I bought one back in Augusto, but haven't used it yet. It cost about $42.50, and came with two containers of grease, an artist-type paint brush, and clear illustrated instructions for how to access

My Mach1GTO will be three years old in a few months, and has never been lubricated. Then again, it hasn't been used much in the bad weather we've been experiencing for months. That said, what is the

I agree, give George at AP a call. He recommended their grease kit for my 900 I had a while back. It's comes with two types of grease for the gears and worms. It's a good kit to have.

Geoff When was the last time you cleaned and re lubed the RA and Dec gear trains. If it has been awhile I would service the gear boxes and worm gears. AP has a very nice grease kit. Maybe Marj can

Tyrel Take off the nylon gear and and the aluminum gear underneath. Have a look at the small gear underneath the big aluminum gear. Could be that small gear is detached from the larger aluminum one.

Mistakes were made. Short version, I had a small 3-step kitchen ladder near my scope that I had been up and down a hundred times working on collimation. Tonight I went to fire off a pointing model and

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

Hi Michael. The link I provide just now is not to the apcc installers but to the nasa web site. They are entirely different things. -Ray Gralak Author of APCC (Astro-Physics Command Center):

All US government sites (that includes NASA sites) must have been made TLS-only by the end of CY 2016. In addition to that, TLS 1.1 or higher (such as the newer TLS 1.2) are the only versions these

Hi Ray I thought you mentioned in an earlierpost that the website is http: and not https: Best Regards Michael Hambrick ARLANXEO TSR Global Manufacturing Support PO Box 2000 Orange, TX

Hi neyle , I have no idea why it would not open on your computer. It is probably related to a problematic Windows update. However, here is the link: https://ssd.jpl.nasa.gov/horizons.cgi#top -Ray

Ray, The JPL Horizons Ephemeris will not open. Any suggestions. Thanks neyle sollee

Last night I was able to image for 6 hours or so, including some imaging of Atlas C/2019 Y4. I used the opportunity to try out the Horizons software, so I downloaded the ephemeris data for Atlas.

Even if the mount *is* well polar aligned there can be pointing errors from other sources. Once you plate solve+sync that will change the relative position of the Park positions. I think you just

Hi Mikko, The part that I think needlessly worried you is that after a plate solve + recal you expected the mount to return exactly to the marks where it started. If the plate solve + sync changes

The pier/tripod is not perpendicular to the earth's center. * The mount is not "perfectly" polar aligned * The optical axis is not aligned with the mount's mechanical axis. Well, as said nothing has

Ron if I understand correctly what you say, that's exactly what I used to do before this saga started. - Mikko

Hi Cytan, I don't think it matters, but I would use the second way. You can have APCC turn off tracking after unparking from the Park tab if you don't want tracking enabled. The option is a checkbox

Hi David, Thanks for reporting that, I'll look into it. -Ray Gralak Author of APCC (Astro-Physics Command Center): https://www.astro-physics.com/apcc-pro Author of PEMPro V3:

Hi Geoff Try looking on the Astro-Physics website. They have a lot of information in their Support section. There isa collection of documentation for their legacy products there. I don'tknow if the
