Thank you Clayton, I hope to take a better barlow lens in order to obtain better results......
Hi Tom, thank you for your appreciations. The track was good, but I think it would be better if I'll provide to better balance the telescope:in fact, the addition of eos 550d and barlow on the focuser, at the end of the tube, definitely does not play in favor of the correctness of tracking ... However, when I taken Jupiter, at F/10, the planet remained in the approximatively in the centre of 640x480 frame for 60-70 sec (it moved just a little), the time necessary for me. I think that by adding a conterweight (1kg or 1,5Kg) on the prymary side of the tube, in opposite part of the focuser, the telescope should be well balanced. I'll use some magnets.
I think that the tracking of my telescope can be improved a lot, as you can see by this video (my tracking is not so good) in wich the author used the same telescope and a powermate 5x... perfect track, I'd say

In the next days, I'm going to buy a televue 3x barlow lens and I think to use it as a 4-5x too... I would like to buy a 5x powermate as yours, but it costs twice and for the moment it is impossible for me...

Nunzio
