Twilight I Mount with ES102ED
« on: December 27, 2017, 11:34:12 PM »
When I use my Twilight I the azimuth slow motion control gets in the way when I want to look at anything about 50 degrees above the horizon. I don't want to tilt the arm of the Twilight into its angled position, because the scope then seems to heavy off center. I have just given up using the slow motion control and simply remove it. What does anyone else do?

Where is the Saddle Locking knob location? Top or Bottom?

Can you upload a photo showing the problem?

I went on line and found some short (2-3") metal knobs. Replaced just my AZ axis and it works great.
My scope never hits it now.

I'll try to remember where I bought them and post it.   I think ADM may also have some.

Yes, like these from ADM. Highpoint has them

You can unbolt the part that attaches the arm to the base. That is, unbolt the plate above the slomo control. Once you get it off, there are bolt holes that allow you to rotate the arm 45 degrees relative to the slomo cable, and bolt it back on.

That would be great. I've have thought about finding real short knobs, but I also find just pushing the scope works pretty well.

Thanks. I'll take a look.

You can just get a shorter cable also. Agena has a 6.5" one http://agenaastro.co...handle-6-5.html

This seems to have worked. I can now get quite a bit higher. Not quite to the zenith, but I very rarely look that high anyway. I just don't like the contortions at my old age.

Most people face the scope the other way on this mount. That could be part of the problem.

I turned it around on the Twilight I. I'm not sure it makes much difference, but it might. On the UniStar Light in the background I have a scope on that side and don't mind it at all. I guess I just like the scope to mount on the right side, because of the weight when lifting it into the vixen clamp.

I use the ADM knobs and that will let you go to 65-70° as from factory then you can rotate the base also and have the azimuth from the side and easy to reach with short scope long arms. I usually just extend the opposite tripod leg for more altitude.Peace...

A little off topic here. How well does your Twilight I perform with your ES102ED? Is the mount stable enough and is the settle time acceptable? I have a Vixen Porta 2 on the heavy duty tripod. It's rated for 20lbs but some say that it's not stable enough for anything more than an 80mm scope or any scope with a length longer than about 20 inches. But, the Porta 2 looks more robust than the Twilight to me.
