Worked on a mirror cell today, with a little help

from one of my friend's "mouse traps".

>>I've always wanted to mount an ETX90 to a Criterion 4000 fork drive...

 

That seems like a nice combination.

 

Speaking of ETX90's, I took the wedge head off my ETX90 tripod (a "DT1" which seems to be a no-name clone of the #883) and ran a 3/8"-16 bolt through the hole in the tripod base to mount a Desert Sky DSV-M which I recently bought used.

 

The result is surprisingly solid with the 80mm f/6 Stellarvue AT1010. Really needs an extension column but usable as is with some tripod movement. This gives me a really light grab & go rig for the first time** and frees up the AZ8 for the AT115 & C8. It would be nice to say that my master plan is coming together but this has been more of a random walk.

 

Yes I need to remember where I put the set screws that hold the laser into the empty bracket. And yes the handle is pointing the wrong way laugh.gif

 

** I originally had the AT1010 sitting on a cheap photo tripod but that was not a particularly usable setup so I'm pretending it never happened. Same for DSV-M on the cheap tripod.

Did some experimenting with a Zeiss Barlow 1.3 on my Telementor. I was lucky to find this extremely rare accessory item after years of searching. I consider the Zeiss Barlow 1.3 a great addition for advancing the magnification potential of any Zeiss refractor. Unlike with cheap Barlows, the Zeiss 1.3 will not compromise picture quality at all. I used my 6mm Zeiss Ortho with the 1.3 Zeiss Barlow and found image quality on par with sharpness, contrast and detail utilizing the ridiculously expensive Zeiss 4mm Ortho at only marginally less magnification. The 1.3 Zeiss Barlow mounted in front of my 4 barrel Zeiss turret is uppening the magnification spectrum tremendously. Great on nights with steady air. Never thought much of Barlow lenses. My Zeiss Barlow 1.3 is a keeper. 

On the other end smile.gif , i have been playing with the extreme "affordable" solution to the Zeiss turret 

 

So far, in combination with the Skymeca Quck Change Adapter, the Q-turret makes the observation easier as i do not need to change EP´s so often and the Telementor has no issue with the weight

At first sight I thought, "D**n funny brake drum." 

 

Once drove through the Green Mts. with a calico in that position helping me drive. Nothing will teach you to take the curve as smoothly as possible than a cat hang'in on your neck!

Here is the wedge with a Questar adapter plate that I made last summer. After polar alignment, the polar alignment scope and it’s mounting are swapped out with the Questar mounting plate and then the Q is mounted, all precisely polar-aligned and ready to locate objects with its setting circles and clock drive.

Roger Tuthill sold one similar this. 

 

O.K.  I had my 4 minutes of rest from the last "scope build/restore" project.

Started to collect parts for the next one.

 

10" f/7.5 project will commence soon.

 

 

Just sold an Onstep kit to a fellow in Calif. who is working on this mount. Said he had a Byers on RA was looking for something for Dec. So I tossed in a 180 tooth Meade crown and worm. Beats hobbing one.

Finished overhauling the EQ mount for my Sears 6339, and fixed it to the top plate of my SpectraPhysics surveyor's tripod. It's stable but very heavy.

I finished the new focus adapter for the Tasco 6vte "tasconado". The draw tube is 1.5" brass sink tube with a compression fitting attached to the f12 OTA. Attached to the tube is a 1.25" svbony helical focuser. Seems to work well, but it's cloudy here....

Small Project, Big Time (& Effort):  I love the spectros eyepieces & Amici prism diagonal with the 35mm barrels, but I have only 1 focuser that'll take these without using the step-down to 1.25" adapter:

 

spectros Eyepiece Set 20160721 S01.jpg

 

... and that's my Tinsley Cassegrain.  (It also worked with that Unitron 142, but I sold it.)

 

Now that I have a bunch of scopes with 2" focusers, I want an adapter that'll fit the 35mm stuff to the 2" scopes without any vignetting.  Rummaging in the shed, I found a thread-in ring and a short chrome 2" focuser tube that the ring fits.  Cool.  But the ring is bored for 1.25" accessories.  Bummer.  But the ring is brass, a soft metal that I can work with my limited machining tools.  Cool.  I marked the ring for a 35.5mm opening.  All I have to do is remove 2mm of metal, and I'll have my adapter.  Oh, Yes!  I turned my Dremel on it, and quickly cut through... what turned out to be a .25mm thick brass band/bushing inside a steel doughnut.  Oh, No!  Cutting stopped, and grinding started.  Stopped when my hand went numb.  Still have about 1mm of steel to grind away...

 

Kept telling myself, No pain, no gain!   These spectros eyepieces are BB's Zeiss set (as close as I'll ever get), and they're worth the effort.  Carpal Tunnel is reversible, right?!

What did you do to your mount   ?          I left the mount in the trunk ..................

 

I met the seller (GoodAsh) in the  parking lot to pick up this CG-5 for his  low low price

 

Our new protocol went like this.... I pull in and I  park ten feet away and opened my  trunk... The cash is in the trunk and has been there 2 days......Seller takes the mount from his trunk wipes down the mount and puts it in my trunk. He takes the cash and we chat  from ten feet away. We agree that extra precautions are not foolish. Agree to talk again ... hopefully at Neaf.    I will leave the mount in the trunk for a couple of days. The 17 year old sedan does not complain.

 

My first CG-5

Today, I used a few scraps of wood to build a small eyepiece tray that clamps onto the semi-pier of the 4" F10, Babbitt bearing, pipe mount. Since I mainly only use three eyepieces, when I observe, it didn't need to be that large. Once the current travel restrictions are lifted, I'll pick up some red oak and rebuild it, (along lessons learned from my first attempt) so it will match wood of the tripod.

On the same "scrap of wood" trend, constructed a solar projection screen for my old Jason 313 from leftovers from our kitchen install:

Pinky the cat doesn't seem impressed; perhaps that'll change after it gets a white screen.

I ordered four 1/2” thick 3’x3’ interlocking rubber waffle shop-mats online at Lowes yesterday and we drove through customer pickup to get them yesterday afternoon. I put them down over the 1/2” thick dense rubber 6’x8’ mat that rests on sand. Absolutely no vibrations, it’s very easy on the knees and feet and tripod feet go right into the holes in the mats so no spreader needed. It will be perfect for the surveyors tripod that has the 1” shaft Jaegers GEM that I rebuilt last fall.
