The Rayox dovetail saddle (regular price $449 with adapter through Woodland Hills Telescope, with an initial discount for Cloud Nights members) is a breakthrough product that has significant advantages compared to existing systems, especially when working with heavy equipment. If this system had been available earlier, I could have avoided some potentially dangerous situations…

Since I submitted the review, Woodland Hills and Stephen Pizzo made a video that shows the workings or the saddle:

One of them will give the discount code in the Vendor's forum.

I picked up one of these saddle plates and concur with Derek's findings wholeheartedly.

 

I am a height-impaired, aging amateur who is terrified of dropping one of my OTAs as I secure it to my Losmandy G-11 mount. Since I am now retired, if I drop an OTA, there won't be a replacement. The Rayox has reduced this fear factor considerably. It is ideal for my situation.

 

One thing that Derek did not mention is what a joy it is to work with Stephen Pizzo. He is very responsive to answering questions and open to suggestions for potential improvements to the attaching hardware scheme. Stephen has put a lot of work into offering a kit that works well on a myriad of mounts, yet did not flinch when I suggested a minor, yet important (to me) tweak.

 

Bottom line: I am glad I invested my money in the Rayox Saddle Plate.

I've got a box of old bicycle skewers. I use them for jigs and fixtures in the workshop and have often wondered why that cam action wasn't incorporated into a saddle.

 

The click-in feature elevates this product above what I would have expected in a cam locking saddle design.

Hi Headshot:

 

I agree that Stephen was really easy to work with.  He has been talking about a version of the saddle that holds narrower dovetails (Vixen, and hopefully others like AP sliding bars) after this model gets going.

Derek, 

One thing I don't think Stephen realizes is the ease it will be for us "aging" armature astronomers with arthritis. It is such a pain balancing my 11"  then tightening it up. then comes tear down when it is cold and the plate screws just wont budge. Embarrassing having to have someone help break the screws loose. Finally, just one click and it's out. PTL. Called Dr. "D" and ordered one for my G11 and G8.  Thanks again for a great review.

Hi Checkitout:

 

You are right, the Rayox is great for anyone who has issues with undoing the dovetail at the end of the night.  I don't have arthritis and I still find it difficult to loosen the screws if I have used a large scope.

Derek, your review couldn't have come at a better time.

 

After a near miss, I decided to give the Rayox a go. My TOA (something like 60 lbs all in) is hanging on it as I type this. The finish is good and the fit is excellent. Adjustment to suit my Losmandy (I think) dovetail plate was painless. I was able to balance the tube on its axis in moments.

 

Since tolerances are tight in an over-centre cam, I will keep an eye on the saddle's grip as the year warms up.

 

A suggestion -

If it's being used on a mount with lots of trailing cables (in my case a 900GTO.) Once everything is sorted out, it may be prudent to secure the lever with a cable tie, This could prevent it getting tugged into the balance position.

This is the first time I saw broadcast/cine clamp idea transplant to amateur astronomy. It's long overdue. Similar clamps have existed for a long time, and widely. See Kessler, Cartoni, Oconnor, Vinten and many more. It's an industry standard.

Yes, this type of clamp has been employed on photo tripods for many years. It's not new technology, except for astronomy use, and afaic ridiculously overpriced.

