Milton, I`ve been trying to send this message all day-hope it`s OK this time. The link you sent me had C-mount to M-12 adapters (I think it was Optics Online). Since the Nikon lenses use an "F-mount" I think what I`d need would be something like this; http://www.astrovid.com/prod_details.php?pid=83

I probably won`t be able to afford one for over a month, though...

Mark;


Probably.


All you need to do is search Google / Yahoo / Bing with the phrase:


M42 to C-Mount


and you'll find lots..

Didn`t you send me a link to a place where the adapters can be bought

at one stage? I think I still have it Bookmarked somewhere!

Hi Milton, One of those C-Mount to M42 adapters`d make an interesting

experiment when I have some spare money. I have an old Nikkor 50mm

lens from my FM2 Nikon SLR.


I built one by using a hard plastic M42 end cap, cutting a hole

through the end of it, then epoxying a C-Mount male end on it around

the hole. For macro work, I picked up a set of M42 ring extenders

(also useful for getting the OAG and main scope in para focal too)

and can add them in as needed.


I`m tossing up whether to get myself a

Telegizmous 365 scope cover or go for the indoors satisfaction of

being able to play with a new copy of The Sky X in the meantime, next

month. We`ve certainly being having more than our fair share of rain

this year (it`s back again with a vengeance outside as I`m writing).

The Telegizmous covers are apparently tested with high pressure water

hoses as being watertight & also provide sun protection during

summer.


I use a vinyl silver BBQ cover as an outer liner and big clear

garbage bags as an inner liner for additional protection. It's

worked for me for 5 years now and keeps the scope cool on those hot

summer days too. Of course we don't have monsoon rains here, but

this keeps a lot of west snow off too.


TTYL..
