On my Meade 2080 LX6 Premier, I've done the following:

  • Peterson EZ Focus kit (adds roller bearings to focus knob innards)
  • ScopeStuff Fine Focus Knob (gives larger diameter surface to focus knob)
  • Customer helical focuser on my Meade 1.25" prism diagonal (allows that FINAL layer of fine focus similar to Baader Focusing eyepiece holder)
  • Telrad
  • Dew shield

Other than that, she's pretty stock. Obviously I put most of my effort into improving the focusing - which for me was a BIG help. I now get that same "SNAP"! focus that I get with my f/10 refractor.


My custom helical focuser on my diagonal:

I started switching over from the WO 2" SCT diagonal to the WO 2" RotoLock this morning before work. This evening I'll take it apart and attach the filter drawer to the new diagonal.
Using the RotoLock set up will allow me to more easily re-orient the eyepiece (or camera) as the scope tracks across the sky.

Got fully switched over to the Roto-Lock set up with Gerd Neumann filter drawer.
Here it is with the Celestron 0.65 focal reducer in place:

And here it is without the focal reducer:

I'm an alt-az observer and use several side-saddle mounts. Here's a C6 in rings (GSO 176mm) so I can control the focuser position. The diagonal is a Baader prism with T2 components that gives me about 90mm of path behind the port. The FT microfocuser is a delight to use but a bit of overkill since the stock focuser wasn't all that bad. I have an AstroZap dew shield but seldom use it since I live in a very dry/dark location.  I'm currently working on a similar setup with a C8 mounted on a Losmandy AZ8 (waiting for Parallax rings).




Not visible in the photo are a flocked baffle tube (essential with the C6) and a set of Bob's Knobs for easier collimation (rarely necessary).

When I had my C11:

Losmandy dovetail and radius blocks
Bob's Knobs
Flocked the inside of the OTA
Installed internal dew heater
Installed fans
Added MoonLite Crayford focuser
While I had the scope disassembled for other modifications I cleaned and regreased the primary baffle and the stock focuser

Replaced the focusser on mine: https://www.cloudyni...rtouch-focuser/


... and a trivial modification to add adjustable drag to the Baader focusser...



I also have the motor drive kit but haven't fitted it.


Also using an APM diagonal with a roto-lock clamp but I don't consider that a mod...
