GTOcp2 controll. I don't keep the clutches very tight. I have checked the battery voltage to be good. The mount will not slew anywhere. It is still reading out changing coordinates to starry night and

Hello Mike, as you said, you have a good machinist's bubble level. So my experience is, leave the two star method. Set up your mount in the daytime and use for that the machinist's bubble level,

You are a hero! Great work and you've undoubtably changed some of those kids lives for the better.

You're a lucky man, Mike! Wishing you CLEAR SKIES Tom

My AP1200 is installed on the concrete pier, and I took it for its first run tonight (clouds and all). Prior to powering-up the mount, I set it up in the Park 1 position with an accuracy of better

Thanks Roland. If this is true and the 27TVPH can provide nice tight stars to 90 - 95% of the field what is the advantage of the much more expensive reducer designed specifically for the AP160 and

I do not at all wish to comment on US politics, but worldwide, non- trade education of the public seems to get thrown out very quickly when money is tight; witness the closure of the London

I'm looking at my options regarding imaging and one option that I like is the new Canon 5d Mark ii. I currently have an AP160 and use the 27TVPH telecompressor with my Canon Rebel. I can't detect

Can we please kill this thread and get back to discussing AP products? We have all had a chance to chime in and frankly I'm concerned it will turn into another political debate that we don't

I tried to post a reply yesterday but it did not get through. No reason to post it again. Glad that the situation with the planetarium in Chicago has been adequately handled elsewhere. After

<snip> Thank you for speaking up on this, and I hope you would also forward these thoughts to McCain. Just yesterday, NPR's _All Things Considered_ did a small piece on this very subject, and they

In fact, the bolts turned out to be in exactly the RIGHT spot for the SPA. I received my AP1200 yesterday (YAY!), and installed the SPA on the concrete pier today. I drilled and counterbored four

NPR (National Public Radio) just did a story on the Adler planetarium projector (about 3:45 central time). It may repeat later in the broadcast or catch it at npr.org. Discussion points: $3 million

Thanks Howard

While I agree with some of the points you stated and the fact that other counties now recognize the importance of a science/tech edge, both the timing and vehicle cited for regaining our traction is

Philip, At least your country didn't give huge $$$$ to something like Nascar for whatever reason. That money could have funded many great science centers of all kinds. Wonder why either canidate

Well said Rolando, there can be few things more important than childrens education, especially in such a deprived area as science. It's the same in the UK, or even worse. It's exactly this kind of
