Here's my 250px at Kielder. I never try and modify things because I will just break it.  Been thinking about a much bigger scope for several years but something always gets in the way. If I do go bigger I will still keep the 10", a very handy scope.

Here is my latest acquisition.  A Celestron Starhopper 12.  Mirror was recoated by Normand Fullum not too long ago.  It is a very sharp mirror.

Major issue was the azimuth control.  The roller bearing on the sheet metal offered little to no friction which made controlling the dob hard, and very noisy.

I did away with the sheet metal and used 2 pieces are hard cardboard from a box that a vacuum came in.  Much better and super smooth.

The stock focuser was fine, but I put on a moonlite on it.

I have added the Astrozap Dew shield to my 200p I find it really helped with lateral light intrusion.

Yes they are very useful. At home it cuts out the light and at star parties helps with dew.

My first dob was a 10" Coulter Odyssey red tube that I bought used for $200 in the late 90s. I don't know if I have a photo anywhere, perhaps I'll stumble upon it sometime. Coulters had crude hardware, but that was the scope I used to gain my first view of Pluto at a star party near here known as RTMC (now defunct).  

 

Having aperture fever at that time, I spent way too much money (just ask my wife!) on my then-new hobby by ordering this Starmaster 18, w/Zambuto f/4.3 primary, ProtoStar secondary, FeatherTouch focuser, and Sky Commander/Sky Tracker goto, as well. I saved some money by not ordering the transport handle option from Rick Singmaster and fashioned a pair myself (this did not assuage her).

The largest scope I will ever own, this instrument showed me a great many deep-sky wonders (blue supergiants in M31, no less), but after 16 years I finally grew tired of transporting it to dark skies, the setup and teardown (the mirror/cell in its box weighed 75lbs) and sold it off to a good home.

Do I miss it? No question, but I have no regrets.

Superb! That looks like an outstanding telescope. Thanks for sharing.
