Manual sync

#1

Post by astrocalina »

Hello,
I've question but I don't know if is it possibile (and if yes how to do it):
  • I take a FITS file with i.e 4s exposure
    I solve the fits with nova.astrometry.net
    I copy the coordinates solved by astrometry.net
    I want to sync manually my telescope with the copied coordinantes
Is it possibile to do that (maybe with a script or something)?

Hi,

yes, you can do that through the sequence editor - the steps you would need are

* Set the target to (RA,Dec) <==== this will need your co-ordinates
* Sync mount to target co-ordinates

Note that you will need a very up-to-date version of SharpCap 4.1 to see these particular steps as they were only added late last year.

cheers,

Robin

Hello,

If you can change the Plate Solve from astrometry.net to the intern SharpSolve of SharpCap (or ASTAP),
then you can do the telescope synchronisation without additional steps directly after a plate solve action.

I recommend the SharpSolve ... it is very quick and work very good. But it is limited to 0.25°x 0.25°sky index.
Depending of your resulting focal, maybe you will need to stay with astrometry.net.
The other advantage of the SharpSolve is ... you are offline.

Thank you for your answer Jean-Francois,
I want to use Astrometry too when ASTAP fails or to be sure that everything is working fine.
The biggest problem is that my FOV is only 0.26 and not always it will sync so I will try using astrometry.net on manual mode.

Hi,

this text saved as an .SCS file will have the required result - you would need to edit the co-ordinates as I have just put in sample ones

Code: Select all

SEQUENCE
    MOUNT SET TARGET TO "RA=10 23 45 Dec=67 78 89"
    MOUNT SYNC TO TARGET
END SEQUENCE
Note that you can use decimal RA/Dec as well as Degrees/Minutes/Seconds

cheers,

Robin
