This list contains only the major parts of my astro-equipment:
Telescope Meade LX90 8",
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 programsBack to top

Whoever would like to know more about these projects may contact myself via Email.
The polar mount in roof-light
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'.
Laser-mirror for polar alignment
to fasten the Meade LX90 on the Celestron polar wedge is made of thick plywood.
Camera-Adapter for LX90
As mentioned above, a notebook is integral part of my astronomic equipment.
For preparation of observation nights and during those I user a program called
to control the telescope and log observations.
The photo shows how the monitor brightness is reduced by a red foil (source
With this foil the keyboard is so dark, that I can not type any more.
The solution are two red LEDs integrated into the clips I use to fasten the red foil:
Implantation of a Bluetooth-Adapters into LX90
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.
