    Observatory Reconstruction Is Beginning!

Give Us A Few Weeks And You'll Have Building To Visit!



Boldly Go Were Few Have Gone Before!


Observatory re-construction will begin very soon.  The weather is finally starting to behave like spring!  Now it's only a matter of coordinating the schedules of volunteers who have the expertise and equipment to do the job!  As soon as we start, I will post photos of our progress on the news page.

Both of our April offerings were clouded out.  We have yet to have the weather cooperate for any of the scheduled viewing sessions so far!  We'll keep trying.  With Daylight Savings Time, sunset times are getting pretty late and true darkness - then end of astronomical twilight is after 11:00 PM!  This is the reason for the late start of viewing sessions this month and throughout the summer.  See below.

If it is cold the night of an observing session.  Dress warmer than you could imagine needing and you should be comfortable. Bring a lawn chair too if possible  These observing sessions will be at the new site even though the observatory is not there yet.  Please note these sessions will be cancelled if the sky conditions/weather are not good.  What does that mean?  Well, (optical) telescopes can't see through clouds!  It will need to be almost perfectly clear.  The next potential problem is wind.  If the wind velocity is more than about 10 mi/hr - that's too much! A telescope magnifies the size of the objects we view - and the effects of the wind!  Please check the ClearSkyClock and weather links on the home page of this site!  What if you're in doubt the observing session will take place?  If it's not perfectly clear and calm, you can call (308) 293-5776 before leaving for the session.!

Here's a link for directions to the observatory starting from O'Neill: 

From O'Neill Nebraska take US HWY 281 north to Road 883 (Johnson's Three Eagles).  Turn left (west) 2 miles to 490 Avenue.  Turn right (north) 0.6 mile to the red gate.  You will be given directions where to park at that point!  I will be putting up signs on the highway and at Ave 490 that say "Star Party"  Please call or e-mail to register so I know how many people to plan for!

When visiting the observatory, here are some rules/recommendations you should consider:

1) Please stay in or close to the observatory.  This facility is located on private property, which is not mine.  Please show your thanks to the owners by keeping the area clean and undisturbed.
2) Please, while in the observatory, don't touch anything unless you ask and/or have been instructed as to the proper use of the instrument!
3) Bring a lawn chair for each member of your group, that is if you plan on staying a while, as we hope you will. If it is clear, please keep in mind that it often takes a while to find objects for you to look at. Often there are others in line to see these things as well. If it is cloudy, you are welcome to pull up a chair and ask as many questions as you like. We have some chairs, but not many.
4) Bring a flashlight for dark-sky observing sessions!  (If the moon is in the sky, you may not need it.) You will need one of these to safely navigate from your car to the building. We purposely don't have any lights in the area of the facility. Once in the building, we generally ask that you don't use your flashlight (with its white bulb) unless you ask. We have red lights which will help you see where you are going inside the building!
5) No smoking is allowed in or around the building!
6)  In winter, please bring plenty of warm clothing! This can't be over stressed. Standing still in the cold is nothing like being active in it! Wear several layers and don't forget those gloves/mittens and something for your head. There is no such thing as glamour when it comes to staying warm!  There is no heat in the observatory!
7) In Summer - don't forget the mosquito repellant!
8) Be advised there are no bathroom facilities in the observatory!
9) No boisterous behavior within the observatory, or around it, will be tolerated!
10)  Help us keep gates closed so as to not let cattle out!  Please don't disturb the cattle.  If you like them, admire them from a distance!
