My Newtee Cutie!  It began as a China-made Celestron PowerSeeker 114AZ; by the time I finish replacing parts, it'll be a vintage Celestron/Vixen C4.5 with a Chinese tube.  The mount is a Vixen Polaris on a 1960s Eagle surveyor tripod.  Very stable platform!

the C4.5 Celestron/Vixen with Polaris mount w/wood tripod was my first real scope, I sold it to a friend about 5 years ago and it is still in service!  coatings are good and the mount still works like the day I bought it.  nice to see a blast from the past, even if it isn't exactly the same.  the original tubes were notorious for losing paint off the tube when you rotate it in the rings.

My first real telescope.  6 years ago I bought this OTA off of a friend.  It gives wonderful images.  I think this weekend I will take it for a spin!  Here I have it mounted on my Twilight I mount, which makes for a perfect little grab & go setup!

I'm very pleased with my C4.5's views on all object types.  It's so light!  And it takes just a few minutes to temp adapt.  It's my grab & go reflector.  On DSOs, it compares well with my Jaegers 4" F5 refractor; lunar & planetary are neck & neck with my 3" refractors; on double stars, my refractors have the edge in resolution, but the reflector gives more natural colors.

I'll never forget the first deep space object I ever saw with this telescope.  The Orion Nebula.  I think I stared at it for half an hour!  I love studying the moon with this scope as well.

OMG I love that mount!!  That would be perfect for my LB!  Maybe a bit of a effort to cart around but I want it!

This is my 16" set up for imaging.  All home made except for the optics. 

 

My avatar shows the 22".  Also home made.

I don't really have any build pix since I built the mount about 15 years ago and didn't know about Cloudy Nights at the time. Were they even around then?  I have some pictures of assembling the finished parts and one picture of a modification to the mirror cell.

 

The mount was originally push-to using a tangent arm for Dec, a CAT for DSCs, and a home made drive corrector with a plug for autoguiding.  About 4 or 5 years ago I contverted it to Goto using a SiTech servo controller.

 

Here is a picture of the mirror cell from its first outing and the picture of a modification to the mirror cell.

My flocked and blackened Synta 6" f/5 on a modified and motorised Celestron CG-4...

The Newtonian is quite good for being mass-produced; above average I'd say, and from what I've seen with it.  It's only real drawback is its plastic focusser, but I'll have that taken care of in the near future, and with this...

 

Parks 1.25 focusser7.jpg

 

I even have a shorter visual-back for it, and to ensure the focal compatibility of all of my oculars.  Once it's installed, I may then obsess over the collimation and perfect it.

 

I also have this Parks 8" f/5, but as to whether or not it will ever see the lights of night, that's up in the air...

Here's my 6" F4.5 RFT. I made it 50 years ago this year. from an Edmund mirror grinding kit. Cave refigured the optics and had it 'silvered' and coated by Pancro. It made its first trip to Stellafane this summer.

Terra,

Wow, you must be very smart: You made a complete 6 inch RFT when you were only two years old :) !

 

 It made its first trip to Stellafane this summer.

I don't think we had the opportunity to meet. I had that little 8 inch ball scope that was completely invisible, overshadowed by the two beautiful refractors on Breezy Hill.

I just had my scope in the lower field/camping area rather than up on the hill. We got their Thursday and camped but didn't make it up on the hill until Saturday afternoon after that brief shower. Sadly all the scopes had been either taken down or covered up. We love Stellafane and will be there again next year.

 

(PS, I was 16 when I made the scope but thank you for the comp.)

I like that OTA. Nice and compact.

Thank you Chas :)

At age 15 i placed a order on a 6" RFT from Star or Sky instruments back in 1978.  Scope took much longer to ship than what they said and then it came with the 2ndary loose and chipped the main mirror. So back it had to go.

Mirror was held in place by a center bolt.

They did.  I used it on a Edmund 1" mount.

My first newt build. It's not quite right yet. I've put it on the back burner for now. Need to think some things through.

 I hope to mount it on a low profile GEM so I can sit while observing (like my refractor). 

10"f6. Did I mention it was blue.

Here's my vintage Celestron (Vixen/Japan) C4.5 (114mm x 900mm, F8) on its Vixen Polaris mount. Sharp images with great contrast in a fairly small package! It's perfect for viewing on the deck.

A nice one,Terra.  Brings back old memories for sure.  Sold mine a few years ago and it's still seeing regular use.
