That is an iris diaphragm, right?   The secrets to fixing them in camera lenses are:  (1) get them absolutely clean, with not a hint of grease on the blades; (2) the blades can be lubricated very slightly by lightly marking on them with a pencil, leaving the graphite behind.  But the maximum tolerable amount of lubricant is less than you can see!

I've successfully restored old Minolta lens irises with DuPont Teflon dry lube: the solvent in it is excellent at removing all sorts of crud, and wiping it off afterward leaves just enough of the Teflon wax residue to keep the iris vanes lubed.  Then, lubing any mechanical parts that weren't originally greased with the same stuff, and greased parts with a good silicone grease turned some $10-for-the-whole-box garage sale junk back into fully functional quality glass.

FREE TO A GOOD HOME. JUST PAY POSTAGE. 

 

I got these 5" reflector parts as part of a "grab bag" a long time ago and have no use for them. Secondary (1.5")/spider is single unit all metal with three small adjustment screws on front side. Secondary mirror does have some scratches and blemishes on surface but may be ok for casual use.

 

Please PM me if interested.

 

Thanks,

Tony

I recently purchased a roll of HVAC aluminum duct tape that is 3.9 mils thick and has adhesive on one side.  I made three spacers for the Selsi 247 objective and have the rest of the roll left.  If you need an

inch or so to make spacers, send me a SASE and there is no cost.  Message me for my address. BTW it

worked for me.

Hi all… I’m putting together a second donation package for a new Ugandan astronomy club. I sent a scope to a guy a while back and he ended up founding an astronomy club that now has a few dozen members. A couple of members had scopes in dubious condition, so much of what I’m sending is to help get those operational. For example, sending a 2” to 1.25” adapter, some eyepieces, etc. 
 

I’m wondering if anyone has a spare finderscope… RACI or not. They have a standard shoe, so just the finder and a mount to fit into the shoe would do. 
 

Also, one of the new members wants to get her own scope… If anyone has a fairly compact scope (to minimize shipping costs, which are crazy high) they’d be willing to part with… That would save me some money as well. Refractor, collapsible Dob, SCT… anything smaller but usable… I’d be interested. And I guess a tripod that collapses down would be needed.

 

Please PM me if you have something to part with. Thank you.

I can’t edit my old message, but I’ll mention I did acquire everything and send off just yesterday to Uganda. Package was just a bit over spec size-wise, so wish me luck it’ll make it through.

I've mic'd several brands of the adhesive foil. It comes in between .0030 and .0035 fairly consistent and closer to .003".  It is about .006" with the paper backing.  I have one brand that is .002", and .005" with the backing.  It works. I have dozens of pictures of doing the Monolux 4384 with it. I've used it on other achros.   We use this for heat shielding on snowmobiles.

 

I custom did one shim to cover a double clam, then experimented with Unitron look-a-likes and other shapes. These are the 4384. Sorry I don't keep my strings up to date, this was a long time ago.

I have the polar scope from what I believe is an EQ3 mount.   Looks average but optically perfect.  Let me know if you want it and I will send it to you.

 

I also have most of the mount head and the aluminum legs.  No counterweight bar and no weights.  If you want that you can pay the shipping and I will send it to you.

 

I also have this weird eyepiece holder.  It came from a Meade 4.5" reflector and screws into the cheap focuser.  Holds 1.25" eyepieces.  I had never seen it before so I held on to it.  Maybe it is something someone needs. 

 I had a use for some of these items. What a deal. They were delivered promptly

and very well packaged.  I believe the polar scope is original to the mount head,

as it looks correct and fits perfectly. 

 

"If you want that you can pay the shipping and I will send it to you."

 

 Yeah right! I did inquire about the S&H. He covered it ALL! Totally unexpected.

DRMILSPEC gets my vote for SCOPE-DUDE of the month. With apologies to any

SCOPE-DUDETTES who may be competing. It was a TRIFECTA of WOW'S so...

thanks, many thanks and THANKS AGAIN!!!

                             Thanks 2.gif

I have a very basic altazimuth head. Not sure of the origin, maybe Jaegers? Made to take three wooden dowel legs.

Free for the cost of shipping or pick up in Westchester County,  NY.

I'm remiss on my manners here, they arrived a day or two ago and they are as nice as the pictures look. I have hopes they will make a fine pair for bino viewing. Thank you!

I've seen those in two different styles, a round knob and a tri-lobed knob. The size and pitch is 5/16" x 18 (5/16" diameter, 18 threads per inch).

I have two EQ1 mounts (one Celestron, one Meade). They both came with came with 114/F900 reflectors.

Both are in good condition, but don't have counter weights. I probably have 1 slo-mo cable for each of them.

Free for the cost of shipping. Please let me know your zip and I will give you a shipping quote. I use ShipStation and their UPS rates are very low.

 

Here is the picture of the Celestron one.

Next post shows the picture of the Meade one.

 

 

I have tripods too. if you really want them I can ship them too but shipping could be more.

The Celestron one is almost new - probably used just once.

The Meade looks a lot more used but it is more robust/bigger than the Celestron one.

Your choice or take both!

That "boat"-ugly Meade mount is surprisingly good in use. I forgot how I inherited one, but it's living with my newbie friend and she loves it. it works perfectly.

I have a pdf of a Celestron 1998 accessory Catalog. 36 pages with color pics, It has the original Ultima line of eyepieces, to give you idea of the era. The 2" 50mm Ultima is not in it. The pdf is 1.5 MB

I'm to email people a copy, but if there is an on-line library to post things that would mean I only need to it once. If you know of such a web site, let me know. Or send me a PM.

Last time I checked, it is about Cloudynights does not support posting any documents that large.

I reserve the right to end this project if I get hundreds of requests.

There is no 2" 50mm Ultima eyepiece in the original Ultima series that came in the orange striped box.  There might have been a 50mm Axiom, I'm not sure. The Axiom series came out after the Ultima and supposedly has the same optical design.  The original Ultima line has three 2" eyepieces, 45mm, 60mm, and 80mm. I have all the original Ultimas, missing only an original box for the 60mm.  I only have one Axiom 19mm but I'm not collecting the series. The Ultimas have a good enough distribution of focal lengths for me. 

 

Anybody have an original box for a 60mm Ultima?
