Hardware
This list contains only the major parts of my astro-equipment:
Telescope Meade LX90 8",
a 200 mm aperture and 2000 mm focal length Schmidt-Cassegrain telescope (f/10)
with a heavy tripod and a Celestron polar wedge
2009 I made a changeover to 2" eye-pieces and Bluetooth
The picture on the right show the LX90 with polar wedge and tripod
In a South facing roof-ligth of my home I installed a polar mount , see below
Tordalk 15x80 Binocular made by CBS (Firma C. Beck und Söhne in Kassel) equiped with a diy-tripod-adapter
Meade LPI camera (LPI = Lunar Planetary Imager™),
a small webcam with 1 1/4" eye-piece-adapter.
(you will find details in the Meade homepage)
Digital reflex camera Canon EOS 1000D
(for details please look at the
Canon Homepage)
Notebook, Windows XP and several astro programs
The polar mount in roof-light
is superb for "instant" telescope observations.
The framework made of 30x30 Item profiles
is a rather strong and stiff structur.
Using special screws and T-Slot nuts it was very easy to build.
Both long horizontal profiles are fastened with very long screws directly to the roof beams.
On the left end of the top profile is a magnetic ruler that holds a checklist and observation plans.
The hook and two screws encircled red are very helpful to install the 30 lb telescope without another helping hand.
They hold the LX90 in place until the big center-bolt is tightend. Thereafter the hook is folded aside (see photo on the left).
This diagram shows the visible part of the sky seen from the roof-light (the green sections are invisible / below horizon).
Yes, I know that the house under my feet and the other houses around have a negativ effect on the
Seeing ...
but it allows more and "instant observations" compared to 'pack all equipment in the car, drive to a really dark site, unpack and install,
observe, pack into the car again, drive home and unpack once again'.
Implantation of a Bluetooth-Adapters into LX90
Usually you control the LX90 with a notebook through a serial cable connected to the Autostar handbox.
In case you get caught in this cable the risk of damage to both, notebook and LX90 is rather high.
Even higher when you have laymen around at a dark site.
The Bluetooth-Adapter GC BT Scope1 Adapter made by Gene Nolan is the solution for this problem.
(see Gene's Homepage).
Once I succeded to get this adapter transmitting data (see Bluetooth-Setup),
I was very pleased with this device. Only the cable spaghetti in the proximity of the telescope was annoying.
To overcome this "problem" I implanted the Bluetooth-Adapter into the left fork arm of the LX90.
Now I need only 3 cables at the LX90: Power input and two data cables between LX90 and handbox as show on the left photo.
For those of you who would like to do the same the details of this operation are disclosed in
