One of my astronomy goals is to see every Messier object. So far I have seen M45 (Pleaides) and M42 (Orion Nebula). These are two of the five brightest Messier objects. I am determined to see a Galaxy. Andromeda (M31) is the brightest galaxy and the second brighest Messier object after Pleaides. Unfortunately it is too low and behind the trees right now. My house is in a bit of a “tree well” with a relatively small set of patches where I can see the stars. This would be good if I were (more) paranoid because it would mean that the aliens would have trouble seeing me.
I tried for M81 (Bode’s Galaxy) and M82 (Cigar Galaxy), and M51 (Whirl Pool Galaxy). Unfortunately, I failed (I guess “No Cigar.”). I have tried for M81/M82 a couple of previous times. It is theoretically easy to find them from the big dipper. M51 should also be easy to find relative to the Big Dipper. Tonight, I decided to use the Orion Intelliscope Computerized Object Locator. I tied using it once before before but it was so cold that the LED would not work. I consider using it to be “cheating.” Part of the fun(?) is finding the objects the hard way.
Following the instructions was pretty easy. I got the telescope in the vertical position using a level. I needed to find two stars. Regulus was very close to Saturn and easy to find, in theory. Regulus seemed to be to the right and above Saturn to the naked eye, but was below in the finder scope. The finder scope image is not reversed. So, I was a little unsure if I was finding Regulus. The second alignment star was Mizar. This is easy to find, and I discussed it in a previous entry.
The locator displays a “Warp Factor” to tell you how accurate your calibration is. 0.5 is the target. I kept getting between 2 and 3.6. I found 2 acceptable. I tested the locator by finding Saturn, which I had previously found (needed to locate Regulus). Saturn was clearly centered in the finder scope and visible in the high power (1oMM Plossl). So, a Warp Factor of 2 seems good enough.
One of the Web guides to the Messier objects states “M81 is one of the easiest and most rewarding galaxies to observe for the amateur astronomer on the northern hemisphere, because with its total visual brightness of about 6.8 magnitudes it can be found with small instruments.” Well, not for me. I used the locator to point the telescope at M81. It pointed to a patch of sky that was completely dark in both the finder and 10MM Plossl. That is not an easy thing to do. There are stars almost everywhere. I also could not find M51. I used the finder to navigate to “points of light” near where M81/M82 should be, and near where M51 should be. No luck.
Conditions were pretty good tonight. So, I do not know what went wrong. The conditions were so good that I could see the gap between the rings and Saturn, and one of the divisions in the rings (perhaps the Cassini Division). Titan was clearly visible. I also saw two other moons, probably Dione and Rhea. The glimpse of the smaller moons was brief and slight atmospheric shimmer returned. The previous night, my girlfriend said that she could see a couple of smaller moons. I thought she was “mistaken.” I guess she wasn’t. Man, I am wrong even about Solar System. I hope she doesn’t find out.
I need to get knee pads. Moving around on the deck is pretty painful, especially when I kneel on a small stone.
My youngest daughter looked through the telescope last night; my oldest daughter could care less. She saw Saturn, and then said “Daddy, I see a star next to it.” I asked a couple of questions like “To the left or right? Above the rings or below?” She saw Titan.
She bought a “Shining Star” doll a few weeks ago. You get a star with the doll. She got one of the stars in the Big Dipper. I showed it to her, and think she managed to see it. I am not sure.
She wanted to look at the Moon. I told her that it was pretty low in the sky and we might not be able to see it. Her response was, ‘Don’t worry daddy. If you cannot find the moon, I will show you where it is.” She’s five; I thought it was pretty funny.
I looked at the Moon briefly tonight. I plan to start trying to identify features. I found three craters near each other forming a “snow man” with gaps between the balls. I think the biggest one might have been Petavius.
Last night, I could see slightly better through my left eye than my right. I use “mono vision” with my contacts, with one eye for reading and one for distance. The left eye is the reading eye, which explains why I could see better. I put the reading presciption in both eyes tonight and it helped.
