Jason, you may want to check my thread at
http://www.iceinspace.com.au/forum/s...ad.php?t=37520 for a picture of a cheap solution without using a finderscope. It's on the second picture there with some details at the end of the thread.
If you are interested in it I can post a couple of advices on how you can find this little and fast Mak for yourself. It will take some time to get it but it'll worth it.
cheers,
Mike
