Anyone notice in that C/2022 E3 (ZTF) is within a wide-field of view's grasp of dimmer, 11th mag comet, C/2022 U2 (ATLAS)?

 

At least according to CdC tonight and for a little while! 

 

Wish me luck!

 

Here's my 200mm DSLR views a few weeks back.

Yep.

Disappointingly it's listed as Mag16

Skysafari has C/2022 U2 (ATLAS) at 16.2 mag.

[Carl H.]

C/2022 U2 (ATLAS) is much brighter than the prediction currently produced by the Minor Planet Center.

 

The comet should be around 10.0. Recent images show it to be a nice round fuzzball with just the slightest hint of a tail.

For sure I can hit mag10 in my 200mm Canon60Da setup!  Wish me luck with that pesky moon nearby.
