M-65:  Dimensions - 10' x 3'.3 - mag. 9.3.  Messier 65 is bright in 6 cm=2C=
 a very elongated and concentrated nebula.  Low powers show a stellar nucle=
us.  It appears fainter than M-66.  The N side of M-65 the halo seems quite=
 knotted=2C the core is granular.  A mag. 12 star is visible 2' SW=3B a fai=
nter star lies about the same distance NE of center.  In 30 cm it shows a s=
trong=2C even concentration toward a mottled inner regions and a distinct n=
on-stellar nucleus.  Passing E of the nucleus is a dark lane=2C making the =
E side of the nebula generally fainter.  Lying 30" E of center in the dark =
lane is a threshold magnitude star (This will prove to be very difficult - =
Roger Ivester).
M-66:  Dimensions - 8'.7 x 4'.4 - mag. 9.0.  Messier 66 is a large=2C lenti=
cular object in 6 cm=2C located at the SE end of a crooked string of three =
mag. 9 stars.  The surface is irregularly concentrated and without a promin=
ent nucleus.  15 cm shows a large bright object with a bright concentrated =
core.  (The chain of stars are easy in my 4-inch refractor - Roger Ivester)=
.  In 30 cm the NE side is particularly mottled.  The core which brightens =
evenly to a non-stellar nucleus is chopped-off on its NE and SW sides by da=
rk blotches (Difficult - Roger Ivester).
NGC-3628:  Dimensions - 15' x 3'.6 - mag. 9.4.  This long galaxy is bright =
in 25 cm.  The halo extends to 10' x 1'=2C elongated E-W=3B it extends more=
 W than E from the center (Can easily see on my sketch using my 10-inch ref=
lector - Roger Ivester).  In 30 cm the elongated core is crowded against th=
e N flank of the halo and contains a faint nucleus.
