My Equipment
My current setups revolve around a Losmandy G-11 with Gemini goto. What a work
of art! However, it is quite fiddly (the LX200 was cake compared to this), and
after several outings I've finally managed to get the hang of it. It really
tracks well, and the Gemini goto almost always puts objects right in the center of a
tiny webcam CCD. And with a Canon Digital Rebel XT's much larger CMOS imaging
device, no misses at all. Here a Meade 152ED piggybacks a Meade 90mm guidescope:

On a wild hair, I recently acquired a used Meade 10" LXD75 Schmidt-Newtonian OTA and
mount, from my favorite website Astromart.
My plans for the 10" SN are to perch it on the sturdy G-11 and take photos.
The mount is barely adequate for the heavy 10" OTA, but along with the Autostar,
makes a great little visual platform for the William Optics Anniversary Edition 80mm
refractor (a.k.a. Ruby, the Red Temptress ;) The best part of this arrangement is the
easy setup and teardown: just pick it all up and move it as one unit!
Here's the Red Temptress riding shotgun with the 90mm guide scope on the G-11:

Past Equipment
Some past OTA's that I've had the pleasure to own and use include a Celestron C9.25" SCT, a Burgess Optics 1278
refractor, an Orion 80ED, and a StellarVue AT1010. In this configuration (pictured below), a C9.25 SCT
and a C80R guide scope ride together on the G-11 via a Losmandy DSBS:
In another configuration, a Burgess Optics 1278 and a StellarVue AT1010 ride together on the G-11.
Of course, without the DSBS, any of the OTA's can/could ride alone:
The past equipment I've used with the G-11 were:
- Celestron C9.25 flocked carbon fiber tube with Starbright XLT coatings (9.25" f/10 SCT)
- Losmandy DC9.25 dovetail plate
- JMI NGF-S motorized Crayford focuser
- Russell Optics' 10x60 finder
- Orion 80ED (apochromatic 80mm f/7.5)
- 125mm ADM dovetail mounting rings
- Losmandy DMM dovetail plate
- Burgess Optics 1278 (achromatic 127mm f/8, rumored to formerly be Bill's personal 'scope)
- Losmandy DUP dovetail plate
- Russell Optics' 10x60 finder
- Celestron 80mm refractor (achromatic 80mm f/11, for auto-guiding)
- 125mm ADM rings
- SocalAstro DUP-15 dovetail plate
- Canon 300D (a.k.a. Digital Rebel)
- IRB filter replaced with clear glass
- TeleVue 4X Powermate
- William Optics 2.5X Apo Barlow
- Meade Series 4000 f/3.3 focal reducer
- 1.25" Lumicon UHC and Deep-Sky filters
- James Lacey LazyFocus PC-focuser interface
Before the G-11 arrived, I used a Meade 10" LX200 for a couple of years (pictured
below). This was a great 'scope to start with, very forgiving and quite
accurate. I decided to move on to a GEM to be able to use different OTA's.
The goodies I used with this 'scope (not already mentioned above) were:
- Olympus C-3030 digicam with ScopeTronix T-ring adapter
- Meade SuperWedge with some custom work and fasteners added
- Meade dew shield (street light shield more like it!)
- Losmandy DM10 dovetail plate and radius blocks
- Losmandy WS C11/M10 counterweight (with some additional "homebrew" weights added)
- Van Slyke Versa Port Slider
- Rob Roy LX200 keypad joystick (great addition!)
- 2" Sirius Optics MV-1 filter (ugh - killed it trying to clean it :/ )
I also used a motorized Meade LXD500B GEM with the AT1010 when I just wanted to look
around for a bit and not set up the big monster. It worked quite well for visual use,
but was frustrating with the webcams.
Observing Site
As for my current backyard site, I've got a pretty crappy view to the north (Phoenix
sky-glow) and a horrible view to the east (Tempe, Chandler & Mesa sky-blast), but
from the zenith to the south and to the west, the sky is fairly dark. As you can
see, I'm smack in the middle of the "red zone", where the Milkyway at best is very
faint at zenith, M31 difficult and indistinct, and the sky is grey up to 35 degrees.
Limiting magntidue 5.0 to 5.5. I need to get out to some real dark skies more often!
