I'm conflicted and need your help: iOptron or Losmandy
« on: December 28, 2017, 07:21:15 PM »
I have an iOptron IEQ45 pro in my obs and I may have an opportunity to purchase a used GM811G. I'm not unhappy with the IEQ45, but I've heard lots of praise for Losmandy mounts over the years. I've also heard they can by finicky and higher maintenance. My use is guided AP. I'm seeking opinions. What to do?

I love my Gemini-2 and my GM8. The best part? When I break something or I just need advice, Scott and his crew are a phone call away and they're very good.

The losmandy community on Yahoo! Groups is really good too.

Oh, and Losmandy likes to make his stuff upgradeable. If I wanted to make my old GM8 into the new version with tucked in parts, I'd just have to buy some hardware and it'd work. You can't do that with Ioptron.

And don't look at the threads of people having trouble. Often times people seem to cut their teeth on the chinese mounts and then think they're more mechanical than they are when they get their GM8/11. They start tinkering, and that is the root cause of their issues.

As an example,Hilmi had several long threads about his G11. It turned out ultimately that he had just got it out of wack and couldn't get it back. He shipped it back to Losmandy, got the same mount back, and it was fine.

Oh, and American. They're beautifully machined, well thought out... If you can't afford AP, it's the best you can do.

Good luck,
Chris

Having owned examples of both I have no real complaints with Ioptron. That said its really no contest. Losmandy wins hands down.

Seems a sideways move, unless your iEQ45 is not working correctly and you are throwing away subs.

I just got my 811g and its pretty nice. I also looked at the CEM60 which is cheaper. The one thing I thought might have been useful with the CEM60 was the heated HC. The one thing that turned me off about the CEM60 was how the worms work and from many sources I heard they are tough to get used to.

Balancing on the 811g is super easy, the axis move with your finger when the clutches are loosened. You can connect with ethernet or usb and I use the usb connection to point the scope with Stellarium.

At the end of the day I see Losmandy mounts going up for sale that are 20 years old, people are still getting $2000+ for the mount after 20 years. The resale value speaks the most to me. I would like my mount to last for about 30 years and I think the 811g just might do it.

I wouldn't say higher maintenance is at all accurate for Losmandy mounts. Most of the discussions in this forum pertaining to this family of mounts relate to backlash in the worm drives.
Particularly with respect to the older worm block mounting methods, this is an area where customers can make adjustments which can improve performance of the mount. The problem is that there are many degrees of freedom once the block mounting screws are loosened, so it's also very easy to misadjust the mechanism and make things worse. And, as Chris noted above, not everyone who attempts to make things better is adequately skilled for the task.

 If you're looking for the absolute best performance and have the patience and a reasonable level of mechanical aptitude, you can probably adjust almost any Losmandy mount to be the equal of anything else in its price range. I've found it much easier with my mounts to adjust them to have just a little bit of backlash and accommodate the consequences through balance and mount modeling. Or simply leave things be if they're working. I bought a used G-11 five years ago and haven't loosened a screw since it arrived. To my knowledge, the original owner did the same. That mount was used in my observatory for a couple of years without any issues whatsoever.

 Overall, the mechanical design and manufacturing quality of these mounts is very good in their price range. A G-11 is not a Mach 1, but it's also not an AVX. I have no experience with iOptron mounts, so I have no basis for comparison to that line.

Hands down Losmandy wins on many fronts, quality, customer service, longevity, support, and the list goes on. While there are many happy iOptron owners out there look at the two side by side and then lets talk 10 years from now and see which one is still working just fine.

That's sort of a lateral with an upward trend kinda thing. New, on a level playing field, I'm going with the Losmandy, but you're in an obsy, already set up, and your iEQ45 Pro is working pretty well. If you're not throwing out subs (which I found you don't really do with the 45's, generally), you're not going to get much more from the Losmandy. BUT, if you're changing something, like going for really long subs in narrowband, and you're finding the 45 can't cut it, then you might try the Losmandy. Losmandys are kinda that middle ground between the best of the Chinese-made and the real step up: the big boys like AP, Bisque, and then the exotics like 10Micron and ASA.

I've gotten similar imaging results from both 45's and Losmandys, with the Losmandys being much better looking.

A fair and reasonable assessment I think! If you are happy, keep taking pictures, if you want something a little more, then Losmandy makes a good, solid mount worth considering.
