Eta Carina detail JWST custom nebula query

[Martin Lewicki]

I read the section Chapter 8.2 pages 103+ on Adding Eta Nebula Images. Need assistance as the nebula does not show up.

I chose this  famous detail from the JWST of Eta Carina. But after adding the nebula to the textures.json file and the  image to the nebula directory it would not appear. I use this image.

https://planetary.s3.amazonaws.com b/assets/pictures/jwst-carina-nebula.jpg

I reduced the size to 884x512

Amazingly I found the exact Ra-Dec corner coordinates (or nearly) of this  image in the World Wide Telescope app. One finds Eta Carina then zooms in until the eponymous image is visible and the corner coordinates can then be determined!

Maybe in Stellarium the small JWST detail image ends up covered by the  larger default superimposed image of Eta Carina Nebula itself, that is, it is a layer problem.

Here is the added entry at the end of the textures.json file. I include a portion of the previous entry so one can check if there are any syntax errors in the flow.
