Hey All...

I'm wonder if anyone has tried this or thought to try this... I have an
ETX-60 (lots of fun so far) which is a 60mm achromatic refractor. Now with
the ETX-60 and 70 the front objective lens can be removed. Has anyone
thought to remove that lens and replace it with an apochromatic lens? The
Backyard Astronomy guide shows that the difference between the two are the
number and shape of the lens.

I would think this is more than a garage project as someone would have to
figure out the optics to fit the tube and mirror design of the ETX-60/70.
Since the ETX-60 and 70 both share the same OTA only one kit would be needed
for both scopes. Given the fact that there are thousands (if not 10's of
thousands) of ETX-60/70's on the market a $100-150 dollar acro to apo
conversion kit might be a sweet little cottage business.

Any thoughts?
