Description:
55x- The Trifid nebula is bright enough to make the dark lanes stand
out strongly. The nebula fades away towared the outer edges, but
remains bright enough to be defined. There are 2 brighter stars at the
north, the bright tight cluster of brightest stars are near the center.
138X- The O-III filter while dimming the view overall really increases the
contrast between the nebular material and the dark lanes. There is an Island
of nebula at the intersection of the 3-lanes. The Tight cluster of stars that
are the bright exciting source for the nebula lay near the tip of the peninsula
at the north east side of the southern most north-south lane. With 314x the
bright grouping appears to have 3 stars in a tight row oriented ne-sw. There
may be a 4th star in the lineup, but I can't be sure. Along the eastern edge
of the island are 2 or more small dark lanes penitrating a short distance.
There are lots of foreground stars superimposed on the nebula. A fairly large
guite faint glowing area lies to the NW of the Trifid proper. A grand sight
in any scope under dark skies.
