    vary faint bared spiral, not an elliptical?

    It's certainly not a boring elliptical, that's for sure ... ellipticals have no structure, in images like SDSS and DECaLS, just a central brightness which fades slowly and steadily as you go away from that center (the nucleus)^, even the color hardly varies from center to edge.

    So, yes, a sprial, and a barred one to boot (I reckon).

    Hope this helps, and happy hunting! 😃

    ^some caveats: some galaxies that look exactly like ellipticals have dust lanes, and some have bright, star-like nuclei; however, none have bars, arms, rings, ...
