			 Poor alignment betweeen HST outreach and Gaia FPR
		
		
	
              
            
            
            Poor alignment betweeen HST outreach and Gaia FPR
        
    
    
    
    
    
    
    
	I have noticed poor alignment between the Gaia Focus Product Release catalogue of Omega Cen and the HST Outreach image in the same region. Can this be fixed?

 
        
            
            
	
		
		
		
			 "Publications" not working/Sat shadows in ESAsky
		
		
	
              
            
            
            "Publications" not working/Sat shadows in ESAsky
        
    
    
    
    
    
    
    
	Today I can't seem to get the "Publications" result to yield anything. Its hung up in an endless loading cycle. I've cleared cookies, caches, switched browsers. There also appear to be some strange shadows and tinting that look to be being caused by externals on a satellite.
GALJ2000GALJG223.5904988 -08.6562613FoV: 9.6° X 4.8°DSS2 color ; is one such example.

	If just browsing the sky, I have found some interesting looking objects but cannot see an easy way to identify them within EsaSky

            Milliquas
        
    
    
    
    
    
    
    
	I have not yet found the display function in ESA Sky which allows us to display known and imaged Quasars, AGN and Candidates.
From the 1.5 Million or so in our database to date. Viz the Million Quasars (Milliquas) catalog, v7.10, 15 April 2023
https://quasars.org/milliquas.htm
How do we toggle/display all known, imaged, Quasars for viewing and exploring in ESA Sky?
Or Open Clusters, Globular Clusters, Dwarf Galaxies, Galaxies, etc.?
Thank you. I was not able to get any assistance from the SDSS for viewing the imaged Quasars in the Catalog

            Search for more than one object
        
    
    
    
    
    
    
    
	Hi,
I use ESASky to prepare my observations in telescopes, and it would be really good to have the option to search for more than one object, for instance to measure the angular distance between both of them.
Thanks,
Nuria
 
        
            
            
	
		
		
		
			 define overlays (e.g. cone search regions) via URL parameters
		
		
	
              
            
            
            define overlays (e.g. cone search regions) via URL parameters
        
    
    
    
    
    
    
    
	Hi,
it would be great if you could add optional paramters to the URL that allow to define sky regions around the central position. This would allow to load ESASky centered on a position (e.g. the best fit location of a new, possibly transient, source) AND show the uncertainty of this best fit position. This is exremely helpful to find possible MWL counterparts to the new source.
In Aladin Lite this feature is available via the use of overlays directly in the URL. An example (defining a circular region of radius 1.5deg):
https://aladin.cds.unistra.fr/AladinLite/?overlays=[{ "type": "graphic", "name": "uncertainty", "color": "darkgrey", "lineWidth": 4, "items": [ { "type": "circle", "ra": 288.4037, "dec": 0.3537, "radius": 1.5 } ]}]&target=19 13 36.89+0 21 13.32&fov=63.4675
Thanks a lot for your great work on ESASky!

			 Gaia Proper Motion display formats
		
		
	
              
            
            
            Gaia Proper Motion display formats
        
    
    
    
    
    
    
    
	The format of Gaia DR3 columns has changed recently as shown in the attached screenshot so that, for example, "Proper Motion in RA" is shown in the HH MM SS format usual for RA proper. This doesn't make much sense and I don't think it's me. The same applies to "Proper Motion in Dec" and both their errors.

            Source error regions
        
    
    
    
    
    
    
    
	It would be very useful at least to have an option to plot catalogue sources with symbols the size of the error region (or source extent) . For instance, when comparing XMM and Chandra source lists of the same region, this would give a good idea of how well they agree.
