Pushing the Mach1's AP Limits...
      #3767471 - 04/25/10 02:24 PM

Has anyone pushed the Mach1's limits to 50-55 lbs. for AP in a SCT configuration with satifactory results?

I plan to use a 12" LX200R, 2" TCF-Si, 2" Pyxis, 2" IFW, and ST-8300M on it...

Clear skies!

I don't know, but at NEAF Roland said it shouldn't have a problem with a C14. I think I prefer the AP900 though for that.

Of course, if you're trying to minimize mount stress, one might note that Meade builds heavy, so you can get extra stability by switching to Celestron OTA's.

For visual it shouldn't be a problem. The moment/arm is not bad since it is a "short" scope. I use a 160mm for visual use, which has a lot longer moment/arm and is more work for the mount than a short moment/arm, with no problems. This is also on the wooden AP tripod.

Just curious if on a tripod or a permanent pier? both? I have no experience data for your post question but have been thinking it would be fine with something like a C11 or AT 10"RC and small guide scope. Agree that you might want to look at the optional CW bar and weights. I've only had mine a week so my experience is extremely limited - also using a 160 apo as above.

Well, mine was just ordered for immediate availability (delivery in about a week.) All accessories are AP: portable pier (48"), CW bar upgrade (for compatibility with my AP1200), CWs, dovetail, and trays (2 of each). I plan to use the mount for the LX200R or NP127is...

Enjoy that Mach1! I got one because I didn't want my imaging gear to hog all the features of an AP mount!

Clear skies!

Nice mount. Congrats! Post up some pics when it arrives and let us know how it handles everything.

I had mine working fine with an AP 155 EDF, 4 inch FF, Proline CCD, PDF and filter wheel. About 55 pounds total. Had six 9 lb counterweights. Worked fine with AP and guiding. I think this is very close to the limit...

The Mach 1 is a HELL of a mount but at the focal length your looking at using I think even the AP would be tested to it's limit.

I note you say "had" and now you have a AP 900

This is true, Always looking to hang something bigger and heavier on the mount Had the opportunity to trade the Mach1 for an AP900, I'll have to admit I miss the Mach1 a bit. Here is a pic I took with 55 lbs and a long refractor on the Mach1:

And here is the little fellow waiting for dark.

I will have to agree with the comment above, I was shooting at a FL of 1178mm. The focal length you are looking at will probably be too much.

Excellent, Jim! That gives me some reassurance...

I have a 10" LX200R just in case I had "issues" with the 12". Now, I believe I can sell the 10", rest-assured!

Clear skies!

Me, too.

I planned for the Mach1 to be my ultimate mount and that's how I sold it to the CFO. Based on how much weight you have used on it, looks like my plans are good. There is simply no way I could pile any more weight on it than you have.

Thanks for the info and pictures.

Cheers,

Ron

I had it for about two years and absolutely loved it. The uncorrected PE was <3 arc-sec, I could do 10 min unguided . The pointing accuracy was awesome, really miss it more than a bit, but the AP900 is pretty nice too, just need to get used to it it I suppose. Only had the AP900 for about three weeks and just got it polar alighed last night and did PEMPRO PEC training and got the PE down from 4.5 arc-sec to a.75 arc-sec, so I think it is a winner too.

I also traded my Mach1 for a 900 since I wanted to be able to use my TOA-150 with either mount. Would have been fine for visual but maybe not best for imaging.

Anyways, the Mach1 really is a great mount and mine guided extremely well, prehaps better than the 1200 even. If I ever downsize I will get another one for sure.
