Hello Atlas owners.

I was hoping to hear from some of you regarding your weight capacity. The mount is listed for 40lbs I know, but some of the reviewers state they've pushed beyond that, and some say they feel confident this mount could swing twice that.

If you own an Atlas GOTO, or EQ6, would you feel confident or have you imaged with say 50lbs (C11, piggy backed refractor, DSLR, 2" Diag, etc)?

Nope.

You'd have a heck of a time counterbalancing a load like that on an Atlas.

I pushed my atlas with a 10"F4 nuwt, 80mm guide scope and cameras, but a C11???

Someone in my Astro club thought that he heard some owners of this mount were using it with a C14. A 50 pound scope with about 50 pounds of counterweights? Seems hard to believe, although I never saw it in person.

Well, the C11 comes in at 30lbs with the basic setup on it. There are several reviews for the Atlas on Orion who claim the mount swings a C11 with ease and could handle more. I'd be using 2" accessories for visual, and am looking into piggy-backing an 80mm and DSLR, so I figure my range would be 40-50 lbs.

By the way, what is the standard saddle on the Atlas, Losmandy or Vixen? I was told Losmandy, but it sure looks like a Vixen in images I've seen.

I used a 12" Meade LX200 OTA, a 60mm f/4 guider with SSAG and a SBIG ST-7 all at the same time. Tracked and guided fine taking a picture of a 15th magnitude asteroid. This was close to or above it's limit.

The saddle is Vixen type.

That was the case 2 or 3 years ago then they started shipping the mount with 2 separate saddles: a Losmandy and a Vixen. More recently they have been shipped with a single saddle that will take both Losmandy & Vixen dovetails.

Bonus! Good to know, thank you.

That's interesting. Do you recall the weight of that setup?

I stand corrected. Thanks for the update.

Somewhere between 40-45lbs. Not sure exactly. It was just over 40lbs.

It used a ADM mini bar bolted to a vixen bar for mounting. The guider was mounted on a 1/4-20 thread mount in the finder bracket to keep weight down. The ST7 weighed more than the guide scope and SSAG. I used three 11 lbs and one 3.5 lb weights and it balanced just fine. I have since upgraded my Atlas to the wider losmandy and the 12" OTA also has a losmandy bar. I'll be testing this arrangment again next time I can get out. I'll weigh some of the items later.
