Oh boy. 11.9 is pretty dim. That would be a nice hat trick to get two in one. I looked at it on the sky tools chart and you are right. Pretty close. I doubt we could do it visually as 11.9 would require a big scope and a dark sky. We did see the one in Cassiopeia few weeks back at 10 something in Kent's 16 inch. I was not sure we could do that but we did. The 25 inch would be a good tool but with 25 inches comes tighter fields. A visual challenge, I would not place much money on doing but if you can do an image that would be neat.

I was looking at my sky charts for the upcoming week and noticed that both C/2022 E3 (ZTF) and C/2022 U2 (ATLAS) were only about 44 minutes apart on the 6th of February at 7:27pm EST. May try and get a pic if the weather holds. C/2022 U2 is only listed at 11.9 so pretty dim.
