M99




M99
Constellation - Coma Berenices
Spiral galaxy
Distance 53mly
Mag 9.89

Date 24/4/14
Transparency - average
SQM 21.1 (LM6.1)

Telescope 16: f/4.5
EP 14mm Delos x135 (TFoV 0.32')

Sketch notes
The transparency improved for maybe 20 minutes which really helped seeing the spiral arms.
Although the sketch shows the arms looking very obvious at first sight M99 looked like a large fuzzy oval but with time spent two main arms were seen branching out to the NW and SE of the bright core.
