Yup. I get that. I just hit this noise situation after adjusting the worms for backlash. I think I figured it out though. The worm adjustment was too tight. When I loosened it up a bit (by turning the

#Guiding

I've been trying to isolate some issues guiding my C11 on AP900 that look like might be backlash (strangely... in RA). I just re-seated my RA worm (I did this 5 or so years ago). I just noticed that w

Hi George, I put the photo in an album called 'setscrew'. Not sure how to reference a photo on the forum here. It' actually the little setscrew that is visible through a hole inside the connector as y

Does anyone know what the length and thread of the following set screw is: https://ap-gto.groups.io/g/main/photo/274817/3424920?p=Created%2C%2C%2C20%2C2%2C0%2C0 It's part of the Y cable. I lost it yea

Sigh. Off topic, and I didn't want to start a Mac/PC war, or proprietary/open-standards war, just solve a problem, but let's put the record straight. Parallels is virtualization software that runs on

Do you know if anyone has tried Pempro under Parallels? It's quite an impressive virtualization package, and I would be very surprised if it didn't work. Runs Windows applications side by side with Ma

I haven't checked yet, but my gut is that the piece that is still in there is not extraordinarily tight. I don't think it broke due to tightening (I don't keep them that tight). I think what happened

Indeed the problem is bad... that part I'm holding is supposed to be at least 3/4 of an inch long. The rest is in the mount. Pete has used the pilot punch recipes > > > > > (http://food.aol.com/top-ra

Maybe a picture is indeed worth 1000 words... Here is a shot of the broken knob: http://www.santangeli.net/knob.jpg As you can see, the device is actually a hollow threaded aluminum tube with the knob

Good suggestion. I was thinking about something like this. Pete which is a assistant hold a hole to may be necessary the

Unfortunately, the piece that remains in the mount is 3mm INSIDE the casting (the knob came off with 5mm - enough to leave the rest truely embedded). Pete

Sadly, while setting up today in my yard, I went to tighten one of my RA clutch knobs on my AP900 and it snapped off in my hand. It broke off about 5mm down, so that I can just see about 2 mm of the b

Thanks! I just did an archive search, and found an interesting thread. It seems that some people had issues with power cables that lead to runaway slewing. I *have* been having occasional power cable

I never run above 600. I seem to remember it happens when I'm centering, so anything 64x and up. It's a scary/startling enough thing when it happens that I've never let it run forever just to see what

Sorry, I guess I'm not being clear about the setup. - The focusser is a JMI DXF3M with built in motor. - The motor is plugged into the AP900. - The focus commands are being generated by FocusMax, whic

It's a simple JMI focus motor plugged into the AP900, then controlled via the mount and the ASCOM driver. It *should* work with focusMax. Pete

For a few years my AP900 has shown an odd behaviour with slewing manually with the keypad. Occasionally, when I release a direction button, it doesn't stop, but just keeps on going. I've been meaning

Different strokes for different folks. I personally find narrow band images pretty unattractive. But I have no ambitions to do science, which is difficult, but clearly possible for amateurs - just ask

Geometry seems to count as much as weight for mount capacity - my guess is that a folded scope like the RCOS would be fine, I believe because the tube length is not that big in comparision to some oth

Just thought I'd post a quick link here to a project I recently completed. Many months ago I had an idea to create a large, lightweight scope that could go on my AP900 mount. I wanted to test out some
