amateur observing - SDSS. Google Sky and DeCaLs

The Sloan Digital Sky Survey has saturation limits at around 13th or 14th magnitude. You are looking at $phi$ 1 Cancri, which is a 6th magnitude star. It is hardly surprising that SDSS fails to morphologically classify it correctly.



No idea what your second question is about. You have given a link which has a latitude and longitude in the url. Longitude and latitude are not valid ways of expressing the coordinates of a celestial object. When I open this link, I see an image of your star and in the bottom left of the screen there is a display which gives the RA and Dec of where the cursor is.
