when compared to Orion mounts, in carrying capacity, equal to the Skyview Pro or the Sirius:question:.

I have had a 9.25 on my LXD 75. Its fine visually but its much better with the 120MM EON.

I want to put my F15 on the Sirius if it works instead of buying the heavy, for my aging muscles, Atlas.

This is the EON on the LXD 75, an F15 scope, may be too long.

I will say this, my lxd 75 was 84% capable of handling the F15, but it was a struggle.For me and the mount.

How does the EON120 ride on that? Pretty stable?

Abe,

LXD75 handles the EON fine. The EON is light.

I think that the LXD-75 is more comparable overall to the CG-5 ASGT. The Sirius has a similar loading capacity, but mechanically is more sturdy, and, on my opinion, better built.

I believe the LXD-75 is supposed to be similar to both the CG-5 and the Orion SkyView Pro. All of these are clones of the Vixen GP.

I am reading from these comments that the sirius would have more capacity then the LXD75 by a reasonable
percentage. Say 20-30%.

I would agree with your statement.

The Atlas is considered a "Step up" from the EQ-G by Orion (and $250 more), yet would you classify the Atlas and LXD75 as competitors and similar in capability? But the EQ-G has more weight capacity?

Actually, the EQ-G has a 30lb max load while the Atlas has a 40lb max load.

One day when I purchase only one mount, I always thought of myself as getting either an Atlas or CGEM to mount the EON 120 with an 80mm piggyback. I never thought to get the less expensive Sirius EQ-G... and yet Orion sells this exact combination as a kit:

I'm wondering if this combination would handle the added weight of a piggybacked guidescope?

Well thanks all. I wanted to avoid getting the Atlas or the G-8 as this is the only refractor I am going to own so the Sirius is it.

In my opinion, LXD should be better than CG5 because:
1.LXD75 has ball bearings on both RA and DEC, CG5 only on RA
2.LXD75 has reduced slew rate mode which is good for long tubes

I was able to run my 10" F5 #40 reflector on top of it for visual only. After balancing it was running very smoothly.
The only problems I had were:
1. EP too high so I had to stand
2. Goto errors of about 3degree in the worst case
Otherwise tracking and motors were running just fine.

At $475 shipped from Meade outlet, it is a killer deal.

Considering the Sirius costs $350-400 more than the LXD, even on the used market, I would hope it has more capacity.

Well, Sirius costs about twice the LXD75 costs (1150 vs 600). Do you get twice performance? I dont think so.

Three degrees doesn't constitute "better" in my book. My CG5 has placed objects on the small chip of my Stellacam since day one.

I think the goto errors on the LXD75 are due to the *BLEEP*-poor encoder wheels on the motors.

This is why Deep Space Products sells upgraded encoder wheels for the LXD75. :-)

I know they are thin, flimsy, easily damaged and separate from the motors.

I do think the LXD 75 is somewhat better than it used to be, but the last star party I was at a couple of dudes had stripped their 75 down to parade rest to try to deal with slipping transfer gears. :bawling:

Uncle Rod,

The gears were the issue with my LXD75. No matter how I adjusted them they would continue to slip.

Hmmm, 6 years and 2 LXD75's later mine have always given excellent service. Accurate GoTo's require good calibration and drive training, most of the problems I've seen were due to skipping the calibration step. A good power source is a big help as well. The few cases of gears slipping that I've seen were easily fixed with a spot of Locktite on the set screws. At least that has been my experience.

All I want is a portable mount that's goto/tracking PLUS easy enough for grab-n-go without power... take it out back, mount the scope, point and enjoy without power, aligning, or the controller, just like my Vixen porta. Only if I want goto/tracking will I bring the battery out and align it.

But this mount needs to be able to hold anything from a little 6lb 80mm refractor to a big 15lb 5" job with a piggybacked guide scope. The reason is I don't really want to spend twice on two mounts.

But what I'm finding out is you can't have it all... I need to buy a good manual alt-az for grab-n-go like my Vixen porta but one that can handle 15lbs... but then I also need to just bite the bullet and buy an Atlas too.
