Hello,
many other programs allow simple online queries for GOTO.
SIMBAD identifier query would be nice.
IMHO it is not much effort to ask SIMBAD for RA/DEC of given identifier ?

Re: GOTO (Online) Catalog Target ?
Hi Thomas,
nice idea - I just looked and queries by ID are really simple
https://simbad.cds.unistra.fr/simbad/si ... &Ident=m31
I wonder if there is a similar lookup for things like comets and asteroids that have varying position...
cheers,
Robin

Hi Robin,
https://www.minorplanetcenter.net/iau/M ... ation.html
but you have to calculate the current position yourself. But I'm not that much of an expert, maybe there is such a thing.
But querying fixed objects would really be a great help. Even there you still have the position change J2000 ->JNow and possibly the Proper Motion. However, this may not be so important for photos, as long as the object is in the picture, which is more of a problem with precise annotations.

I am not aware of anything like this, you can certainly download the current orbit data, e.g. from the MPCI wonder if there is a similar lookup for things like comets and asteroids that have varying position...

Re: GOTO (Online) Catalog Target ?
Hi,
yes, grabbing the orbital elements and calculating was my second choice of how to do it for small bodies - hopefully there is some existing library out there that I can use for the calculations as it is easy to make mistakes when converting these sorts of calculations into code.
cheers,
Robin

Re: GOTO (Online) Catalog Target ?
Hi,
that looks like it would do the job in Python, but SharpCap is largely C# - I'm hoping that there is support for this calculation in the AASharp library. There should be as it covers most of the classic 'Astronomical Algorithms' text by Jean Meuss, but often it's a case of being hard to find the right bit of functionality unless you already know exactly what you are looking for...
cheers,
Robin

Hello,
it would be very nice to have in a first step just a simple SIMBAD ID query.
Also in Sequencer, interactive query step like now for internal SC object catalogues.
