My Edmund 'Astrostick' yes that's a coffee can.

6 inch f/5 Edmund primary, Edmund focuser, diagonal flat, and zenith prism.

Daytime is really excellent, you wouldn't think so without a tube but it is.

Nightime is breathtaking, fabulous optics, no tube currents, quick equalization.

Right now it's in the Sam Brown Bazooka configuration, remove the zenith prism

for astronomy.

Two friends who had come along to help me more a Cave 12.5” /7.7 with 6” f/12 guide scope I won at auction. Planned to set it up in Oregon but bought a second Observatory Cave and decided to use it instead. Sold this one before ever having a chance to use it. Went to a great guy fortunately.

Celestron Pacific C10 with C4 guide scope. Another classic, now gone. Posting these pictures reminds me how many wonderful instruments I have had the privilege to use before passing them along....

Coast Instruments 8” f/8 Trekkerscope. At the time I lived in Long Beach and after a bit of research to find an address I took the scope to the building which was Coast Instruments shop back in the day.

That's a very cool photo. It looks like it's on film so you probably did it quite a while ago. I live near Celestron and was thinking of doing the same thing. 

 

BTW, I really like the look of those mounts and how they are integrated to the pier.

Nice thread!
This is the first telescope I have purchased on the very first money I have earned working hard (gardening public orchards smile.gif ).
~1982, USSR, NPZ (now TAL) "Alkor" 65mm Newt on Alt/Az pier (the image is not mine, I have both my classic Newts gifted to local youth clubs when moved to the US in 1999).
The box was extremely convenient to keep all my other astronomy gear in it organized and portable on a short notice.

teleskop-alkor-sssr,medium_large.1600478

 

And my second Newt purchased in early 90es, now Russian 110mm "Mizar" TAL-M1 (same NPZ factory) on the very nicely performing motorized GEM (stock image, can't find the M1 model live anywhere):

tal-800x800.jpg

 

Both are "weapon-grade" cast aluminum :) 

To be honest, not really a fan of the classic Newts on a GEM or any other EQ mount. The EP is always in a wrong position, so have to use rings to rotate it like for every object (today you can use an observations planner app to limit that, but in the past it was not that simple).

HI Kasmos,

 

Yes, I did use a film camera to take the picture, probably in the late 90s Before I took the digital camera plunge. The building was a drug rehab center by then if I recall correctly. 
 

The Trekkerscope was a blend of industrial art and function. I wish I knew who designed the mount. Mine was outstanding optically and I thoroughly enjoyed using it. 
 

Lew Chilton is the expert on Trekkers, hopefully he will read this and add a little insight into the design.

Beats most any Newt made today for under $400.

It was about $200 in the mid-1970's which would make it cost $1000 today.  For $1000, you can get a metal goto mount and a six-inch OTA I think.

I have owned several RV-6s and gave most away to friends with kids. Just cobbled another one together from a bunch of parts and had it out a couple of nights ago. Not all original but darn close (optics are original). Wonderful images! Pictured with a special order Cave 12.75” made for Dr Henry Paul I just restored. I missed buying the original mount so picked up a Schaefer in its place.

From the "Blue Heaven" observatory?

I know someone who had a Tal.  He changed the tube to something lighter, I used the thick-wall tube to make a 5 inch refractor I still have.

Sure is mounted high for a Newt. Love to have it but my back says no way.

Here is an ANRA/Optical Craftsmen 6" F8 from circa 1964.  The optics appear to be outstanding.  The instrument has some ANRA markings on it, but I don't know if that was part of a restoration effort or original.  The finder has a thick stalk in lieu of crosshairs.  I would love to hear from some experts here as to whether that is original.

 

The photos of Jupiter and Saturn were taken last week at prime focus with a ZWO ASI224MC.
