Is the solar filter not used with the projection screen? If course I would never look directly into it. That's what my #12 and 14 welding shades are for. If I had components #11 and 18, I could build a holder for them and use that right-side up, or upside down as shown covered by a piece of paper for projections.

The solar filter is not used with the projection screen.

He's looking for a bracket that attaches to the drawtube that holds a projection screen for solar viewing, not just a filter.
Numbers 11, 18, and 19 on this photo from my Jason 313 manual. I am looking for one too.
I may have that assembly from the old Stein TOWA out in the shed -- I'll take a look... BINGO:
Shoot me a PM if you want it...

In the 1968 Tasco catalog they show a "Sun Diaginal Prism" for sale. The also state it is also called a "Herschel Wedge". Last line in the description is " BUT SOLAR FILTER MUST ALSO BE USED!". Suggesting that this wedge is not enough by itself to be safe. I have ofteon wondered why they included the solar filter with scopes that had the solar projection screen. Save some money and charge the same price for the scope! Or why they included it with any scope? It was cheap enough they included it to make the set look look better? I.E. more stuff to entice the buyer? Or why did they not build the solar filter into the hershell wedge in the first place?

Folks, please let's limit discussions on items in this topic or take them to the proper area in Classic Telescopes. Please read the forum rules at the top of the topic. Thank you.

1971 Criterion RV-6 -- OTA Only
Y'all can thank CHAZ for this one: Ever since I got that Outstanding / Phenomenal / Refractor-Like Meade 826, my RV-6 has been idle. It deserves to be completely restored & USED by a Classic Scope Nut. If you've really wanted one of these fantastic 6" F8 Newts, here's your chance. You get the scope, original finder, & Celestron (Nihon-Seiko) 50mm R/A finder, and the original hinged rings (if you need them). I put a lot of time into restoring the EQ & pedestal, so I'm keeping that for now -- as a backup for my Meade StarFinder...
You pay for the packaging & shipping. Be prepared! FedEx wanted $150 from The Swamp (AL) to Rapid City, SD (about 1500 miles), so plan accordingly. If you've ever seen one of my packing jobs... you know I don't go skimpy!
MY GIFT, MY CONDITIONS:
- No Flipping! No parting-out.
- No adding to an already extensive collection.
- Commitment to finish restoration, and/or to using this scope as intended, for at least one calendar year.
Don't REPLY on this Thread. PM me if you're interested. As usual, my ideal recipient is a younger person / newer Classic Scope Nut who doesn't have a Newt like the RV-6.
I'll keep this offer open for several days to give everyone an opportunity to respond. Also, please put RV-6 in your PM subject so I can keep my Inbox from getting crazier than I am... Thanks!!

I have some leftover pentax parts that I would like to donate. From a black tube 60x800 Jupiter.
Objective is clammy and filthy. Box needs much love.
First consideration given to person doing a restoration and willing to take it all.
If no takers I will part it out. Again first consideration given to a person doing a restoration.
Yours for shipping.

Vixen Polaris tripod hub to head bolt
#1 I believe is the short bolt that comes from under the tripod hub to hold the head onto the hub
I don't know if there was ever a knob version
I also have a 3.5" long threaded bolt that came for one of the Vixen Polaris, Super Polaris, or Great Polaris mount, down near the bottom of the head. Slot head. I don't know the thread size, measures roughly 1/4"

Clamshell, yoke mount, 2 lenses, and ?
All free, just pay shipping. I have a few other things, but could not put my hands on them so I won't list till I do.
Clamshell: looks like it will hold scope about 5-3/8” or 137MM.
Yoke mount: 3-1/8" between holes for scope.
2 lenses: I believe a matched pair, I'm sure you'll want to clean them. About 2-1/4" or 58MM by about 40" or 1016 MM (probably called 60x1000).
?: not a yoke mount, but like one. About 1-1/8" or 30MM between forks. About 1-1/16" or 26MM base part that goes into hole.

I also have a 3" F15 lens for the cost of shipping. Well, about 70%. Top lens is massing a little bit.
Also another clamshell : Not sure what it is for. It was on a small scope I got years ago, maybe someone else needs it now. Very heavy duty. There is no felt or any liner, so sizes are actual. Top part holds 3-3/8"/85MM scope. Bottom portion mounts on 2-5/16"/60MM post. Note - see pictures, these two holes are not for side-by-side scopes. Yours for actual shipping. This weighs about 4 pounds, 12 ounces from 65704.

THE PARTS HAVE BEEN SPOKEN FOR.
For the cost of shipping via Paypal are these parts from a 60mm Sears 6305-A (Towa) and EQ mount. Note there is no tube, objective & cell and no legs. The focuser works well but there’s no visual back. The finder bracket is missing one setscrew and has no mounting screws. The mount is incomplete but if anyone has a similar mount you should be able to scavenge some parts. Send me personal message through CN if you are interested. Mailed from 78634.

12.5mm "Gosky" Plossl going to anyone who wants to pay $4-5 postage on it. No brand on the thing but the view's good through it. Bought off ebay a month ago, used once to show the conjunction to the public. Decided to send it back in order not to even start a huge pile of astronomical equipment I'll never use- seller just refunded me and told me not to return it so here I am donating it.
EDIT: the Plossl has been spoken for!

Mods: if this is the wrong place to post this feel free to move it.
I inherited two 6" Newtonians from a deceased amateur telescope maker and astrophotographer by the name of Bill Hammel from Chester, Connecticut. Bill was clearly quite the tinkerer and seems to have had a number of projects, and among them he had these two scopes. I got a bunch of other things I wanted along with these items that easily were worth the money alone so I'd like to give away these two scopes to beginner astronomers, preferably teenagers. I'm not shipping these so they are pickup only here in Connecticut.
These aren't collector's items. They're not in perfect condition. That being said, I think they can make someone very happy.
The first scope is a 6" f/4 from Chicago Optical Supply that Bill built a mount for. It appears he was trying to copy a Dobsonian based off magazine photos alone and ended up using ball bearings for the thing. That being said the mount is quite smooth and features adjustable tension on both axes with a cradle that allows the tube to rotate and slide back and forth for balance. The scope is technically a "tabletop" being a 6" f/4, but features a big wooden case that doubles as a stand - you simply lift the case off the telescope and set the telescope on top of it. The focuser is 1.25" only but could hold a 2" eyepiece with the right threaded adapter. There's no finder, but you could easily stick a Telrad or Rigel Quikfinder on there. The secondary mirror coatings are great, while the primary is beginning to show signs of age.
The second scope is an Edmund Super Space Conqueror. The focuser is missing a knob, the secondary mirror has a small chip (I might have a spare secondary though), and the primary has some corrosion to the coating along with a chip out of the back. That being said, it still works really well, and the OTA looks quite pretty. It has a finder which I've cleaned. Bill didn't leave a mount with this, but I have a dismantled GEM in the basement from my first Super Space Conqueror that I can dig up and put back together for this thing. I don't have a good picture of this one, but here's a previous Super Space Conqueror I had (albeit with a Telrad) so you know what you're getting into.
As I've said the 6" f/4 needs a finder, and both need eyepieces. I have a dinged up 26mm Tele-Vue Plossl that I could include if absolutely necessary but I'd prefer not to part with it.
If any CNers know anyone who could use either scope (or, heaven forbid, there is actually someone in the CT/NY area my age who wants this) please send me a message. I also have a 6" f/8 mirror set on the way if there's interest....

Maybe someone on the forums will know of a club in the area that could clean them up (if needed) and help find them a good home?
