Stan, I have the 8 inch SN on the LXD55 mount. The mount has been working fine without any modification. I still don't think I have the scope properly collimated however. Russell "Stanley A.

I have read, for example, that coma is about half that of a Newtonian, but I do not know what half would look like in an actual field of view. Probably the best way to find out if mine is performing as expected is to get together with other owners of LXD's and see how their system performs. If there are any other owners of LXD's that may be at some future star party please let me know and I will try to attend. I plan on being at the 5 Mile Meadow this Saturday.
