M53 (GC)

../dss/dss2blue_131255.25_+181005.40_15_web.jpg
Image source: DSS II (blue) - 15×15'
Name: M53, NGC5024
Type: GC
Constellation: Com
Coordinates: 13h12m55.25s / +18°10'05.40"
Brightness / Size: 7.8 mag / 14.4x14.4'
B 40mm, 8x, NELM 4.3+
Relatively small, slight brightening toward the middle.

MODERATE
102mm f/11, 86x, Bortle 6, SQM-L 19.2
At 86x very bright, well condensed. Indirectly, the peripheral parts are clearly granular. Glimpsed few individual stars with averted vision. At 160x the cluster appears granular close to the very compact center. There are several individual stars visible with averted vision, especially in the peripheral parts.

EASY
4.5" f/8, 28x, NELM 5.0
Moon (60% illuminated): Despite the rather low altitude of about 35° above the horizon the globular cluster was easily visible at 28x and very evident. It appeared round with much brighter center. Not resolvable.

EASY
120mm f/5, 85x, Bortle 4, SQM-L 21.3
Obviously granulous. Individual stars visible in the edge regions.

EASY
8" f/6, 37x, Bortle 4-, NELM 5.8+, SQM-L 21.0
SQM-L 20.7: Very bright, extended and relatively sharply defined center. Outer regions much more fainter. At 150x the outer regions were resolved, the center was more granulous.

NGC4147 (GC)

../dss/dss2blue_121006.15_+183231.78_5_web.jpg
Image source: DSS II (blue) - 5×5'
Name: NGC4147, NGC4153, H1.19
Type: GC
Constellation: Com
Coordinates: 12h10m06.15s / +18°32'31.78"
Brightness / Size: 10.3 mag / 4.0x4.0'
80mm f/6.25, 41x, Bortle 7, NELM 5.0, SQM-L 19.3
At 25x quite compact brightening. At 41x round, slight brightening toward the middle.

MODERATE
8" f/6, 37x, Bortle 4, SQM-L 21.0
SQM-L 20.7: Round, relatively compact brightening. Still visible with direct vision.

NGC5053 (GC)

../dss/dss2blue_131627.09_+174200.90_15_web.jpg
Image source: DSS II (blue) - 15×15'
Name: NGC5053, H6.7
Type: GC
Constellation: Com
Coordinates: 13h16m27.09s / +17°42'00.90"
Brightness / Size: 10.0 mag / 8.9x8.9'
120mm f/5, 48x, Bortle 4, SQM-L 21.3
Faint, pretty large, evenly bright, diffuse.

MODERATE
8" f/6, 37x, Bortle 4-, NELM 5.8+, SQM-L 21.0
SQM-L 20.7: At 37x fairly large, faint, nearly evenly bright. At 150x few stars visible with averted vision.
