Nice photo. I love the Airedale avatar.

I started building my dome 10/01 and finished it in five months. The 42" was added almost two years later as the mirror was late coming in (naturally!) Starting in Amateur Astronomy Magazine issue #33 I wrote a large two part article on designing and building your own wooden dome.
The 24' dome sits in my front yard on the edge of the Chiefland observing field in north Florida.
The scope is a big ugly 1500 pound beast. It uses a square tube to help move the balance point closer to the center of the tube. The tube is fully baffeled, and has internal doors that close over the mirror. The go-to drive was built by Sky Commander.
On nights of good seeing the views are quite good, as nearly 1000 astronomers have seen so far.
If someone will let me know how to add a second photo, I will add the photo of the scope. Thanks!

Once more Welcome Tom!

Thanks, Kent. Why didn't I think of that?
Sorry about the door!
Anyway, here is the big ugly beast. If anyone knows how to build an uglier scope please let me know!
However, being a die-hard visual observer, to me it works beautifully. A 42" brings in a lot of light, and on nights of good seeing the views are wonderful. On other nights, when the seeing is bad, it can't keep up with smaller instruments. Those nights make you wonder if it was worth all the trouble. Oh well, we live for the good nights, right?
So why a dome instead of the more normal roll-off for a Dob? After 20 years of observing, I was tired of the weather, and wanted out of it. What good would six foot high walls be when you are 14' high at the eyepiece? The dome is warmer than being out in the elements, and there is never any dew in a dome. When you miss the open sky you can simply walk out the door.

As far as the dome it works for me. I was in my very first dome just last Saturday night, at the UPEI in Charlottetown and it certainly took the chill off. So no arguments from me.
Beautiful scope, seriously and a really nice ladder to go along with it!

Thanks so much for posting your Observatory.

Here are the reasons I made it 6ft off the ground. 1) I wanted to get up off the ground which is at the lowest spot in my yard, getting out of the vapor. I can turn a hammer in to rust in no time back there. 2) I didn't want rodents under living under it and I doubt a mouse can inside. 3) The extra lift off the ground gave me a little more visibility over my tree line, not much but it helps. 4) Resale of my property will be boosted as this thing would make a wonderful play/tree house—as somebody may not want an observatory. 5) my last reason was that the area I built it was once a flood plane, and not far from a creek, so I wanted it up out of danger. Isn't it funny how our priorities change? Reason #5 quickly became reason # 1. Thats right, I almost named it Uraniborg (see pic). It figures that right after I get the structure done but before the roof is on, it pours for days like we haven't seen for hundreds of years. I hope this observatory is good at catching rare celestial events too
My shed has a trap door instead of a front door. I used a pull down attic ladder as my steps. That works pretty well. I thought it was easier than a door until I built the trap door cover. At that point I think I added work for myself—but I like it and it offers extremely good venting for cool down
When I get around to adding this to my web page, I'll post some links.
