I don't know if these count as ETX-pictures but I'm sending them anyway.
 
Both galaxies were shot with my Canon EOS 450D through the C9.25. I used
the ALCCD5-cam as an autoguider on my ETX90-OTA.
 
M51:      F=1480mm, f/6.3, 18 x 150sec & 9 x   90sec, ISO 1600
M101:    F=1480mm, f/6.3, 34 x 120sec & 4 x 300sec, ISO 1600

Attached also a picture of my beloved ETX90 on the C9.25.
