Try my Observatory class 36mm
SWA for the ultimate view the ETX can offer. Check
out Pictures below text. Is
it advisable to use 2" eyepieces on a Meade ETX scopes? Is
there a benefit? ETX's have a relatively long focal distance for
a small scope and with 1.25" eyepieces cover a relatively small
section of the sky. With the right 2" eyepiece you
can at least double the amount of sky you can see. Sometimes it
can come close to triple. Is this a gain? The extra
apparent field is there, but can't be seen in a 1.25"
eyepiece. A standard 32mm plossl has a maximum apparent field of
52 degs. With my 32mm Ultra Plus with a 70 deg. apparent field
is almost double at 1.8x the amount of sky. With my 36mm
observatory class eyepiece this goes to 75 degs. apparent field, this
goes to almost 2.5x the amount of sky. So this represents
a tremendous gain and if you think about it, doubles. the
amount of light you are seeing because you are seeing more of the
sky. This adapter comes with full instructions and is easy to
install. The adapter slides over the 1.25" eyepiece socket which
increases the internal size because no 1.25" barrel is
inserted. This means that an incredibly low power, wide angle
lens can be used with zero vignetting. Can you image a 40mm with
70 deg. apparent field in your ETX? Many may have thought that
this was impossible, but with this adapter it works perfect and can
slew to the zenith with no problem. Also it does not interfere
with the finderscope.. The eyepiece shown in the photograph is my 36mm
observatory class. It has a 75 deg. fov . This
completely changes you low power viewing with the ETX.

If you get
one or more eyepieces below with your adaptor you can minus $10 for each eyepiece. If you have question call
or email
EX:
If you get 1 Ep's and the
$19 adaptor it would be
$39 + $19 = $58 total.
EX:
If you get 1 Ep's and the
$29 adaptor it would be
$39 + $29 = $68 total.
If you get 2 Ep's say a 10mm and 18mm and the

$39 + $79 +$19 = $137 total.

This
replacement adapter allows you to use 2" eyepieces in your Meade
4.5" or 114mm scope or a 90mm Meade DS refractor. You may also use 1.25" with the
optional 1.25" step down adapter.
Is
it advisable to use 2" eyepieces on a Meade 114 scope? Is
there a benefit? With the right 2" eyepiece you can at
least double the amount of sky you can see. Sometimes it can
come close to triple. Is this a gain? The extra apparent
field is there, but can't be seen in a 1.25" eyepiece. A
standard 32mm plossl has a maximum apparent field of 52 degs.
With my 36mm observatory class
eyepiece this goes to 70 degs. apparent field, this goes to almost
2.5x the amount of sky. So this represents a tremendous
gain and if you think about it, doubles. the amount of
light you are seeing because you are seeing more of the sky. .

Rings
w/mounting for all 50mm Finderscopes and small telescopes
$99
(#50mmRings)
Extra stop and aluminum
mount. $19 a set
(#50mmstops)
This is a universal
set of rings and mounting hardware for any telescope you want to mount
with it. Hammered finish and comes in Gold or Dark Silver. If you want
a custom color let me know.
There is
a Sky-Watcher Evoguide 50mm APO Refractor in the rings holder in the
(First picture). It fits by only taking off the end cap and sliding it
through. Why use this instead of the Metal rings that came with it. A
few very important reasons. All pictures are clickable. >>
These are
very light weight and have a custom way to mount on your telescope
using your existing hardware. Also it has an integrated place to put a
red dot finder(See pictures 2, 3 and 4). This makes whatever telescope
you mount in your rings easy to find their target even before you look
through the finder itself.
So you
are doing your alignment and want to find your guide star quickly.
With this setup you first can use you red dot finder to quickly slew
your telescope. Then you look through your finder/50mm telescope and
"Boom" your star in near the middle of the eyepiece the first time.
This makes doing a multi star calibration a real breeze.
Now about
the way it mounts. These rings mount on a round fully adjustable
Delrin Stop. (See picture #4). Once you mount the rings on this stop,
you have full adjustability in any direction. Notice how the stop is
bigger at the top? There are three adjustment 1/4-20 screws (See
picture 5) that allow fine tuning of the aim of the scope. Tilt
up/down left and right. Once tight the rings are held very secure to
you main telescope.
You will
not need to use the scope alignment screws that are "holding" the
scope to adjust the aim. The screws holding the scope itself are large
nylon 1/4-20 that hold better than the old mounting ring screws and
are completely mar proof.
Every ring set comes with full
instructions.
The Round Delrin stop has a bottom 1/4
-20 hole in the bottom. This means you can mount it on any tripod or
other mount that has the 1/4-20 screw. Great if you want to use this
as a spotting scope.
The Delrin stop can also mount on the
included aluminum part in (picture #6) the part in #6 is able to slide
right into your old finders dovetail mount.
