I think all el-cheapo's are teh same. I have one as well although they are producing reasonable images of Jupiter i do have to process some of the issues including a significant amount of purple around the edge of Jupiter. I know it is not the scope or the Barlow as my DSLR images are free of that colouring with it's inbuilt filter.
I am looking at purchacing a better UV/IR possibly Baader to go with my lense as well.
