Obs Size”? The app’s default is 2…so is that a FOV of 2-degrees?

 


3) Improvement in the Alignment Routine operation.

      Question:  Does this take into consideration the elevation at a given location? 


7) The button used during alignment was changed from SYNC to ENTER to more accurately describe the function during the alignment process. When pressing ENTER during the alignment process, the data is being gathered for 2 or 3 stars and then after the final data is acquired, the mount model calculation is performed and the alignment is completed.

 

The SYNC button now only does as it is defined, see time 3 below. The SYNC is also known as a 1-star alignment and is used when you have a good to excellent physical polar alignment typically needed when doing astrophotography.

 

A few bugs were identified and corrected in combination with the firmware update:
3) The SYNC button functionality now works as designed, setting the current mount position to the target coordinates when pressed.

        Statement:  “Sync” is now 1-star alignment.  Why not replace the word “Sync” with “1SA”  (one-star alignment) in the settings/ main screen menus? 

 

Thank you in advance for your assistance regarding this matter.

Hi JR, 

Thank you for your questions.  I will try and answer them in order

 

1)      New button to display objects near where the telescope is pointed (OBS button)

Question:  Does this mean, when you are doing a star alignment and you hit the OBS button, the app will organize the available stars you are able to see in that specific area automatically?
The OBS button shows a list of the objects in the database that are within the set number of degrees, i.e. 2 degrees when set to 2 (See next question). I wouldn't say that it "organizes" it literally just lists them so that you can see what other interesting objects you might be looking for are near where you are pointed. This is really meant for when you are observing, not necessarily when doing an alignment

 

Where the FOV is set in Settings:

Question:  Is the FOV button in settings depicted as “Obs Size”? The app’s default is 2…so is that a FOV of 2-degrees?
Yes, the "Obs Size:" field on the Settings page is used ot set the FOV, 2.0 means 2-degrees as you say.

 


3) Improvement in the Alignment Routine operation.

      Question:  Does this take into consideration the elevation at a given location? 
I am not sure what you mean. If you are talking about what stars are available and are shown in the list, it only is concerned with showing everything above the local horizon. It assumes a perfectly flat horizon with no obstructions such as houses or trees. The elevation has no impact on which stars would be above an unobstructed horizon.


7) The button used during alignment was changed from SYNC to ENTER to more accurately describe the function during the alignment process. When pressing ENTER during the alignment process, the data is being gathered for 2 or 3 stars and then after the final data is acquired, the mount model calculation is performed and the alignment is completed.

 

The SYNC button now only does as it is defined, see time 3 below. The SYNC is also known as a 1-star alignment and is used when you have a good to excellent physical polar alignment typically needed when doing astrophotography.

The definition for setting the current motor counts to the current coordinates is "SYNC" this is what the function does. Calling it a 1-star alignment may be a simple way of looking at the function, but is a misnomer and shouldn't be used as it confusing. It is confusing because the SYNC function does not impact the alignment model as you might assume it might when using the term "1-star alignment" would. The SYNC does not have anything to do with the alignment just as when you set a clock to the proper time does not impact how much time is between the numbers 3 and 4, it's always 5 minutes between minute hand positions 3 and 4.
 

Thank you in advance for your assistance regarding this matter.

No problem, thanks for your questions.
