Thanks for the reply,
Do you by any chance have a link to that guide scope that you was referring to?
I found their site a tad hard to search on but did find this one:
http://www.astroanarchy.com.au/teles...er_80x400.html
Not sure if that was the one you were referring to of not, but was looking for something simple to start of with.
Couldn't find anything on there about a short extension though.
But any links or advise would be appreciated.
Thanks.
