Kal, by the way your 2x shorty barlow would be worth a try. You can increase he amplification factor by using a simple extension tube (say 50-100mm)beween the barlow and the camera. I recently sold my 2.5x powermate because I could get a better suited amplification (to suit most seeing conditions) using a simple 2x barlow (Vixen DX) with extension tube, resulting in something around 3x amplification - the 2.5x powermate actually decrease in amplification slightly with an extension.
cheers,
