Nice find Stew, those edmunds look similar to what was included  with this Carton in a pouch. (Well one does)

Thanks Walter,

 

The Edmund are 1/2" and 1-1/8" fl, so 12.5mm and 28.5mm.

 

The 40mmK is complete.  But later versions have the flared end ring and a field stop.   Those parts may still be missing, but will see how this couples to other earlier Goto focusers when they arrive.

The Carton 8mm Plossl is unique, I've not seen it branded as anything else.

Hopefully this has optics. If not, I didn’t pay that much and I’ve got a 6” f6 Edmund and wouldn’t mind a nice rigid tube already cut for a 2” focuser.

The Mizar 60/1000 from Zen / YAJ came in 03/30. Unboxed yesterday with Gandalf's help.

   Tight - no slop. None. Gandalf has removed upper and some end bubble.

He likes popping it. a lot.
1280 IMG 0461
   Original, glorius Mizar box. Stood box on end and
held top while Gandalf spun the Saran wrap off it - no lie.
1280 IMG 0466
   Let's get to the scope, old man!
1280 IMG 0469
   Everything thing was bubbled and tight - no slop.
1280 IMG 0480
   Set the legs long - they're in fine condition, just need an oil wipe.
1280 IMG 0483
   Mount is smooth and older grease provides very nice stiction. Dual TA. Needs minor cleaning.
 
Got up early for the Moon Test, Star Test. Stayed on moon. This Mizar is giving the Crescent 60/910 serious competition. It may lag a hair on contrast, we'll do a side-by and see, but they are both wonderful - they have beaten every other long 60 achro on contrast/sharpness/clarity and we have many (including the 'besties'). The included EPs (20 & 8) were clean and gave good views. Borrowed the diag, a 12.5, 9, 6, 4mm from Crescent's kit - bang on. Will try a Tasco 8~18mm Zoom next outing. Star Test tonight should hold no surprises.
 
~$50 scope, $209 delivered. Had no strong idea how it would perform. I am pleased - didn't have one of these. Overall very nice build. VB is a one screw, boohoo. Mount is simple and although I thought I preferred dual 360°s, I really like this simple TA  AltAz. Tripod is stable, slo-mos nicely short - no settle time - no breeze, so... 
 
Maybe some fuzzies tonight - have some old Meade .965 40mm EPs to keep the mag to 25x. Should try a hybrid diag next and a few 1.25 eps.

That is a really lovely and distinctive 60mm! It reminds me of the Goto HyScore 60mm I used to have. Congratulations!

I think I have found two long 60 keepers - I can even use the finder on the Mizar left eye - plenty of offset. Whole setup is featherlight - wide & stable, but light. Skies are hazy (orangy last night) and the moon washed out during a hoped 'blue session' just now, so still not sure of the actual contrast - but seems very close.

 

waytogo.gif A 451 is on the list - another very simple looking setup with great reviews. I claim not to be a 60s fan, but set these 60s at chair height and cruise the moon - hours of immersive with good eps.

 

FWIW - I think you are at a good place with your take on scopes & astronomizing in general - it makes sense, it's focused but not harsh.

The MN66 came in today. It’s the first version with grey pebble finish paint and six small vent holes. The seller had won a storage unit auction and had no idea what it was. It was listed as Maskutov(sic) Newtonian 6” f6 Made in Russia, in the paintball accessories category, BIN for an extremely good price. I didn’t find it through a search on Ebay itself. I was actually looking for user reports on Mak Newts to see what people thought about the GM8 and it’s capability to handle a 5 to 7” scope. When I searched for Russian Maksutov Newtonian, it showed up in the ad bar in Google.

 
The ad had no pictures of the optics and the tube was oriented in the box in a way where I couldn’t see the focuser or finder brackets. I sent a message requesting more pictures, thought about it for half an hour, then bought it before I got a response. The seller had used the Used - Fully function condition tag and I added a detailed message requesting pictures of specific parts, described how it should be packed, and asked that they contact me prior to shipping and purchasing packaging if there were broken glass or no optical components. I explained that the corrector is extremely fragile and often breaks in shipping when not packaged correctly and that I would like to have pictures showing it to be in good condition and well packed should the shipper destroy it. I got a couple of status updates regarding shipping but no pictures or even acknowledgement that I had requested them and was considering requesting a cancellation. They did finally send a picture of the corrector taken as it was being packaged.

