I've obviously observed this beautiful galaxy many times, but systematic logging has not been my forté. The first sketch I have is from Coorg in south India with my former Discovery 17.5" f/5 -- however, this sketch was not done on the field but reconstructed from memory of the eyepiece view while referencing a photograph, so it might not be an accurate reflection of the observation:

Then I have two logs on the venerable 48" -- I think one of it might be the same night as Howard's beautiful sketch:

This is from 2014-10-25:

NGC 891 and MAC 0222+4222 [2016-10-04]:
Wow! Lots of detail, wide dark lane! MAC galaxy is averted only but
nevertheless not too difficult to see.

Thanks to this OOTW, I just added the two 2MASS galaxies to my observing list, especially after being encouraged by Uwe's report of seeing one of them in a 16". Hopefully, I'll get a chance to give this a shot with my 18" some time in the future. (For now, sheltering in place hard).
