crayford hell
well were do a start,i decided to by a low profile crayford to better the scope and help with my pics adventure,well just put in a normal 1.25 ep in is a hassle and takes a good 5 mins to get focus because not only ,do you have to pull the ext tube all the way out,but also the 1.25:holderthat the ep sits in what a hassle the 12"dob was so easy to set up with the rack and pinion focuser.i had a long 2" skywatcher t adapter which was just to long when use in the cannon camera and ended up by in the short 2"one from flo.that was fun and games in its self but got that sorted all was fine the camera gets great focus.
so my next headache started with the cape instrument uw80 f30mm ep , i thought this would make a great first 2"ep and after a bit of "duff advice decided to buy it for near on 55 quid, only to find out this time it can not get far enough away from the crayford even with the tube fully out, it would get focus if a held it just above the focuser so what to do ,do a by a ext ring just for one ep or by a star diagonal and use it in the 90mm meade frac ?. when a did end up getting focus it was usless the stars in the middle were fine,but round the edges rubbish the pain in side was welling up so a called it a night.a see flo do Baader T2 Extension Tube
am not sure if these would screw on to the bottom of the 2 inch ep, to give me a bit more lenght am sure some one will put me straight ,as these ext tubes come in all lenghts but i do not think these are what they are for . (add in lenght to my 2" ep) so my troubles will end with this some day any ideas why the 2:cape will not get focus a no it needs to be longer at the bottom so it van,get further away from the low profile crayford .
