Ahhh My misunderstanding. I thought there were two new dovetail bars that were joined longitudinally to form a new very long Tri-bar. Thanks for clarifying! Bryan ---In ap-gto@...,

Two nights ago I tried running APPM. It started off going to zenith and solved the 1st point ok. When going to 2nd point (DEC = -20, HA = -2.8378) it slewed 360 in RA (the OTA went below the mount

I drilled and tapped four new 1/4"-20 holes in the bottom ofeach of the adjusters and then drilled and countersunk four new 1/4"holes on each end and the center of the long dovetailbar. ADM stocks

Chris Are the two ADM bars permanently connected, e.g. welding, or just held in place by the saddle. Bryan

Thanks VERY much for the information, Chris. Bryan

Nice! Where did you get that cool astrograph? Rolando

ADM Accessories has Losmandy-style tandembars. I took their longest bar and made a triple OTA bar with twoadjusters for the outside OTA's. https://photos.app.goo.gl/o8LVpOhSZ0INFllv2

The instant the CP4/3/2 detects a motor stall it kills theaxis motors. Believe it or not, axis position and sky alignment hasnot been lost. The CP4/3/2 knows exactly where it was pointing the

Thanks for the explanation. That is very clear. -Wade

Off-topic, but I am intrigued by the twin OTA setup. Which mount ... 1600? How log is the transverse bar and is it custom? I am interested in mounting two OTAs on my 1100 to image different FOV. I

The reason why you need two connections is that APCC and the ASCOM driver use the ASCOM protocol to control the mount. Unfortunately there are no ASCOM commands to operate our encoder functions and

Yes, right now you will need two connections. This is something that Howard and Ray are feverishly working on and this encoder utility will be fully integrated into the next build of APCC. Hang in

I have an 1100 with encoders and last I saw, we are still supposed to use the separate AP Encoder Utility to set the Home position and to go home, not the "Home" tab in APPC. Unless you have two

You will ALWAYS lose your reference position when you loosen the clutches and move the scope manually, whether the mount is on or off. Let's say that you don't know where your mount's internal memory

No, the clutches simply allow the scope to move around, but do not move the geartrain. The encoders are attached to the geartrain. When you move the scope, you ar NOT moving the main shaft around

I use to own a 1600ae, 1100 now and the AE kit is on the way, and It got lost when I loosened the clutches and moved it WITH THE MOUNT OFF Now there is a homing function in the AE utility that

That’s a point that I’ve not been clear on. There have been discussions on Cloudy Nights about the AP mounts with absolute encoders, and the assertion from people with other mounts is that the AP

If you have an encoder mount, then yes, the encoder will drive the mount back to the position you started from because the encoder is attached to the main shaft. With non-encoder mounts there is no
