Someone pocketed my Questar (3.5) eyepiece and adapter ring! I'm hoping someone has the adapter I have highlighted in a photo. Please let me know if you have one available . Thank you, Don

I am looking for a criterion 1" drive. I need the worm block, worm wheel and clutch for a 1" shaft. I will trade my Jeagers 1" drive straight up if you like! It's for a neat project....

Oh man! Well that seems like something a machinist could make with a decent lathe.

It's the white phone for Edmund.

 

No, it's the red phone for Edmund. The white phone is for Unitron.

Let's stop talking about the phones. I know you've been using a Criterion lately."

Looking for an old 0.965" eyepiece sun filter.  Yes, I know the risk.  I need it for the finder on my Questar.  Thanks.

Greetings    I have the nice  Pentax  75edhf    somehow  the extremely small screw that goes on the focuser  has slipped out in the driveway and is gone.  Now the focuser knobs work fine but only the little black tongue moves in and out but  the focuser does not...

 

Seems like small eyeglass screw size but who knows    any ideas?

Thanks in advance

Is there one on the other end of the rack you can match it to?

Could you gain access to a "roofer's magnet" to sweep the area. I use a wide magnet removed from an office copy machine years ago. Works good if I'm not looking in thick grass or the piece is imbedded in the surface.

Chances are it's a brass screw.

 

Those screws are of course very short so they don't protrude through the drawtube. But I'm sure a standard 2mm or 3mm screw will work. I would raid my old computer parts for a screw. Disk drives have lots of small screws.

I decided to go on a whim and buy a potential basketcase, mainly for the mount and drive, but does anyone know or have a Celestron 8" secondary and corrector plate laying around you aren't using?

I do have a late 70's Orange tube C-8 OTA in need of a mount.  I might use it on this mount if it proves to be functioning. . . .

Looking for a finder mount for an orange tube C8 that will handle a 50mm finder.  If it comes with a working finder - so much the better!

Hello all, I'm in the final stages of refurbishing an orange tube Celestron Comet Catcher and I am missing the dust cap that fits over the end of the scope where the corrector plate is. A 5.5in scope cover is hard to find so far... Thanks and clear skies!

Anyone have a spare power cord for my newly acquired Celestron Byers C-8 mount?  It's a 3 pin socket . . . . . .

Looking for Vixen MD-5 or MD-6 controllers.  That are complete and thought to be operational.

 

Thanks!
