Yes, but I think you were right. A lot of discussion about AP mounts eventually gets into referring to the "base section". Quite often I see discussions on Astro Mart, and other places, and they refer

Czesc Dominik, Nice to see what the inside of the hand controller looks like. It would seem that there was a poorly wave soldered pad under pin 10 in the 28 pin "keycode decoder IC" - I assume that th

Hi Dominik, Your electronic friend was absolutely right about the "potential" keyboard corrosion problem! I just happened to be thumbing through the: "Astro-Physics GTO KEYPAD Version v4.12" user manu

I wonder if someone at AP might consider eliminating the N-S switch, in future versions of the GTO Control Panel. Indeed, use it as a lighted POWER Switch, which many of us have asked for. Seems to me

Thanks Roland, Glad that keypad corrosion is no longer a concern - and that the reference to it in the Trouble shooting section of the keypad user manual, will be removed in the next revision. After a

Hi, I was wondering if there has ever been a consideration of adding "pulsed power" control for the PASILL3/4 polar scope. This could be either an argument to the keypad command to change not only the

Hi Roland, This is good news - I was becoming concerned about "meticulously" rebalancing the counterweights, every time I crossed the meridian. Indeed, the AP900 is a superb design, and even more so,

Hi Roland, Not knowing the centre of gravity of your (160/F7.5) OTA, but assuming it is at mid point (23.6 inches), that would be approximately a moment of 189 inch-lbs. O.K. that is a useful working

Thanks Jeff, I had forgotten about the large initial worm stress, with no OTA. I suppose if it can (and must) survive that, then the normal imbalance is no issue at all, in comparison. I had some conc

Hi Dave, I'm glad you corrected my thinking. I had completely forgot the possibility of using it manually, without GOTO. In such case, definitely, a N-S switch would make good sense; it would be essen

Hi Rick, I guess I'm spoiled in wanting to use the LED to see the alignment reticle a bit more easily. Besides, it is difficult to spot Polaris most times, and nearly impossible in late dusk, around h

Hi Mike, There is a Horizon setting feature, which you can change. It's for defining the level of the "tree line" in your area, so you don't waste time chasing objects below that local horizon. Any ch

I think there was a note in the AP900 manual about the LED colour changing to indicate a power stall. What load is the mount carrying - maybe you are over it's capacity? Joe

Hi, Well the UPS screw up saga continues! That OPT shipment from California to Canada, I described below - and thought was finally out of courier hell - well UPS sent me a bill for all the duty, and g

Hi Bill, Good quote - I think Julius Caesar was purported to have said in the Latin writings from the Peloponnesus Wars: - "Veni, Vidi, Vici, Toga Habam" or in direct English translation: - "Been ther

I know ... but I use the "free verse" interpretation of "conquering". The new age California style phrase seems so much like the old one. I thought I had it right - which war and century did that old

Hi, Just got my "modified" DOVELM2 saddle back from a local machine shop, and the original design oversight, is now very nicely resolved. I had the original "4-hole bolt pattern" for the AP900 duplica

Hi Stuart, Just need to add one warning. To get the Draft-N router range and power improvement, the old laptop need a matching Draft-N NIC card. In order for an old laptop to use the new Draft-N host

Hi Stuart, Thanks for the explanation about the Linksys and windows. I too found this problem odd - and was very curious why my cheap (G class) Giagafast wireless router (set up as a repeater), was we

Hi Stuart, I think you need to go into the Firewall program (Norton?), click on Norton Protection Center's Personal Firewall, select configure. Choose Networking tab, click on ADD, and then the button
