I've been bitten  by the stargazing bug again.

I live in a relatively dark area, probably around the darkest in the state. So opportunities for night sky observation are amazing.

When I was a kid I used to enjoy looking at stuff in the night sky and reading astronomy books. I am interested in radio astronomy and I've even visited the Green Bank Telescope in WV. (It's an AMAZING sight).

We bought a Celestron 130mm refractor with computer control.

So far we've been having a blast, and taking the kids to see the stars and planets. So far we've observed the Moon, Jupiter (and the Galilean moons), several binary stars and Saturn, which shows up around  sunrise here.

Any other stargazers here?

I lived in Beaver,  WV for a few years, population 1,100. Real dark skies, I had a 6" reflector and did the lawn chair/sleeping bag routine for the meteor showers. I saw a point meteor, really cool! Have you tried catching an Iridium satellite?  They go to magnitude -8 if the reflection goes right over you.

  I got 10" and 18" Newtonian reflectors I do imaging with. My club has a dark sky site 50 miles out of town. Fairly dark, some members do go further east to get more difficult objects. Lately to chase down Comet C-2012 Q2 (Lovejoy) in less cloudy spots. Despite the Denver "Aurora" (Local pun intended!) expanding. we extended the lease to the property we're on. Most members head out to the mountains in the summer during "star party" event season. There are a few radio astronomer amateurs out there.

Wow that 18" must be pretty sweet! I want to get something of that size eventually.

I'm into amateur radio but I'm intrigued by radio astronomy.

Devyln, I haven't tried for any sats yet even though I've talked to the ISS on my ham radios.

  Speaking of Jupiter, there will be a multiple Galilean event for the night of Jan. 23 to the early morning of the 24th visible in the Americas. The shadow of Callisto will appear on the western limb of Jupiter at 10:13 EST followed by Io shadow transit starts at 11:36; Io transit starts at 11:56; Callisto and Io shadow contact at 12:36am on the 24th, eastern time. Watch carefully at Io's disk on Jupiter after this time! At around 12:51am, the disk of Io will darken from the shadow from Callisto! This will happen quickly. Callisto disc start transit and Io's disc gets in front of Callisto's shadow at 1:20am. Bull's eye effect with Io near the front of Callisto's shadow at 1:29am with Europa shadow start transit. Now you got 5 players on the disk of Jupiter! Europa shadow, Callisto north of that, Callisto shadow with Io exiting and Io shadow near the eastern limb. This goes to 1:51am when Io shadow exits the Jovian disk. 4 players until the disk of Europa starts transit at 2:10am. This second 5 player event lasts a few minutes until Io disk exit transit at around 2:13am. The rest of the players will transit until 6:01am EST when Callisto disk exit the transit. An all nighter on jupiter!
  You should be able to see these events well with the 130mm refracter with hopefully good "seeing". Clear skies!

love stargazing,
i actually have the same telescope, unfortunately where i am its sometimes hard to get a good view of much other than the moon lol

is this only visable from americas? cause its definitely something i would love to see

  The whole series of events will be visible in the Americas. London will see the events up to the second 5 player event, but Jupiter will be low in the western sky. Callisto leaving shortly after sundown in Sydney, Australia. Hawaii will see both 5 player events, low in the east up to the last transit. Not much to see as Jupiter will not be visible in Europe and Asia at these times.

There's a lot on this site, click the Iridium Flares link, enter your location and check the box to include daytime flares. I guarantee the first time you see one, you say "Holy cow!" It's about fifteen seconds start to finish, and absolutely the brightest thing you've ever seen in the sky.

  The Heavens Above website will show other satellite passes, including the ISS. Also ground maps for the ISS passing in front of the Sun or Moon for your locality. A lot of images of the silhouette of the ISS against the Sun or Moon have been made by amateurs using video cameras attached to their telescope using a front solar filter for the Sun.

I use a couple programs for sat tracking for my amateur radio hobby. I also made a radio contact with the ISS once. It was pretty cool.

Looking forward to the event on the 23rd. It's on my calendar!

Eventually we'll get a better scope, but right now I have other expenses. We're having lots of fun with the 130mm refractor though. I may get a few eyepieces, but we have the 4mm and 20mm right now.

I should really start gazing again. Kinda rough living in a city now, buildings and lights blocking me. I been thinking of joining my schools astronomy club, which I heard, has access to some good local observatories. Funny thing is, 20 mins outside of this city is desert and I could do all the star gazing I want in the desert :P

ImagineKate

It has been hard here to take out the scope because it's been so cold and it seems like every few days we get cloudy weather and a snow storm. Maybe when it gets a bit warmer.

We were talking about the stargazing cruises advertised on TV. We may take one of those.

I have a 4.5 inch short focus Newtonian.  In town it is not good for much other than gazing at planets (too much light pollution where I am) but it is small enough and light enough to throw in the trunk of the car and take on weekend trips to the desert, and it sets up easily.  There is no computer control, but I know the sky well enough to aim it by hand.  Learning where things were in the sky was about the only good thing I ever got out of being in boy scouts as a teenager.

  A small, short focus or "fast" Newtonian is a good telescope to start with. I have seen the older of my generation go back to those when decreased mobility becomes a problem. These were the monster Dobsonian guys with the apertures over 20" and the larger of these usually came in a trailer. I looked through apertures to 42" at these star party events and these, though simplified, can be like major construction when these are set up. "Nosebleed" ladders to the eyepiece.
  I started my astronomy after John Glenn went into orbit in 1962. The moon and sky maps became available through various advertisement promotions due to the start of the space race. No telescope, but I started with identifying constellations and star names. I get these cheap 2 lens, green window glass telescopes in a hanging plastic bag from the drugstores for $.75 and tried to look at lunar craters. It is hard for a kid to hold something steady, especially with the Moon directly overhead. Lying on the ground with the tiny telescope's wee tripod on a cardboard box was the method then.
  I got my first "real" telescope when my mom got me a red "Monkey Wards" 3" Newtonian on a cheap ball-and-socket mount for Christmas. I used the Funk & Wagnalls encyclopedia my mom got through a grocery chain promotion to find the selected objects not on those constellation maps such as M-27, the Dumbbell Nebula and M-57, the Ring Nebula visible through that telescope. My brief, 1 1/2 year membership in the Boy Scouts offered no astronomy merit badge with the company I was in. My first astrophotos were taken with a box camera I got at a thrift store. These were the 30 second star trails using Kodak Tri-X film developed in my own darkroom. I had to hold down the "B" shutter on that camera to get these exposures. The camera was propped on a cardboard box and I had to hold still during each exposure.
  I got only one of those pictures that survived the travails of time. That picture has an unique time stamp on it. The time stamp was Jupiter. I was able to find the date and time the picture was taken by the position of Jupiter in the image and the position of the constellation of Scorpius with a ground reference. April 6, 1971 at 2:57 am. It took me less than 5 minutes to find the time using one of the planetarium software that is available.