 

It did end up coming double boxed, fortunately, since the original was not meant to be shipped without further packaging. Unfortunately they only used a thin sheet of bubble wrap at each end and a smattering of packing peanuts. When I laid the box down to cut it open, I heard tinkling and started cringing. The box only opened at the ends, so I had to orient it vertically and slide the outer box off. When I did so, I heard a rattle and a thunk and thought for sure the secondary and fallen down onto the primary. When I got the tube out and the dust cap off, I saw what looked to be a 2 to 3 inch long, half inch wide chip at the edge of the primary and a metal piece near the center spot.

 

Miraculously the chip turned out to be two packing peanuts that had been pushed inside the tube through the open focuser. The metal piece turned out to be one of the corrector retaining clips and, along with its two screws, the source of the ugly sounds I had heard. I then gently removed the corrector cell and found that the corrector had been dislodged and nearly fell out of its cell. I got it reseated and the clip reinstalled, blew off the loose dust on the corrector and primary and reinstalled the cells - it’s definitely nice that the tube has an indexing bar to ensure correct alignment during reassembly. Despite everything that could have gone wrong, the only damages sustained are a fine scratch on the inner surface of the corrector, a small scratch on the secondary, and a few small surface scuffs on the primary. The mirror and corrector coatings all look really good with relatively minor dust accumulation. It even looks, by eyeball at least, to still be in good collimation.  
 

My old 628 and RV6 rings are just a bit too small, so it will be a little while before I can get it up and running, but I think it will be worth the wait.

That was exciting and I am very glad things turned out okay. Packing peanuts get in everywhere - like ants - especially when you have to disassemble to remove them - the little buggers know.  Most non-AA sellers seem to be just annoyed as heck with our silly shipping and packing requests - and it's our dimes. Meh! We're often better off talking to our shoes.

 

You've done well; Urania has smiled upon you! waytogo.gif

I’m happy for you. A good Mak Newt is a wonderful thing, and Intes made the best. They’re pretty darned close to a fine Apo refractor of similar aperture. You should have fun with the up company planet season. I always had a hankering for an MN56. Came close to getting one a couple of times but never pulled it off. Enjoy! waytogo.gif waytogo.gif

Just bought a Vixen "Custom 90-M" today for $40.  I've only seen photos and it look like it will need some work.  Main concern I have is the front optic - any idea of what I may be running into here regarding restoration and I'd like to use the scope for moon/planet observing.  Thanks for your help/suggestions!

Nice find!  I can't see anything outwardly wrong with the front optic from that photo, it looks clean.  But I'd need to see more images.

I did a zoom on the objective but the reflection is so "busy" it's hard to see what's reflection and what may be on the surface. Try removing the cell from the OTA and take a pic with a blank white wall/paper as a background.

 

Not sure but may be, Clam bottom left, fungus bottom right, scratch middle right? just guessing, so hard to see through the reflection. click the pic for larger image.

This lens do not look like fungus; but delamination. Maybe suffered a side hit.
I saved a few binoculars by dipping the lenses in water and heating them until they took off. It also helps to dip them in solvent.
After cleaning them, I reattached them with Baby Johnson oil and taped them with scotch tape. A friend uses -with great success- a transparent silicone grease that is used in the differentials of RC race cars.
Try to make a mark (if you do not have one from the factory) to maintain the alignment of both glasses when reassembling the lens. So you can recover that excellent telescope with an arrangement that is fully reversible. Something that is not possible with adhesives for UV light, or synthetic resins.
Regards.
Edgardo
Painting the edges with black fiber greatly increases the contrast.

Errrm,,,,, It's an air spaced objective....

 

What i thought was a clam still looks like a clam, shouldn't be a problem as for most observing it'll be in the outer 20% ish' of view. the rest should clean up nicely albeit with some coating loss which isn't that important. Most of what looks bad will wash off, the four noticeable black dots may have etched but you won't know til it's clean.

 

Let the lenses sit in some lukewarm water with a touch of dish soap, dont rub them!!! rinse with clean water. There's a ton of info on the internet on lens cleaning so good luck :)

Yes, I'm getting it - got to figure out what to do for rings. Seems those don't show up often.

 

Should be fun to play around with. Keeping either it or the RV6 for outreach, one has to go.
