Hello all. You may remember a post of mine from a while back about the 12"
LX200s. Well, Im getting close to being able to purchase my scope and have
some further questions before I actually make my purchase.
1) I was told in my last batch of questions that the 12" has a larger
central obstruction than my 10" Newtonian and would therefore be of little
gain optically from my 10". Is this true? If so, would I be better off
getting the 12" instead of the 10" (because if the 12" is of little or no
gain, then that 10" would be a lose....correct?).
2) I was also told that as you increase in size in the LX200s, the mounts
become less stable. Is this really true? If so, would it be wise of me to go
down to the 10" for CCD imaging since mount stability is important? Or is
the difference in scopes hard to tell?
3) I notice that the 12" LX200 comes in only f/10. Since the 10" comes in
f/10 and f/6.3, would I be better off getting the 10" f/6.3 for CCD imaging
than the 12" f/10? Also, if I get the 10" f/6.3, can I still add the f/6.3
focal reducer to get an even lower f/ ratio?
Also, if anyone has any other info on helping me decide between the two I
would greatly appreciate it. Im sure I will have more questions later, but
Im late for a doctors appointment so I will leave it at this for now.
Thanks a million in advance!!
