More wiring work, hot as hell

Wiring clean up

The weekend’s project was cleaning up the rewiring done last month.  This involved some much needed lessons in soldering from Tom (I suck at it.)  After finishing the five joints the connections were cleaned up with shrink tube.  The results look much better.

 

It is unbelievable how hot the dome was today.  The outside temperature was 87 degrees, medications and it seemed much hotter in the dome. More practice was gained in focusing the primary and secondary coelostats.  Standing on the secondary flat structure I actually had a feeling of what it must have been like during the heyday.

I think we can understand why undergraduates choose astrophysics instead of astronomy.

New Safety Ground for Tower 2, and First Solar Images of the Year

Workspace

One of the things I found fascinating at McMath is the slide cabinet. There are several hundred original glass slides (emulsion on glass). From what I can tell, healing these are from the late 30’s and early 40’s.

Damage

The problem is that they were mounted using paper tape and over the years, humidity and heat fluctuation has destroyed many of them. I’m going through them to find those that are in the best condition, and stripping off the disintegrating tape, resealing them with metal tape, cleaning them, and eventually photo archiving them.

This is a tedious labor of love at this point, which I look forward to working on at every chance I get. I am discovering some amazing slides. The projector for them is upstairs and I think we’ll have a blast seeing them displayed.

Progress

Current count of repaired and preserved slides: 20

After another incident of a short, store
a new permanent safety ground has been added. As can be seen, viagra dosage
the jungle of cables are next to be cleaned up.  All controls are working as expected, and the sudden appearance of the sun allowed us to open the optical path an obtain the first solar image of the year.

The mirrors now need to be changed, and we will need all hands aboard for this task.

Rewiring Project Tower 2 at MHO

Sun Through the Shutters

 

 

Last Saturday was another day of rewiring the controls for Tower 2.  The wiring seemed to be a straight forward project, pharm but the process of running wires one at a time left other other original wiring bare and subject to a short. All the wiring will need to be replaced one at time, case for the secondary coleostat also.

 

The secondary coleostat is not a crucial to run electrically, as it effects solar declination only, and can be easily adjusted manually. Nevertheless, all deficient  wiring needs to be replaced.  There are some questions as to the wiring of some controls for the secondary   coleostat, and most probably a wiring diagram after completion would be helpful.

 

Once the weather improves, the telescope will be put into use, and the the problems of focus will be addressed. The culminating lenses need to be cleaned. Negotiations with Richardson Gratings continue, and Debra has started a program to look at funding the new grating.

 

One of the larger projects will be to switch the primary and secondary mirrors.  We have current polished ones, and once we are getting images, this will become more crucial. We will need a lot of muscle that day, so planning and attendance will be critical.

The day was well spent working on clean up of the dome of tower 2, website like this
and rewiring telescope controls The wiring was original copper, cloth covered with petroleum impregnate. The only logical way to do this was replace one wire at time through the conduits. The only thing that made it easier is the newer wire is smaller diameter, which makes things go much smoother as work progresses.

 

We seem to have found a solution to the shutter problems, thanks to Brian. That is up for completion in two weeks.  Then,  time to change the mirrors.  Work on obtaining a new diffraction grating continues.
