I've seen NGC 869/884 on and off, but tonight was my first log.

How can an observation be written for such a beautiful cluster?  So
I'll only concentrate on one interesting part.  NGC 869 and 884 both 
have pin-pricked stars at 30x and 60x.  But there are two interesting 
yellowish white stars of equal brightness in NCG 869 that looked like 
eyes: 6.6 mag SAO 23178 and 6.6 mag SAO 23182.  The eyes looked like 
they belong to a face hidden behind a veil.  Above SAO 23178, there 
is  a group of stars that forms a semi-circle that looked like an 
eyebrow (at 60x).   The eyebrow is very notable at 110x. The stars 
that made up the eyebrow are: 9.4 mag GSC 3694:1772, 8.1 mag GSC 
3694:3804, 8.6 mag GSC 3694:3807, and 9.3 mag GSC 3694:2324.  
However, I couldn't find the faintest star in the group between GSC 
3694:3807 and GSC 3694:2324 on my chart!  This missing star is hard 
to see as it winked in and out.  All 5 stars could be seen with 
winking one as noted.  146x and 220x showed great view, but 110x is 
best.  Last but not least, only a 2" eyepiece that give at least 3 
degree FOV can truly appreciate the majestic view of both clusters
