Thanks for the update Thomas, I am so excited and can't wait to get the new
scope! :-)
Best wishes,
   Julie  :-)

Hi,


    I finally placed the TMB 105mm on the Giro today. When I popped in
the N5 31mm, the scope flipped up. No matter how I tightened the knob
on the Giro, it would not work. The other Naglers seemed alright.
Anyone have a similiar problem?


                                                   Marc Zukoff

Marc,
I don't have the TMB but I do have a TAK FS-78 mounted on the Giro 2
DX.  You need to find a better way to balance the scope.  If properly
balanced it should not move in altitude even with no tension on the
lock down knobs.
Thanks,
Karl

Marc:  Move the OTA so the rings are close to the focuser, then place
the counter weight(s) way out on the extension shaft.  I had the same
difficulties with my 100 f/8 / GR-2 DX (used a towel to grip the
knob), and this procedure worked great with heavy eyepieces.  I'am
using a 5Kg c.w.  The mount is performing better than any alt/az I've
used in the past.

Hi,


    Thanks for the suggestion. However, unlike the F8 the F6 has a
very limited amount of play as to where the rings can be placed.
Especially with the mizar mounting plate I am using. I will try
putting the additional counterweights further out.
    Aside from the balance problem, I must say the scope is
incredible. Amazing detail on Jupiter. I was able to spliteta orion
in fair seeing conditions. I just wish getting the lens cap on and
off was easier.

(I'll try posting again. Unsuccessful the first time. Yahoo is so
unreliable on posting recently.)

I put a folder in the "Files" section on this group that has my
modification pics to the GR-2 arm so that it can accept the Losmandy
GM-8 saddle plate. Pretty easy to do with hand tools.

This allows the TMB105 to slide further forward than it can using
only the rings, so that the scope will balance fine with a Nagler
31mm. No drag on the friction knob is needed except at very high
angles of elevation.

Added bonus is that I can now use all my scopes on the GR-2.
(And don't ask me about the Mizar thing, I didn't order it.)

Hi John,


       That looks interesting. I will see what I can come up with. I
agree with you about having a handle on the lens cap. I like to cover
the lens if the scope is to be left out for any prolonged period. It
is difficult to get the cap over the lens with the dew sheild in
place. I might ask Markus to machine a cover for the dew sheild and
maybe redo the cap to add a handle.
     Althoug my review of the TMB 105 was not nearly as technical as
yours, I was extremely impressed with the capabilities of the scope.
I can't imagine a better 4 inch refractor. I have to see how the Tak
90 compares.

Extra technote,

By the way, the holes are 1/4-20 thread. As the pic shows, the holes
are drilled at right angles to the original holes. I first used a
1/16 inch drill to make an accurate "guide" hole then used the 1/4-20
drill & tap set. Used a hand drill for everything.
Took me about a half hour.

Regards,

John Ford

Hmmmm!  If you look at my reivew of the Coronado 90m H-alpha filter,
you will see the TMB 100 with a large, 2" blocking filter in the
focuser, then the whole setup for the AP/Binoviewr, and then 2 Tak
Les.  This is my standard solar rig using the Giro-2 and I KNOW that
outweighs a 31 Nagler hanging off the back.  (And, as I recall, I
have used the 31 in a variety of scopes on this mount, no problem.)
Something is strange, Marc, but is seems like it is just out of
balance.  Dave

Dave,


     I do not believe I am overlooking something. There is no way to
adjust the tube rings with the 105mm when using the universal
mounting plate. The rings can't be slide any closer to the focuser. I
will see if Markus has any ideas. With your F8 there is some
flexibility in where the scope can be placed in the rings. Not so in
the 105mm.

Okay, I see the difference.  Perhaps an undertube balance weight
system may work.  Assuming there is room underneath the tube by the
focuser, you could jerry rig (to see if it works) a balance system by
taking a velcro strip and putting it around the focuser end of the
OTA.  Then using some flat weights/fishing weights, etc, and
the 'attachment' velcro, add weights underneath which can go on or
come off as needed.  The velcro will not mar the finish of the OTA if
you use the kind with the smooth interior side to wrap it around. The
only tools you would need would be a knife to cut it with.  Sounds
crude, but cheap and simple.   Try it and let me know how it works
out.   Dave

Marc,

If I understand your problem correctly, the difficulty lies in
balancing the short tube of your scope with a heavy eyepiece or some
such on back. I had a similar problem balancing the very short FCT-76
using a Tak Twinview on a Teegul. Art Ciampi recommended putting a
Tak accessory ring, which is moderately heavy, on the OTA. I did him
one better, by purchasing the accessory ring for the dew shield,
which makes balancing even easier, as it counterbalances the Twinview
better in that position.

