New mount + future
« on: December 27, 2017, 12:48:58 PM »
Hi all,

I'm looking for a new mount and could use your insight. At this time I don't have an observatory. I will be using the telescope in my backyard.

In the future I will probably build an observatory and put the mount on a pier.

I am a refractor guy and have now a 120 F7.5. I might jump up to a 140 F7 or 152 F8 at the biggest.

I absolutely hate wiggles and want to purchase a mount that will minimize (or eradicate) these now and for future use.

I am a visual user with really no interest in photography except for the occasional cell phone shot or digiscoping.

I absolutely want tracking and goto. I am intrigued with using Sky Safari via bluetooth or wi-fi to control the mount.

So, what does the collective say?

Do you have a price range? I'm a big fan of the Losmandys for that sort of thing: great mechanicals, good on the gotos, there's some new ones that just came out, etc. Still, it's a little pricier than say the iOptron CEM60 (another great mount for what you're doing, and, they're on sale right now!), but that would be my first choice.

Yeah, I'm thinking not more than $4k

A variety of mounts would be good for you.

I would probably get a CGX, assuming you can lift it. The G11 is certainly a consideration, and I would have recommended it if you were interested in AP or if you couldn't lift the CGX.

Even a CGEM II or an Atlas would handle most scopes you mention, with a caution when it comes to the 152 F/8. That has a lot of moment arm, and although the CGEM II or Atlas should handle it except with heavy wind, the CGX would be better.

You can always improve the steadiness of refractors, if you hate wiggles.

1) Hargreaves strut.
2) Motorized focuser (makes a HUGE difference, eliminating all wiggles from focusing. And they're pretty inexpensive nowadays (you don't need a stepper)).
3) better dovetail saddle and longer dovetail with quality rings.

You took me back to my visual days

The iOptron CEM60 is on sale for a shade under $2200, I think (double-check); the Losmandy GM811G (rated to 50lbs) is an eyelash under $3000 with the good folding tripod, and the G11GT without tripod is $3995, while the one with tripod is $4,395, but that sucker takes 75lb payloads.

Atlas Pro AZ/EQ-G. Best investment in this hobby so far for me. Great rig.

I own both a CGEM and a G11 Gemini 1 currently. When you consider payload take anything from oneof the Asian builders with a grain of salt compared to a Losmandy (or anything larger like A-P or Paramount). I have owned a total of 3 G11s and anA-P 800. G11 will carry a 6" APO with ease for both visual or imaging. Not sure I'd trust my CGEM to do that but since downsizing some due to age it does handle my SV-115T fine.

I would go with the Losmandy G11G - it's a G11 mount with Gemini 2 GoTo System. Make sure to get the new one that Losmandy lists with: "Servo Motors Tucked In (Inboard of Mount). and One Piece Worm Block Assembly," and includes the folding HD tripod. It lists for $3295 on the Losmandy site.

+1 to all of the above. I have a CEM60, whose advantage is light weight. If you're going to be using an observatory, that advantage fades. But you will appreciate it right now.

So, how's the ioptron's quality? I've never seen, nor worked with one.

I have owned an ioptron and seen seen 3 or 4 in use in the field and everyone had issue......seems their quality control and build quality is very poor.

I know there are users that have ok units but i recommend doing your research if you are considering them.

I have seen quite a few Losmandy mounts that seem to be reliable especially after a "tune up"

A secondhand Tak EM200 would be good if you can find one.

One critical component is the Tripod !!........a bad tripod can make a good mount look much worse ....introducing vibrations etc......this is often overlooked so budget for a high quality tripod like a Berlebach, Avalon TPOD, Losmandy HD, Tak or something along those lines.

I've never had a problem with either two of the iOptrons I've had, the three I've tested, or heard of any from the five people who have them at my site. Their service is fast and they've responded to me over weekends as well. I've never used the 25's, but the 30's, 45's and 60's have been excellent within the specs they are advertised to have. For what it's worth.

I've owned the ZEQ25, and now own a CEM60 and a Skytracker V2. FWIW, here's my opinion.

iOptron has released some mounts before all the bugs were worked out. It has cost them in reputation. Their second generation mounts, or 1st generation mounts that have been out for a while are good. I've been inside my CEM60 (for my own reasons, mostly), it seems very well assembled.

I don't recommend buying a used CEM60, some early examples had play in RA. iOptron has a service bulletin, but it's nothing I'd want to do myself. Pretty sure iOptron (Boston) can do the work, the big cost would be shipping.

I waited until reports indicated all the bugs were gone before I bought my CEM60. Ordered direct from Boston, asked for one that had recently been shipped over. Did not want a fixed return or one that had been sitting on a vendor's shelf.

Haven't seen any complaints about recent CEM60s. Haven't had any.

Thanks all, looks like I'm getting a used G-11 Gemini 2 with some goodies.

G-11's are great. Heck of a mount, and the support is good, too, if you have questions.
