Posted by: Ron Walker Jan 28 2021, 02:40 PM Just wondering if you would like to be featured in my amateur planetarium column in the IPS Planetarian?

Posted by: albert Jan 29 2021, 06:32 AM Hi Ron, how are ya doin' in these completely crazy times? My planetarium in Bad Toelz (Germany) is in lockdown since the end of October 2020. We had re-opened after the first lockdown in March to admit only 10 people. gaah. but now its zero again. BUT I have realized my dream and gotten a ZKP 2 projector! we had it installed in December and are running tests and rehearsal shows at the moment. This is the real Mc Coy for me. Small but very powerful, with most of the functions of a big ZEISS machine. Just great engineering. I'm also in touch with a Dutch colleague who has recently found the twin of the original Zeiss Model 1 projector. It had disappeared after a fire destroyed the Den Haag planetarium in 1976. The machine was listed a being destroyed by the fire and vanished from sight. The colleague, Romke Schievingk, has found it crated up in the basement of a museum at Eindhoven, I believe. It was not as badly damaged as everyone had thought and he has been able to make it run again. Unbelievable. Even most of the star fields are still intact ...the water from the fire brigade had entered into the starball and was sloshing around in it when the machine was dismantled after the fire. Tough construction! www.youtube.com/watch?v=puDKO1lItMYHere is his documentary. My own video of the demontage of the old ZKP 1 and the setup for the ZKP 2 can be seen here: drive.google.com/file/d/1loYOyii563Zhj65XR85cMeJMateKEI6u/view?usp=sharingIt can be downloaded in 4k resolution. There is talk of getting the second model 1 to work or at least on display for 100 years of Zeiss planetarium in 2023. I will also participate since I'm currently the only guy here in Germany who can demonstrate the two small ZEISS machines in the same room. I have often thought about you and Owen, I hope his collection-or at least parts of it- can also play a role in the celebration of the planetarium centennary. All the best for you- I hope you are still doing shows in your fabulous home built dome. That was such an inspiration to me. Nothing's impossible!!!! albert

Great to see your new projector. You certainly now have a first class planetarium. Also great that the second Zeiss I was found and is still viable. I never realized it was so big until this film. I wish I understood German but the pictures are great. Still doing shows but things have been cut way back. Unfortunately I think this virus or a variant of it will be with us all for a long time to come.

Posted by: Ken Miller Feb 3 2021, 05:43 PM What a beautiful installation! A really nice homage to the old projectors. This place would be amazing to visit, enjoy, and be inspired by.

Posted by: Ron Walker Mar 15 2021, 10:59 AM I would love for Albert to talk about his new ZKP 2 projector and this is a good place for it unless he wants to do a totally new thread which would probably be better.

My guess is the two cylindrical cans coming out of the central core 90 degrees to the east/west axis are the motors for daily and latitude motion?

I also enjoyed the 3 videos. 2 posted back in January, and this more recent one on March 17.
While I also realized my 2 years of high school German only caught about 6 words (my Teacher Wolfgang Von Haller would be disappointed in me; he usually was anyway!) it was wonderful to watch these very skilled people go about the task of putting this machine and console back together again.
It reminded me of some of my trips to remove machines (in reverse) and made me understand what it could look like with skilled and knowledge people at the helm. My "adventures" were plagued with a lot of "I wonder what we should do now?" and "Do you think it is OK to cut this wire?" mm

One of the things I learned soon after I started my own business was that it didn't take much to do a thing and just a little bit more to do it right. That little extra to do it right often saved hours and hours of problems and heartbreak later. Take the time and do it right the first time, you WILL be thankful.

Thus, if we modify the "99% rule of projects" slightly we can conclude that "the first 10% of any project will require 90% of the time to do it right. The last 90% of the project will require the OTHER 90% of the time to do it right." (In a simplified way. what ever time you think something will take or no matter what you think something will cost; DOUBLE your estimate. Then you will be close! mm

It could be more then that...have you priced anything lately? However a small dome in a bedroom would at least be an inexpensive stepping stone for you to enjoy a sky until you can build your big one.

Speaking from personal experience, that is exactly on the mark. In my time I planned out many engineering projects, costing, scheduling, and submitting quotes. If you have done the exact project at least once before, you may get away with only adding 50% to the cost.

Yes, you're right, Ron. The other motors are either inside the middle part of the machine (hour circle and precession) or inside the base (polar height, with a long arbor going up inside one of the posts) When the machine is open it is like clockwork, some of the parts look pretty thin and fragile. The larger motors have been changed for modern servo types. The machine is noiseless when running. Zkp 1 is more like an old Singer sewing machine.
I, too, am surprised at the fact some of my posts here are 11 years old....we opened the planetarium in 2014 and were up and running with the ZKP 1 for all these years. The ZKP 2 only came along in December of 2020.. NEVER GIVE UP YOUR DREAMS!
Albert