Now I do not know the outside diameter of the TMB dew shield, but it
is possible that the Tak ring might work, or you could have something
made, even a Parallax ring would be fine. You could then slide it to
the correct position on your dew shield for perfect balance. With the
Tak ring, I was also able to add some heavy metal washers,using the
big screw, to add even more weight when necessary.

Hope you all don't mind my recommending TAK in a TMB forum, but the
idea is a good one. ;-) And I sold the Tak in favor of a TMB!

Mike Mescher

My I humbly submit my latest tinkering.

The "Files" section has three photos uploaded that refer to GR2
modifications that allow the Losmandy GM-8 saddle plate to be mounted
on the GR2 arm.

I simply drilled and tapped two 1/4-20 holes in the arm face, at
right angles to the existing metric holes and fastened the GM8 plate.

This way, the scope can be slid forward further than is possible
using only the fixed mounting rings. The Nagler 5/31mm balances fine
and the tension knob is not even required, except at extremely high
elevation angles.

This arrangement also allows me to use any scope on the GR-2 that has
a Losmandy doveplate (all my scopes!). Don't ask me questions about
the Mizar plate thing...I didn't order it.

(I must also admit that I did this with hand tools. First a 1/16th
guide hole, then the drill & tap for the 1/4-20 thread.)

Regards,

John Ford

Hi Mike,


      I like your idea. I was thinking about replacing the rings that
came with the scope so I can always add in another ring. This or Jons
doctoring of the saddle from the GM8 should work nicely. In fact I
may just drill another hole in the universal mounting plate to move
the weight of the scope foward.

What!  Advocating intermingling of the species!   Recommending

Actually, sounds like a good idea, and the BackPolice will wink at

Hi Marc,

Instead of adding just an accessory ring ('dead weight') to the dew
shield, you might make an extra dew shield that slides over the
original one for balancing your 105/650.

Hi all,

Has anyone heard anything of Markus Ludes in the last couple of days?
No posts of him since last tuesday in this group, and since last
wednesday in the Refractors-group.
And he hasn't replied (so far) to an email I sent him almost 2 days
ago.

As I await my 105 I would like to know if I have it right, no dewshield cover.
To get the len's cover off the dew shield must be fullyretracted, is there
enough room to do this with the rings on andpushed all the way back to the
focuser. Last question, with the ringspushed all the way back against the
focuser what is the center tocenter distance of the center tapped holes on the
bottom of the ringsand are they 1/4 x 20. Thanks, Gary

So sorry guy's, when ever I put a post here using this web tv some of the words
run together and I know it can be very very annoying, I can't find out how to
stop this, I click on wrap word's could this be the culprit. when I click on
preview everything looks fine. Gary

Hi,

     There is no dew shield cover. Getting the lens cover off is
possible, but a little tricky with the dew sheild extended. Once the
rings and scope are placed onto the mounting plate, there is no way
to slide back the dew sheild. The scope is very short. The center
hole is 1/4-20. You are going to love the scope. If I can't find a
source to macnine a nice dew sheild cover, I will try to find an
acceptable alternative. I hope I answered your questions.

A friend of mine ordered a cover from Thousand Oaks- the solar filter folks. He gave them the dimensions and asked for a cover made out of aluminum, just like the filters, but solid, with no hole for filter glass. The price was very reasonable, IIRC.

Mark

Hi Gary,
If the rings are pushed together, the threaded holes are 1-3/16
inches apart. Yes, they are all 1/4-20 threads. With the rings pushed
all the way back, the dew shield can come back far enough for the
original lens cover to be exposed by about 1/4 inch.
I suppose you could set the scope up with the rings all the way back,
and have the ability to slide the dewshield back every time.
Actually, Markus' solar filter holder could also be offered "without
the hole" as a previous poster noted for the Thousand Oaks option.

For the "compact" freaks like me, the problem is where do you store
the extra cover? It probably will fit (tightly) in the case over the
dewshield, but then it will be difficult to pull the scope out of the
case. I suppose a finger loop sling around the cover would allow this.

I have the 100 f/8 in the CNC tube.  Apparently these scopes
don't come with dew shield covers either , but I would not mind
buying one that matches the tube design.  A dew shield cover is
much more convenient than the lens cell cover.  My 180 (in the
William Optics tube) came with both.

Ruud,

Gary,

    That is correct, there is no dust cover for the dew shield, as
the dust cover is directly placed on the lens cell. I told Markus
to make dew shield dust covers for my TMB apos, but nothing has
been resolved on this issue so far.

    I am able to remove it with the dew shield fully out, but I do
agree it does take a little effort. Some people have put a simple
knob on the dust cover, and then it is a snap to remove. In any
case, we are working on this, and I appreciate any comments to
improve our products.

   It depends on the mounting block that is used. Yes, all the hole
tapping's are 1/4 x 20.

TESTING

if there is still a problem, there is another way, which works 100% shure.
We offer also davetails and rails attached to the rings , than the rail can
be moved forward and barckward, just like an Vixen scope on Vixen Mount
