Hello...
and a belated Happy Xmas to all!
This is my first post for a while, after I got the balls to take my EQ5 to bits and perform the AstronomyBoy modifications and improvements! Thanks too to mill for the motivation through his "how to" article!
The AstronomyBoy webpage is invaluable to those with EQ4/5 mounts - the results after the mods are obvious and worth the effort IMHO!!
The smoothness in both axes is great and the lack of slop and responsiveness of the hand controller and autoguider are joyous!!!

Attached pic of M42 and running Man Nebula is a single 10 minute exposure @ iso100 through the ED80/Canon 40D and autoguided with PHD on the "new and improved" Skywatcher SynScan EQ5.
Please feel free and easy to comment - I had to crop the image as the longer the exposure / the greater the coma with the ED80 - so I find I have to really take greater care in central FOV composition.
All the best - and I wish you all a prosperous New Year

Cheers
Doug