If you ever experienced the trauma of seeing 3 of your most prized and delicate possessions slide off of a saddle and crash to the ground, I bet you would change your mind about what a safe and effective solution is worth.  Add up what's sitting on top of your mount and then add to that the fact that for a very long time after such an incident, you'll physically cringe at the thought of it.  I had that happen and I can tell you that as careful as I normally was, fatigue and distraction can happen.  I really love my MyT mount but the Versa-Plate is not ideal for me.  I have a Rayox saddle on top of my MyT now.  It makes it so much safer to mount my rig, I consider it a necessity.  In order to mount anything on the stock Versa-Plate saddle the came with my MyT, it needs to slide in from the front or back of the Versa-Plate rather than being able to rock it into place.  That's fine if you have a refractor using rings because you can easily insert the dovetail and rings first, secure them, and then place your refractor into the rings.  One of my current setups is a TPO 10" Truss RC with a MoonLite NiteCrawler and an STT8300 and FW8G-STT.  It has no rings and the whole outfit weighs about 50lbs.  Yes, I can break it down into components but I prefer to avoid that if possible. For me, even just the RC at 34lbs is heavy in this situation.  Lifting it up and sliding the D Plate into the Versa-Plate safely, without vibrating it and the mount to the point of affecting either collimation or polar alignment, or something even more catastrophic is tricky.  It's also really hard on my back.  With the Rayox saddle, I can much more easily and safely rock the whole rig into the saddle which then automatically engages the D plate and holds it safely.  I have it marked so I can rock it in at just the right spot so it's almost perfectly balanced but it can still be adjusted safely in Balance mode with the lever halfway to closed.  The lever that locks it down is easily closed with one hand and it securely holds everything very rigidly in place.  If the lever isn't completely closed, it's plain to see that it's not yet locked down.  When I think about doing it this way I feel the exact opposite of the cringe that I used to feel when thinking about mounting my rig.  I'm actually testing the prototype of the model that is a replacement for the Versa-Plate and I'm extremely happy with it.  I've been unable to have all three contact points engaged with my D plate on the Versa-Plate and maintain balance in the past but most of it is now engaged by the Rayox saddle and I'm confident that it is more rigidly held because of that.  The functionality is the most important thing to me but the Rayox is a beautifully engineered, CNC machined piece of gear.  The cost to machine the adapter plate and saddle out of high quality strong aluminum and anodize it must be substantial.  I own quick release mounts for my DSLRs and this is a completely different animal.  I think it's worth every penny.

 

Best,

 

Bruce

Not hindered by any knowledge about the subject, other people's work often seems simple and too expensive...

Produce a couple yourself, test them and come back with a not 'ridiculously overpriced' and at least as good product and 'walk your talk' ...

I've recently done some field testing of the Rayox with a Celestron C14 OTA.

 

I see no advantage with a large OTA. It is nearly impossible to see where the OTA is landing into the saddle plate- might be easier with an open truss- the difficulty is visibility. The trip mechanism for the clamp is far too sensitive on my Rayox- it is possible to trip the clamp without griping the OTA rail. This is because the size of a large tube prevents you from seeing the exact position of your rail relative to the clamp. I tripped the mechanism many times before I found the sweet spot and this means you have to place the OTA back on the ground reset the trip & try again- it is really difficult to hold a 42 lb OTA in place six feet up for long. I'm sure this would be easy with a smaller diameter tube but anything above 11" OTA & you might hit this problem.

 

It is also difficult to slide the OTA to balance with a big tube on a equatorial mount as gravity forces the locked rail against one side of the clamp making the assembly really difficult to move.

 

I'm going to be removing the Rayox and going back to rings so I can see what I'm doing.

 

I will use the Rayox on a portable mount with a refractor where I feel it is more suited.

 

You will note from the video with Woodlands presenting the Rayox that only a tiny tube was selected. I would like to see the same ease of use with a very large diameter tube- I think you would get a very different impression of the product.

 

I'm not against the product in any way but I feel that the suitability needs to be carefully established before committing to a purchase.

Can tilt saddle method with the counterweight bar horizontal and the OTA on a small table be used with the Ravox? Would that make it any easier?

I'm sorry you've had trouble with the saddle and large OTA. I realize a much beefed video needs to be made. 

FWIW a great deal of my testing was done with a 230mm F7 Lunt LS230THa. It's quite heavy compared to other similar sized refractors due to the sizeable etalon and housing. It used to take two people to mount however I was able to mount it on my own using the RAYOX. 

 

If you believe the release is too sensitive that ive that is something we can quickly test and adjust.

I'm planning to get a lift table so I can position the OTA on the corrector plate end the raise the entire tube to engage with the Rayox clamp. This will be far easier than having to hoist the big tube in the air to position the Rayox. 

 

I see a way forward with the existing rings for the RASA. I will mount the rings on an ADM rail and use the Rayox to grip the rail with rings attached. The RASA being a short focal length is not so critical of vibration errors so this should be a means to mount both tubes on the same mount.
