 Not a huge fan of orange so thinking of repainting the tube to white. Any objections? 

Blasphemy!

 

Hard to find in such good condition.

Picked up this unusual Celestron/Vixen 8x50 finder recently and am almost done with a thorough cleaning. The doublet objective was super dirty but cleaned up beautifully and is now yielding superb images. This little guy with removable diagonal and eyepiece plus very nice helical focuser is really more of a small refractor than a viewfinder. Not a huge fan of orange so thinking of repainting the tube to white. Any objections? 

That was when finders were finders.  I also loved the Meade 60mm RA finders in blue in the 1990's. Just gotta watch the plastic housing for the diagonal as they can crack.

There is likely someone with an orange tube Celestron that would love it in original condition.

 

Ironically I have the same one originally in black but painted it with Rustoleum Harvest Orange a couple of months ago to,pair with my C11.

The poles are closed and the votes have been tallied at 3 against and 1 for the repainting so Celestron orange it will stay!

I have this Celestron GP-C102 optical tube.

Over the last few nights I noticed it's performance is outstanding. A very well made 4 inch f/9.8 achromat. 

It's on a Unistar alt/az mount and surveyor's tripod for something different than my usual newt.

Side mounted Telrad at center of balance is taking advantage of free mounting holes on the tube rings, works well.

End of an Era...  Took my J6's tube to JD yesterday for powder-coat.  Met the nice young woman who's buying his business -- she powder-coated my 2 Tak TS fracs, so she's already set a high bar for herself.  Hate to see JD retire, but great to see an apprentice become a boss...

Whenever I see a clamchip, you've just got to think positive!

Let's accentuate the positive! here's your medicine:

C8 SP Onstep.jpg Long project but here is what I did.  When I purchased my Orion/Vixen FL102s from a user on this site, he gave me a nice Super Polaris mount along with the scope (Thank you Steve).  Over the last few months cleaned and re-greased the mount, and converted it to go-to.  It was a DIY project using a 3d printer board as the controller and public available software developed by Howard Dutton in Ardino based code.  Extensive documentation on the Onstep Wiki provides some pretty good guidance on the build, but it does take time and trail and error.  But now I have a very sturdy mount that can handle all my scopes that I can link up with sky safari and have a nice goto rig, at considerably less cost and can fix if anything breaks.

 

Next step was to defork my 1974 sandcast C8 with great optics (no worries saving everything) and now can enjoy a quick set up, without having to assemble the triangle mount tripod, mounting the wedge, and hoisting the heavy sandcast base and hoping I don't drop anything and get it all screwed tightly.

 

Now one mount that i can use either the FL102s and C8, and reduce the amount of stuff I have to lug out for observing or outreaches.

Too windy to do any observing so I refined the slow motion control on the 114 mount I worked on in Post 7056.

 

Drilled-Insert.jpg

I drilled a deeper hole in the insert to keep it more secure

 

Screwed.jpg

At Ace I found a 5-40 screw that fit the threads well but was a little too long.

It was trimmed and rounded so it fit into the the new hole just right.

This was done since the mount's original screw just barely kissed it.

 

New-Control.jpg

The first threaded shaft was a little bent and too long so I cut a new brass screw.

It was cut, filed and polished so it's slightly rounded and smoother.

Then a little aluminum collar was added for looks.

 

Spring-Spacer.jpg

The replacement spring was a little soft so I added a nylon spacer to firm up the pressure

 

114-Mount.jpg

This mount was in really sad shape when I got it, so it's already been cleaned up some.

Now I need to regrease the other control and touch up the scratches.

Today I was planning to remove the dew shield from my 4 inch f/15 Jaegers/Vixen and shorten it.

The last time I observed with this scope I thought I had a little tube-current activity in my long long dew shield.

Well, once I removed the dew shield I could see I was thinking when I made it as long as I did because the

lens cell extends way inside the dew shield and probably comes out to the scientifically correct one and a half

the diameter long.

This tube spent a spell unused until one day I decided to attach a Antares Research Grade Vixen Spec lens

to it. The lens is made by Vixen for Antares but Antares was not allowed to use the Vixen name and is why

it is "Vixen Spec."

Actually though, at the time (1990's) these lenses were made Carton was making the lenses for Vixen, except

the Fluorite lenses which came from Canon.

I'll pick up my Jaegers 6" tube towards the end of the week.  Meanwhile, I've been cleaning & checking the other OTA hardware...

 

- Inner & Outer Lens Cells are both machined aluminum, and anodized black.  Inner weighs 2#, and Outer weighs 3#.  The Lens itself tips the scales at 10.3 lbs -- that's a lot of glass!

 

- Back Plate with Edmund 2" Focuser is just over 3#.

 

- The OTA Cage / Cradle is equally hefty.  I'm thinking about wrapping the dovetail "handle" for comfort.

 

I'll post some pix in a bit.  I'm not 100% sure the Lens Cell is Jaegers (referencing the 2 PDF catalogs that I have), but I'll leave that up to the experts.  If it is, then I think the Dakin may be, too.  Very similar machining.  Or, the Dakin maker modeled it on Jaegers and/or Edmund hardware.

Installed a 2-speed focuser on my 8” f/6 Celestron Starhopper Dob. Had to first patch the hole from the other focuser which had a different bolt pattern and required a larger hole. I cut from file folders about 20 discs slightly smaller than the hole and two squares for the inner and outer tube surfaces. Glued a square on the inside, then stacked the discs with glue in between each piece until nearly flush with the outer surface. Filled the gap around the disc stack with glue then glued the remaining square atop it. Let it dry then hole sawed and drilled for the new focuser mount plate. It worked pretty well. I used wood glue but epoxy or maybe construction cement should also work. Collimated and ready for the next clear night.

I'm getting my Celestron SCT ready for some observing and its time to select a finder for it.

What would really be the cat's meow is a finder with a adjustable eyepiece that can go from straight

thru to 90, not too bulky otherwise I'll hit my forehead on it.

This is when I need Edmund Scientific and all those cool surplus gadgets and gun sights and things.

I miss you Edmund !

Wait a minute, how about a Unitron Duotron isn't it a duel port job, I wonder how they did that, a beam

splitter prism, hmm...

What I've done in the past is use a hand held mirror to look thru the finder for RA. It works ok if I need a finder at

high elevation for a short term.

This is a two (2) person post.  I woke up at 6:00 this morning to meet a fellow member Barry (Defenderslideguitar).  Made a two (2) hour trip each way to pickup a Swift 831.  He graciously viewed the scope, picked it, held it at his house, and hand delivered it to me at 8:30.  We chatted and talked a few times about the scope.  I contacted the seller and negotiated and price.  The scope crossed four (4) states today- Connecticut, New York, New Jersey, and Pennsylvania.  I took a few pictures and cleaned the OTA.  I did some general inspection to be ready for a cleaning and return to service.  The scope had been sitting in the case since 1986 and was "Found" when the seller planned to move to Florida.  It was his father's scope and he really doesn't have an attached to it or astronomy.  Between work, family life, and vacation, I don't think it will see much light for a couple weeks.  

 

Based on pictures, YouTube videos from a member, and instructions, it looks like it is missing the secondary draw tube, but that will be another post or PM.

 

Edit: the draw tube was frozen solid in the focuser.  I was able to get it free with some IPA.  There was a residue on the draw tube but it is cleaned and functioning.  Looks like I have a winner.
