I tried to download from the website, but I think they are shut down. You can do it from the DC-3 Dreams web site. It is not as bad as they make it out to be. Frank

I just downloaded an ephemeris, so the site does work.

Rather than put a mini pc on the moving side of my AP 1600. I mount a Startech 7-port industrial USB and a Rig Runner power distribution and run two cables through the mount. I house an industrial min

Rick, I elected to keep the mini PC on the stationary side because I connect it to the GTOCP4 via a serial cable. I also connect other stationary items like the Astromi.ch GPS/Environmental sensor, an

AP has a procedure for adjusting the mesh between the worm and the worm gear that will eliminate the play in either axis. The play is easier to detect in RA because of the large moment arm provided by

A go to is not the same as an alt/az pointing that you would use to line up a polar scope in the center of the RA axis on a mount. In a go to the Declination of Polaris is 89 degrees 20 minutes, so th

You would probably have to replace the motors. Frank

AP has an extension for the counterweight shaft. Frank

I’m not impressed with the image, particularly with an 80 mm scope. AP cautions against large moments of inertia. You are moving the center of gravity a long way from the RA axis. Even with good balan

I have an industrial mini computer near the mount that has RS 232 ports that I use to connect to the mount. Frank

Here is my AP1600 quad scope rig. One 250 mm RC scope One 152 mm refractor Two 80 mm guide scopes. Two through the mount power lines each feeding a ten-port Rigrunner power distribution unit. One thro

One computer can handle all of the equipment for two scopes with no problem. Other than camera downloads, most of the interfaces are low data rate. I considered mounting a computer on the declination

I have a side by side configuration mounted on an AP 1600 and the two main scopes each have a piggyback scope. All scopes have cameras and electronic focusers and there are two filter wheels. I have t

I was attracted to putting the NUC on the OTA, but have found no practical advantage. I have two StarTech USB 3.0 7-port hubs on the mount and can download images simultaneously from two 16803 cameras

What price applies if you were already on the list? Frank

I have had occasions where the APCC error message page appears minimized below the task bar. I just right click it in the minimized state to close it. I then select View Error Messages in APCC and the

From the MDL manual: Many cameras produce images that are offset slightly from the nominal starting position. This results in a misalignment of the Bayer pattern, which in turn produces grossly incorr

I live on the coast half way between LA and the Bay area. The sky is fairly dark particularly out toward the ocean. We are blessed with a perpetual water shortage that has stopped all new development.

One useful tool in combating light pollution is the concept of light trespass. The county I live in has a requirement that all lights be shielded to prevent intrusion beyond the property line. Why sho
