I made some progress on my Jaegers 5 inch f/5.

I realized these are new Jaegers parts, they have never been used on a scope before. 

I was thinking that as I was drilling the holes. I was also thinking this just might as

well be 1972, the parts are the same, just like they came in the mail from Jaegers yesterday.

The tools are the same, I haven't changed much.

I'm using only hand tools, hand drill, hand taps, etc. just like your average person will

have, or can beg borrow or steal very easily.

If you take your time marking things out, squaring things up, you can make a telescope

just as good as anybody's, probably better !

I started today with a piece of firewood around 4-3/4" diameter to slide into the tube

so I can bang the wrinkles out of the tube. Use only a wood or plastic hammer for this

you do not want to expand the metal.

Check your fits, nice sliding fit for the cell on one end focuser on the other, nice easy

sliding fit, you don't want strain or stress  anywhere on your telescope.

Drill some holes, and tap some threads, and you are nearly done.

Robert

I had a dent in a tube, and thru someone's suggestion here on CN, I made this tool:

I think you can get an idea from this, but I think what you have already done would work.  The wood has the ID of the tube, and another section has the OD.

 

I used the above to to straighten out the end of a Swift that was in the process of being powder coated.  They dropped the tube on the threaded cell end.  I was able to straighten it out perfectly and the cell spun right on.

This was the dent:

Here's the fasteners I picked for the Jaegers.

6-32 thread, mil spec cadmium plated truss head for the focuser it's a nice head for not catching clothing

and 6-32 set screws to hold the cell on. I like the idea using set screws (Jaegers' idea) for the cell because collimation is possible.

I may switch to point tip set screws for more gripping power, the last thing I want is another clamchip !

Here's point tip or cone tip set screws:

I flock paper lined the Jaegers tube today.

Jaegers shows baffles but I learned from TeleVue sometimes you don't need baffles.

I'll know soon enough, it will hurt contrast. I've had good luck with flock paper on the

fast lenses.

Decided to go ahead and convert the SPC8 from the original Vixen SP dovetail to a Losmandy type.  I've already had a ADM dual Vixen/Losmandy saddle on the SP mount for a couple of years, and whenever I went to use the C8, I'd have to take that saddle off to accomodate it.  Now the C8 can ride on the SP and Carton mounts both.

I finished the Jaegers 5 inch f/5 today.

Daytime low power is excellent. Deadly sharp and high contrast. This is a cemented doublet so

no spacers or anything to play with its perfect out of the box.

Start increasing power and CA is right there ready and waiting for anyone foolish enough to try !

Its not supposed to be a planetary scope.

I can see it's going to great for it's intended purpose, pack as many stars into the field of view as

possible !

About 50X I can start to see purple fringing on one side of focus, yellow/green fringe on the other.

At focus it's free of CA but daytime atmosphere conditions shows moments of focus change and I

will see flashes of purple during these.

For nature it's incredible at 23X with ether Edmund 28mm or TeleVue 26mm Plossl.

I added safety chain to my Unitron 114.

IMG_3722.JPG

Did  some touch ups on the mount.  Ford Shadow Black paint is a very good match to the gloss black on these mounts.  I use micro-dabbers from Automotive Touch Up.  They hold 1/8th of a drop of paint so you can do touch up very precisely.

All morning I've been thinking of a way to shorten the eyepiece height of my

Cave 10 inch f/5. I've decided its cheaper to find a taller chair !

The problem is I need a bigger telescope. If it were bigger I could have

an observer's cage at the eyepiece, problem solved !

The last part of today I decided to try something I really didn't want to do, put all my

scopes in my shop away out of reach except one, so I'm forced to use my Cave 10 inch.

You see what's happening is I go out there and just grab something easy. It's the Cave

I really want to look thru but the temptation to be Mr. Lazy is strong.

Now this could easily backfire. Now I might not want to observe at all because its too

much trouble. Well I need to make myself a spanking machine if I'm going to be that

way.

But at least it would be a classic spanking machine.

In response to a few likes:

I wonder what choices he would have made a decade later.

Dobs, meade 8800 or 6600 (ie a shorter newt with a light, high quality mount) and a first generation paracorr, the starfinders, etc.

Maybe rod wouldnt be the rodwe know!

The C-102F has gotten a few updates recently- I moved it to an Orion SkyView deluxe mount, which needed a complete teardown to remove some play. Then it got a more era-appropriate wooden tripod, which looks much nicer than the Meade standard field tripod. IAnd just yesterday I got a 3D printed custom dust cap from fellow CN member buckeyestargazer! It's coming together smile.gif

Today I did two things to make my observing life better.

I bought a smaller platform truck from Harbor Freight so now I can get my chair up close

to the telescope on 3 sides instead of only 2 sides, I like it.

Second thing is the "finder on a stick" finding was a neck breaker before mounted in the Telrad

base down the tube. I'd love to move the Telrad base up the tube but I think everyone knows

what will happen if I try and unstick a Telrad base on a cardboard tube. I've studied it and it is

stuck good.
