TargetPrima and Secunda Giedi, α 1 Cap and α 2 Cap, or Algedi
Time5Oct04; 2043 EDT
CategoryDouble Stars
CommentsThis is a double star at the western end of Capricornus that I can just make out naked eye. These stars are the brightest stars in the constellation.
[α 1 Cap is a double at magnitudes 3.2 and 4.2
&alpha 2Cap is a tripe at magnitudes 3, 11.5 and 11.5.]

TargetM31, Andromeda Galaxy
Time5Oct04; 2116 EDT
CategoryDeep Space Objects
CommentsI wanted to find it tonight on my own to fix the hop in my memory but had trouble tonight. It wasn't as bright as it had been on Sunday night, but I was looking in the wrong place too. The stars of And are not as widely spaced as I remembered them so I was looking too close to Cas. When I stared directly at it it disappeared the way the Blinking Nebula does for others. It was much easier to see and looked denser when the binoculars were in motion. After Peter called my attention to it an elongation along to 8:00 - 2:00 axis was obvious in his scope.

TargetNGC457, Owl Cluster, ET Cluster
Time5Oct04; 2249 EDT
CategoryDeep Space Objects
CommentsIn Peter's scope at 90x tiny stars are visible running through the chest of the owl/alien - a heart. A very rich field of view.

TargetNGC7789
Time5Oct04; 2307
CategoryDeep Space Objects
CommentsThis is an binocular open cluster off of β Cas. I have tried for it before but never had any luck so our skies must be getting darker. It is a dim collection of stars between a triangle of brighter stars and a pair of brighter stars of unequal brightness about three degrees distant. There is an arc of stars connecting these two sets of jumping off stars. From that arc of stars there is another arc extending at right angles in the space between the jumping off groups and this is what I am interpreting as the cluster.

TargetM31 & M32
Time5Oct04; 2314 EDT
CategoryDeep Space objects
CommentsObserved at 90x in Peter's scope.
M31, Andromeda Galaxy: was huge and very bright
M32: is only about 1/4 the size of M31 and much dimmer. I did not see it in my binoculars.

TargetMeteor
Time5Oct04; 2318 EDT
CategoryMeteors
CommentsA bright meteor with a tail streaked across about 30 degrees of my field of vision coming from behind me in the south and fading in Per. Peter saw it before it faded and thought he saw it break up into two smaller areas of light. I remember it as being faint yellow/orangish. It was probably a sporadic as it did not come form the direction of any of the active radiants.

TargetNGC752
Time5Oct04; 2325 EDT
CategoryDeep Space Objects
CommentsAn open cluster in And. Huge and full of dim stars. It took up half of the field of view in my binoculars.
[50', mag 5.7]

Targetν Draconis
Time6Oct04; 0003 EDT
CategoryDouble Stars
CommentsA moderately wide double in the head of Draco, the dragon. The two stars are about equal in brightness and similar in color, white.

TargetLyra
Time6Oct04; 0009 EDT
CategoryDouble Stars
Commentsε Lyra: wide and equal in brightness; white in color
ζ Lyra: close and unequal in brightness; the dimmer star may be yellow, the brighter white
δ Lyra: wide and unequal in brightness; the bright star is yellow and the dim one is blue

TargetNGC6543, Cats Eye
Time6Oct04; 0015 EDT
CategoryDeep Space Objects
CommentsA planetary nebula. It appeared in Peter's scope as a large blue ball, but not as blue as the Blue Snowball.
[18", mag 8.1]

Targetβ Cyg
Time6Oct04; 0021 EDT
CategoryDouble Stars
CommentsA close double of very unequal brightness. The brighter star is golden and the dimmer blue-white.

TargetM71, NGC8938
Time6Oct04; 0038
CategoryDeep Space Objects
CommentsThis globular cluster lies along the shaft of the arrow of Sge. In my binoculars it appeared to be a star.

TargetMoon

CategoryMoon
CommentsMare Imbrium:
- Plato is very light tonight, about the same shade as Mare Imbrium.
- Archimedes is showing a very white rim
- Montes Alps and Montes Apenninus coming off the terminator show good relief
- Eratosthenes crater (named after Ερατοσθένης, Eratosthenes, the Greek mathematician, geographer and astronomer who calculated the circumference of the Earth using triginometry in 240 BC) appears to be a deep crater with a small crescent of shadow on the sun side of its floor. It is at the end of Montes Apenninus.

Not much ray structure evident tonight - very little off Tycho and a little from Copernicus.

The terminator is passing through a very rugged area in the south just to the right of Tycho.

TargetCyclops Asterism
Time6Oct04; 0112 EDT
CategoryAsterisms
Commentsθ Tau could be split naked eye again tonight.

It is later in the evening and Tau is higher in the sky and it is a clearer night than Sunday was, so there are more stars visible in the Cyclops tonight. Now there is a wide double at the base on his right near his feet. This must be the eyes of his dog. He is standing on his feet tonight and occupies most of my field of view.

This is my personal record of my astronomical observations. It was written for my personal reference. The only reason it is in a blog is that a blog is a very convenient way to get the records formatted more or less uniformly and they will, hopefully, have greater longevity at Google where the servers are backed up than on my hard drive which never gets backed up. I occasionally include copyrighted material in my posts. I do this to make it convenient for me to access things I think I might want to refer to again. I think of this like making a photocopy of something I read that I put in a file where I can find it when I want it.
