Recently I bought a Meade 2044 tube (it had the single form arm bracket) that was inexplicably and unexpectedly missing the primary mirror. Just as I was considering throwing the thing out or scrapping it for parts Bill Vorce listed a 107D spotter here on CN with a broken optical window.


The 107D and the 204x series of SCTs share identical components except for the secondary and front plate. On the 107D the front plate is a flat optical window and the secondary has a Mangin corrector - the 204x scopes, being SCTs, have a Schmidt corrector and a slightly aspheric secondary.


Since the primary in both scopes should be a perfect 4" f/2 sphere and the secondary is supposed to be hand-figured to match the corrector, I figure the image has a pretty good shot at being decent, and I've spent almost nothing on this little scope to begin with. Just needs a finder bracket (already have the original finder) and a tripod mounting plate.






Do I really need it when I have an ETX and 4" tabletop Dob? Nah, not really. But I'm really glad that I managed to salvage two ruined scopes and make something useful. Maybe something great. Who knows.

That's a great find and a second life for such a good 4" scope. Let us know how the "new" scope comes through. 


Clear Skies!

 Saving two scopes from the landfill = awesome


  Finding new home for the rescued scope 

   for someone who wants/needs it = priceless

Coolness! I have 3 2045s (LX, LX3, and a spotter) and a 107D and they make fine little scopes once the colimation is zeroed in. It's fantastic that you were able to salvage a 2044.

Neat stuff!

Didn't see this before I posted to your other post about this scope.  


I wonder, though, if Mizar figured the secondary to match the other components like Celestron alleges they did.  Meade didn't do anything but package and sell the 4" ers.
