hello ~
I have an celestron 9.25 SCT..
& many eyepiece( 3mm radian, 7mm nagler.
19mm panoptic, ~ 55mm plossl : all-Televeue)
I bought focal reducer( Celestron f6.3) one week ago.
I can't focusing star connect with reducer except 55mm plossl(I see central ill defined dot (maybe due to central obstruction ?? )
when other highter power eyepieces ( 32mm. 19mm .. ) was connected,I can't focusing ( I was full rotating counterclockwise )
so .. I send mail to celestron ,,
reply was " because you use meade diagonal
( too far from focal reducer than celestron diagonal!!)
I change the 2" diagonal to celestron yesterday!!
but the problem in remained ,, I can't focusing ..
what is problem ???
my friend told me " you should move the secondary mirror
forward~~ ,, I can't do that !! )
help, me please...
I want more rich field !!
