Quote:Hello Chris,Thank you for the schematic, very impressive.Accomplished last nights test again today with a 12 volt and a 6 volt automotive battery wired in series (18.7 volts) with a 3 amp fuse. Basically all of the same craziness that occurred last night happened again but it took less than 3 minutes to start during each of the three attemps this time. Had PEC one time, Motor Stalled another, no fingerprinting message.Did notice one more thing that I had not noticed before. When the dec full speed slew stopped I could hear the dec motor still turning at a very slow speed for a few seconds before it completely stopped. Decided to call Meade today and see what I could buy from then in the way of parts. They said I could get a new hand box and cable. I said here is my credit card number. He thought a minute and said - Well, since your scope is under warranty we will send it to you at no charge. The first thing I suggested to this guy in my email to him, over a week ago, explaining my problems, was to try these first. Have talked to him several times since, but was never informed they were available. The only other thing I can get is a new power supply, but customer support doesn't have them, have to buy them off the web site.Pulled the harness out of the RH shaft, went hand over hand down to the first tywrap, not a scratch. Will go further tomorrow.Since, I assume, that only dec and GPS wires go through the RA shaft, how could a fault in these wires cause all of the RH craziness without having the dec slew also? RA slewing is happening much more often now then it use to and now also even before dec slewing begins. Seems to me that the only things common to both are the hand box, it's cable and the main board.Since I can not find any wire damage, could a open or short, such as when something inside a chip heats up, be causing this? Once it starts no matter how many restarts I do, there is no joy. After along break, the next day, first start always okay.ObservatoryCat
Quote:Hello Chris,Thank you for all of the good information. Might have to reinstall my 1970's era orange tube C8 or C14 back on the pier for awhile.My retired SLAC friend has a C12 and he is considering installing one of those systems. I will look into it.To see my observatory, telescope and images please look at www.flickr.com/photos/myobservatory To watch a video, part of which includes me operating the telescope, please look at https://Vimeo.com/44062171 password "cosmos". This was a class project of students in the M.F.A. program at Stanford University.ObservatoryCat
Quote:And of course given Meade's current financial situation it could all become moot.And another thing about Meade's current financial situation, at this time I would NOT send them your scope or any part of it. There is a certain amount of risk that you might not ever get it back if they close their doors while your scope or parts of it are in their shop.I hope this helps.

Quote:Not true, a bankruptcy trusty would return all equipment/assets not owned by the 'company' to its rightful owner. It may take time to sort it out, but, it would not be liquidated, at least not on purpose. Keep good records and you should be OK.Tony
Quote:A bunch of debris got added to the end of it somehow. It is shown correctly. I edited it, worked for me now.
Quote:Hello Chris,Just type in the address and you will be fine. However, my stuff may not be worth the effort.I sure would appreciate your opinion and advice about replacing the Meade electronics. I really hate the idea of sending the telescope away for something I could easily replace myself. I looked on the Software Bisque site and was amazed by the lack of information, or do I just not know how to find it? What do they supply, what does it look like, what do I need to supply, what will I need to build (have a friend who can machine almost anything), can I use SkyTools with it, can I use the Telescope Drive Master encoder. The only way I can figure this out is to hear from you and talk to them on the phone.The floor plan of My Observatory and the pier I built were all configured in 1979 for an orange tube C14. Got the 16" LX200 as an upgrade because all I need to do was to make an adapter plate so I could bolt it onto the pier. The mount bolts just clear and I mean JUST clear the 12 OD of the pier.If you ever fly into SFOIA I live and My Observatory is two miles from the terminals. Walked to work there since 1975, retired from UAL after 43 years.Thanks,ObservatoryCat
Quote:Does anyone out there know if somebody makes a sling for lifting the 16" OTA? I may just try and make one myself!

Quote:Quote:Does anyone out there know if somebody makes a sling for lifting the 16" OTA? I may just try and make one myself! I use a game hoist from Cabella's to set up and tear down my 16 in the field but I don't think it will work for you inside of an observatory.A 4x4 across the top of the open aperture of your Ash dome combined with a couple of hoists would work. Ash domes are very strong and the OTA assembly only weighs 125 pounds.Or two-to-four burly guys and two short ladders.I hope this helps.
I like what you have done, I had planned to put my 14" in a sling, but attaching to the 5000 series plate could work. I wonder if it is designed to hold the 63#s of the 14"?
Quote:...The telescope is working great, no runaways. Replaced the broken receptacle on the wires that attach to the declination servomotor encoder, used Stabilant 22, and have completed the telescoping bar that fits in the shutter tracks so that I can lift the OTA with a small hoist. Just need the ambition and some cloudy skies to get to work and take it down so I can reposition the RA servomotor board.ObservatoryCat
