Hi all,

sorry by the 2 mails, I forgot the title and there
was a typographic error...

That's my first try with a digital reflex, Canon 300D.
The shot was made by Javier Diez and me with the 
60 cm. f/8 RC. There are 7 - 30 seconds exposures 
combined.

There was a little big problem: we felt the shooting cable! 
And we had to push the obturator button with the finger. 
Because of the improvised adapter to the eyepiece holder 
(an 1,25" Meade eyepiece proyection adapter), there 
was a little flexure on it that caused a slight movement 
of the camera at the beginning of each exposure. But 
the overall data whas pretty good. The other problem 
was the poor seeing caused by the telescope electronics 
(we have to put the electronics outside the dome, because 
this increases the turbulence from 1"-1.5" to
3"-3.5").

Well, more details on the web:

Comments wellcome, 
Vicent.
