Long white tube refractors get a lot of press, so here's a place to post why you like reflectors.  I was late to this party, but I'm grateful a guy in B'ham sold me his Dad's 1971 Criterion RV-6 Dynascope, and opened up a whole new set of great views!

I inherited CHAS's 1980s Meade 826 OTA through a middle-man:

Absolutely the best deal in a used scope -- and I've bought quite a few!

Last, but not least, is Stubby -- my 1970s (?) ATM / Edmund 6" F4 Newtonian RFT

It has to be one of the easiest to use Newts.  Last night I swept the full length of the Milky Way, while sitting comfortably in a lawn chair -- most of the time looking down into the eyepiece.  No strain, no muss, no fuss -- and another $100 vintage wonder-scope.

I like reflectors because they are economically feasible for using LARGE aperture.

Nice to see the RV-6 scopes again. I enjoyed the ones I had some years ago, but upgraded to the Deluxe series since and glad I did.  Finally working on some Deluxe scopes (8" & 6") now.  They  look more "Professional" (my opinion) and have a better/more solid mount.  

 

Still recall  the first day going into the Church Street factory as a kid.  My father thought we were "not there" and wanted to leave !

It's a 1980s Mizar AR-1 on an original Short Pod.  It'll carry my RV-6, too -- but NOT the 826 (yeah, I tried!).

 

I also have a Mizar Super Polaris -- looks very similar to the AR-1.  I found an MDS II drive system for the SP, and I'm hunting for one for the AR-1; so, as of now, it's a manual tracking EQ.

 

Beats most any Newt made today for under $400.

 

I agree, and that 1st RV-6 started my Newt Buying.  You can get them so dang cheap!  That's a problem.  The way I am, when I see that a scope has great potential, I just have improve it.  All 3 Newts got upgraded focusers, right angle finders, etc., etc.  Better than original mounts.  And, I'm still improving that RV-6...

Functionally, it's done.  But... it'll get end rings, and some kind of exterior paint / refinish.  By then, it'll be re-coat the mirrors time.  And, then...

My first purchase in 1974.....a Edmund Space Challenger VI 6" on the extra heavy duty mount.  This was Edmunds first production scope designed for Astrophotography.  I restored it in 2014.  Logged a lot of hours under the skies for several years with this one.  It was housed in a roll off shed observatory and it deserves a new shed.  

 

Cheers

Bob,

Glad you started this thread. Some beautiful classic Newtonian's already posted here. I'm a super fan of the RV6 even tho I sold mine to Chas recently. No need to go over the RV6 strengths and weaknesses  it's been covered before. But for nostalgic reasons let me say my early 60's RV6 was a dream come true for me as a 12 year old boy. I got my picture with it posted in the Dallas Times Herald with a nice write up. Soon  after I and an older teen  were plotting Asteroids on my Skalnate Pleso large scale maps. From there until a few years ago I've used it for thousands of hours for fantastic views, of DSO's, planets and one of my favorite double star telescopes.

Nice thread, Bill

That is a mount all 6" scopes should have came with.

 The RV-6 was not my "lust scope" as a kid, but after recently acquiring a couple of them I see why folks praise them.   OK, their mounts aren't rock solid and the motions can be backlashy if balance is off, but considering that you can easily grab the entire EQ head with shaft and counterweight attached, and keep the legs on the pier when packing into it the SUV makes setup and break down quick and easy.   Plus it has tracking and enough aperture to really see things.  They have replaced my ATM 8" dob as the default scope.

I'm not sure that "all" should have come with such a mount because of cost. The RV6 at $200 was a very big expense for me at the time. I could not afford anything more expensive. But to agree with Chas a quality mount like the Edmund VI 6 and the Cave mounts for their 6 inch scopes  truly make the 6 inch f/8 a more professional product.  Also as a kid I had no problem with the RV6 mount and the play in the drive. I easily overcame those things and felt it was easy to use. But in my later years I was no longer so skillful and found the mount to be a pain. I'd love to  have a quality 6 inch f/8 Newt on a quality equitorial mount. Pretty hard to find one tho. But if I saw one for sale I'd be interested.

Bill

Your RV6 on my AP800 was rock solid.

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.

Over time my 1981 ATM 6" F/8 has evolved and old components replaced as new/better one became available.  

Now days seem to be using my older 1973 4" F/11 more because it is truly a grab & go scope.

I'm very happy with my Meade 826, but it would still be nice to have an all-original vintage Cave 8" F7 kit -- just like Jim Vice's.  Meanwhile, I suppose my Cassegrains count as reflectors, right??

The 235 lb Tinsley 6" F20 kit is now on display in my man cave.  The first version of my Edmund (3B) 4" F15 is gone -- I kept only the mirrors & helical focuser.  When I get time, it's getting a real spider & secondary holder, seamless aluminum tube, and decent back-plate.  Turned out it was too complicated for our grandkids -- bless their hearts for trying another of Pawpaw's hand-crafted scopes.

I just received this Beautiful Astroscan 2001 Telescope as an 85th birthday present from my son.  What a great gift.  I haven’t owned a scope for decades.

This is my ATM 4" F/10 Newtonian. 

The mount was built in 1973 by a hobby machinist friend of my grandfather and the OTA is a recent build using a NOS 4" mirror.

Somehow this post disappeared from this thread so I’ll post it again.

 

Here’s the reflector I made in 1967 (6” F4.5), still going strong after 53 years. I used an Edmund mirror grinding kit and Thompson’s book. I ground and attempted to parabolize the mirror, Cave Optical refigured it and Pancro coated it. The original coatings still look great. I had the galvanized, rolled and seemed tube made at our local sheet metal fabricators that summer. The cast aluminum cell, brass diagonal spider, and focuser were from Jaegers. (The secondary mirror came from Cave when they refigured and coated the primary.) I purchased the mount from Edmund using lawn watering, baby sitting, and pet care money. I got the tube powder-coated about twenty-five years ago, flocked the inside of the tube with protostar flockboard four years ago, and rebuilt the mount/pedestal three years ago. I last used it six weeks ago to view Comet Neowise and it still works great!
