Subject:	information about the right T ring for ETX 90EC using a minolta slr camera

I purchased a meade ETX 90EC  sometime back. Now i want to turn my
telescope into a powerful lens by attaching my camera to it. I already
have a #64-T adapter, however i dont know which T-ring would be right
for my camera which is a minolta dynax 300si, a slr camera. I know that
the normal minolta T ring does not fit this camera as my friend has a
normal minolta t-ring and i ahve tried it on. Maybe the Minolata maxxum
T ring will fit my camera as both os these cameras are slr or is it that
there is no T-ring for a minolta dynax 300si camera. I request you to
kindly help me in this regard. A quick response will be highly
appreciable.

Thankyou

This was one of my first tries at astrophotography using my ETX-90. It
was taken at prime focus with a 15 year old Minolta Maxxum slr and Kodak
400 film. The local Eckerd scanned the negatives onto a disk for me and
I adjusted them in Photoshop.

Love the site. 
I have had an etx 90 for about 1 1/2 years now. I have a quick
question..

I have a Minolta 700si, the T-mount and a qualide T-mount adapter for
the maxxum. When I put everything together, I see the adapter as a
manual focus lens, get a reading of time, but not of aperture. (I see 90
--) The mirror will not drop. (assuming the camera thinks it is missing
a lens)

Any ideas?

Jeff

I found the answer. I was surfing around the Minolta site and found the
answer on their lens question/answer area. (I can email the link if you
want it for reference) Nutshell: They have the 'safe' feature in the
cameras to not drop the mirror/lens if the camera computer does not
think there is a lens there. (or if you have an attachment that they do
not recognize ) Anyway.. each camera can be set to over-ride this
feature. They give a chart on the link. For my camera, the 700si, you
have to push spot and card at the same time you turn the camera on.

Oh.. I know this might sound silly... Last night I took a few pictures
of Jupiter and its moons. Through the camera it looked very small. Is
this the case or just my view? (etx 90)

And:

What do mean by prime focus? I'm assuming you mean if I flip the mirror
to use the t-adapter connection? How would I do either?

Excellent web site!

I've got an ETX60, a Meade Basic Camera Adapter and a Minolta X-700. I
can't seem to get anywhere near focussed with this setup. It seems that
the camera sits too far away from the 'scope... I've tried it with and
without an eyepiece in the adapter, but no luck. Any ideas on what I'm
doing wrong?

TIA,
