Murray, On your first question, I think the telescope mount manufacturers are doing what they do best. I've owned several AP mounts and can't think of a lot of ways they could improve. Maybe

Bob, Two questions - and thanks for your comments. I am the guilty one for setting this hare running. Would not the the best of both worlds be a system that allows you to select both the

Alan, I made the web site but did not check with every browser. There probably is a problem. What web browser are you using. I'll check it out on my end. Bob Piatek

Hey Bob, I wonder if it just my computer, but there are several areas in this link where text is covered by other text making it nearly impoossible to read. Alan --- Bob Piatek <bobtek@...>

This is an interesting thread. Though I've gotten in late on the discussion, a few points come to mind: 1) Although a guide camera may be able to take exposures as short as 20mS, this will result

Actually, the SSAG is based on a relatively inexpensive CMOS imager, not a CCD. I don't know if Orion used it in a previous product. I believe the Starfish guider by Fishcamp Engineering uses the

Hi Murray, To answer your question, the main reason for allowing short exposures is for non-astro imaging. The cmos imaging and associated driver chips are general purpose and marketed for all sorts

The Orion SSAG is actually a repackaged version of an older CCD camera. I have seen some stunning views of the moon taken with it - so I can only assume that it can be an effective CCD. More than

Can this camera work like a webcam and capture many frames per second to do planet imaging? Just a thought. Larry calculation. autoguider has the ability to sample as often as up to 20 times

Hi Gerald, I received with the printed manual a small sheet of paper with title "Special Notice to Mach1GTO Owners". This says that : - The keypad is set to 1200GTO. - The parameters for Mach1GTO,

David and Roy, I think that you have answered my question about why the fast rates are available - the are to do with mirror corrections rather than mounts. This is similar to modern tank sights

Kurt, I do not have a problem with the maths - that is a straightforward calculation. What I do have a question about is why the software in the autoguider has the ability to sample as often as up

Thank you very much, was having a hard time finding it in the normal documentation. Gedas http://gedas.cc http://www.w8bya.com

Can someone tell me the RA period (seconds) for the 900GTO please? Gedas http://gedas.cc http://www.w8bya.com

Well, it may in fact offer you that choice, but it does not mean you should do that .... There are MANY mounts that couldn't react that often anyway ... I typically use 1-2 sec exposures with the

My hand controller on my Mach! under mount selection lists as options 400, 600, 900, 1200, but not Mach 1. Which one should I select ? Does it make a difference ?

The old Ao-7 was really working to do it at 20 times a second much less a 50 times per second a 20 ms exposure time would infer. It was used to reduce seeing errors but it cannot be used in larger

That's good to know. Thanks, Bill
