Cassis is a small village with 6500 inhabitants 20 Km  East of Marseille, on the south coast of France
The  famous "calanques" are located here, they are similar to the finlandish fjords, only smaller.
I live in Paris for my work (IC), but I am very lucky to go two weeks-end each month to my house, which is near the Mediteranean Sea.
Here is my site and my telescope

Since 1999, I do CCD pictures.
My scope was a LX200 10" with a 6.3 reducer, and a ETX90 on it, with Losmandy rings, for autoguiding.
 Starlight HX516 is for guiding on the ETX and a MX916 Starlight for imaging.
I use a NGFS for focusing
At the moment, there is a lot to do with flats, guiding, balance,focusing, winds,etc...
 As soon as my technique  grows, I'll try do better pictures and to go to SN and asteroids

I began early 2001 imaging in  color using  RGB filter set from TrueTechnology, and  Homeyer filter wheel.
I use both PC and Mac for computers. I use Astroart, Prism and Photoshop software.

On 10/05/2003 I purchased a used LX200 12" Classic !!! . 
Optics are great, but it is big and heavy !

Now I do imaging with a ST7e and a AO-7.


This site is only beginning, and I hope it will going better and better (as my english !!)
I will add here tricks and tips for better imaging with my stuff.
Here are  some basic formulas for ccd imaging (field, resolution)

So far i do 300 sec shots, and I add it  5 to 12 times, depending of brightness of object.
