Hi all, I found a secondhand Meade 8 inch LX200 GPS EMC scope for sale. I am hoping to purchase this for my father who has been looking through an old 70's Jason for a while. I am confused by all the LX200 models (ACF, SCT, GOTO, UHTC) out there, can someone give me a heads up about different specs and if this one would suffice? He is pretty adamant about having it computerized, as he is older and doesn't want to spend too much time bending over to search. Basically, he would like to see comets, nebula, deep sky objects, and of course the planets, would this scope do that? Does not need to be too up close. Also, what would a secondhand price be for this? I am on west coast US.
