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.
