A.J.’s Mini Messier

Made using the .5m, Apogee CCD, and MaximDL software to

compile the images.

Project objects

• M1 (Crab Nebula)• M42 (Orion Nebula)• M65• M81• M82• M95• M105• M106

• 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 V-filter.

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 V-filter

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 V-filter.

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

• 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.

NGC3384 M105

NGC3379This was a 90sec exposure through the V-filter.

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.
