sorted a fuzzy

Noticed it before, but today, on deep-diving into the SA 104 image, I looked closely again at the area around the star J124345.2-002116. To me it looked like there was a fuzzy.

Tried plate-solving the image on (link).

It did not go very deep. Ah. What's that green line? The constellation line?!

Tried Aladin Lite, the online (limited) tool. When I switched to SDSS9 mode, it popped (link).

My immediate impression was that there were old elliptical galaxies here...

Went into Simbad and punched up the location (link). Interesting: two objects noted within a 2 arcmin area.

The first was a G class star at mag 15.6. But the second one... Very interesting. Much further away, curious name, curious type... When I clicked the link, I landed at a page describing a Seyfert 1 Galaxy. Ah ha.

Took a quick look at the Astrometrica web site but couldn't tell if it might work. Didn't feel like downloading more software... Wanted more info so I turned to Greg.

He did some digging and shared a screen snapshot. He said it was LEDA 3111069, Hubble type E, nearly face on.

I looked it up in HyperLeda. Confirmed.
