Very nice. We’ll done sir.

Will use Loctite if it comes off again. I tightened it up like what had posted earlier and by only tightening by 1/8 turn, the knobs haven’t come off ... yet. cytan Sent from Yahoo Mail for iPad

Wow, that’s a beauty! Thanks for sharing it with us! Karen AP

Hello I like to share one of the difficult targets I acquired recently. This Mach2GTO was tracking (20 minutes guiding) my target very well just 15 degrees above the horizon. No modeling this time due

Cytan, Nothing against your super-human strength claim, but I’d say your knobs weren’t properly done. I just looked up red thread lock specs on both LocTite’s website and Permatex’s

Cytan, We won’t pick a fight with you! <G> Seriously, it is an easy fix…add a drop of red Loctite and wait at least 24 hours and they will be fixed. Regards, George George

Speaking of “requirements”… What’s the thought on using APPM with a non-permanent setup? Fwiw, I’m using the mach2 now with an st8300m + fs128 at about 1040mm focal length and am

Then I'm really stronger than I look :) I had two bolts that that came off the knobs. cytan

And red thread-lock needs temperatures above 600° F to start loosening up. And my experience with the stuff is that it lasts for decades. I have a trailer hitch that’s been outside for 20 years

Bryan, Red Loctite is used. One in a thousand will break loose when overtightened. Regards, George George Whitney Astro-Physics, Inc. Phone: 815-222-6538 (direct line) Phone:

I wonder if A-P did use Loctite, then they consciously used blue Loctite, rather than red to ensure that, if needed, the Allen bolt could be removed. Red takes very high temps to release. Bryan

Thanks Robert. So Loctite would've been used originally by AP in manufacturing? I guess it degrades over time. The mount had been outside too for a few days (under a Telegizmos 365 cover) in some heat

Ray's APCC/APPM on-line manual is a great place to start. https://www.siriusimaging.com/Help/APCC/index.html There is a specific section for APPM that I used to get everything set up. -- Dean

Ray has also created a YouTube video for APPM. It’s intended for use with Sequence Generator Pro for camera control but essentially highlights the setup. Following the steps makes it quite simple.

Ted There have been a couple recent threads on building APPM models during bright moon times. Here is one. https://ap-gto.groups.io/g/main/topic/81388396 I do not think there is a max limit on focal

I would appreciate some guidance on how to set up APPM. I have an AP 1100GTO on an ATS pier that has been stabilized with three ratchet ropes attached to steel anchors imbedded 4 inches into a

Jack, Reliability is more a function of how you set a system up, than of the connection method itself. In your observatory, you probably have an issue with something like a driver, faulty cable,

I have my AP1600 with CP4 connected to the observatory computer using a Serial cable and USB to Serial adapter. I use SkyTools to connect to and control the mount. Occasionally I get an error

Same problem happened last night. Thanks to all for the help. Yes, I'm using TCP. Ray has looked at my logs and thinks it is a timing issue. My data goes from mount via Cat6 to LAN switch via fiber
