I am unable to get my Gemini to point accurately. It has however

pointed perfectly for about a year until about two weeks ago.



I have reset the Gemini L3/Losmandy G11 by removing the battery. I

then removed the covers to the encoders and verified that all of the

set-screws were properly tightened and that the encoders themselves

were clean and in good condition. I also verified this with all of the

linkages from the motor assembly to the worm drives. I cleaned and

properly lubricated the worm/drive assembles for DEC and RA. The C11

tube with the dew shield is balance in RA and DEC with a very little

weighting to the east. Clutches are tight without slippage.



I then set it up as usually with the GPS. This followed by a ?Cold

Start?. I have gone in and verified my mount, time zone, Lat/Long, UTC

DATE and TIME. My time zone is now +7 MST/PDT(I live near Seattle). I

have been using:

Altar

Deneb a Cyg

Vega

Megrez

Alkaid

Kocab

Arcturus

Albireo



To for alignment and addition alignments for my pointing model. I use

the polar alignment scope for the polar alignment and use all three

stars(if you do not have one buy it / until two weeks ago it has

worked great for many many locations in the northern hemisphere) I

have verified that the mount is level.



So what is not accurate?



At the end of my alignment routine I will be pointed at Vega. I next

choose to go to M57. It is nowhere to be found in a 32mm eyepiece and

this is after I have done my alignment with a 15mm. So, I go back to

Vega and of course it is smack dab in the middle of the eyepieces. So

my next slews are to M92, M13, NGC6826, M101 and of course none of them

are in the field of view of view of the 32mm eyepiece. I can see them

in the finder scope of the C11. I do have my "good glasses" on and the

C11 is focused.



Is there something I have goofed up here, or not set, or just missed

because the coffee wore off? Suggestions?



Thank you,

You may want to check that your cables properly connected to the RA and

Dec motors. I've misconnected them more than once and was really perturbed

when nothing worked. Other than that I'm curious what your model says after

all the alignments. I have to rember that my alignment stars have to be

more than one hour RA apart, not too close to the horizon and generally get

three on one side before going to the other side.

David:



Thank you for your response. I did remove and inspect the cables. The system works to

conduct an alignment, however it just will not point accurately after the alignment. I also

cleaned and inspect the Gemini Motor encoder. It seems that they are connected

appropriately.



Each star for the model is displayed for verification and then accepted. I never have the

message, "Sorry, Rejected". I have received a recommendation not to us Alberio as one of

my stars. Again, the silly thing has worked flawlessly for about a year, and in different

location.



Again, thank you for your feedback.

New Battery. After taking out all those screws and removing it from the mount, a new

battery was in order.

Art,



I haven't seen all of this thread, so if this is redundant, I apologize in

advance.



One of my problems is that I get clear skies infrequently enough so that I

forget some of the less-obvious Gemini nuances. One of these nuances is how

you should go about choosing your alignment stars. It is not good, for

example, to hold either DEC or RA constant while varying the other. The

sequence in which you use stars to form the model appears to matter.



Just a thought. Might explain why it worked fine for a while and then

suddenly it doesn't point well.



Good luck,



Gary

Art:

I've had some bizzare pointing when the stars I've used are too close

to each other RA wise. I've also had it happen when they were too close to

the horizon.

Have you looked at the "Show Information" tab (help me out Losmandy

Group here) to see how far off you are with the model. I use this to see

if my pointing model is converging or diverging. If it looks like it is

stabilizing around a reasonable number I stop the alignment process. If it

is diverging, I park the scope and redo the alignment model. I find the

reasons for the divergent model are what I've told you previously.

Sometimes I think the mount isn't "happy" that day and just hop around to

find stuff.

Team:





Thank you for the help.



The last two things that lead to resolution:



1. Spanking Brand New Battery(not the backup battery that has been in the field box for a

year)



2. Timezone set to "GMT, UTC, WET", for which I can not find a reference for in the manuel.

This is the default setting from the hard reset.





Targets are back to center of the FOV.





Thanks again for the assistance.

Dave:

I don't believe I have encoders. My G-11 came with the Gemini. It is

more likely operator error than anything else.

If you are using encoders, disconnect them as they confuse Gemini. This

was my pointing problem. TY Dave ----- Original Message -----

I've had some bizzare pointing when the stars I've used are too

close

to each other RA wise. I've also had it happen when they were too close

to

the horizon.

Have you looked at the "Show Information" tab (help me out Losmandy

Group here) to see how far off you are with the model. I use this to

see

if my pointing model is converging or diverging. If it looks like it is

stabilizing around a reasonable number I stop the alignment process. If

it

is diverging, I park the scope and redo the alignment model. I find the

reasons for the divergent model are what I've told you previously.

Sometimes I think the mount isn't "happy" that day and just hop

around to

find stuff.

David:



Thank you for your response. I did remove and inspect the cables.

The

system works to

conduct an alignment, however it just will not point accurately after

the

alignment. I also

cleaned and inspect the Gemini Motor encoder. It seems that they are

connected

appropriately.



Each star for the model is displayed for verification and then

accepted.

I never have the

message, "Sorry, Rejected". I have received a recommendation not to

us

Alberio as one of

my stars. Again, the silly thing has worked flawlessly for about a

year,

and in different

location.



Again, thank you for your feedback.

Hi Dave

If you have version 1, you should think about upgrading with version 3 for the gemini controler. Good luck with your pointing problem. TY Dave ----- Original Message -----
