    there are three write-ups on this heading because the write-ups that I did kept disappearing like they did not register ,when I went to my profile they had registered / not sure what happened . Ian

    This is a star (maybe even YSO). There is probably also some contamination by background objects and interstellar dust as you can see in WISE images

    No problem Ian. It's very easy. Just open VizieR, then insert coordinates, choose radius and click on "go!" button.

    Then just scroll down until you find these results and click on those image links.

    Just keep in mind that WISE images are available for all DD objects, but SDSS images just for some of them.

    There is a clear contamination at WISE 3-4.

    This SED is strange actually. There is a missmatch between the 2MASS and the WISE data. Is it really from a WISE 1-2 excess and a circumstellar disk?

    Is there any kind of follow up for these embedded sources?

    HI anoxie , And having had a second look ,I see multiples in DSS Blue and up to 2MASS K .
