This looks very nice Steve. Looking forward to seeing it all together. I know you have commented about proceeding slowly with the restoration and it looks definitely worth it.

I have heard of taking your time. This is almost a career :lol:

Just teasing Steve. You are doing a great job.

I have 8 foot ceilings and I just do not leave them set up anymore. Dings in the ceiling, my son running into the counterweight ( it is funny) :lol: and tripping over the tripod.

Yes, thank Johann indeed. I got a much needed tripod bolt just a week or so ago from none other than our dear Johann. :flower:

Every shot looks better and better. You are not alone on the higher ceilings thing. My scopes have been banished to the lower levels of the home. Pretty tight.

In reality banished is probably a most strong term. It is probably the best place. :smirk:

And with my ugly mug for size comparison - I am 6' tall. I did not attach the guidescope or sliding weight bar yet, but it is Mother's day after all!

Very nice Steve, Great looking 152, not many like this around. I can relate to the 1950s details. Few folks know how much better the machining, fit and finish are on these than the later models. Also the optics on the older OTAs seem to all be very good.

Thanks. Clint, with the guide scope and sliding counterweight attached, does it become a 155?

I believe that answer can be found in the Unitron catalog

Steve,

The transformation from last Oct. is impressive :bow:

An early 152, being an original unit is a rarity would be my guess.

Have you decided on which objective?

I hope it's now just the motor drive that you would need for a 155 transformation.

Great thread!

Thanks

Bill

Anyone have this, only about 1/2" shorter? My scope originally came from FL area, and just can't adjust to my WI 43 degrees. I would be happy to swap with some of my southern friends!

One solution suggested is to have a machinist cut about 1/2" from the threaded screw and the collar, but that would certainly be permanent.

You're getting close, Add a shelf light (small thread version) and it would be a full 155. Find the bracket and electric drive and you would have a 155E.
Then the 160 would have an extra slow motion control on the DEC (for guiding) A metal tripod tray and a notch in the mount base for the weight drive linkage.
As to your turnbuckle dilemma. I might have a short turn buckle from the lost unitron, My first 4" came from Norway and Peter at Unitron sent me a longer one for a hefty fee. I will have to do some digging and see if I still have the short one!! :lol:

I am looking Steve. I know I had a shorter one. I do not think I sold it with a mount. I looked last night, but did not have time to look through everything. I remember selling a mount and the guy complained about the shorter adjuster and sent it back and I sent him a longer one.

The short one I have is a later model and takes threaded bolt from both sides. Also as I remember the original long one peter sent me only had one bolt with it so I used one of my original bolts, now I have a short reversed thread center nut and one bolt. You might call Peter at unitron and see if he has any more. he was have a local reproduce these. I measured the one on my old 152 and it is the same exact one as you have And in my opinion much cooler than the new ones!
