I'm thinking of getting one of these for my SkyWatcher EQ6 Pro mount: http://www.admaccess...ual_Saddles.htm It would replace the stock Vixen saddle.

For the bar I was thinking of getting one of these: http://www.admaccess...s_Universal.htm (31")

My current scope is a Orion XT10i reflector, but due to the thin Vixen bar it's wobbling quite badly when touched. I'm imaging using this scope and notice quite a bit of flexure on 5min subs. Would this replacement cure this and provide a more stable platform or am I just wasting my money?

I have them both and the extra rigidity is noticeable. You cannot go wrong. Just ensure you get the right puck.

[Zodiacal_Light]

Which scope are you using them with? I checked and my puck is the newer style.

[m.tweedy]

C11 and NEQ6 Pro

[Zodiacal_Light]

Thanks. Another thing I'm wondering about, what's the total weight of your setup like?

[m.tweedy]

HEAVY about 20 kg fully loaded

[Zodiacal_Light]

WOW, quite a setup!

[m.tweedy]

not exactly grab and go is it.

[Zodiacal_Light]

Depends, how strong are you?

[m.tweedy]

20 kg for the scope, 20 kg counterweights, 21 kg mount head and 10 kg for the tripod and pier. Too much for me I am afraid.

[dmahon]

The NEQ6 (inc. tripod and 2x standard counterweights) is 33.7Kg, without the scope, so that lot will be heavy!

EDIT: (Just) beaten to it.

Something to consider is the tube rings, will they still only contact on a single point on each? I dont see moving over to losmandy mounting with a single attachment really helping that much with stability as this is still going to be the weakest point.

[Merlin66]

For the C11/ NEQ6pro/ Spectroscope combo I changed to the wider Losmandy dovetail and a mandatory Safety Stop bar.
The saddle on the NEQ6 was also upgraded to the much better Geopiks version - this clamps across a longer length of the dovetail than the original SW clamps screws etc.
I've been using this set-up for the past year with no issues/ no problems.

Yeah, I'm considering getting some Parallax rings later on. My main problem now is that the current dovetail only supports the middle part of the scope, so the tube flexes. A longer dovetail should support the majority of the tube.

Fantastic setup Michael .

I got the ADM saddle upgrade for my EQ6 and think it has been worth the money - adds versatility and provides a bigger gripping surface area.

Michael: Don't want to hijack the thread, but noticed that you have the EVO counterweight shaft upgrade on your mount - has this been a worthwhile upgrade?

[Zakalwe]

I wouldn't trust a big OTA like the C11 to the standard puck, especially if you are using the smaller dovetails too.

I've upgraded mine to the ADM. Pricey for what it is, but it makes a heck of a difference. Although I haven't tried DSO imaging on the C11, i do feel that the EQ6 is on its limitis with a such a big OTA. The slightest wind will cause it to move, though if you are in an obsy then you would get a lot of protection

I'd also be interested in this. Again, it looks like an expensive upgrade, but the standard counterweight bar on mine "flops" at a certain angle.

[ampleamp]

another +1 for the ADM puck/saddle, an excellent combination imo

[dmahon]

I'd wait until the puck sizing problem is sorted though (some of the recent ones, including mine, haven't fitted - they are about 2mm too large).

I have a temporary machined puck that does (but I don't have an imperial allen key so that I can switch the saddle onto the puck - have ordered a cheap one from Amazon)

It may look (and probably is a bit expensive) BUT I am placing up to 20 kg of counterweights on it. It is a wider diameter (25 cms) and feels right. The old one started to bend and that's not good. WORTH EVERY PENNY (and looks good). Just remember that it does not slide into the body of the mount but is unscrewed when stripping down the mount. When you consider the cost of what we have swinging off the other end it does not seem so expensive after all.

[billhinge]

Believe it or not I have a C11 on a CG5 with the ADM saddle and Farpoint Losmandy dovetail. Quite a noticeable improvement, enough to do planetary video

stick some sorbathane blocks between dovetail and OTA and they will dampen your tube vibration too
