My AT Voyager w/ "Manny Myles" Mods!!!!
Posted 08 May 2009 - 06:15 PM
I wasn't happy with the "push-to" ability of the stock mount. I'd have to grab onto the scope and mount at the same time to pan around to a different object.
Another thing I wasn't a big fan of was the way scopes are mounted to the "hockey puck" sideways and having to always turn the focuser (or diagonal) 45 degrees.
I also thought that the tripod spreader, while ok, could have been stronger and gave the mount more support. And the eyepiece tray that AT offered, 1 didn't look good, 2, didn't add support & 3, I did't like where I would have to mount it.
Enter "Manny Myles" (that's his screen name). After searching through the Mounts Forum here on CloudyNights and came across a few threads (csa/montana's specifically) that had the Manny Myles Mods done to the AT Voyager mount. his modifications answered ALL of my negatives I thought of the stock AT Voyager.
Manny (Dave) was VERY communicative and answered all my questions. I ended up ordering an eyepiece tray with 3 2" holes and 6 1.25" holes. I also ordered a PhAT RaAT w/ Pan Handle from him.
After installing everything (everything you need to install comes with the package, by the way). Boom, mount was sturdier, push-to was easy, you don't even have to touch the scope.
Manny's (Dave's) work is proffessional grade. The paint job he did matched the painton the Voyager exactly, and the eyepiece tray was light weight and fit perfectly. (the welding job was spot on also )
Manny Myles also sells another bracket, I forget the name, but it's installed at the lower end of the arm of the Voyager, which also helps with balancing and the overall sturdiness (is that a word?) of the mount. He also has a bracket with just the Pan Handle for push-to'ing.
Now my AT Voyager mount is modified exactly the way I wanted thanx to Manny Myles.
He gets a "5 bow rating from me:
Well, here are some (a bunch actually) pictures.

CG of scope is quite a bit above the alt axis. This potentiates the dreaded scope flop associated with using photographic mounts. How is this an improvement?
In English please.
I'm no scientist, but it's a lot easier to mount, the scope is in a better position, balancing is a lot easier, overall it's sturdier. And I have less worries now about everything falling over then I did before. What's scope flop? Sounds like something Viagra would take care of.
Are you claiming the scope is more likely to fall over in this position mounted on the bracket?
Doesn't seem like it is. The overall balance of the set up is a lot better then before. Before, EVERY time I would "push-to" another object the mount would want to fall over (I call that not being sturdy). Now with the bracket/handle it's firm on all 3 legs (I call that sturdy). Solved my problem.

With the scope in the factory placement, the scope is further away from the center, with the bracket it moves it forward and inward towards the sweet spot, not exactly perfect but much better than factory.
Having the Bent Bar on there gets it even closer to the center of az rotation, helping get the scope's weight centered on all 3 legs.

Scope flop: balance the scope when level and when pointed up it will tend to rotate backward(flop). It'll do the same thing when pointing down in the front but that's not too common in astro observing.
I can attest, with the tension knobs on the Voyager that wasn't/isn't an issue, well it wasn't for me. After your post before, I mounted my TMB92SS again and messed around with moving it, up/down/left right, tried different EP's, etc, etc. I didn't have any worries or scope flop. It was a lot sturdier then before, especially in regards to "push-to'ing".
Manny's brackets are a professionally made item and do what they say they're going to do. No worries about exacerbating scope flop.

I think the brackets look very nice, but I agree with Luigi that it appears the scope CG is above the alt axis. I know from using the Celestron Heavy duty Alt/Az mount that the weight being above the alt axis doesn't work to well. I would imagine scope flop would be more likely with a heavier longer scope than yours.
Coparing those 2 mounts is apples to oranges. 2 different mounts with different designs.
If the Celestron mount you're talking about is the one I'm thinking of.

Nice pics Randy and Kudos to M2 for coming up with the idea! My Voyager is still in the box as farm work has prevented me from doing a first light this weekend.

With a well balanced setup, virtually no friction is need to hold any position of the scope and the movements are very smooth and easy. This is one of the usual goals in designing a telescope mount, and one that the standard Voyager attends to by placing the center of the OTA on the altitude axis. Your mod undoes this, which might be OK if offseting benefits outweigh this consideration.
Oh yeah, thanx for mentioning balance. The bracket makes balancing the scope A LOT easier.
