It came with 25mm, 15mm and 10mm EP's and a 3x and 1.5x Barlow lenses. I find the 15mm with the 3x Barlow is the best for clarity/magnification. I cant seem to focus the 10mm with the 3x Barlow (on Saturn anyway).

For those of you using Peltiers to cooler your mirrors using computer CPU coolers as hotside heatsinks works well. They are about the right size and do quite a good job. They also often come with 12V fans however some of these can be rather noisy.

Bird: You might find those Peltiers work better if you drop the voltage a little. This sometimes helps as it reduces the load on the hotside heatsink. Maybe run them at 7V (between 5V and 12V rails on a PC power supply) and at a 100% duty cycle?

Cheers
