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? |
