I have needed to conduct long exposures where the AP1200 must start on the "underside" of the mount then track for 5-6 hours. This is easy to perform with...
Another month goes by and I have to ask about the status of the Adjustment for Worm Backlash for the 1200 mount on you Tech Support page. It seems such a...
I agree--am also anxiously awaiting pictures which will help me whack my ap1200 with a mallet. It is unlikely that I will attempt to adjust the mesh on my...
Two weeks ago I received my G11 w/Gemini as a fill-in for the AP900 mount I ordered in 2000. Yesterday I received notification of the AP900 mount. Somehow I...
I've used the gemini system on my friends Gm-8, and strongly disliked it. Without the keypad, It takes some effort to get use to. I regret selling my 6 month...
I've been trying to nail down the tracking on my 1200 (rec'd Jan 2001). I used an ST-4 that I put in the C-14 with a .63x reducer. I drift aligned with the ccd...
Hi Mike: But that's exactly what you would expect with periodic error: it has a repeating period equal to the rotation time of the gear. Because of the minute...
Bert Thanks for the response. I always thought that the periodic error was the little blips you see in the tracking graph. Like I said, I'm confused. Even so,...
... Also, if ... to drift ... center over ... Mike, I only own 1/2 an AP1200 mount (summer delivery), and am certainly no expert, but I believe periodic error...
Hi Mike: I don't know how your total error compares with mine because I never measured mine with guiding off. With guiding (ST-4) on, I got the graph shown on ...
Mike, Take a look in the files section in the periodic error folder, there's a couple of PE plots there including mine. Your PE looks rather large for a 1200,...
Hi group, This one was a challenge for a CCD beginner like me. Without the spot-on Goto I probably would have spent half the night looking for my targets. PGC...
Forgot to say that the 30 shots of 120s each were unguided ! i.e. the guide chip in the ST-10E was off and the 1200GTO was just tracking by itself (with PE...
I just want to introduce myself to the group. My name is Bill Gardner and I live up in Canada. I have just purchased a 900GTO off of Astromart. I had been...
Welcome aboard Bill, I've also got a 900 GTO and I absolutely love it. If you got the manual with it you shouldn't have any problems. It's pretty easy to...
Had cetain positions in Dec where the mount moved very little (at .5 guide speed) when calibrating on a guide star. Moving the mount a little (or choosing a...
I am planning on using my G11 tripod with the AP900GTO mount that will arive later this year. It looks like I need to make a 6" to 8" collar to accommodate...
Bryan, I use a G11 tripod for my AP mount -- it works wonderfully and is rock solid. I sent the top cup-like AP piece that the mount goes into to Scott ...
Following up on Richards suggestion, I ordered one from Scott Losmandy ( I had AP send an extra top cup for my 600E {$60+} to him for a pattern. That was in...
OK, I took possession of my 900GTO yesterday and got it home today. Went to plug it into my battery to get used to the hand controller and all...the battery...
Hello Bill, http://www.bills2way.com/equip/ps15.html Checkout this link, I've sent you to the model I have but to check others just delete the last /ps15.html...
Bill: Another suggestion. If you live in a town of any size, look for an amateur radio store. They often have used filtered, regulated power supplies like...
If you are planning on using an external power supply, you might want to consider protecting your equipment by adding a zener diode. For example, putting a...
I use the switch 12 vold DC supply that radio shack makes. It works in the US. It works in Hungary. There is no way to plug in the AP cord backwards since it...
The other way to do it is to go to wallmart and buy a garden tractor battery and a charger. One charge will last a long time. It's dirt cheap, not rated for...
Hi all, I also use the Pyramid PS-15KX and it works great. I got it from Kendrick Astro Instruments at http://www.kendrick-ai.com/battery.html They were very...
