Note:
Seeing 6 out of 10. Recent cold front pretty much trashed the good
seeing that had previously experienced... at least for a few days with
the big scopes. So to have some fun! Pulled out the trusty 4-inch
planetary scope; my original Mars scope, built for the 1986 Opposition.
A half dozen oppositions later and dozens of great observing sessions
with this little scope and this had to rank up as one of the best. 25
arcseconds for the 4-inch, and tons of detail.
For the first time, I was
able to comfortably use w25 (red) and w47 (blue) filters. Mars looked
quite clear with little happening other than some North Polar Hood
action. Very nice detail in the Mare Erythraeum area. This area was
nicely framed by Solis Lacus (following) and Sinus Meridiani (P).
Niliacus Lacus, north of ME, was quite dark and very apparent, perhaps
the darkest northern feature of this opposition.
