Howdy
So i bought a Baader MPCC from a forum member, i thought it might come in handy, my dob is F5, and i intend at some point on getting a 16" that is F4.5 so you can why i thought this would be handy.
It arrived this morning, in perfect condition, and on time and it was a hassle free sale, i 'spose the point i am trying to make here, is that there is nothing wrong with the MPCC for defo.
;)
So whats my problem, can i get any eyepiece to focus with this fitted?
no.
It seems to move focus ever so slightly, which means when using a meade 26mm plossl, there just isnt enough travel outwards, and when using anything from a 15mm onwards, there isnt enough travel inwards to get it to focus, probably due to the 1.25 adapter and MPCC stuff. if i wanna use a 20mm all my life then i am in heaven.
I have tried this on two crayfords, that is two slightly different models, both from 12" dobs and cant get it to focus at all.
Has anyone else experienced this? or am i gonna ahve to buy another focuser, probably low profile, with extensions tubes
:shrug:
