This is where having the "head" helps -- it is a truly dark starless intrusion into IC 434 that makes it in turn easier to see IC 434.
The other problem is that there are no filters that are of any practical use because it is a reflection nebula.
I'd be more than happy to accept correction but I doubt it could be seen in less than 30cm, more likely 40cm.
Best,

Looks like we have a nice challenge here. First one to spot it gets bragging rights
