*sigh* Gotta sell the AVX... which ALT/AZ??
Posted 22 June 2013 - 02:42 PM
So the AVX is up for sale. So what alt/az mount should I be looking at to replace it? I have the Vixen Porta holding my ED80 f/7.5. I still have my Orion 90mm f/10 tube. So what is a step up from the Vixen as far as sturdiness?? I need a point and go mount, but as heavy-duty as the AVX was.
I welcome any and all suggestions.

I am kinda heartbroken over the AVX. It was a nice mount!! It is the hottest technology I ever possessed in the astro hobby.

What I'm interpreting here is that it's too much hassle to align the scope per the manual at your observing site (back yard?). But you'll have that problem no matter what kind of tracking mount you get.
So look at this another way... All you have to do is set the DEC sometime while the scope is level. After that, you can plop it down in the back yard, use a compass to aim it (if you can't see Polaris), and then make sure it's level. Just loosen the clutches a bit and move it manually. If the scope is balanced, it'll track fine when you let go. Then use the hand control for fine control. You'd be amazed how well this works for visual!
In other words, use it as a manual tracking mount, but the GoTo (and alignment hassles) will always be there if you want.

I have the DSV-1 and DSV-3. I like them much better than my Vixen Porta or Takahashi Teegul. The DSV-3 can be optioned with encoders so that you can add a Sky Commander and enjoy accurate push-to.
These are not overly expensive mounts, either; just a hair more than mass-produced units like the Vixen or Twilight II.

At home, we set up on our driveway. One time, after getting a good polar alignment, I marked the position of each tripod foot with a magic marker. Ever since, we just set the feet on the marks and we are polar aligned well enough for visual. If we set up on the lawn, I would mark the foot positions with small stakes driven deep enough to clear the lawn mower blades.

as for doing a more proper alignment with no polaris in view, my suggestion would be to first do an alignment and ASPA where you do have enough sky, maybe at a park. make sure your mount is leveled accurately. this will make sure you have a pretty close ALT setting for your location on the mount, after that all you need to do is make sure your leveled good and use a compass to point north and a 2+4 will get you great goto's from there on out.
my backyard is pretty small and has lots of trees and i often end up skipping stars in an alignment because they are not in view, i'm fortunate that polaris is in view but i don't do anymore than make sure its centered visually down my polar axis bore, sometimes i even forget to do that, i just know where to point the north leg of my mount because i've set it up so many times.

I decided to list it on ebay and see what becomes of it. Maybe it won't sell and I will be stuck with it. We shall see.
