I think I need a better mount...
« on: December 27, 2017, 03:17:21 PM »
I set up all my gear the other day in the house, I was mainly trying come up with some sort of cable management system as well as check balance. I noticed if I barely touched the scope, the mount moved (flexed). Now I built a pier outside and I am just waiting on plates. That may cure some of the many many issues I have had, one of the major ones setting up on uneven ground on soft soil.  Nevertheless, the 8" SCT is heavy, the Canon 7D is quite heavy (magnesium and titanium body), the OAG and the focal reducer put me at about 25 lbs on an AVX.

So what mount should I get? CGEM, CGEM-DX, CGEM-DX-L? Something non-Celestron?

What is your budget? What do you want to image? What other kinds of scopes or equipment are you planning on carrying?

I just went through what your going through now. My choice was made a little easier since my back will not handle heavy lifting. The lightest mounts for the capacity are from iOptron. I chose a CEM60 which arrived about 3 weeks ago. With your pier, you might get by for $2300 or so with shipping for the CEM60. I only have a few nights of experience with it, but so far it seems to be handling my 35# load from a 10" astrograph very well. The CEM60 weighs 25 lbs with a rated capacity of 60 lbs.

If you are comfortable with lifting more, there are mounts that will be more economical for you. There was a wait list on the CEM60 just after I ordered mine.

I tried to repost earlier but it failed I guess. I don't see it here.

Overall my budget is $2500 or less. I mainly plan to image whatever I can see.  My view of the sky is somewhat limited, I am sure some might ask me why I even bother to try. Fact is, I don't care much for visual, I want to see it on the big screen on my desk. So imaging gets me there.

I like my AVX. I probably can get short guided subs with it as things are. I hope with the pier I can get closer to 2 minutes but I just don't think its going to happen. I should get plates from Dan's Pier Plates in 3 weeks and I will give it a whirl then. I can just barely see the celestial pole between two tree tops. I am guessing I can get 22-25 minutes with a star to do proper RA drift alignment. My view west is worse, my view east is wrecked by LP. The north star just peeks over the top of my house. I think I can get close on alignment in the dec with a polar scope. With a perfectly level pier with basicly no vibration, and a reasonable PA, I should be able to get some decent short pics.

I guess another part of the story is if my OTA is pointing west I get reasonable guiding and decent 60 second subs. If it is point any other direction, the stars go oblong. My last session out I took 120 60 second subs and only about 20 were satisfactory when pointing at the Iris Nebula.

I know I am pretty new at this but I also recognize I am way past the 50% mark for most mounts in determining weight limits for imaging. In all likelyhood I would keep my AVX and put a small refractor on it for imaging at other sights. I would also need to get another pier plate from Dan's so that's an additional cost.

Most would recommend a Cem 60 or Sirius with that budget. I have owned neither, so I'll let others chime in on those mounts. The Atlas is heavy, but if it stayed on a pier it would handle most anything you can throw at it. You mentioned other sites, so I would go light if remote imaging is in the mix.

I realize this is about your search for a new mount, but just a thought:when imaging from light polluted areas there is always narrowband imaging.

I would suggest a Losmandy G11

Another player is the new Losmandy GM811, it's higher than your budget at $2995 however I it's worth a very long look.

I am interested in taking very long looks. Thats how I got started in this. I have no past experience with photography or AP. I had an old Fuji digital camera that I used to take pictures of ducks and geese (mainly so I could later carve and then paint them) but other than that photography was just an after thought. Then I happened upon CN one rainy day and started reading about what people were doing and roughly how they were going about doing it and thought AP is for me. Its certainly not easy to get started, there is so much to learn, but thats why I like it.

I appreciate everyone's post so far. The CEM60 looks interesting.  It makes the CGEM-DX look overpriced.  I haven't even started looking at Losmandy yet.

I just put my Atlas AZ/EQ6 on a permanent pier. With 25 pounds of Edge 8" SCT and a CCD camera, OAG, etc. tracking is under .5 arc seconds. I'm not sure that any other mount in the 2K class can do better. It is heavy though and there's nothing wrong with any of the other recommendations you've gotten. I always recommend that someone join a local club and find out what people there are using. That will open a world of mentoring to you even if you never leave your back yard.

The GM811G with lightweight rather than HD tripod is 2795, and many users will no doubt find the lighter tripod easier to carry around and quite sufficient.

So it is either Losmandy or CEM or i add too for AZ-EQ6, will see what you will end up.

My 2 cents... I own a CEM60-EC... extremely happy with it. I know others with the straight 60 and they love it. When needed iOptron's support is excellent.
My buddy just got one of the new Explorer Scientific versions of the G11. I have to say it is a cool looking mount. The tripod is a very solid beast. I'm not certain how close the actual Losmandy product compares... but there are definitely a couple things I like about that mount. 1st I like the traditional equatorial build. I wish I could start on a target "upside down" so to speak and follow a target across the sky without doing a flip. 2nd there are bubble levels on both the RA and Dec axis which makes finding your zero position extremely easy regardless of how level your mount is. They seem very accurate.
The downs for me on the ES-G11.... no gps... you have to enter your coordinates when you fire it up. Not sure if it remembers the info given. Also there is no polar scope, though I think one can be added as an upgrade. But in the days of Pole Master who needs a PS? IOptron's come with a hard case for the mount the ES doesn't. Finally, side by side... looking at the graphs, mine tracks better.
I failed to say... iOptron's polar scope is very good. So with your limited backyard field of view for a proper drift... that PS will do wonders for you... or just buy a Pole Master... lol.
IOptron is having a sale right now and they will sell you.. if not give you a plate for your pier. Talk with them.
As to the wait list... not sure about iOptron but Losmandy has one for sure. The ES version I think is available. I should say my buddy has also gotten very good support as this is a new product for them.

Edit... one other thing to consider... the CEM60 has through the mount wiring with 4 USB, 2 power ports and a ST4 port all on the DEC. Cable management is a whole lot nicer this way.

Good luck with your decision!
Will

Losmandy makes a GPS for the Gemini -2 versions of their mounts. I have it, works perfectly however it's really not that necessary. If you have a Smart Phone and a cell connection you are in business.

Thanks again everyone for your 2 cents.

I am having some difficulty waiting on my pier plates to show up. 35 day lead time is painful. I want to see how the avx does on a pier, overloaded and all. I talked to my wife about a $2500 dollar mount and she immediately began to scream, then foam at the mouth while speaking in tongues. Since that went over ok I may try and push and build a second pier and keep both mounts . I could then get a small refractor for visual.
