Lots of classic astro stuff out there. Scopes, eyepieces, prisms, finders, adapters. The list goes on and on. But then there is the unusual and folks may not know about it. Take the Celestron Williams Dry Ice Cold Camera. Remember that? I was hoping to utilize one of those back in the 80´s. To no avail. It was ridiculous. Total disappointment for a young chap who had spent a years worth of paper route money. Not everything bad, though. Tuthill a harbinger of some pretty well thought and innovative astro gear. Think isostatic mount. Hope this will be fun. So here we go with the first entry, a set of Zeiss filters:

It has taken me a while to get hold of these Zeiss filters. They rarely come up on the bay and I thought it a great idea to watch the Mars opposition in style with the 80´s Zeiss Marsglas. It screws on any Zeiss .0965" eyepiece by unscrewing the universal plastic ring on the top. The orange glas is an OG5. Using it on my Zeiss Telementor, dark surface detail on Mars is visibly enhanced. Most any OG5 filter will do the job at a fraction of the cost. But then these are not Zeiss! Same goes for the two pairs of beautifully machined Zeiss Mondglas hell and Zeiss Mondglas dunkel (moonfilter bright and dark). I tried them both on a half moon and they do a great job. Modern variable polarising filters offering more convenience, though.

 

I hope this can be a fun thread. So chime in and show us your quirky astro stuff from decades past.

Stefan,

This will be a fun thread with no end in site...........Here is a over engineered Edmund off axis guider developed circa 1979.  This one came with a 8 inch relfector model 4001 I purchased back in 2003 but was never mounted on the OTA.  I still marvel at the sand cast engineering and finishing.  Instead of re-inventing the wheel here is a link to a very detailed post by Amicus Sidera (in memorium) that shows everything you need to know about this extinct dinosaur from the early years of amateur astro-photography.

If the Edmund 1.25” 28mm RKE is touted as the Spacewalk Eyepiece, it feels more like the spacewalking astronaut has become untethered and is drifting in endless space while looking through this baby! Edmund sold these heavy brass encased gunsight eyepieces from WWII in their catalog more than fifty years ago. Approximately 2” in diameter and weighing about a pound, this Spaceship Porthole is an old favorite of mine. I bought my first one fifty-three years ago and after years of begging and haranguing, I finally let my brother have it some twenty years ago, whilst wooed by some of he new designs. I never got over that and after looking for some time, I placed a want ad here on CN. Through the generosity of a CN member here and my undying gratitude, I finally have another.

Lafayette Tele-Cam camera adapter. It actually works pretty well with a light camera.

How 'bout the non-deluxe Optica b/c 1.25" spectroscope.  Works great on the Sun.

Goto Kogaku terrestrial erector.  This is Goto's first model prior to the compact poro prism.

Another weird (& LONG) erecting lens assembly -- this one from that 1956 Space Scope 151 that I bought locally:

 

Space Scope 151 - S23.jpg

 

To Use:  Remove the .965" eyepiece adapter, then thread this in.  It came with that very good Zoom Kellner that uses a BB as a click-stock.  The scope is sold, but I kept what turned out to be my very best 1950s Kellner -- 30mm when compressed.  With 50mm & smaller refractors, it gives me that 3D Marble Moon view.

Probably one of the oddest mounts I've come across.  If you have it in alt-az mode, you only have access to about 30 deg above the horizon.  If you tilt the latitude adjuster to put it into EQ mode, you have no sky access except for about 20 deg. above and below the ecliptic.  Perhaps it was meant as a mount for lunar and planetary use only.

 

It holds a 60mm scope in its captive clamshell.

Mondglas on dude. What's the hell?

I should do something with this one. Mine is a slightly different version, two bolt mount. 

 

Here is the one that hits the most non standard things in the most places I've seen.  The electronics, mount, focuser, total toaster knob job, it works, apo, Springfield - semi, 8"  F(out there 7 or 8 or more...), more.

Here's more

Part of the focuser and upper half mount.

Very strange prism finder on Nippon Kogaku 50mm scope. It's just like the prism finder found on old folding cameras.  It give a right angle view of the two peep sight finder tabs.  It has to be aligned every time you change eyepieces, as it attaches to the eyepiece barrel and must align with those tabs.  It does work, but it's a pain to use and not particularly effective.  Fortunately, my NK50 came with the optional finder scope.

Another contraption from the golden times of analog. German advertising blasted this shiny marvel of ingenuity in the late 80´s, promising dramatically increased film sensitivity for long exposure astrophotography. At less then a grand I happily boarded the train. Just a few easy steps had to be followed: Step one: Lights off. Pull out film from canister in darkness. Step two: Insert film on special spool inside the cylindric pressure chamber. Step three: Close chamber lid and fasten with wingbuttons provided. Step four: Lights on. Attach pump to valve and suck out air. Step five: Close valve. Step six: Attach canister with forming gas and hydrogen at opposite valves. Step seven: Open valves. Step eight: Close valves and let forming gas do its thing for 10 hours. Step nine: Open valves to let gas escape. Step ten: Lights off and open pressure chamber. Step eleven: Remove film and roll back into canister in complete darkness. Step twelve: Lights on. Step thirteen: You are now ready for some great astrophotography. Step fourteen: Develop exposed film. Step fifteen: Realise M42 is a blurry soup. Step sixteen: You black out. Step seventeen: You wake up in an institution for the very nervous.bangbang.gif

Image Rotator.jpg This attachment if from my 1960 12" Fecker cassegrain. As you rotate the brass part, the image through the eyepiece rotates. I do not really understand why anyone would want that.

I bought this Tuthill device in 1986. Didn´t utilize the polar axis finder. Loved the "Ring-Of-Fire self-illuminated eyepiece", though.

Gotta love those quirky mobile car observatories. Jeff Schroeder´s "golden" frac on top a matching classic Volvo.

Found this little gem in my brochures collection. Polish startup. Never saw one of these in flesh, though.

One of my favorite "oddballs".  An Optica b/c adapter that is threaded for a T-mount on one end, and is a diagonal/eyepiece receiver on the other.  Instant telescope from you favorite T-mount camera lens - in theory, anyway.  It only works with a diagonal if you have a very wide focus range lens, like one of the old 500mm mirror lenses.  It works with all lenses if you view straight through with just the eyepiece.
