The post-a-pic thread is one of my favorites, with great ideas and examples of craftsmanship by the DIYers, and closer looks at what's out there with manufactured scopes. The moderator split the thread into a part 2 not because of mine, but because of so many before.

Finally got a good pic of my 12.5-inch f/6.3 Newtonian, completed over a year ago. (And finally learned how to post pictures here!) They should take me away for putting such a large scope on top of a Meade LXD-75 mount! It rocks 'n rolls (in the motion sense); photography is unthinkable. But views of DSOs and planets alike have been thrilling. The OTA structure itself is rock-solid, and would be great in a "Dob" mount, but I like the goto and tracking. My first DIY scope - many lessons learned and modifications planned.


Features:

- Split truss great for getting through doorways - the bulky upper unit is light in weight.
- Box pier built to hold the scope as low as possible, and permits views to the zenith.
- Extended counterweight shaft with only 20 lbs balances the 40 lb scope. (Total supported weight is the same as Meade's SN-10 setup, but the bending moments are greater.)


Components, credits:

- Primary mirror made locally by the shop now known as Optic Wave Labs
- Protostar secondary mirror and arch vane
- Wyoroc focuser
- University Optics floatation cell (discontinued)
- Stellarvue right-angle finder (local)
- Silenx 12VDC fan from Fry's is silent and vibration-free (it doesn't eliminate thermals from the pavement, however.)
- R.F. Royce for construction concepts (Many liberties taken; I might have also used his rotating head design, but needed to save weight.)

Beautiful scope, but that LXD75 looks like it's screaming in pain. :)

This is my first scope. It’s small and humble, but I can fit an entire galaxy in there!

Its fun to go through this thread (and part 1) and see the different equipment and the ingenuity that some used to personalize their settings. What I really enjoy though is seeing the observation sites in the pictures of some folks (for example Carol’s, Scott’s, jg3’s above... among others). There’s just something about looking at a scope in its playing field.
