Hello everyone,

I made a website with more details (photos, test reports) of
this wonderfull high-quality Instrument. Please contact me for the link.

The optics are simply first-rate. In times of steady seeing, I could make
out tremendous detail on Jupiters cloud belts. I was able to record detail
on Ganymed, Titan showed a tiny orange disc. There seems to be no limits in terms of magnification. Close ups at the moon with 600 times are
breathtaking. Double stars to 0.35 arc sec where resolved with that
instrument. The blue companion of Gamma Andromedae is splitted easily (2002).

With 12 inch you will find the limit for an instrument of this type. It is
small enough for easy transport. The polished main mirror and the light weight aluminium tube guarantee a fast cool down. No fans are needed to speed up.

Cause of the excellent work of Matthias Wirth (builder of the 10" folded TMB apo, shown on the WSP 2003) it is about halve! the weight
of the corresponding Intes Micro modell without loosing stability and strength.
