The stepper motors will hit resonant points if the belt tension is set too high. If you send me an e-mail I will walk you thru setting the belt tension so it doesn't do that. Roland

Hi Roland, Can the Mach2GTO (with AP 16" EAsy balace dovetail on Eagle 6 mount) comfortably handle the below OTA and image train - C14 Edge HD OTA Additional Losmandy Dovetail bar on top of OTA C14

>>>For GPS devices that emit standard NMEA time sentences over a serial (COM) port, there is NMEATime2 ($20) or the older, free version, NMEATime. just for the heck of it, i purchase NMEATime2 and an

Dale Ghent said: One thing to realize is that NMEA time is inherently inaccurate, exacerbated by USB serial delays. Most GPS chips also emit a PPS or 1PPS (1 pulse per second) electrical signal

You just need more leverage than what an allen wrench can provide. Use a longer device, such as a long phillips head screw driver, instead.

Hi guys, I just received the new AP1100 CW shaft adapter with SS insert and I want to replace the existing one without the SS insert. I removed the CW shaft and my telescope and then in the park 3

Ok, cool. Is it a one-per revolution click? No laboring or other funny noises? It may make sense to just do it over again. Jeff

Time syncing is complex enough of a topic that it's best to let dedicated apps which handle the intricacies involved do the driving on this. There are entire professions and academic pursuits based

Hi Bob, It probably will not be a feature of APCC because to set the time on the computer APCC would have to be run "as administrator". That is something we probably would not want to do because then

Jeff, The mount is 5 years old, has spent about 30 weeks in the dusty desert, and has never been re-greased. I seem to recall AP saying mounts should be re-greased every few years. I used the grease

A note on tracking: a 15 second exposure is quite a long time unguided. Especially on the moon which doesn't travel at the sidereal rate. The lunar rate setting on APCC is only approximate since the

I'm really quite surprised that APCC cannot utilise gps time directly. I bought a $10 usb gps and it works well with APCC. When I went looking for the setting in APCC that would allow me to utilise

Daniel Thanks for that explanation. It made sense until you said "aim at an f ratio (i.e., F/D) equal to 5 times the size of a pixel in microns." Can you intuitively explain why? Failing that the

Eric I would bet that there is still something stuck in one of the teeth of that gear. It could be a piece of dried grease. Don Sent from Yahoo Mail for iPad

So after maintenance, you developed an issue. Sounds to me like a problem with your maintenance. Why did you feel you needed to re grease the mount? What symptoms was it displaying?

Nothing wrong with calling AP and nothing wrong with seeing if anyone in our group can help. JimP Get Outlook for iOS

I just re-greased my 1100 and am getting a ticking noise in RA when going west. I took off the gear cover and the noise is coming from the middle (topmost) gear, and occurs once every revolution. I

I thought I'd post this after reading the recent ap-ug "Mach2 vibration & noise issue from the RA axis" thread, in case it would be useful to someone else. I had a little problem the other night,
