Hello ladies and gents,

 

I stumbled upon this very light, and seemingly well-machined mount, with belt-driven slow-motion controls. The given payload seem a bit optimistic, though.

 

With 4" bearings: http://www.herculesoptica.com/4.html

 

With 2.5" bearings: http://www.herculesoptica.com/25.html

 

Has anyone ever tried one? I'm tempted to experiment with it with my 4" f/7 frac.

No, but my interest is piqued! Let us know if you bite.

That is an admirably simple design. I'd rather see a 5/8" x 11 center hole to match a good surveyors tripod, particularly on the larger bearing model. I hope it proves to be a good product as it should find a place in the market at that price. Please report on it here if you pick one up.

Interesting. If they actually work well with even half of the advertised "bearing capacity", those are really light and inexpensive,,,again, IF they actually work well.

 

The pictures with scope have me wondering about the location of the slow motion controls though -- seems like it would be pretty awkward to use both at once (with two hands).

I don't see it as a disadvantage, on the contrary, as I would be using it with a sturdy photo tripod.

That's exactly what's giving me pause about buying one. Maybe someone else would like to play the guinea pig? :)

Great! I'm eager to hear about how it performs.

Be sure to give us your thoughts once you use it! Very curious.

Considering you're going to use it with a "travel scope," is it safe to assume you got the smaller model?

I saw these quite some time ago here in the UK from 365astronomy.com

 

Please let us know how you go on with this.

Following the Hercules mount to the Chinese sellers page I found a few more interesting alt-az mounts on astroshop.cn. For reference the California made SV M1C has 2 inch disks while the M2C has 3 inch disks. The Chinese store has a 2 inch "Tektour Aim" mount at USD 146 (same as M1C), one larger "Tektour Inox" with 4 inch disks (a bit larger, heavier and more expensive than the M2C at USD 340 without a clamp) [1]. Finally and probably the most interesting is an unbranded one with two substantial 6 inch disks at a 90 degree angle (and only 8lbs without a clamp?). Would this have to be compared to the DM6 (I assume not, as half weight - and the box shape might be more sturdy)? At USD 500 not exactly cheap and no obvious way to order to the US.

 

[1] I am a bit surprised that domestic Chinese prices for mechanical items are not better.

This mount looks very similar (in size and shape) to SW AzGTi mount ... somehow it makes me wonder if it wouldn't be possible to adapt the Azgti motor and electronics to the mech of this hercules mount.

The 2.5" IMHO looks too puny for a scope but would be OK for a DSLR. I ordered the 4" - to carry my 70mm APO and I hope this will reduce the all-up size and weight for airplane travel.

 

I've seen those other mounts before on AliExpress but the thing that differentiates this one is the belt drive slow motion and the light weight compared to an AYO or the SkyTee. At around 8:1 it should be quite useable. While these are nowhere near a DM4 or DM6 in terms of mechanical stiffness, it should suffice for a small scope.

I have the smaller model.  I use it with my WO Z61.  It works perfectly, meaning it (1) holds the scope steady, (2) allows me to switch eyepieces without the scope's moving, and (3) allows me to track in slow-motion up to 140x, which is as high as I care to go with the Z61.  The knob-initiated movements are also fast enough that I use them to find things.  The mount also looks good, which is nice. It rides atop a Manfrotto photo tripod.  I'll post some pics later.

I'm interested in the larger model.  Hope to hear some user reports soon, especially concerning lateral balance with a heavy instrument, strength and stability, and how awkward it is to reach both Azimuth and Elevation knobs at once using both hands.

May be a wile since shipping that mount from China may take 25 or so days...

Well there must be stock, mine shipped the next day. Delivery from AliExpress to here is typically 10 business days. OTOH my Berlebach Planet tripod vanished in transit, and took 9 months to arrive - circumnavigating the globe twice en-route. I had given it up as lost but finally it did show up.

I think I've been "spoiled" because when I order stuff from Agena Astro or Highpoint Sci or Astronomics I get the goodies within 2 Days!

 

So 10 days would feel like an eternity.....lol.gif

Here are some pics of my mount.  Notice the maker has upgraded some of the knobs.  The new ones surely work better than what is in the older pictures.

Here is one with the dovetail clamp, and one with the scope.  The counterweight is not from the maker; it is one I already owned.

Here are two more with the scope. I can use the scope on the mount without the counterweight, actually, but I don't have to tighten it as much with the weight, and it does balance better.

Shipping did not take the whole 25 days, and the seller was quite responsive, to me.
