Desert Sky Astro DSV-2 questions
Posted 17 May 2012 - 10:02 AM
I have been looking for a good alt-az mount for my ES102ED for under $1000. I found the DSV-2 and like its slow motion controls and the balance system and have some questions...
I am wondering about the smoothness of the motion when not using the slow motion controls to pan to an object and when tracking an object in the eyepiece. How it compares to other mounts like the Unistar Deluxe or the ES Twilight II.
Also how smooth is the tracking using the slow motion controls? Is there backlash or jerkyness?
How will it handle a scope of this size: ~33 in long and 15 lbs when loaded with a large eyepiece? How fast would the settling time be when tracking with the slow motion controls?
I plan to use the mount on a Mead field tripod with 2" legs.
What is you impression of overall build and quality?
Thanks for your help.

Well I should have one in a few days. Bought a DSV-2 from the classified section, so I will be able to report back with "real life" experience, rather than my unfounded speculation. :o Gotta find a surveyor's tripod for it. You guys have any recommendations for the tripod?
I don't have one but am interested in the DSV-1 and 2. But I don't think it has any slo mo controls. Push the handle, totally tracking by hand and eye and, if balanced, it stays put. You can adjust the axis friction to "taste" to get a certain level of firmness to the "hold" if I understand it correctly. But, again, I do not have one, just gathered this from reading at their site and the few reviews I could find on the web. Hope this helps.

The QBS system works quite well, you just have to remember to lock the altitude brake. The used one I bought only had two of the day glow dots to mark the velcro strip so I ordered 5 more from Desert Sky. These are placed on the top of the QBS bar to mark the setting for the counterweight, at lightest and heaviest. Works well to keep everything in balance. Once such balance is achieved with your set up, you can move your scope around very easily by hand, for sweeping the sky or if you need to nudge it quickly in one direction or the other. Let go and it holds very well, no vibrations. Use the slow motion friction controls to keep your subject in view as you're looking through the scope. No backlash but there is a small amount of play when going clockwise-counterclockwise with these controls, as is to be expected. These slo mo control knobs are placed close together and on the front so they are easy to grab and move between as you keep your eye on the eyepiece. That also makes it easy to show friends, family, public, how to use the controls to track, when they are looking at an object.
I recently acquired a Celestron C6 SCT which weighs fairly close to my 120mm refractor but I haven't really tried it out yet on this mount. I am still getting it set up with a RACI finder I got for it, etc., but it, too, should work well on the mount. As mentioned, I have the DSV-2 sitting on a Bosch surveyor's tripod. This DSV-2 had the 5/8 mounting hole which matched the attachment bolt on the tripod. I tighten the DSV-2 down and can just "grab 'n go" taking the tripod and DSV in one hand when putting it away or in the back of the Subaru. I usually leave the QBS installed. So it works great as a grab and go setup. The nylon strap that came with the Bosch tripod doesn't work very well since most of the weight is now on the end with the DSV-2 but I will try to address that with a nylon carrying case or something.
It is a keeper. Glad I bought it and find that I am using it most of the time. I'm just getting back into astronomy after years away and attempting to learn the sky.... when I can see it (lotsa smoke in my town lately) and this mount is definitely a great "grab 'n go" solution for my needs.
Hope this helps ! Good luck !
