So you are using your "on camera" guider and not something like a DSI
or independant webcam to guide with.

Thanks,

That's a good question Hunter. As far as I know I have not loaded

ASCOM

onto this newly populated pc yet so I did not even access the panel

you

mention. I just selected on-camera for mount type in PHD. I

should have

double checked the guide rate on the AP hand controller however.

The last

time I tried AG it was set to 1x and assumed it did not change,

that's a

poor assumption on my part, I should have looked.

Gedas,

What guiding rate did you set the AP ASCOM driver to (on the ASCOM
panel - NOT the PHD settings) when you used PHD - I believe it has
1x, 0.5x, and 0.25x as choices. I was wondering which to use

when I

give it a try. Also, while I'm asking, what RA aggressiveness did
you select.

Murray, I use a 900GTO and the Orion guider along with PHD. Last

week I

tried the guider for the first time and found that for my rough

alignment and available stars, 2 second exposures provided me

with

perfect

round stars for my 15 minute test frame. I'm sure I could have

gone longer

between exposures but since it worked I didn't mess with the

settings after

that. One note, I did have to reduce the ms step size from (I

think the

default was 1000ms) to like 100ms. By default, the cal star

would

quickly

leave the cal box if left alone. Once I changed it to 100ms,

this

reduced

how far the mount would move and I had solid guiding.

Subject: [ap-gto] Autoguider correction frequency

I have just bought the Orion Starshoot autoguider camera and

have

got

some very sharp images with a TAK scope on an AP900 mount.

Has anyone else tried this system and if yes, what frequency

setting

do they have for the corrections. I have a friend with a

Paramount ME

who says his guider corrects 10 times a second; this seems

rather

high

to me. Does anyone have strong views as to how often the guider

should

correct a reasonable AP900 ?
