• 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.

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.

• 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.

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.
