Hi,

Just joined this group and would like to solicit your opinions on
encoder resolutions for the GM8. I have picked up a set of used
encoders from a GM9 and retrofitted them on to my GM8. The encoders that
came with the GM9 are labeled 2160 and will only work with my Losmandy
DSC when programed as 4096. Has anyone out there used higher resolution
encoders on their GM mount? Is there an advantage?

Also I am still struggling with the two star alignment procedure. Does
every one have to go through the 90 degree alignment setup before
getting accurate DSC read out?


Thanks...

Has anyone mounted a C9.25 using the Losmandy dovetail? If you put
the DC9.25 on the top of the scope you have to flip the scope upside

Hello Robert,

I don't understand the problem. I'm planning to purchase a G9.25 OTA to
use it with my G11, will I have problems to install the tube on the
mount?

At this time I have the original Losmandy plate for the Meade 10", is it
possible to adapt it to the G9.25 optical tube? What is the exact
distance between the front cell's screw holes and the back cell's ones?

Thank you for the help :-)

Robert,

My feeling is your 9.25 should mount fine. If you were told you would
have to mount you 9.25 upside down, I am betting you can go the other
route like I did. I can carry my OTA around by the dovetail, solid with
no problems.

The mounting bolts will be at the extreme ends of the mounting slots on
the dovetail and will just fit the mounting holes. You may not be able
to use all four bolts, but like I said, mine is a solid mating of the
OTA and dovetail.

Take care,

So, uh Herm...
If you don't find one, would you be interested in splitting a pair?
I just replaced the connector on my RA drive after my G11's maiden
voyage after I <ahem> forgot to tighten the clutch and had not put
the counterweight shaft on!

Hi Bob:
Try Wil Milan at

(if he hasn't already replied to you), his e-mail address is on his website.
He spends time mostly on the APML and Takahashi lists so he may not have
seen your post. I don't have a C9.25, but he does and he uses the G-11, so
he must have worked out a good way to handle it.
Hope this helps...

Hi Bob

I just got my plate and it works the same way with the C9.25

Gregory,

Thanks for the info. I wonder if the hole pattern is the same
on the C9.25? The C9.25 also weighs a bit more than the C8 OTA
(about 22 pounds I think), but hopefully not enough to make a
difference. I think I'll try your suggestion because this would
be much less expensive than using the tube rings.

BTW, I'm having a hard time finding the DC9.25 plate. Neither
Pocono West or Anacortes have them in stock right now and I was told
that Scott is away until the 15th so I suppose that means I'll
have to wait to get them.

Regards,
Bob

Robert,

I too was told I would need to mount my C8 OTA upside down on my
Losmandy Dovetail.

I discovered otherwise. I used the standard dovetail for the G-11

and

was able to mount the OTA rightside up. It takes a little finesse,

but

it worked with no problems.

The plate is bolted using the opposite sides of the elongated holes
provided on the plates (thanks to Scott for that forsight) four

corners.

The elongation of the mounting holes is what helps, the bolts just

fit.

You can not use all four holes, but everything remains orthagonal,

tight

and trouble free. After continued set ups and tear downs and a road

trip

to Arizona's night skies, a mountain top star party, I have yet

needed

to adjust the dovetail mount on my OTA. It works.

Take care,

I'm looking at using tube rings in conjunction with the Losmandy
plates to avoid inverting the scope, but I'd like to know what
others may have done.

Yes, it does depend on what "local" means on the Internet.

Dick Smith Elctronics sells them.

Greg Crawford

"Ace Hardware" stores carry a 6 conductor splitter (part # 3108396) in
the telephone accessory section.

I hope this helps.

Who sells the appropriate splitter so a st4 and the hand controller

I guess that all depends on what is "local" to you. Here in California,
Fry's Electronics carry the 6-conductor duplex connectors. I tried Radio
Shack but they didn't seem to have them.

Here's one company that sells them for a pittance:



I read somewhere that they're called "RJ14" as opposed to the
four-conductor RJ11. Don't know if that's accurate.

Hi all,

This is my first shot after modifying the RA axis on my G11. The mod appears
to have accomplished the objective. The stars are much rounder and better
defined than before the mod. (See:

Thanks to all who contributed to advise on relubing the G-11.

With

Mark's and others advice, I decided to try this myself and did

indeed

find that all bearings on the RA & DEC were seized. The only

problem I

had was in the beginning of disassembly. My mount came with the

Losmandy

encoders installed and you must remove the shaft gear in order

to

disassemble the shafts. It is easy enough to do as a set screw

holds the

gear to a flat spot on the shaft. All the other instructions

were

complete and easy to follow. The only other advise I would add

is

paying

special attention to reassembly of the clutches to make sure

they

are

not to loose or tight. I found that if I tightened the clutches

fairly

tight before locking down the set screw worked best for me.

Any who have not attempted this really should. The difference is
tremendous and really should be listed under maintenance in the

manuals.

I expect to get much better guiding using my ST-8 just due to

the

lack

of friction that relubing cured.

Again, thanks for all the advise.

Clear Skies,

Steve

Steve,

What did you use to lube the gears?

Hello People,

I am a G-11 newbuyer from Brazil.

There are another Latin American in the group ?
