Thanks iceman for replying so quickly.
Collimation, thew word gives me the goosebumps. When I purchased the scope, it was because on the box it said if I wasn`t satisfied with it I could take it back for a refund. well it went back and I tried a second one. Could see the moon, but saturn... no. Then the technician in me came out. Why not. Read articles from 20 different sources as to how to collimate a newtonian. Made caps from film canisters, and adjusted and tested and adjusted and tested. got to a point where I saw 2 images of saturn in a blurry patch. Did a star test at the same time, 3 leave cloverleaf pattern.
I read the article at IIS about trouble shooter at GSO dob. astigmatism. I relieved the pressure on the mirror and packed it in so movement was almost non existent. put it back together and now its lots better. I know my daughter is impressed.
The eyepieces I purchased from astrobuysell from a person who said he won them at a star party. the 3 larger are series 500 and 10 and 12.5 have no branding but the writing is in gold lettering.
Can you suggest a decent barlow (or what to avoid) that doesn`t cost too much? I have read the list at Bintel and Andrews, and it leaves me confused.
thanks Marty,
