I am basically just trying options at the moment because I am very new to all this and it was an affordable option, I am happy with it as just a visual eyepiece. I was trying for a bit more magnification that just the prime focus setup. Next option is a Barlow but there are no ED 2" barlows in the country at the moment.
The distance from the eyepiece glass to the ccd plain would have been approx 70mm.
Thanks for the reply
