I have a 14.5 iDK (33 kg) and a 130 apo (12 kg) on an 1100 mount.  No problems as far as the mount.

I balance by measuring the power draw in each axis.  https://www.astro-physics.com/cabppwm

Thanks, mine arrived late December 2017 so it's got some time to go.

It was original from 2008, so that factory grease was at least 12 years old. The worm grease was alright but the worm and spur gear grease was noticeably solidified and obviously in need of refreshing. Doing this exercise also let me discover some corrosion on one of the brass spur gear shoulder screws. All in all I learned a bit about the mount and feel pretty confident in servicing it or the 1100 that I have on order myself.

Dale,

How long had you run your mount before changing the grease. The original grease still looks to be in good condition.

I have had my C14 and 130 on my 1100 and also on my 900.

However for a C14 and a 160, personally I would go for the 1600.

Hello all!

I'll soon receive a brand new AP1100 mount which I'll be using for my C14 EdgeHD and AP160 scopes.
Is it crazy to even consider mounting these two OTAs side by side on the AP1100? I should be right within the weight limit, including with my STT8300 CCD camera... (I realize the challenge of balancing such a monster setup).

Thanks!

Good idea to re-do the PE correction curve after re-doing the grease. It may have changed due to wear from the previous time you did it.

I'm not sure what the big deal is, John. Hardcopy instructions are included with the $25 grease kit that you can order over the phone from Astro-Physics. The paper instructions are certainly adequate alone; I don't think a video would add much besides just parroting what they say.

Here's my pictorial from when I regreased my Mach1 last summer.

Re: How to Re-grease a Mach1 with Auto-Adjust Motor Boxes?

Bill Long
 

Just to be clear, my issue was completely caused by me. The negative lead popped off of the motor when I was removing the motor box from the mount. They even warn you to be careful and I messed it up. 🙂 

So, if you follow the directions very carefully it should come out fine. The rest of the work went through with no issues. I sent the motor back and AP fixed it and shipped it back to me. All clear and good now!

Hi Bill.

Thank you for sharing your experience. I know you to be a very knowledgeable amateur astronomer based on your many useful and helpful post on the forum. If someone with your level expertise struggled with this re-greasing process the first time, to point of actually damaging the mount, does not give me warm and fuzzys about attempting the process myself. Given the recommendation that all owners of AP mounts should be performing this maintenance ever 2 - 5 years would indicate a strong demand for clear and concise instructions for each mount. I am sure we could all call George and have him walk us through the process step by step, but it would seem easier (for AP) if we could just get a step-by-step guide or even better a YouTube Video showing each step in detail. I am going to hold off with re-greasing my Mach1 from 2016 for now until hopefully some better instructions come along. 

Thanks again for sharing your experience.

Re: AP1100 Notification Suggestions

Mark Lamb
 

George just emailed me to clarify the 119FSA-FP (and I assume 119FP) is only for ATS piers and will not interface with the Losmandy HD tripod.

The part needed is 
LT2APM, which the 119FSA would attach to.  AP1100 => 119FSA =>  LT2APM  => Losmandy MA => Losmandy HD tripod

Or remove the 
Losmandy MA and attach the 119FSA, which might require drilling/tapping extra holes.  AP1100 => 119FSA  => Losmandy HD tripod


Re: AP1100 Notification Suggestions

Mark Lamb
 

Jeffc,

(Referring to mounting the AP1100 on the Losmandy HD tripod, with MA top.)

Are the pieces you referred to the: 119FSA + 119FP?

A-P also shows a part: 
119FSA-FP that seems to be both pieces bolted together.

Thanks!


Re: Mo videos :)

Andrew J
 

Hi Tony.

Great Videos. Thanks for sharing. A quick question if you don't mind. I have seen it mentioned several times here on the forum, that if someone plans on using a second scope for guiding (rather than an OAG) then ring mounting the guides scope to the primary OTA is not a good idea due to flexure. I heard that it is better to either mount the guide scope directly on the focuser using something like AP's 10 x 60 Vario Finder with Quick Release Guider Bracket Kit. (1060VGKIT) or to use a side-by-side mount like you show in your videos. I am curious if using a side-by-side setup would be a problem inside a dome? I have a 8" ExploraDome and I think the shutter opening is like 27" wide. So I guess as long as the two scopes do not span a distance more than this width then it should be OK. I was just curious if you or anyone else here has experience using a side-by-side in a dome?

Thanks again for sharing the videos. Always exciting to see other AP Mount setups.

Re: How to Re-grease a Mach1 with Auto-Adjust Motor Boxes?

Phillip Klein
 

Hello,
Thought I would share my regrease experience since I recently completed the task on a Mach 1 that I purchased in 2016. Not being naturally mechanically gifted I reviewed  the AP provided directions that describe the process for several mounts. Also, searched the internet for a video and found a useful hint (the longer T shaped Allen wrenches to more easily reach the bolts and provide enough torque to break loose the bolts). I separated the mount and had the grease, Q-Tips, small cloth, gauze, several toothbrushes and was ready to go. None of the photos matched my mount which confused me so I sent George pictures of my mount’s motor boxes and asked for guidance. George’s reply was brief. “Directions for my mount were on page 10” which by the way had no photos.
The regressing was uneventful but sorely needed. The mount slews perceptibly smoother and quieter.
Certainly, I added the note “My mount directions” to page 10.to avoid confusion in the future as I plan to regrease annually. 
I agree the directions can be confusing but I recommend seeking AP technical staff’s input if you are unsure about something. They are always there for you.
Clear skies!
Phillip

It is so easy to install and remove the RAPAS (3 screws) that I think the prudent thing to do would be to remove it after you have polar aligned.
