Yesterday, I puttered inside with painting the ota, reading, and sorting lenses. A fun way to while away a rainy afternoon.
Another article, sent from a friend in the 60mm Telescope Club:

Fascinating article!

Yes, it is. That's sort of my aim, so to speak. The focuser will take 1.25" eyepieces, and should habe enough in focus for a diagonal.
Do you think the good Signore would approve of a pipe mount?

I don't know. Would he?

 

Good to know that the scope will take standard eyepieces. Otherwise, that would have to be designed from scratch as well!

Listening to Renaissance music (recorder, hammered dulcimer, lute, oboe and violin) while applying filigree to the Galileo telescopium. I should be wearing long flowing silk and velvet robes and surplice, and a fancy headovering, but sneakers and an apron must suffice....

Nah, I'm not anywhere near as pretty as those Italian ladies. Too skinny, dorky, and hair cut short. The lady above suits the scope more than I do...

I think you're just being modest.

Well, the Galileian OTA is pretty much done except the eyepieces and objective "ring", and a final coat of clear sealer.
I had a fine week of rainy afternoons to play with the decoration a little at a time.
I cemented red and black craft foam onto the tube and ends, building up the layers. Then painted, wiped, dabbled and sanded till a faux leather appearance was achieved.
The gilding was really fun. Although I used to be quite skilled at decorative and miniature painting, free hand is no longer an option. Four packs of metallic water-transfer gold metallic tattoos (yes, there is such a thing, someone must wear them , and China makes them, cheap!) provided a good choice of design. So I cut, sorted and applied a little at a time. Don, a model maker experienced with transfer decals was a great help.
Touch up with a gold paint marker hides the many glitches, and provided further unneeded embellishment. Really fun to pull out the stops and make something so fancy as a midwinter project.

Woooow! Just...wow. That's simply beautiful, and so faithful to Galileo's original.

 

Excellent work, Vesper!

Thank you all. The proof is in the pudding. Although SurplusShed lenses should be better than Galileos, the view will be no-doubt unimpressive to the modern jaded eye. One seeks to see how he saw. Galileo observed and changed the world.

First sunny day in ages. But too chilly and breezy to put the protective clear coat on the scope.

Wow Carol!  It is a work of art.  And craftsmanship.  It's "performance" art -- lovely form, practical function.  So different in appearance from our vintage (& modern) scopes, and yet...  point it up to the sky, and enjoy the views.

 

BIF:  This thread should be pinned to the top of the Forum.

Just swap in an inexpensive apo objective, Vesper, and it would be perfect.

On another thread (in Refractors) I posted this:

https://www.cloudyni...t/#entry9207147

 

An appeal for any glass pushers out there who have a Ronchi screen to mess up a couple of lenses for me - corrupt an outer zone of similar size to lenses in the time of Galileo. I can post Ronchi images from Willach's "The Long History of the Invention of the Telescope" to give an idea of what those lenses were like.

 

I want to be able to demonstrate the effect of aperture masking, and for that I need two. I will provide the lenses.

 

I have thought of simulating the effect by painting transparent cement of some kind on the lens, but would prefer to have misground lenses instead.

Sunny warmish day today. I hung the OTA on a copper pipe and couple of old tripods, and gave it the final coats of clear matte finish.
Going by Michael's to get a compass and new blades to cut out foam rings for the objective holder and eyepieces.

in the book "the history of the telescope" by H King

page 61 fig 28 describes proposals by Robert Hooke to

shorten the length of singlet refracting telescopes by using mirrors

to fold optical path. however in 1668 polishing "flats that were good enough 

did not exist

 

 

well here is the telescope that never was 

50mm 4000mm Fl f/80 singlet 

works quite well - a little residual color

I placed a copy of the only known image of Hooke

its from a stain glass window n England that was destroyed in an IRA attack

 

Hooke suffered a small pox attack at a young age that left him disfigured 

there are no known paintings of him

 

 Issac Newton and him did not get along and once called Hooke "that ugly little man"

This last week, the rainy ATM weather quit, so I've been outside in the spring sunshine. Im going to set up a small work/paint area on the balcony after clearing out some winter accumulation.
The scope is coming along slowly. The objective is set in place with temporary "rings", and I have narrowed lenses down for 3 eyepieces, -100mm and -47mm Gallileian, and a DCX 50mm fl Keplerian. It's getting there.
