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

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.

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!

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.

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.

I have an older AP1600 mount that does not have the quick release option for the RA and Dec gears.  Is Astro-Physics going to release an upgrade kit for older mounts to allow for quick un-meshing of the gears?  I have a friend who has the new version of the mount, and he can easily un-mesh the gears and precisely balance the mount.  In my case, even with the clutches fully loosened, there remains so much resistance to movement, that achieving a precise balance is impossible.  I use an electronic fish scale to try to achieve balance, but it takes over 10# of force to get the mount to move in either direction with the clutch screws loosened.  Is this normal?

Re: Mach2 - Elongated stars

Ray Gralak
 

Yanhze,

Where is ASCOM driver log? I dont use APCC, I use SGPro.
The AP V2 ASCOM driver, which you must use with SGPro, comes with a log zipper utility called "AP Log Zipper". You should be able to find it from the Windows start menu by typing that name. The utility will grab the log files for X number of days in the past. If you can't find it, you probably didn't install it when you installed the AP V2 driver. In that case, just reinstall the AP V2 driver and select the option to install it.

BTW, you can use APCC with SGPro. In fact, it is recommended. An APCC Pro license comes with your Mach2 mount, but you must contact A-P to get it.

I have just joined this group, as I am researching buying my first PREMIUM mount.

Considering it will be a big expenditure for me, I wanted to make a good and informed decision.

Seeing Roland's response here on this thread, and his engagement with his customers who have already parted with their hard earned money is very inspiring and commands respect. I am pleasantly surprised at te level of engagement and support!

:)

I have been researching buying either an AP vs another premium European brand mount.

I had requested to join the European brand's forums to see user's and owner's experiences in the field, and the level of support they are receiving. I have not been impressed.

Just reading through this thread has completely sold me on AP. I'm glad I followed the advice on Cloudy Nights to join this group!

Too bad that I live in the UK!
