A.J.’s Mini Messier
Made using the .5m, Apogee
CCD, and MaximDL software to
compile the images.

• The project is split in both black and white
and a few composite pictures.
• The pictures will appear before the data
and then a smaller image will be included
with the data on the next slide.
M1 – The Crab Nebula
• This is a supernova
remnant. The super nova
was seen in 1054 CE.
• It is located in Taurus and
is about 6500 ly away
from earth. The nebulas
diameter is 11 ly and the
apparent magnitude is
+8.4
• This is a 120 second
exposure through the Vfilter.
M65 – Spiral Galaxy
• M65 is a Intermediate
spiral galaxy that is part
of the Leo triplet it is
however the only one that
I took in this set.
• It is about 22 million light
years away and has an
apparent magnitude of
+10.25.
• This is also a 180 second
exposure through the Vfilter
M81– Bode’s Galaxy
• M81 is a spiral galaxy
that’s approximately 11.8
million ly away.
• It was first discovered by
Johann Bode in 1774 and
it apparent magnitude is
+7.89. It and M82 (next)
are in the constellation
Ursa Major.
• This is a 20 second
exposure through the Vfilter.
M82 – Cigar Galaxy
• M82 is a starburst galaxy
that’s approximately 11.5
million ly away. A
starburst galaxy has an
exceptional rate of star
formation.
• The star formation is
increased due to its
proximity to M81.
• This was a exposure of
10 sec in the V-filter.
M95 – Barred Spiral
• M95 is a barred spiral
galaxy about 32.6 million
ly away in the
constellation Leo.
• Its apparent magnitude is
+11.4
• This was a 210 sec
exposure in the V-filter.
• Sorry about the dust ring
off to the side.
M105 – Elliptical Galaxy
NGC3384
M105
• M105 is an elliptical
galaxy that is about 32.0
million ly away.
• It is in the same group as
M95 (Previous) and M96
not photographed.
• In this exposure you can
see two other galaxies,
NGC3384 and NGC3379.
• NGC3384 is in the Leo
Group I and NGC3379 is
a more distant galaxy.
This was a 90sec exposure through the V-filter.
NGC3379
M106 – Spiral Galaxy
• M106 is a Spiral Galaxy
in the constellation Canes
Venatici.
• It is about 23.7 million ly
away and has an
apparent magnitude of
+9.1.
• It is also and example of
a Seyfert II galaxy, which
means that astronomer
suspect that part of the
galaxy is falling into a
super massive black hole.
This was a 180 sec exposure in the V-filter.
M1 – The Crab Nebula (Color)
• This is a color
composition of M1
• The exposure time
were
• 90 sec in R and I
• 180 in V
M42 – The Orion Nebula
• The Orion Nebula is an
example of an emission
nebula.
• It is about 1,270 ly away
but many source vary on
the exact distance.
• It has an apparent
magnitude of 3.0.
• This is only a 5 second
exposure through the V
filter.
M42(cont.)
• This is a a 10 second
exposure with the V-filter.
• The trapezium is not as
resolve as in the other
photo because of their
brightness and close
proximity (only 47 arc
seconds).
• This small cluster actually
has 8 star confirmed, but
the whole nebula has
about 2000 stars.
Trapezium
M42 (color)
• This two images were
each compiled using the
Maxim software.
• The blue was increase in
the bottom one and the
filters used were B,V,R,
and I. The R was use for
the luminosity because it
provided the greatest
contrast.
• The exposure time on all
the photos was 5 secs.
M42 – 3rd color
• This was a composition
that only use V,R,I and
the V exposure was 10
seconds and this was
also used for the
luminosity of the photo,
as well as the blue, R
was green and I was red.
• And of the three this is
my favorite. And is why I
chose to end with it.
