Re: Mach 1 Grease

I was also apprehensive about re-greasing but the written instructions were on target for a smooth process. I highly recommend taking telescopes and weights off before the process. 
The hardest part was getting the gear box separated but it was on my mount for four years. I was also impressed with PemPro easily returning PEC to a suitable status.

Just sell me one and I'll happily volonteer to make an entire step by step video on it ! :D

(I'm actually not kidding... These Mach1 are so rare and hard to get in Canada. If anyone interested to sell, please PM me.)

As long as there is an ASCOM driver for your camera, you can eliminate the guiding cable by using PHD2.  Data AND guide commands are sent via the data cable.

This is the only video I found:

However, I followed the written instructions from George/AP rather than the video.  It is easy to do, but best to work slowly and to be thorough.

I concur.

I read the instructions and being a klutz, I'm actually a little leery about doing the regrease. Can some one make a video? It'll help a lot.

I am in Australia, and a number of trips into the "outback" have no doubt been the problem. Very hot and a very fine red dust which just coats everything.

Got autoguider movement to work in SkyX, I goofed and had guiding set for Direct instead of Pulse Guide in the profile.  It will be nice not to need that autoguiding cable anymore.  Supposed to be clear so hopefully this will be a wrap so I can get down to business.  
Its not clear often in WI like it is down in TX so I call it a win.

Re: AP1600 GTO CP4

Actually, now I remember why I needed to use the ST4 relays because with my current setup with STXL6303 and FW8 autoguider, I can't run both at the same time with CCDOps.  I believe I stumbled onto this somewhere on this site.  I do have another guide CCD but would need to either piggyback a guidescope or buy the software that allows concurrent connections to my main ccd and filter wheel ccd.  Unless, if it is possible to connect my 6303 main to ethernet and use the usb connection for the FW guide ccd.

I am sure that someone else has figured this out but I haven't found the exact recipe yet.

CS,

Joe

Forget about this question.  I am going to try out directguiding, sorry I guess I have been under a rock for so many years.

I had a successful trial using APPM for the first time (just purchased software).  I did a simple model first of 25 points; I did a small model first to understand how it works.  Note, prior to this model the mount tracks very well as I did polar / PEM via.  Of the 25 points, I had two failures.  When model was loaded into APCC and I had Pointing/Tracking Correction I was getting significant tracking issues with the Tracking Correction turned on.  Pointing worked very well.

I just have one question.  I have been trying to get autoguiding to work and narrowed it down to the autoguider port in my CP4 using the test on the support page.  I don't see any movement when shorting the different wires so my question is if this is something that can get repaired if I send it in or if I have to buy a new CP4.

Call me old school but I haven't had any issues with my Mach1 or AP1100 using the ST4 port but I bought this AP1600 used from Company X so I wonder if it was dead on arrival because I tried different cables and different CCD cameras both SBIG and both currently work on my AP1100 and the fact that the test results in no movement.

Though, it might be worth mentioning that when I first powered it up, my keypad wouldn't boot and but Howard walked me though reseating the comms board on the main board and I was good to go.  I have no idea if this would of caused the autoguider port to go bad but next time I will just buy a new mount so I can blame myself for things not working as I highly doubt it was anything I did but hard to prove now after the fact.

Any ideas or something else to try before I buy an new CP4 or send in for repair?  

Clear skies,
Joe


Re: What are the advantages of the APCC Pro

Hey again Mike,
Wow! that is a gap between your mount and pier. Sorry about that. My permanent pier in my observatory was originally built for an RCX400 several years ago. I got lucky and snagged a "free" piece of 12" square tubing with 1/2" wall thickness that I turned into a pier. I used double 1/2" plates, both 22" square, on top of the square pipe. One welded on and the other mounted on 3/4" bolts in each corner for adjustability and leveling. It has worked great and VERY stable. I swear I could run into it with my truck and barely make it move. For the AP1100 mount I needed a a vertical extension for clearance so I took a 14" long piece of 8" pipe and made it, with another 1/2" plate welded on top of that; the whole thing then bolts down on top of the original pier. So AP's flat plate adapter is bolted on top of the pile!

Re: What are the advantages of the APCC Pro

Steve C. Mitchell, Sr., O.D.
 

Hey Mike,
The pointing accuracy probably isn't a real big deal, as you say, but improved tracking MIGHT be an advantage. IF it would improve the tracking so it doesn't "creep" over time and it could make auto-guiding better, it might be worth it. Taking unguided 10 minute images doesn't pull my chain too much. Guiding seems to work fairly well with my QSI683 with built in OAG mounted on my 12" Meade ACF with piggybacked 80mm F5.6 refactor for wide-field work; so I don't see the advantage of unguided capability.
I can certainly understand the issue with cash flow in this crazy unemployment time! I'm a practicing Optometrist, who's had nothing but emergency patients for almost two months now trying to keep all my employees on the payroll without cash flow has been quite difficult enough, but I don't get anything without patients. Fortunately we we released for full time practice this week here in Kansas. Hopefully everyone will be set free again REAL SOON.
Improved tracking, hmmmm....
Steve

Hi George,

   How many hours of use do you recommend between regreasing? I do log the hours that my mounts operate, so a time interval would be useful. Or how can I tell whether the mount needs to be regreased?

 

Thanks!
