HSource was the closed down shop of Pegasus optics. 

6” F4ish?

7-3/8” diameter tube

30” long ota

Aluminum rings (thin)

fiberglass tube

 

With the primary mirror moved towards the secondary (2 sets of mounting holes)

lunar views were very nice using a DS16C SkyRaider camera. 

 

Any ideas who who made the scope?

 

Thanks in advance for all ideas!

It looks like a research grade Meade.

It looks like a research grade Meade.

Meade never made a RG 6". Or any F/4 Newt that i know of back in them days.  Not a Star instruments like i had in 1978 as mine had a center bolt that held the main mirror to the cell. Could be a home made deal. Not sure on the tube, take a sniff inside and you should know if it is a Parks tube.  Parks have the strong fiberglass smell like no other tube does. If the tube is very smooth on the inside could be a Meade Fiberlite tube. End rings look like Meade.

So no more news on this scope?

Looks like a Cave RFT

[MDearingJaxFL]

Did Cave ever use different looking primary cells like this ota has on the Cave 6” RFT?

End rings are wrong for a Cave. Send it my way when you get tired of it.

Looks like a Cave fiberglass tube with Novak components to me.

Cave got their tubes from a few places and even the Meade Fiberlite tubes near the end.

[The Planetman]

Could be a Telescopics. They made RFT's using the helical focuser. 78 to 83-ish era

[scopewizard]

I said Meade because a friend of mine in the 1990 had the exact same style of tube and end rings. The mirror was 12.5" Meade which he still use in a new fiberglass tube.

The focuser was replaced.

It looks like a two inch focuser and I’m pretty sure the Cave RFTs had a 1.25”.

I have the same helical focuser on one of my homemade scopes. It's a piece of junk and it's very difficult to get a good focus using it. I don't think any commercial telescope company would put this focuser on their scopes.

 

The OTA looks like a put together job ... IMHO.

[MDearingJaxFL]

Ross, enjoyed the connect to Telescopics!

 

Terra, is the 1.25” finder you mentioned mounted with 3 screws?

 

Skyguy, you are correct about the poor performance of this style of 2” helical focuser. 

 

To all; this focuser has 4 mounting screws and there is no sign of any other mounting holes from the past (3?).

I don’t remember. It’s been a number of years since I’ve seen one close up.

[CHASLX200]

That looks like the late 1950's version with the rounded end rings. I don't even think Cave made any 6" RFT's in the later 70's.

[MDearingJaxFL]

Terra,

 

Were you possibly thinking about the 1.25” Sky Micro focuser (fine threaded helical on top with 

R/P on the draw tube)? There is also a 1.25” Sky Micro helical version also advertised in the Telescopics catalogue.

No markings on the mirror? Cave most times had a date and such on the back or edge.

I’m thinking of the one in the picture I posted. 

[Joe Bergeron]

Definitely a Novak cell. I’m thinking this was assembled from various parts by someone, not a commercial scope. I used to do the same thing.
