Re: RAPAS reticle orientation
CHRISTOPHER FORD
Yes this is a fairly easy fix and AP, but I hear of this happening so often that I feel it is a minor design flaw in the RAPAS. That small set screw never seems quite tight enough to prevent rotation and misalignment of the reticule if knocked, especially as the illuminator makes such a wonderful lever. A beefier set screw or several of them would help. When the reticule is aligned, it should be totally imobile. (Like drop on the ground imobile) I have two RAPAS and have accidentedly knocked my reticule out of alignment multiple times, even through something as simple as the pressure on the illuminator of draping a cover over the telescope for the night. It risks souring the out of the box experience as evident in this thread. (A friend of mine has just received a new RAPAS and experienced the same also) Chris

Yes, when looking down into the eyepiece the 0/24hour division on the reticle is parallel to the objective tube and points directly at the objective end.

Hi Don,
Is 24h position pointing directly toward the RAPAS objective lens direction in your scope? Thank you. Donghun

Re: Pictures of special angled pier for A-P mounts to avoid Meridian Flips
Robert Chozick
That is very interesting. I had to visually recreate this with my arms to understand what you are doing. The only failure scenario is hitting the ground. As long as the whole setup clears the ground in any position and does not touch the vertical base holding up the mount I would think you this could go on for days turning around at any declination. It would have to have a long arm to clear my 155 EDFS, field flattener and camera.

Re: RAPAS reticle orientation
Sounds like the set screw locking that round ring which the led reticle threads into has come loose and the ring has turned. You can simply loosen the set screw located in the body of the RAPAS at the rear just below the collar and reposition it then re-tighten the screw. Don A

Re: Doing GTO an object on "wrong" side of pier?
Alternately, you can also set the Meridian Delay from the Ascom driver if you want to keep your computer connected. Don Anderson

If you are using ASCOM driver, try unchecking: "Keep Mount Time Synced to PC Time (Recommended)" This may prevent from your Meridian Delay set by hand controller from being reset by your PC. Peter

Re: Carrying Case for AP1100
John A. Sillasen
Yes, please. I'm currently contemplating a single case with lift off cover rather than hinged or dual Pelican cases. For the weight, the one time hoist of both pieces, the price is less than 2 big 1600 series or 1550Ms. I know it's a fair heft but the cabling alone may be worth having one case. Then again my mounts are in sheds I can't reach without the mounties or at least a dog sled until some melting occurs.

I got a case from ScopeGuard, unfortunately they are no longer on business.

I use a case with pp honeycomb sandwich panel custom-built by a local manufacturer for my 160EDF. The weight is much less than the original one and it works great for hand transport. I will do so for the 1100GTO that will arrive in a few weeks. Seems like you already decided with Pelican and just FYI. Yasushi

Re: Pictures of special angled pier for A-P mounts to avoid Meridian Flips
astrotrf2002
Robert,
Thanks for your reply. > An A-P mount will not flip unless you tell it to do so. Well, I'm no expert on this, but I do know that mount-control software wants to know whether it's controlling a GEM or a fork. So my conjecture is that there are differences between merely *ignoring* the meridian (a la the A-P) and behaving as if there is *no such thing* as a meridian (a la a fork mount). I'll admit to being unable to come up with failure scenarios, though. My intent is to use the AP1600GTO's 90-degree declination holes to attach the mount to one of these bent piers so that the RA axis is colinear with the upper section of the pier. I don't want to find out the hard way that this will lead me into unnatural positions such as pointing the scope toward the floor (which would not be good for my main mirror and the mirror mount).

I use Pelican cases. I use a 1620 for the RA assembly and hand control and a 1610 for the Dec assembly, counterweight shaft, GTOCP3 and DOVELM162. I do through the mount cabling in the field, but find set up and take down as separates is not a big deal.
