Looks like a great idea. Have you already used it at night while observing?

Thanks Bob. Not since I put down the new mats but I plan on it getting a lot of use in the coming months with this tripod and mount and my 120mm Vixen petzval refractor. I also have light shields that I can put up on the two sides that need shielding.

I noticed that the Newton rings in my (60/710mm), Kenko's objective were way off to one side so I inspected the spacers. 

After several attempts of doing things like burnishing them making sure they were evenly flat there was no change.

I decided to completely replace them, but once done it didn't change their position at all.

 

Could one of the lenses be suffering from wedge?

I was hoping I could improve it since it's probably the worse performing 60mm I have.

 

Thoughts anyone?

The 2 repainted aluminum plates are back on the Tinsley EQ, and it's ready to carry heavy scopes again.  

 

With the quarantine, I won't be taking the 6" Cassegrain tube to JD any time soon for powder-coating, so I'm gonna clean & collimate it today, on the off-chance that I get to use it tonight -- fingers crossed.

You're quarantined?  Quarantined, to me, means that you have to say away from other people, because you are sick.

 

Myself, I am sequestered, meaning I am avoiding people who are sick, because I am healthy.

 

Don't mean to be picky, but there's a difference. smile.gif

I have been using a QuickSet elevator tripod with my old C90. The tripod itself is very stable but the pan/tilt head is imprecise and wobbly, so I thought about a better solution.

 

I noticed that the Towa EQ mount that came with my Sears 6333 has a cradle that attaches to the mount with two bolts:

P 20200404 134536 P

 

Removing the cradle revealed a flat, diamond-shaped mounting surface:

P 20200404 134622 P
 
A few pieces of scrap aluminum plate, a hacksaw, file and drill, plus some washers, a 1/4 - 20 bolt and two M8 carriage bolts later, and I had this:
P 20200404 134656 P
 
Bolted to the mount plate of the C90:
P 20200405 163449 P
 
And after some trimming and fiddling, firmly bolted to the Towa EQ mount:
P 20200406 132945 P
 
Now, to try it out!
 
This would have been much easier if I had a drill press and a benchtop jigsaw :-)

Put a temporary fix to my 6" f/10 "anti-refractor" until a tube gets made for it.

 

Thanks Thomas Cave for the rotating rings.

I like to refer to my long focus Newts as "Hyperapochromats".

 

My favorite such, the 6" f/10.3 "Kludgescope":

I made the rotating rings on my Harbor Freight mill, with 10" rotary table.

 

For this one, I used lazy suzan bearings, and beefed them up with plywood.  They work very well.  8" f/9, mirror finished by me at the Delmarva mirror class several years ago.

But next time (and for a redo of the rings on my 10" f/6 homebuilt), I plan to copy these wonderfully simply Bill Schafer rings on this 8" f/8 I bought a few years ago.  It was missing the primary, so I found an old pyrex mirror on ebay, refigured it, and now it's recoated and waiting for me to get to this project of restoration:

But first, I need to finish the refigure on the pimary for the Intes MK63.  Getting close!

Working on the mirror cell for the 10" f/7.5 scope.

Have a DS-16 mount for the scope to sit on.

I permanently borrowed a beer cup from the cupboard and made a dew shield for my 51mm Edmund scope.  These scopes make great RFT's but without a dew shield in our climate they dew up quickly.  I have been thinking for some time on how to make a low cost dew shield simply.........My inspiration came from the red beer.

Plastic cups are versatile!  I made a conic baffle for my 5" F5 RFT with a huge SEC cup:

I painted a counterweight today.

Original finish was pretty beat up but I could see it was semi-flat black.

My paint can shelf had a few cans of semi-flat, but no propellant left, even with

the can sitting in the sun.

I did find a can of Russell frame and chassis epoxy, probably 30 years old but 

so I used it, looks nice.

Today I tried something different. I normally squirt paint with me holding the item

in my hand hanging from a wire, stick, etc.

What I did is put a plastic grocery bag over my hand and arm a little past my 

elbow. After painting I removed the bag, no over spray all over me just a few

specks on my nozzle depressor finger.

Just look at those legs! I polished the ‘74 C8 legs since it hadn’t been feeling the love. Had been usuing the TV Genesis lately and not used the C8 in a long while, so I took it out the other night and the views were awesome of the Hercules cluster and M3. So I felt it my duty to clean up the old legs in return for the views it gave me, lol. I first rubbed them down with grey scotchbite pads then followed up with Flitz polish on a buffer pad. Nice and shiny again.

Wearing her badge proudly. Of all the scopes that have come and gone over the years, this one has remained the longest and after the views the other night, it’s not going anywhere soon. It just does a lot of things very well.

spectros 35mm barrel to standard 2" adapter is ready for testing tonight.  Me widening that steel ring from 1.25" to 35mm with my Dremel was like Texas Chainsaw Massacre meets Quantum of Solace...

Wow, 31.75 mm to 35mm! You had to take out 1.625mm or over 6 hundredths of an inch evenly all the way around with a dremel and maintain the center as well as vertical interior sides by hand? That is a feat! You need to get yourself a mini-lathe or make friends with a machinist!
