thank you for your suggestions. We will consider adding the data you propose.
Regarding the rest of items, I am not sure that you are aware that you can change the coordinate frame from equatorial J2000 to galactic with the drop-down menu on the top left corner. In doing so, the coordinates indicated on the top bar change to galactic, the Galactic plane automatically gets horizontal (you can check this by zooming out to a large field-of-view), and the grid is displayed in galactic coordinates.
Please note that if you are using the galactic coordinate frame, all coordinates you enter, either in the search box on the top right or in a target list, will be interpreted as galactic. You will get an error if the coordinates are given in sexagesimal format, as this is not used with galactic coordinates. Also, in the case of target lists, the coordinates are read once, so if you later change to J2000, still they will be interpreted as galactic.

thank you very much for your suggestion. As you may have noticed, we have recently released ESASky 3.2 with a new functionality to query external data servers. Currently only ESO, CADC and MAST are available, but we plan to include more in the future, and of course we would like that IRSA is one of them. So stay tuned!
thanks for spotting this! One of our engineers had forgotten to commit the last update. It should be ok now.
sorry for not having replied to this before. This functionality has long been available in ESASky.
more recently, we developed pyESASky, which allows you not simply to query, but also to use most ESASky functionalities and even to upload your own datasets. More information here:
This is now possible thanks to the slider implemented in version 3.2
For the records, this functionality has finally been implemented in version 3.2!
sorry for having left your post unreplied. As Deborah explained, the all-sky maps available right now are just RGB representations of the data from given telescopes/surveys, created by combining different filters. You can find more information about how the colours have been assigned to the different wavelengths/frequencies/energies in our documentation. These maps are intended for quick visualisation and not to do science. However, we are working on a way to improve this visualisation, so that users can, for example, play with the image cuts. We hope to have more news on this in the near future.
Regarding your second suggestion, about the colour maps designed to accommodate colour-blind people, you may have noticed that our treemaps (which pop up when you click on the buttons to search for data) are now colour-blind friendly.
we now have a python module that allows you to use ESASky in a Jupyter Notebook. You can work with the capabilities of ESASky and also upload your own data to the application. Go here for more information:
since version 3.2, you can overlay a coordinate grid on the field of view. It is also possible to take a screenshot with all the overlays. While this is still not what you are asking for, we hope you find it useful. We will keep working toward implementing your suggestion.
Please note also that the size of the FoV is now provided as RAxDEC.
