I am going to assume that the only fair way is that everyone only gets to sign up once.

And only one entry per household.

And that cheaters will be disqualified.

I also assume that it would only be fair if existing Stowaway owners wouldn't be allowed to play either (darn!)

And that entries must have a verifiable name, verifiable email address, verifiable phone number and a verifiable physical address to qualify.

Did I miss anything? LOL

Re: Preventing Pier Crashes

Ray Gralak
 

It can happen in a counterweight down position.
Can you post a few pictures from different angles of this scenario?

At present, I don't think there is a software solution. You might be able to first slew to park 3 before doing another slew or parking to park 1.

BTW, are you using Park 1 to fit the setup under a roll-off roof?

Hi Alex,

Are the collision zones you mentioned in counterweight-up or counterweight-down position?

It can happen in a counterweight down position. For instance, last night, I was imaging m16 in the south on the east
side of the meridian. Clouds rolled in right before reaching the meridian so I decided to call it a night and I parked the
mount (park position one). The RA axis was essentially in the correct position so it only had to move a small amount
to put the RA in the park 1 position. The DEC had to swing the scope from pointing south to pointing north. As it
made this transition, the camera swung down as the scope rotated around and as it approached the zenith, the
camera crashed into my pier as it protrudes too much for the scope to safely reach the zenith.

What I want to do is define this zone of death so the scope will never attempt to slew through this zone.

Re: Tool for saddle clamping

Woody,

 

Anthony mentioned to me years ago he was working on a tool for the knobs, and with my aging hands, it has been a delight to use.

 

And the price is most reasonable when you consider the quality of the machining.

 

Yours truly,

A small strap-wrench would probably also work.  They have lots of leverage and the rubber/plastic parts don’t mar the aluminum.

 

But I’m confused.  All my AP knobs have a hex socket in the middle of the knob.  That said, all mine are at least 6 years old.  So maybe AP has recently changed to the solid knobs with no hex socket in the middle.  Too bad.  Although I’ve NEVER needed to tighten anything that tight.  But I can see perhaps needing the hex key to loosen a stuck or seized knob.

Hi Gert

Out of curiosity what is the part number of your dovetail plate ? The knobs look like those on my DOVE15 which has no hex head bolts in the clamping knobs either.

I have had pretty good luck using a jar lid gripper on these knobs. They are simple, cheap, and effective. You can find them in the kitchen section of most department stores (e.g. Wal-Mart). I have noticed something interesting about these grippers though. It seems that after a period of time they will lose their "grippiness" and you will have to replace it.

Re: Tool for saddle clamping

Christopher Erickson
 

It wouldn't be too hard to CAD-up and 3D-print a slip-over knob that would allow for some additional hand force to remove a stuck knob that doesn't have the Allen key socket.

AP's dovetail lock design is the best of any I have ever seen. Angled brass pin with force being applied to a small area on the dovetail bar. Allowing enough targeted force to really clamp down, but without damaging or distorting the dovetail bar. Dovetail brackets that spread the force out along a longer clamp area or worst-of-all, along the entire length of the side of the bracket, aren't nearly as secure and are at much greater risk of a dovetail bar sliding unexpectedly in the bracket, and inviting disaster.

Using a tool to tighten?
You have to be very careful as to not over tighten.
A few years ago I acquired a previously owned SB Paramount ME.
The owner had mounted a 16inch RCOS on it and had over tightened the
Versaplate knobs, bending and ruining them.
