I found it through the VLASS tab then saw there was a optical counterpart. I have been trying to build up an intuition for what different spectrums look like for different objects. This one seems bright, according to simbad it has a redshift of z = 1.25
Wow thank you, but I would like to know how to find these on my own. It is not as intuitive as the sdss one I use. Is there a way to search directly without knowing the target id?
I guess some targets have multiple IDs, a new ID for every survey.
No such targetid found in DESI DR1 spectra: 39626881594560513
No such targetid found in DESI DR1 spectra: 35184854618341715
These are the same target ESO 306-17

In the “DESI” menu, the “DESI DR1 spectra” is what you want - that has direct links to the spectra.
In the screenshot above, you’ve got the “targets” turned on - those are all objects we would like to observe.
Okay so EOS 306-17 does not have a spectra in that manu probably because it doesn’t fit the criteria for that survey.
Yes, at Dec=-40 it’s not really reachable from the northern hemisphere where DESI is.
Gotcha, that’s at kit peak Arizona. So the Blanco 4m telescope in the southern hemisphere does not have the fiber-optic instrument yet to separate the spectra cleanly. I am guessing there is a discussion for that in the future.
Right, the Blanco telescope at Cerro Tololo in Chile has the Dark Energy Cam (DECam), an imager, responsible for most of the Legacy Surveys imaging in the viewer. The Mayall telescope at Kitt Peak in Arizona has the Dark Energy Spectroscopic Instrument (DESI), a 5000-fiber-fed spectrograph.
There’s definitely a lot of thinking about how best to use DECam in the future, since the Vera Rubin Observatory is on the next mountain over. People in the DESI project are hoping to use a large number of DECam nights to do medium-band imaging for DESI-2, but that definitely has not been decided yet.
