Re: Lubrication interval

Lubrication intervals are dependant on usage and the environment the mount operates in. Even if the mount is little used and is stored inside, the grease still dries out. I just re greased my lightly used 2009 AP 900 GOTO last year. In hind sight, should have done it years before. Grease and your labour are cheap. Repairs are not!

That said, what is the recommended lubrication interval?  The mount has been stored indoors in a temperature range of 65 to 80 degrees.

Does A-P have a recommended lube kit and where might I find the instructions on how to do this properly?

Thanks for any and all answers.

Thanks Don. I tore in to it after my first post and got if fixed. I did basically what you said. The middle gear has a hex bolt behind it that controls how much it is meshed with the worm gear.

I just hope I got it tensioned correctly. Sounds normal under slew, but I'm a little concerned about my pec curve. I'll follow up with the A-P folks tomorrow, but for now I'm up and running.

You will have to re-do your PE curve. It's really quite easy with PEMPro.

There have been a few threads on this in the past.

For example,

https://ap-gto.groups.io/g/main/message/59222

Search for secret sauce and for Aeroshell

The former is an A-P product, the latter is a Shell product

I beleive the suggested interval is one to 2 years, but defer to A-P.

Getting the old grease off and setting the gear meshes properly are the only annoying parts of the process. I think there is a YouTube video of a guy doing it exactly. Just watch that and you are good to go. It's very straight forward.





Thanks,

Hi Geoff

Try looking on the Astro-Physics web site. They have a lot of information in their Support section. There is a collection of documentation for their legacy products there. I don't know if the 900 mount is there, but that is likely the best place to start.

George at Astro-Physics is also a good source of information.

When was the last time you cleaned and re lubed the RA and Dec gear trains. If it has been awhile I would service the gear boxes and worm gears. AP has a very nice grease kit. Maybe Marj can send you one. Everyone other Marj, Rolland and Karen are off because of Covid2.

Take off the nylon gear and and the aluminum gear underneath. Have a look at the small gear underneath the big aluminum gear. Could be that small gear is detached from the larger aluminum one. Might be a set screw is loose. In any case have a look to see what's going on.

Short version, I had a small 3-step kitchen ladder near my scope that I had been up and down a hundred times working on collimation. Tonight I went to fire off a pointing model and forgot about the ladder. The very end of my camera fan housing clipped the top of the ladder and I got a motor stall. I removed the ladder, power cycled, and tried to send it to park 3. Only the dec axis moves, and RA axis made strange sound but didn't budge. I removed to gear box side cover and the motor shaft and middle spur gear are turning when slewing and tracking. But the worm spur gear (the furthest to the left and most inward gear when looking at the gear box) is not being engaged. It seems there is a tiny gear behind and on the shaft of the middle gear that is not engaging the larger worm gear. It is barely making contact as I can hear the gears touching each other as they turn. 

Did I just trash something, or can this be readjusted? Dropbox link to short video.

All US government sites (that includes NASA sites) must have been made TLS-only by the end of CY 2016.

In addition to that, TLS 1.1 or higher (such as the newer TLS 1.2) are the only versions these sites are allowed to speak. TLS 1.0 is considered obsolete and insecure. This can cause problems on Windows 7 machines that don't have a certain patch installed and registry change made... but if you're still running Windows 7 (or older), you're lost in the forest anyway :D (yes Windows 7 is broke, and yes you ought to fix it... by updating.)

I have no idea why it would not open on your computer. It is probably related to a problematic Windows update.

Mach2 and Horizons

Terri Zittritsch
 

Last night I was able to image for 6 hours or so, including some imaging of  Atlas C/2019 Y4.    I used the opportunity to try out the Horizons software, so I downloaded the ephemeris data for Atlas.   I did a careful polar alignment, and after imaging a few targets, horizons put Atlas in the very middle of my imaging window, and it worked perfectly.     It tracked Atlas and kept it in the middle of my screen and on longer exposures of a minute or more I could see the stars start to elongate.    For image processing, I'm not entirely sure if it's easier tracking on the comet or guiding on a star.   After marveling on how well the comet was being tracked and stayed in the middle of my imaging screen, I decided for imaging that I'd guide on a star and do the post processing in this way, especially since I had a mono-camera on the scope.  I don't actually know if it makes a difference or not, but know I have a bit of processing to do based on past experience.   I really should have put a color camera on for this.. as I know I'm going to have a lot of processing to do!

Also, not sure if this is just normal for an A-P mount to have this kind of repeatability and precision, or if this is attributed to the mach2 with encoders.   After my very first plate solve, subsequent solves seem to go very fast.    Very confidence inspiring, even with terrible seeing.
