Hi all
First time out imaging for over a year. Almost forgot how to set everything up again. But I am glad to say that the problem of ice forming on the ccd chip seems to have been finally solved. Thanks to Rui in Portugal for repairing a seal on the camera that was letting in moisture. So here is a test image LRGB taken of good ol' M13 on 2.5.10.

L = 35x30s
r= 7x30s
g=7x30s
b=7x30s
Taken unguided with Lx90 in altaz using atic 16ic CCD camera, stacked using Deepskystacker and LRGB combined using Nebulosity.
Thanks
DB
