14-2-11 7:45-8:20PM OBSERVATION (Constellation of Andromeda/Andromeda Galaxy [M31]) [OBS #5]

Today I braved the elements again and got in another observation. This time I went a little west of Cassiopeia and looked at Andromeda and the Andromeda Galaxy/M31.

Again, I had focus issues with my camera.  I think what happened was a combination of star drift and too wide an aperture.  I was using my 50mm lens, and I noticed that I had stuff out of focus at 1.8, but when I moved my aperture to 3.5, it improved.  I was able to get a picture that wasn’t too incredibly horrible out of about 20 shots.  In this one, the Andromeda Galaxy is somewhat present.

Here is the image with a little more of a guide to what you kinda sorta are seeing:

That smudgy thing in the circle is the Andromeda Galaxy.  It is around the size of the moon, about 2° in size.  It is noteworthy that Mirach (β Andromeda) is a red giant.  By naked eye this could not be seen, but it could be seen in the above photo.

Here are some clearer views in Stellarium.

I also spent some time fiddling with a multi reticle red dot finder that I purchased which goes on top of the 25x100s.  Got it to work by zeroing in on the moon.  It does make finding things easier, assuming I can star hop to where they are.  With binoculars, though, compared to telescopes which are inverted and/or upside down, it is far easier.  the Finder can also double as a rifle sight (yet another hobby of mine).

While what’s below isn’t my actual red dot finder in action (it was a bugger trying to take a picture of it due to depth of field issues), this is essentially what it would look like looking through it.

Here is my observation report for tonight:

Sadly, due to shifting transparency conditions, I was not able to see the Andromeda Galaxy using the 25x100s tonight, although I was able to see it with my 8x30s earlier in the evening.

Per Wikipedia:

Here is info on Andromeda, the constellation.

Andromeda is named after the daughter of Cassiopeia.  Andromeda was apparently chained to a rock to be eaten by the monster Cetus, which is behind Pisces.  It is bordered above by Perseus, below by Pegasus, to the right by Andromeda’s mother, Cassiopeia, and the Pleiades are to the left.  Pisces and the Triangulum are to the left, but closer.  Only one or two stars in Pisces were visible tonight, and Pegasus was behind trees.

Perseus figures as the savior of Andromeda from Cetus (See this part of the Perseus myth).

Here is info on the Andromeda Galaxy/M31.

The Andromeda Galaxy/Messier 31 is one of the largest deep space objects of the Messier group.  It is a spiral galaxy about 2.5 million light years away from Earth.  It will collide with the Milky Way galaxy in the future!  In 3.75 billion years.  Not high on my list of anxieties this week.

Here is an interesting video on the Andromeda Galaxy:  Video on Andromeda Galaxy from NASA (public domain)

I hope to do another observation of the Andromeda Galaxy in the future, when transparency conditions are better.
