Meade LXD75 8 SCT

#1

Post by Don Quixote » Tue Jun 25, 2019 1:20 pm

I would like to convert the 1.25 visual back on my 8" Meade LXD75 SCT to a 2" visual back.

Is there a Meade specific adapter?

Any advice would be much appreciated. Thank you.

I woulda sworn Scopestuff would but I couldn't find it.

Agena astro has one.

But you might check with scopestuf anyway. He does have 2" Crayford Focusers for SCTs.

You're Welcome.

Looks nice. Now we need a pic of it on the scope.

You're going to appreciate not having to deal with image shift. Especially when colimating

The guy at Scope stuff is great to work with. I got my collimating knobs from him. At the time he didn't have a 8" Meade SCT Example pic with the six screw Sec.cell,so I sent him mine. It's the one on the right on the striped sofa cushion

I will have it mounted tonight. I think focusing will be easier as well with the fine focus ability of the 1 to 10 knob set.

Then I need the dovetail.
Your are of course correct I need more mount.
But I want to get a look see before I go deeper into my pocket.

I set it on a bench outside yesterday and looked at the tree leaves about 1/4 mile away. In the daylight it seems to suffer from a lot of stray light so contrast seems soft. I am hoping that dark skies will look different in that regard.

a dew shield could help ,too. 8" ers and up catch a lot of light. darker skies should help.

also, if your buddy has a f6.3 focal reducer se if he'll let you use it. Lower focal ratio by definition means reduced effectivefocal length for agiven obj. dia and in turn magnification which will yield a larger exit pupil=> brighter & more contrast.

Ecit pupil mm = Obj dia./ Mag.
